I could tell by his demeanor and his non rehearsed, natural flowing dictation that he has been around the block more than a couple times and is at home doing diagnostics. When ya got experience in an arena it shows. In this case he had several pretty good indications of the issue. But as for the reduced power mode, or message, I've had several impalas in my garage, many things will trigger this cars self preservation mode. The Throttle position sensor, the variable valve timing servo, the accelerator pedal position sensor, the oil pressure sensor, any of the engine wiring harness wires are a huge trouble area in these cars and often over looked (my Impala, 2006 has 168 circuits in that harness) These cars build a huge amount of heat in a very congested area and the insulation will get brittle wires get brittle, shorts and breaks are common and hard to run down. Often times even an intermittent problem, hit a bump the break in a wire separates, hit another bump now its fine kind of thing. Advise is be diligent, start with simple things, as you rule them out move up. Remember that often and more for the older cars those trouble codes are suggestions or suspects, (innocent until proven guilty) . A good digital volt ohm meter is a perfect partner for a scan tool. Check, test, and verify a sensor is bad as much as possible before replacing it. I've seen guys spend $1000 by reading a code, oh I'll buy that sensor, then get another code, well I need that one also and so on, only to bring it to me and learn a connection was corroded. Some of these sensors may have a range of 8 tenths of a volt between good or bad. Good luck to anyone with these issues, just go cautious, stay calm, be methodical, and research means everything.

Great comment/info!

[@zdp-189]

what a pain in ass. I changed the gas pedal/pedal position sensor in my moms Impala, and now we're getting these issues in again now, all these electronic add ons hardly give any power or efficiency, just all headaches down the road. I wish I was alive during the all mechanical era of big blocks! Also it seemed like on turns the ABS would kick on and stutter for a second while flashing the traction light for a second also- I believe it may be a wheel speed sensor in the tire assembly? Too many similar dam sensors it can be all joined in 100 feedback loops!

[@heretheregeneralrepair1712]

I've seen impalas with clearly clogged VVT Solonoids throw every code but loss of engine power, even no start conditions. Definitely a fickle creature

[@skydiver1955]

I had this problem with my 2011 Chevy Impala for over 2 years. When it would happen and I had "service stabilitrak" and "Traction control" show up, my temperary solution was to disconnect the battery for about 5 minutes which would reset the computers. This worked for the short term but only short term. Eventually the problem came back. All the videos I viewed indicated frawed wiring and a mechanics help. This video was the only one which made sense so I took a chance and the sensor replacement solved my problem and was something I could do myself without help. I performed this solution 2 months ago and it has worked. I bought the part on ebay saving about half of what retail would have cost. I would highly recommend this sight for solving small vehicle issues. Always do your research before making mechanical repairs on your own

Great learning vid and agains...shot so well.

[@jonathanantons8648]

Thankyou so much!... I was driving my 06 Impala ss and the "service traction control" came on along with the "reduced engine power"... I got it home in limp mode after only being able to go 30mph with a very rough idle... got it in the driveway and starting looking... I noticed when I turned the key to the "on" position I could hear a very loud grinding noise... Turns out the gears inside my throttle body were stripped therefore causing the rough idle and grinding sound. Picked up a new duralast Throttle Body installed it myself in about 15 minutes started the car and acted like nothing even happened in the first place... Came here first to see that the problem mightve been and low an behold... Throttle Body it was... lmao

[@kingkirk9264]

Very informative thanks...I've had this problem...I fixed the throttlebody...the problem came back intermittently, on my 2009 buick lucerne 2009 4.6l cxs, it drove me crazy, this problem can come from a bunch of different problems, including bad ecm, all the way to a bad short or ground, thank God my problem was from a low battery, make sure everyone has as full charged battery, because if the ecm/computer dont have the correct voltage at the time its started it will act the same way...your battery may seem hot as mine was, It even had enough juice to spin the engine with out hesitation, it will fool you, until I checked the voltage before starting and it was at 12.1 volts....if this happens , clear codes, reset the ecm/computer (Google process). Then replace or charge battery as needed (in that order) Before starting again. Hope's this helps anyone who's having similar problems.

[@joecruggle7638]

Thanks for the info

[@mikeoneill7360]

Awesome, I have a 2008 Impala with a 175k, got this code as a pending in the history. Erased the code, never came back, no issues as of yet.

