2006-2012 Rav4: Throttle Body, Intake, MAF, & Injector Service

[@DoctorCreepy]

I did the 100k tune up plugs wires etc etc and it was still chugging at startup, running like garbage so I decided to try this next. IT WORKED! I cleaned the throttle body out, did about 80mph on I95 for about 3 miles or and now the Rav4 runs great with smooth startup. Thank you very much!!!!

[@josemeza7002]

Please put out more rav4 content...

[@chuckb337]

- If changing spark plugs do it after all this operation, oil also. And wash/ clean the motor area prior. While reving the engine and adding Seafoam, you can turn the key off and carefully add a little raw Seafoam to finish, and the remaining revs/ vacuum will pull it in, coating the insides. Just let it soak the valves, piston head, and chamber a few hours. Better chance the carbon may release/ come loose later. May need a little starter fluid on restart. Good Video. Thx

[@tcwaterdrill]

I just took my 2016 Rav 4 with 35000 miles for its last free oil change at the Toyota dealer where I bought it new and tire rotation and balance on 2/8/21. It is now out of its warranty now. In about 15 minute they come to me and tell me that they have done a free inspection and have looked at and found that my throttle body is all sooted up and the injectors are clogged and need cleaning. I ask how much, it is $220 for one and $115 for the other. So I tell them thanks for letting me know and I would take care of the problem when I get it home myself. They say it will be finished just as soon as they run it through the car wash. Stopped on the way home and got a can of throttle body cleaner and injector cleaner to add to the gas. Got home, popped the hood, removed everything to get to the throttle body on the back side of the engine, could not see where any of it had been removed to inspect it where they could tell it was sooted up. The throttle body was clean as it could be. I put it all back together, put the can of cleaner in my shop unopened and the next time I fill up with gas I will add the bottle of injector cleaner to it. The car engine runs like new so I will write this off to them trying to up sell me their service. This is the reason I do not like taking my cars in because of all the Bull Sht up selling they try to do.

[@Juan-ee2gt]

The first start up took a few cranks. When it finally turned on it looked like it wants to shut off. The lights were dimming.

Wow i cleaned the Throttle body as much as i can but it was soo uncomfortable im a women 5’4 tall..i didnt stick my hand inside the left side of the throttle body i didnt remember that part of the video..also cleaned the air mass flow sensor..i cant believe it what a different!.. the car respond and drive faster, the throttle looks like it was never cleaned before, it was hard for me but IT WORKED !!...the car with 165k miles felt like trash like a 200k some miles but after this it fell like it has a lot of life left..

[@OldCootProductReviews]

For the next generation Rav4 after this, does that lower hose @4:10 pretty much do the same thing and go back to the intake manifold? It's so tight back there to see where the hoses are going. 😂

[@ekitching]

Hey thanks for the video, I never thought of doing those things. I just replaced the alternator and belt on my 2006 Rav 4. Oh man, it wasn't easy. I will try your tune up things next. For some reason, when I start it, the idle is too high. Maybe this will fix it.

[@ddk80]

0:28 there is a rubber hose directly underneath the connector. Do you know the name of the hose or the name of the sensor that was disconnected?

[@AwesomenessIskey]

I never had a problem cleaning electronic throttle bodies except on nissans. Always disconnect the battery before cleaning any electronic throttle body

[@wittsend86]

These Toyota MAF sensors are designed to be removed with the two Philips screws on top. The part you sprayed and cleaned is just the air temp sensor. The actual air flow sensor is concealed and only accessible by removing the sensor from the filter box assy.

[@MasterJacks]

Thanks for the note.

Thanks. Is the liquid from Throttle Body Cleaner going inside the butterfly opening. Is that OK?

[@MasterJacks]

Yes, it's flammable and will be burned by the engine. When you first start the vehicle, the engine will run rough until it clears.

[@s3rg3i]

Thanks for making this video. I have the same color 2006 RAV4, in a 4 cylinder as well. Just performed the throttle body cleaning on it and I think I solved an engine shuddering issue I had (dropping RPM's to 500 right when I slow down to a stop). Just wondering if anyone here has this car? If so, are you experiencing some whirring/humming noises coming from the driveline? Curious to know if you have the steering clunking noise as well? I haven't been able to definitively nail the origin of these problems, wondering if maybe you have... This car has been unstoppable aside from a few non-critical issues. The only downside I can think of is that I don't have the 3.5 V6, those are peppy for being an unassuming crossover.

[@rubiconklbrutorowman7577]

I have those metal clinking sound when I back up or trying to turn to the right or left... Must be related to more than one causes?

[@Marshcreekmini]

I'm getting the shudder also. Only happens while in gear. I also think I should be getting a little better mileage than 18-19 for standard driving. I would think it should be above 20.

