Toyota EGR Diagnosis Tips and Repair Tips

A Toyota master diagnostic technician shares Toyota EGR diagnosis tips and repair tips for models equipped with the latest generation EGR ( Exhaust Gas Recirculation)
In this video I start a new segment in my channel on how professional mechanics approach diagnosis. The key aspect of any diagnosis and repairs start with the 3 Cs. Concern, Cause and Correction.
First we will look at the concern which in this 2010 Toyota Prius. The concern in this case is a vibration or shudder at low speed\low load when the gasoline engine is running.
I will show you how to isolate the EGR system temporarily to verify that it is indeed the cause of the problem with this Prius.
I'll also cover the differences between professional mechanic approach to repairs vs. DIY approach to repairs. The car being a customer car changes the approach. Most DIY mechanics will understand that some repair attempts on a budget might be short term or can have a nature of trial and error and are willing to deal with issues not getting resolved right away because they are not incurring labor charges.
However in the case of professional car repair customers pay mechanics full labor cost to fix the car right the first time. So the approach of diagnosis and repair recommendations can be different than DIY. Mechanics can't make decisions for customers, They can only recommend options and detail the outcome of each so the customer can make a decision.
In this video I'll show you the process of diagnosis and repair of this EGR system in this 2010 Prius. The owner opted to replace the EGR valve and the intake manifold. I also constantly see folks spending far too much time cleaning the ports, the cooler and the valve to a shiny finish but only to have them covered in soot minutes after starting the engine which is normal.
Along the way I will share some mechanic tips on general car repair like making your own magnetic socket.
Also last I will cover the part of this EGR repair that most DIY mechanics miss which actually resolves the problem with the EGR. Simply cleaning or replacing parts does not complete the repair unfortunately.

[@seanbouker6914]

Not gonna lie I'm in the middle of a head gasket repair... I would highly recommend diy people to completely disassemble and clear the whole EGR cooler/valve and pipe leaving up to where it connects to the exhaust... Including removing the intake completely and cleaning out the EGR lines in the big black plastic intake housing.... Mine looked like it was full of black bacon grease... It barely let any air through.... All of the parts from the dealer would cost over $1000 to replace.... I cleaned it out with brake cleaner 2 years ago for $30 and it's been fine ever since... Mine had 250k at time of cleaning... We're at 300k now... No issue

[@brarautorepairs]

Replacing it is the correct repair for the EGR. The newer part has an updated design. I tried cleaning EGRs to help save some money but I watched the older version being "lazy" switching from open to closed under load. This behavior went away when I replaced the valve with a brand new one. These parts do wear out.

Thank you for this most well done diagnosis and maintenance /replacement video. You are the best for Toyota (DIY) techniques. The dirtiest aspect of combustion can not be solved by "clean gasolines" or " EGR Cleaner in a bottle". Circulation of dirty exhaust gases requires periodic cleaning of the recirculation system. Thanks for educating the Toyota DIY nation with this fine video.

I would just like to thank you for your informative video, my 2010 Prius was suffering from a very rough tick over, and not sure what the cause was, until I blocked of the EGR outlet like you did and the car went back to running normally. Spoke to the local dealer for a price for the EGR valve and was quoted £300+ UK pounds, I had found the part number for the EGR kit you mentioned and they are £52 UK pounds, My car has been into my local dealer today to have the EGR kit fitted today and my car is now running great again, the local dealer wasn’t convinced on my (your) diagnosis of the problem as they have never supplied and fitted a new EGR valve to Prius. I have got the old EGR valve off them and sure enough it is stuck open to the point I can’t push the valve back to the closed position. Thanks again for a great video.

[@ingalway]

Hi. Did you buy the EGR kit yourself and then take it to the Toyota dealer and they fitted it for you? How much did they charge to fit it? Thanks

I know someone with an 09 corolla with this issue. Car would rough idle, stall at stop signs, and vibrate. They spent 2000 dollars trying to self diagnose, and local mechanics, just to find out after replacing everything from catalytic converter to a MAF sensor to spark plugs to intake manifold gasket to 02 sensors to fuel pump. Crazy that even the Toyota dealership didn't catch it. I love to see you talking about older Yotas. My Scion xA is a 2005 and my Tacoma is an 04. I'm very glad you are not ashamed or afraid to express your Christian beliefs. I respect that greatly. Thanks again for another awesome video.