[@lisab3396]

Really fantastic, clear video and audio! Hopefully this will help to future viewers...... The TPS is simply a Variable Resister! To describe it closely is as follows. Consider windshield wipers as an example. As the wipers move back and forth, they will tend to wear down, will start to bind and squeak and leave streaks on the windshield. That is exactly what happens to the TPS contacts as the throttle is constantly opened and closed over time. It just simply wears down the resister on the circuit board and or wiper contact that moves with the throttle plate. As it wears down, it will give inconsistent/intermittent signals to the OBC/ECM. Kinda like drinking beer and smoking pot to some of you as it confuses the Brain/Computer to think one thing when something completely different is going on. Therefore, the body, or in this case, the engine will not respond as programmed! Just a little hint to you DIY mechanics and/or junkies! Cheers

[@johnpali5894]

Very well explained

[@youdontevenknowwhatyoudont7657]

Not to be a now it all but the tps is called a potentiometer. A wiper moves across a voltage resistor as the t.b plate opens and closes. Varying the Volts, not like a rheostat that varies the amps. Usually the constant wear creates dead spots in the tps signal.

Great vid. HOW TO CLEAR REDUCED ENGINE POWER. Tps reset on lots of gm is key on but don't crank the engine in this order. Key on, key off, key on for 5 seconds, key off for 5 seconds, key on for 15 seconds, key off for 15 seconds, key on, key off, start the truck. This will clear reduced engine power and will probably get you to a shop.

[@cowboysbbq3572]

or pull maf wiring harness plug, blow on connector, check pins to make sure they arent bent. put wire harness end back onto maf, and start it up. also, check your pcm ground wire on valve cover bolt,passenger side rear of engine, and check your engine ground strap opposite of the same side, rear of engine.

[@priestmahomes7393]

Thanks, great video. Had P2122 on my 2008 Impala and reduced engine power intermittently. Became a almost daily, so I replaced sensor. No luck, code came back same day. So I tried replacing accelerator pedal and voila, code gone! Knock on wood it lasts... Only been a week so far but it had been coding daily up until I switched the pedal... Hope this helps someone out there! GL

[@joematukonis1801]

Clear and concise instruction. Idle patter helped a little bit, too. However, only good if it's the throttle body and not the accelerator pedal that's the problem. Would the scanned codes differentiate the possible problem sources?

[@trey2048]

Thanks so much for the video. It was only slightly different for my impala ss. Instead of cleaning the throttle body, I just ordered a new one as well as a new gasket. I put it in this morning. Plug and play and so easy thanks to your walk thru video. Saved SOOOOO much money. Thanks again!

[@johnjohn-vd4xu]

I had a 2008 Malibu a few months back; same problem but the "Reduced Engine Power" and sputtering came after 6-8 miles of driving and would go away if you just let it stand for 6 to 8 hours (overnight). I replaced the both of the Variable Timing Solenoids, and another variable timing sensor; Didn't fix the problem. Then after watching a million KZbin fix it videos (because I am not a professional mechanic), I replaced new Battery Terminals, removed and ran without the Thermostat (even though there was no heating problem), and even tested with a direct connection to the Radiator Fan, so the fan will run constantly (again there was no heating problem but a KZbin video suggested that it fixed the problem in their same model Malibu. It Increased the 6 to 8 miles to about 10 miles, but the never can get rid of the Sputtering and the Low Engine Power that will just happen. From all the videos I watched and the comments I have read, this problem can happen in the Malibus for so many reasons. There is NO one fix. Even the Chevy dealership acted like it was JUST MY CAR, when so many people were having the same problem and the fixes weer so different. The dealer wanted $200 plus to diagnose. Some people had issue reoccur after spending Thousands at the Dealership throwing new parts. Just do the research by reading the comments on KZbin videos. Then there were some people who had fixed it by replacing the main fuse box. For some people, it was the traction control that was causing it. I would have let you have it for free if you lived close to Los Angeles. I just junked it and lost about $3500 and a lot of time and effort educating myself, working on it myself etc etc. OMG The aggravation is just not worth it. Just Don't buy a Chevy Malibu or an Impala. Even Hondas and Toyotas have this VVTI but not these kind of issues after 6-8 miles of normal driving. Then you have to drive home at 10 mph and it does not go away even if you start it in 2 hours -- needs to be left alone overnight. It is FUNNY. Chevy made these cars with a lot of sensors and from what I understand even Chevy does NOT know what's wrong when the issue happens because all kinds of problems can display the "Reduced Engine Power" warning and the associated sputtering, like it is running on 2 pistons. I am Just gonna start RUNNING if anyone even gives me one of these cars for free. I have never had a car like that 2008 Malibu.