[@baron7024]

I've done everything as shown however did not completely eliminate shudder and RPM drop. Was told clunking noise while turning is characteristic of the electric steering. Is whirring noise loudest at floorboard behind driver's seat? Fuel pump is in tank and close to that area. My 07 recently started making a whirring noise and am thinking fuel pump is going. Also concerning the 100,000 miles Iridium plugs. NOT. Check them for yourself. I'm thinking 75,000 miles at the most. Good luck!

Currently have a 2008 rav4 with 182,279 miles on the ODO. And idles super low to 500rpms and shakes hard as hell but goes away. But I’ve noticed that at times it would be related to my AC when I had it blasting and cranked up high. But when I turned it down it would stop shaking. With that said, im going to do exactly what was done In This video and see how it turns out.

[@moses2986]

Update: just did exactly what was done In This video and overall the shaking and low idle pretty much gone. The idle sits just at 1000rpms even when ac on, but still shakes a little when blasting. On top of this, I did this whole service just before I took it on a 6hour drive down to a border town to see my great grandparents. And drive it an additional 6 hours back. Still runs great! So yeah recommend doing this. My odometer sitting on 183,267 currently.

[@kazshamael]

I didn't know you could use the intake manifold port to clean past the throttle body with Sea Foam!! I've been buying the Sea Foam Top Engine cleaner with the little straw attachment. Such a pain to use because of the throttle body location which forces me to turn the bottle upside down and just makes a mess. Your way is so much easier!

[@MusicIsBestDrug]

You did a better job than the video by dispensing the Sea Foam Top Engine cleaner over Throttle Body. Why? Coz this enigne is a Direct Injection engine. It means the fuel does NOT flow over the intake valve. If it had to, it would keep the valve clean since Gasoline is excellent solvent! Intake valve being dirty and gunky with oil that comes back from PCV valve is what causes major engine problems. That seafoam in the tank is NOT going to clean your intake valve. It will only clean fuel injectors at max. The actual complete maintenance needs Fuel Injector cleaner (in this video) PLUS Sea Foam Top Engine cleaner which will indeed go over the intake valve (coz you are mixing it with air, which does go over intake valve). What you did, was a good job. You cleaned the intake valves as well (which are more important than cleaning fuel injectors)

[@oliverdeegbe]

Can you help me with how to resolve a system too rich?

[@smooveb191]

Hi after doing the throttle body cleaning and adding seafoam in the fuel tank car ran smoother. However after adding the seafoam to the air intake hose as described, during the process, check engine light, VSC, and 4WD, lights came on dashboard. I drove the car for a few miles, and still on. Any insights?

[@MasterJacks]

It's not uncommon when doing this to get a misfire code which can deactivate the stability control. If it's running smooth again, I would clear the codes with a code reader and everything should be back to normal. If you don't have one of those, you could disconnect the battery negative terminal for about 1 min, then reconnect it.

[@jaychadderwala8975]

@@MasterJacks thanks that cleared up the codes. However the car still has a bit if a shudder when stopped at a traffic light. It is more pronounced when I change gears to reverse. I therefore changed the spark plugs too, and no difference. Any other thoughts?

[@MasterJacks]

@@jaychadderwala8975 my guess is that with a clean throttle body your idle rpm is lower. As the throttle gets gummed up, the computer cracks open the plate to maintain airflow, which increases rpm. Now that it's clean, it's idling back down to where it should. At stop light or reverse, there's a little bit of torque converter load on the engine (as apposed to being in park) and it lugs rpm down lower still. I wouldn't be worried about a shutter if this describes your symptoms. If the engines shakes quite a bit, could be you have a worn motor mount(s).

[@RR-ev3po]

you sprayed that MAF cleaner and is dripping down moisturizing the filtering net of the air box. I can fee the awfully -toxic smell of the air blowing in the cabin. Did you think a little before doing that?

Good question, yes. The cabin air intake is separate from the engine air intake. Not only that, the 30 minutes it took to finish the job and reassemble left no residue that hadn't already evaporated. Thanks for watching.

Do you have to disconnect the battery in order to be able to stick your finger inside the throttle plate, I hear you should not move the plate at all, or is it just a myth?

[@MasterJacks]

I can only go off my own experience, but I've never had a problem manually opening an electronic throttle body. I've always done it with the key off, but haven't necessarily disconnected the battery. Once you turn on the key, it might mess things up a bit if the computer is commanding one thing and you're forcing something else.

Mahinda Ranasinghe that's a little outside the scope of this video. I would recommend watching some videos by OTC and getting the help of a local mechanic or mechanically inclined friend to help you identify the schrader port on the fuel rail.

[@MC4D.]

Will cleaning the throttle body help with the long cranks when engine is warm? I heard yours crank a bit before starting up after the cleaning

[@RadRob84]

The long crank was because he sprayed throttle body cleaner directly into the engine and it was partially flooded. Best practice is to remove the throttle body from the intake and clean it with a rag. Toyota released a technical service bulletin regarding spray cleaners damaging the electronic motor through the throttle shaft.