Great Video. I really enjoy learning how automotive professionals tackle diagnosis and repair. I'm not much of a DIY person except for very minor stuff (like adding the tire pressure dashboard reporting unit to the TPMS unit on my 2021 Rav4 Hybrid) but I always learn something new from your videos no matter what is being discussed. The electrical tape over a socket was a real "hidden gem" in this video. Keep up the good work and my best wishes for the continued success of your channel. PS. Please let your wife know that we appreciate her "behind the scenes" work as production manager. Your videos are always professional grade and "well polished". Regards, Ed

Having a third gen Prius myself, this one really got my attention! I had heard about the EGR cooler problem and didn't know what to do about it. I had not heard of the valve problem. I see the valve from the dealer is not much more than the Rockauto price, so if I have to replace it I will go with the Toyota kit from the TSB.

Love this video! As a dealership mechanic, I get all the young "recently certified": techs to work with me for a few weeks. Most are so anxious to just start replacing parts when it's very obvious that it appears faulty. I tell them no, we are going to look at everything else related before we start replacing parts. They always ask "Why?". I tell them "How would you feel if you brought your $60K truck to the dealership with a problem and it wasn't fixed right the first time?" In my experience, and probably yours too, most would rather pay a bit more and wait a bit longer to have it done right the first time.

[@TheCarCareNut]

I hear you my brother! People pay top dollar for dealership service, it’s essential that they get top service at the very least.

Callbacks are demoralizing for everybody involved. Everybody ends up with some but the best end up with the fewest. I don't remember everything I fixed but I remember everything that came back on me. (Electronics, but same thing.)

@@flagmichael I've had a few in my 40+ years, but one still haunts to this day. I had a 2013 Ford Fusion Hybrid in the bay that would go into limp mode. The car only had 489 miles on it and the customer was very upset. The problem was intermittent so we only had a limited amount of time to diagnose when it acted up. We went thru every single hybrid part, module, pin connector and it would not yield it secret. After a little over a month, multiple Ford engineer visits, and a customer who threated legal action against the dealer the car was bought back under the lemon law.

I totally agree with you about always replacing a part. In a shop setting or doing work on the side, it never works out on my side to clean the part. I don't ever get come-backs when I replace the part. The initially client complains about the cost, but they always return to me again since that last issue they brought to me was fixed the first time. Thank you for doing these videos. I know they are time consuming. Thank you for sharing your knowledge and experience.

Did you ever clean or replace the egr valve ?

[@EvzenKovar-i5p]

Did the EGR myself last week. 2012 Prius V with 123K. Absolutely needed the cooler off and soaked. Completely blocked with deposits to the point I had to fish fine wire through each of the small passages. Also… found a huge pool of oil in the intake manifold below the throttle body. The PCV valve design looks like it has much to be desired. Replaced the valve and next oil change I’m going to reduce the amount of oil I put back into the crankcase from 4.4 to maybe 4.1 quarts. Gonna see if that keeps it from sucking oil like it did. The EGR system cleaning really has the engine running smooth now.

[@JohnnyV523]

it would be nice to watch the video before going to Toyota. My 14 Prius had similar symptoms at 160000 miles when I took it to Toyota for diagnostics. The service advisor told me my Prius had an burn oil The repair cost was too expensive, even told me to balance the tire because they didn't know where the vibration was coming from.thank you so much to sharing this info

[@benc1927]

We still have our two old Prius, our 2010 Prius burns lots of oil (common problem) so be sure to check yours. But now we have a P300, P301, P302 engine misfire, so it seems like i'll be trying your EGR valve trick here. We did buy a Tesla and after having it for over a year I must say it is clearly the future. I am never going back to Gas ever again, ever. It's soooooooooo much easier, almsot no maintenance and not millions of little headaches to chase and fail like ICE cars. Thanks for the video, will help squeeze a few more miles out of our Prius (until our next pre-ordered Tesla arrives)