Those clips are easy to install if done correctly. Hammer not needed. You did install of clips backwards. "L" shape goes on first. Then press the "V" end on. No hammer needed. Beat on those parts can cause damage.

Great job, I have been having to deal with this issue with my 2011 Chevy Camaro SS. I took it to the Chevy dealer and the tech scanned it and told me that I needed my throttle body cleaned but he said that they would tell me to just buy a brand new one so that they could make a dollar off of me so he reset the error code for me. It happened again about three weeks later I let the car sit for a day and came back and started and it went away along with the check engine light. I have to get it done soon so thanks for the very informative video.

Hi there thanks for your video, question the butterfly has to be closed all the way down or can have an small gap?

[@Tomsfoolery.]

It’s normal to have a small gap. Since drive by wire took over, throttle bodies don’t have idle air control motors so the throttle plate does that job. Hence why you’ll see a small gap.

Last fall I was looking at 2019 Tahoe & with trim package I wanted sticker price was close to $74,000. C’mon I would have to save for what seems to be the rest of my life. Chevy has brought back the blazer for 2019 & I do love the price. As for our Chevy’s that are already out there on the road, I suggest finding a certified Chevy mechanic avoiding the dealership...I found my certified GM mechanic at Graham Tire in Grand Island, NE. By the grace of God, an auto parts store employee steered me in his direction. My Bu is running fine now, fingers crossed & knocking on wood.

[@AGCMI_BENIN]

I have a chevy equinox 2010 with reduced power engine and traction control. when scanned, code P0089 and P228D is erasable. Is this method also useful. I bought new high pressure fuel pump, not still working. what do I do?

[@floydgordon3306]

I put a quart of Lucas high mileage oil additive and presto no more p06de code it would come on in about 2miles continuously cross your fingers oh by the way it said low power but I couldn't tell that it had diminished power .I also put a c shaft position sensor on and it helped the running ability some but be careful that bolt will easily break off into the block I would recommend using the original bolt on the sensor . New throttle body did not help . Couldn't get to that oil pressure sensor yet . I intend on shorting a deep well socket to get to it more easily and a flexible half inch drive I believe this will work on 2.5 Chevy Colorado 2016 you have to get that white clip completely off and you can then push off connector with a long screwdriver

Great job buddy............ thx much for teaching us!!!! 👍 👌 👋👋👋👋👋 I got the same prob. with my car. 🙄🤪

[@chetspencer3241]

does a bad gas pedal sensor give the same code?- thank you for the video!

[@adamsaquatics3332]

Yup

[@mikesecondo2254]

[@mikesecondo2254]

No

[@adamsaquatics3332]

@@mikesecondo2254 yes it can. If its completely bad it will display a throttle position sensor code. If if its going out, it absolutely can display the same code

thank you for your contribuition for all the people that have the same issue but to be honest each case is different is no t always the same, let me tell you my experience, l had issue with my differential and i spend a lot of money with 3 difents mechanic that just want to steal my money because one said that was the cv joint other that diffential but, at this time i dont know exactly what was the problem, the point here is that finaly i fixed the diferential problem but the engine power is reduce light sudenly came out and the mechanic thief said that was the throle body, but finaly i found a honest mechanic and was something about the gas sensor, to end this tip to my experience not always is the throttle body think more the two time to move at your throttle body because is really delicated

[@patvadnais9216]

Really enjoyed this video. I replaced the Throttle body with a new one, the car started fine tried to drive it and it started throwing random codes. I can clear them with my reader the car will run fine but they return after sitting. I disconnected the battery cables jumped them together for 10 minutes reconnected them and noticed the radio presets didn't clear, did this sequence 3 times withe the same result. Codes returned each time. Is there something else I should be doing? Thank you for the information.

[@chonarrambide5375]

It worked on my Malibu 2008 thanks allots

[@Tomsfoolery.]

That’s great! Thanks for watching!

[@kevmonel3533]

What worked for your malibu cleaning or the sensor

[@mcdizzle7740]

I have a 2010 equinox that is doing the same thing. I replaced the throttle body which came with a new tps. the thing is , it's still doing the same thing...I've tried doing the manual relearn several times where you start it up and let it idle for three minutes then shut it off for one minute x3...I even left the battery disconnected overnight...still no luck

[@roymariano7116]

Did you have to kick the front passenger tire, just like what the guy did in the other video about this specific issue ?