[@HueghMungus]

Hello, if someone could reply that'd be great! Wouldn't that cleaning liquid mix with the gasoline/diesel? I am no mechanic so I figured I'd ask before attempting this :)

[@MasterJacks]

Thanks for the question. SeaFoam injector cleaner is a flammable additive for gas or diesel fuels. Adding it to the fuel tank is one of the many ways it can be used.

[@nhatquangtruong8858]

Shit... i just did this and now my rav4 2006 automatic 2.4l is idle really high. It is idling at 1.6 rpm?????

[@MasterJacks]

I'd make sure all vacuum hoses and sensors got plugged back in. If all looks good, try disconnecting/reconnecting the battery, then take it for a drive and see if it normalizes.

[@nhatquangtruong8858]

@@MasterJacks I figured it out. The ECU was used to dirty throttle body. It was running like it was before the cleaning. I unplugged the battery and pulled the fuse. After 20 minutes the ECU reset itself. Everything is working normal now. It just take a like 15 minutes of driving after ECU reset to get it working again.

How many kilometers do you need before cleaning both the Throttle Body, Intake, MAF?

If you did this every 100k, you'd likely be staying ahead of problems.

[@KbutY]

I just had to replace the EVAP valve in my 08 Rav4 and now I'm getting a lot pf shaking while idling. Would this, in theory, help with that issue or would you recommend what you did with the spark plug video? Thanks for any info

[@MasterJacks]

Not sure what the correlation is between the evap repair and the rough idle, but doing this procedure is good maintenance and may fix your problem. Worth a try in my opinion. Spark plugs would likely have given you a check engine light for a cylinder misfire. If it's got 100k miles on it and they haven't been done, it's also good maintenance that may improve drivability..

[@oliverdeegbe]

Thank you for the info. I had a successful servicing of my Throttle Body, Intake MAF

[@Sail1skate1sleep]

Hi Jack, very helpful videos. I have a Rav 4 2006 4 cylinders and recently replaced the alternator, and the drive belt. Note I disconnected the car battery which I believe reset the ECU. After this I noticed the engine was running rough, which got slightly smoother over the last couple of weeks but was still happening when idling. I then replaced all spark plugs which were quite worn. Now the car runs well except when idling the Revs often drop around 500 thus vibrating the car. Would a throttle body, intake, MAF and Injector service help with this? If not what else would you suggest to do? There is no engine warning light or codes displayed on my OBDII

[@MasterJacks]

A dirty throttle plate can cause the symptoms you're are describing. If it were mine, I'd definitely try that first. It's cheap and good maintenance even if doesn't fix the problem. A MAF sensor can also cause erratic idle issues and not necessarily throw a code. I'd try those two things first.

Randy Murray this car didn't have any idle problems, but I have worked on cars throwing codes for high or irratic idle caused by restricted airflow across the throttle plate. I recently serviced a Ford Focus with a code for "RPM out of range" and cleaning the throttle plate solved the problem. Electronically controlled throttle bodies are more susceptible to this fault. I did this particular service as preventative maintenance. Plugs and wires solve a lot of rough idle problems. Hope that helps!

Hi there, great video, car is running much better now. Just one issue I’m having, when I was doing the last part, I did just as you said, had my wife hold the gas at 2500rpm and funneled in just a little bit of sea foam, my check engine, VSC and 4wd light came on and won’t turn off now. Should I be concerned and have it diagnosed? Or should I just try to reset it? Thanks for the help!

[@MasterJacks]

Running the seafoam treatment can cause the engine to run rough during the procedure. If the computer isn't able to successfully compensate for the erratic idle, it will deactivate some stability control systems so as not to create a safety hazard in a system it can't fully control. This also sets a few malfunction indicator lights. If it were mine, I'd clear the code(s) with a scan tool or by disconnecting the battery. From what you've said, that should clear everything up! Let me know how it goes.

[@karkule5919]

So, mass air flow sensor cleaner cannot be used to clean throttle body as well..?

[@MasterJacks]

You can clean the throttle body with MAF cleaner, but not the other way around.

[@LORDRA1DEN]

Why didn't you just unplug the maf and take it out to clean it? It'd save the step of taking the box off and opening it and all that. Also, do you really need to disconnect all that to clean the throttle body? Can't you just disconnect the hose and push it out of the way?

[@MasterJacks]

adam smith Good comments. It sounds like you are pretty meachanically inclined. I would do whatever you feel is easiest. So many people try to "save time" by working around things instead of removing a few components for better access, only to end up with bloody knuckles, broken parts, and much frustration. I'm probably on the other extreme doing a little more than is needful. Hope you found the video informative, even if you recognize a better way of doing things yourself. Thanks for watching.