I really appreciate these videos and the detailed explanations. I do like the DIY work but I really appreciate hearing the viewpoint from a dealer mechanic. If I found one like you I'd probably let the dealer do it more, but I've found my dealer has been sloppy and cut corners (they broke the cabin air filter cover and never replaced it; I know because the dealer performed all maintenance until I did the last one myself). I wish I would've had the "magnetic" socket trick a few days ago because that lower bolt was evil. Keep up the great work and thank you for educating me.

Thanks for the nice presentation; a reminder that the Prius is not a DIY project car like the old 1995 Camry is. Cars will never get simpler as we go forward, so I hold on to my old Camry with white knuckles.

[@capnpugwash5403]

Much respect, these eco-friendly cars have become so complex, and every little part is squeezed into a small space usually intended for easy assembly rather than easy maintenance. I am so glad when I used to do more than tinker with cars, sometimes maybe 3 full services in a weekend, you could almost climb inside the engine bay. No computer diagnosis, you had to know if a capacitor was going by the colour of the points spark etc. I could tune a branch manifold with 4 individual strombergs with a length of 1/2 inch pipe, and then put a flow meter on it and it was spot on. But man, the cockamamy stuff you dealing with. Almost stripping half the car to get at one piece. Sheesh.

[@dkcoan792]

Thank you, had a rough start up one morning, the persist. Did the usually route because maintenance wasn’t perform. And will check when today when getting off work.

[@TruckFreak69]

Thanks! I got the rough running at start just the other day, right before I was about to replace the EGR and Intake because of an intermittent code. I noticed some white smoke out of the tailpipe though, so I assumed head gasket. No noticeable coolant loss or mixing with oil though. Is white smoke always head gasket if car is warm?

[@natividadangulo]

Great video! Saved money buying the kit instead of individual parts but unfortunately it also had a blown head gasket. All fixed now!

[@fugazi5150]

I did this cleaning to my 2015 persona series.It was a pain in the ass but I managed to clean it well and got rid of all the gunk.I also replaced my water pump,spark plugs,drain and refill the coolant from the inverter and radiator.Now it runs like a champ.Im on 120K right now🤙🏼

[@orlando2483]

Have the exact car, any links to tutorials about how to get all those things done the right way? Also, did you do the update like AMD suggested? My Prius has 100,000, holding off till spring to get these things done.

Hey, I just want to chime in about my (seemingly) sucess with 2013 Lexus CT 200h. I had watched several other videos that more or less said "Clean the egr system and the cooler." I spent about 2 hours spraying all kinds of chemicals into the cooler, the same for the egr. Put it all back together and it ran *worse* in some ways. I didn't drive it anywhere, just had put it into maintenaince mode to begin burping the coolant system. Pre-cleaning of the egr, I was having cylinder 1 misfires. It was the worse on cold start ups, and would happen periodically while driving at lower speeds (15-35mph I'd say). Post-cleaning of the EGR, the engine was surging struggling to get enough air it seemed like. I took the advice of this video, bit the bullet and bought a new egr valve from Napa for about 270$ (they had a sitewide sale!). Installed it, and now the car runs normal again! Let it run for about 20 minutes while burping the system, took it out for a test drive and it ran wonderfully! (Though the temperature light did come on, we will see if that's because I left it running so long in maintenaince mode.) I'll be doing another round of burping in the morning, and then driving it around town to really verify everything is okay! Unfortunately, quite a few nuts and bolts were lost in the process 😅 But that's a simple problem to fix in the future! Thank you so much for your video! It gave me the confidence to go ahead and just drop the money and replace the egr. Bonus is it has a 3 year warranty! So if it fails I should get another one :D

[@spyderlogan4992]

Remember to read and complete ALL the Toyota Service Bulletin steps to the very last one. Skip none. Check them off as you go, & initial/date the hardcopy. Done.