[@mikesecondo2254]

No...kick the owner of the vehicle!!

[@ahmadalzupi9250]

Hello brother i have a malibu 2013 Today i got the same problem .. the car was fine till this ( check engine with downword arrow + traction cintrl lights went on ) The code on dashboard is code 84 And when i checked it on computer the engineer told me its from the fuel pump i bought a new one but still not solved i hope ur video helps me tomorrow . Appreciate ur help

[@Tomsfoolery.]

Thanks for watching and good luck! Let me know what the fix was, I’m curious.

[@MAGDIEL_ALVAREZ]

Did you ever figure out was it was I been having the same exact problem with my 2013 Malibu Ltz they told me that I had to change my front fuel pump. So I paid Chevy to change the front fuel pump after doing so I picked up the car and it ran fine but after 20 min of running the car would just shut off there is no check engine light on what so ever took it back to Chevy now they are telling me its the Exhaust cam sensor that’s causing the car to shut of wile on red lights I don’t know what to do.... fuck Chevy I will never buy a Chevy ever again

I have a 2003 GMC Yukon Denali has reduced engine power light on the dashboard I replaced the gas pedal sensor throttle body module and the throttle body it's still on what do you recommend? I wonder if my throttle body is a bad part

[@Tomsfoolery.]

Have it scanned and find out what codes it has. They’ll point you in the right direction.

[@Chevyguy05]

I scanned it with my Fixd device and it shows the code p1515

[@kathosey]

my 06 buick rainier had this exact problem and we are going to apply this fix now...fingers crossed....tired of stabilitrack messing with acceleration flashing...waiting to accelerate after the dumb thing quits flashing..which btw has gotten worse over time...will let u know how this hill billy girl does!

[@Tomsfoolery.]

Good luck and post the update!

[@LifeJourneyinternationalChurch]

Does my warrant cover this before I take it the GMC shop?

[@Topshotta1976]

I keep getting the engine reducing power code also. But when I read the code it says throttle position sensor. Circuit E low voltage.

[@elinglesdiario7805]

Very helpful video. Got to go put it in practice now.

[@michaelcook2342]

2013 cruz 1.8 I've changed intake crankshaft, both camshaft sensors, MAF sensor, cleaned throttle body. Now the stability control service is on. How can I find the issue that may or may not be like you're video? Please help tired of buying things I don't need.

[@shelbyspapabear]

That little scan tool you have listed....would you recommend that for someone with 05 pontiac grand prix with reduced engine power issues but they never can pull codes ate auto stores cuz light goes off

[@savage_family1051]

You did a great job

[@martybateman9897]

Hi. Thank you for the great video. I replaced the whole engine throttle body on my son's 2009 impala with an OEM Delco part. It went well, thanks to you! Unfortunately, he is still getting the same engine power reduced notice....any suggestions? Thank you again.

[@grudgeracinmedia]

Do you disconnect the negative terminal

[@musterseeds1778]

this is a nice coaching watches and learn, thank you.

[@RacerIDMedia]

I have the same stabilitrak/traction/reduced engine warnings. we read the code present and it says it is a fuel regulator problem. Any ideas on where and how to change the fuel regulator? Or is this something you have seen and know the culprit? Thank you and sincerely appreciate your videos.

Amazing video thank you it really helped me !

[@Tomsfoolery.]

That's great! Thanks for watching!

[@daeewest]

Hey, I have this problem going on at the moment as well… Do you remember if after fixing the problem it just showed up again causing the same thing or was it a permanent fix?..

[@CraigDAL12]

Can you share a link to purchasing the scanner you have, or let me know what the exact model number/brand is?

[@t.j.6574]

It'll come back on, the issue is the hub assembly connection. Fix that It'll go away. Even though that code came up for that throttle body actuator

[@DubsforLife1993]

Great video man.really appreciate your straight to the point format. should I unplug my negative unit on my battery before i pull my throttle body off ?

[@Tomsfoolery.]

Yes. It’s good practice to always unhook the battery when performing repair.

[@maar5725]

If you want to ; clean electric electronic throttle body in position !!! , all you need , just put ignition switch ON and keep it ON until you finish the cleaning, it will open the throttle plate for you to clean it .