[@willieking4306]

It is a great video for how to deal with it. Hope you don't get any trouble from your work.

[@RickDelmonico]

Some parts can be cleaned, just use the correct cleaner. The valve is a moving part, you might want to change. Also easiest to get to. For carbon, extra strength oven cleaner ingredients sodium hydroxide apply, wait 20 minutes, rinse. for sludge and varnish use stating fluid. 4 holes in the intake manifold will clog as well.

[@mikechiodetti4482]

Ya this is the type of video I like to see. You know the type of vehicle cause you work on them. How to diagnose, what to look for, tips and shortcuts along the way, updated new parts AND any different installation changes. Oh ya, that happens too! Software updates and of course the road test and what to expect during the drive. When I worked at the L.A. Dept of Water & Power we had lots of "F" Series Ford Trucks and I learned a lot! Mostly I delt with F150 through F550. So. Keep the diagnostic/repair videos coming! And if you're doing a diagnostic/repair and/or a TSB or a recall on a 2020 non hybrid RAV4, you'll DEFINITELY have my attention! Later this year I plan on doing coolant, transaxle fluid and brake fluid changes. Any tips or cautions on these will be much appreciated!

[@ccrdrevil2]

I was a MDT for Toyota a few years back. I remember servicing prius before the tsb/warranty extension and finding all of the carbon in the intake. It was pretty shocking. I currently have two prius C and they both have pinging on acceleration. I am thinking it might be clogged egr issues. Its not misfiring and no dtc, but I am thinking it is early symptoms of it. Guess I got some wrenching to do!

Does using intake valve cleaners in you gas tank prevent intake clogging?

[@donniev8181]

This is definitely one of my favorite channels, I just got a 24' Camry SE and I love the car. I'm curious if I should change the EGR valve & cooler along with the antifreeze every 50-60k miles? Just make it part of the maintenance routine? Thank you!

[@ZachMeissner]

Thanks for this awesome walkthrough! I came across another way to diagnose the EGR system - simply disconnect the electrical connector that's on the EGR valve rather than block the flow. It will throw a code and the check engine light will come on, but if the juddering/hesitation with the engine stops - like your physical paint scraper method - then you know it's the EGR. Any reason not to do it that way so you don't have to take it apart? Thanks!

[@kenweston7604]

Thanks Zack. That does sound a lot easier. I wish the Car Care Nut had replied to give his thoughts on this. Could you reply with the web address (or link to another KZbin video) that you came across that discusses the alternative 'trick' you describe to diagnose the problem? Also, did the check engine light go back off after you re-connected the electrical connector to the EGR valve, or does that have to be reset in some other way?

[@ZachMeissner]

@@kenweston7604 Thanks Ken. It was on the Prius Chat forum if I recall, I'm not sure of the exact link. If you do some searching you should be able to find it. The check engine light did not go off after I reconnected it, I had to clear the codes with my ODB reader. But they did clear.

[@davehumphries2337]

Like the trick using tape n socket to hold nut. Nice to see repair from diagnostic to software upgrade. Clear and understandable & why to replace instead of trying to clean. What it fixed right the first time. Cheers 🇨🇦😎👍

[@Potato0t2]

Thanks for this. I have a 2010 Prius as well so I've been loosely following the EGR saga (mostly on PriusChat), but I barely drive (~90,000 km in 11 years) so it hasn't been an issue yet. For the EGR cooler, would have loved if you could have taken it out (probably too late for this car, but you may get another opportunity) to give us a closer look. My understanding (again, from the PriusChat threads) is that part of the concern and the focus on cleaning it is not just that the cooler is "dirty", but that it carbons up so much that it impedes the airflow.

[@TheCarCareNut]

Hi john! You can actually see when it’s carboned up. It does impede flow when it’s carboned up but when it’s now you still can’t see straight through it. Best way is to shine a light through and see if you can see some of the reflection through it

[@Potato0t2]

@@TheCarCareNut Thanks! I know you don't have any shortage of video ideas, but an overview of what to do (i.e. preventative maintenance) to keep these Gen3 Priuses on the road forever might be one. From what I've gathered so far, it's basically the suggested severe service schedule, plus cleaning the hybrid battery fan intake (or for the 2010, also getting the updated filter screen to keep the fan clean, thanks for that other video on those!) regularly, plus every ~125,000km/80,000 mi go in and clean/replace the EGR valve, cooler, and intake manifold. I've seen theories that this carboning up of the EGR/intake system is what later leads to the head gasket failures, and this should help keep the cars running for the half a million km that the Gen2s would get out of their engines. Is that the case, or is there still a risk of doing all this and still losing the engine prematurely, or is there anything else that wasn't in the original service schedule to add? Thanks again!

Hi AMD, What is the best way to keep the engine bay for any Toyota hybrid vehicle clean ? Can it be steam washed or power washed?

I use: Superdegreaser from Meguiar's, a detailing brush and a power washer. Keep high pressure water away from sensitive areas, eg. master cylinder, high voltage wiring, inverter, etc.

[@k.b.8912]

Removed the intake manifold, the egr valve and egr cooler on my 2013 Prius the other day .. cooler was all plugged up and the valve had fairly heavy carbon built up around it. Had been occasionally idling rougher, consuming oil and lost fuel economy. If you are going to clean one of these coolers, I’ll forewarn you its a PITA, several hours with numerous cleaners/solvents and a stiff wire repeatedly working it through each of the 65 long narrow passages between flushing it out repeatedly 🙄. Luckily I already had the wiper cowl/frame assembly removed from having just replaced the ABS actuator and accumulator system … 🤔 maybe not so lucky 😆. I had to purchase a fancy bidirectional scanner with special functions to bleed the brake system afterwards but saved quite a bit of dough doing it all myself and wound up with a fun new toy thats needed for working on more modern vehicles. Anyway brakes work great again and the fuel economy is back! Also changed the plugs that where coated white, not sure if true but had heard that a plugged EGR will cause a lean condition making the engine run hot and I’d imagine do other damage over time … heard it also creates more negative manifold pressure that pulls oil into the intake through the PCV, did find oil in the manifold and the pcv line .. fehw .. need to change the oil so I don’t wind up with the infamous carboned up oil control ring issue on this car. Car has been some work but if I can keep the fuel economy over 50 without too much service I can’t complain.

[@firebir11]

Not to mention if they pay you labor to try and clean an EGR valve and intake manifold you may as well replace them and be done with it. You won’t have to wonder if it works right.

Hi! Yes that’s one of the things that accelerate it

[@tuffytoys9707]

One of the best informative videos on the EGR system I have seen. I do however have a question, what if you did not want to spend the money on the replacement parts but instead just clean the EGR and in particular the intake where the air gets clogged and causes the shaking at idle etc. What is the best method that you have tried thus far to get the intake clean? If you can make a video about this it would help out a lot of people with EGR carbon issues especially with older model cars and not only Toyotas.

[@TheCarCareNut]

Hi! From my experience cleaning the intake is very time consuming and is not guaranteed to work.

[@ToolsOutsideTheBox]

It would have been helpful to list or link the EGR TSBs for the hybrids. You pretty much described the shake my ‘12 XLE hybrid gets around 40mph. Now I’m mad at Lithia because they told me there’s no recalls or TSBs for my car.

Hello, I watched many of your tutorial videos, this particular one is the most useful for me, I did the EGR cooler, EGR valve, PCV and the intake manifold upgrade on the 7/4 before this video uploaded, everything put back accordingly and run smooth and strong. My 2011 Prius currently passing 210k+ miles and never had the shake and misfire problem, I don't have oil consumption either, instead of cleaning I changed to new parts, all of the parts I order from McGeorge Toyota are the supersede parts. Now...I have a question after I watched this video and you mention that the ECM need to updated to new software, my Prius running fine and better do I need to update the software, I have the Techstream installed in my laptop can I do the software update myself, if soo...please show me where to get the correct patch file so that I can do the update at home myself.
