What you should do if your vehicle goes into engine power reduced mode and what you might be able to do to fix it

[@thunderstruck5484]

Wow that was alot of great insight and inside information along with a how to fix the problem information, thanks Pete for another quality video

[@PetesGarage]

I'm happy you enjoyed it, thank you

[@turnipsucks6416]

This is why I enjoy the channel Pete. You teach, explain and share the knowledge!.. Thank you.

[@PetesGarage]

Thanks my friend... I try to keep it interesting

[@Tchee2]

I am soooo so grateful and excited that I found this video! Thank you guys so much. As a woman, I feel very when I find repairs that I can do myself. I already have all the tools needed in my box. If it wasn't dark outside, I would be ON IT! I can't wait to fix my Stormy Weather tomorrow! Thank you again!! 💪🏾💖🙌🏽

[@PetesGarage]

You can do it

[@robertfulvio5723]

Pete, you are great! I enjoy your channel very much, even though I will never build an engine. I am just someone who developed an interest in cars late in life. You said that you were an engineer at GM for "many, many years." You are not old enough to have LIVED for many, many years, let alone worked that long, my friend!

[@PetesGarage]

Thanks Robert, I am old enough to have been working for 30 years. I guess it all depends on how you define many, many...lol

[@absolute357]

My encore ran hot, this came on. Ive had the head resurfaced and performed the repair. The message wont go away.

[@Charles_S.]

Thanks Pete for giving us the back story on issues like this. Always enjoy your vids👍. By the way is there a way to do an Ohm check on the pedal along it's travel to double check the problem?

[@PetesGarage]

Thanks Charles, sure you could check it

[@HowardGoldman]

Great forensics.

[@PetesGarage]

Thanks Howard, that means a lot coming from a man of your caliber

when the alignment sensors are already on the car and the before alignment specs are recorded I can do a 4 wheel alignment on a honda accord in 10 minutes its totally easy. the hardest part is getting the readings in the first place. if the alignment is off be 4 degrees it can be like driving on ice on wet roads

[@carloszuniga9803]

Thank you so much for the video. I got the p2138 code at the auto part store, and just installed the new pedal. Like you said, there was yellow crayon all over the world lol. Let's hope for the best! Thank you so much!

[@PetesGarage]

They put the crayon on there as a quality check, but it means they have bad processes

[@vivianrodriguez9561]

I just bought a 2017 Malibu 2 weeks ago and as I was driving the message came up I was so spooked scared I had 2 of my kids with me as I was only driving at 30 mph almost cried no joke I was about 5 minutes from home got there turned off the engine waited about 15 seconds turned it on again it was still there looked it up like crazy after seeing this video I was curios looked and I saw the same blue mark 😮 I was like omg now I have to buy a new one

[@PetesGarage]

It can be scary

P21 35 on my 2000 LT Tahoe 5.3 with traction control

[@turbochargedsonic]

I have a 2013 sonic 1.4 turbo and I was driving my car all of a sudden got louder so I tried to get home then the engine power reduce light came on and my car went to 5mph then it cut off and I tried to turn it back on and no response so months later I took it to a shop they replaced the body control module and the car worked great for 3 days and it went back to the same issue so I took it back and they couldn’t find the issue , so far I replaced the starter , ignition switch , battery and still no solution so the shop installed a button to start the car which it’s wired to the starter so when the car don’t start from the key I have to hold the button to start so I drove it back home the engine reduce came back on again and I just left it parked and I still can’t figure it out

[@PetesGarage]

That's a crazy problem

[@bluehxe0000]

i hit this road that slants upwards going like 55-60 and the service traction control, engine power reduced, & service stabilitrak came on along with the traction and engine light. just happened 1 hour ago a need help🤦🏾‍♂️

[@PetesGarage]

That could be many things. Unfortunately it will require some troubleshooting

[@illvangija]

Hello Pete I’ve been having this problem with my 2014 Buick enclave I got it diagnosed n says replace ignition relay which I did n ban it still happened again but that is the only thing that comes up when being diagnosed what could be the problem?

[@PetesGarage]

Electrical problems usually lead to other ones. Something is causing the relay to fail

[@illvangija]

@@PetesGarage ok thank you I’ll check on that

[@user-vx5kb8cc1v]

I have a 2017 chevy malibu 2017 ls 1.5 turbo I've been dealing with the engine power reduced changed turbo... pc valves...and throttlebody... so I came across this video cause I don't know what to do if I pull over 10 seconds shit off I'm good but if I punch on the gas it goes so much then kicks me into engine power reduced help lol

[@tripple3239]

I’ve been looking at getting a Chevy Malibu been doing a lot of research on it. If you didn’t already get a new Accelerator Pedal….. it might be High Pressure Fuel Pump roller follower pin walking contacting the cylinder head that and will put the car in reduce power mode its was a problem with the 2016-2019 1.5 engines You can look online GM posted about it ‘ PIP5610 maybe that might help you

[@tripple3239]

And you can’t really find anything on KZbin or google talking about that issue with the pin hitting the cylinder head so I guess it’s doesn’t happen a lot but I hope you can figure it out and it’s not that problem ..

[@PetesGarage]

Interesting

[@xProMvZ.]

2014 Camaro engine power reduced it’s just cranking exhaust was bubbly noisy little louder then I hit gas hoping it would jump out and boom all electric is on but car is off going down street luckily I parked at house

[@PetesGarage]

That doesn't sound good

[@xProMvZ.]

@@PetesGarage still won’t start I just hit over 100k miles . Just cranks but all power still works. It also says engine power reduced still

[@xProMvZ.]

@@PetesGarage I’ve already replaced alternator and battery idk

[@carlobert8076]

I would test something because EFI wasn't surrent time but they was using diesel fuel at the time General motor timed up with ? Detroit motors they came out with diesel engine my request is carburetor intake on the duramax just ????? It has to done a internal combustion but my ideal can be done and it already has because Cummins, Detroit, international, Ford, has already ran the carburetors on diesel engines, EFI didn't come out at a surrent time specially for chevy early 90s late 80s they swap to EFI. ?

[@jjyy46]

My 10 chevy avalanche did this and like u said oil was low

[@PetesGarage]

It's scary when it happens

[@ccierralou]

Is this common with people thinking it’s a throttle body issue I had this issue but nothing changed when I got that in and added a new crankshaft sensor and a cam shaft and two timing chain sensors 😂 everyone I know that works on cars are saying timing chain but I’m not sure… and ideas perhaps

[@PetesGarage]

It can be many things

[@thatsallfolks3115]

I have been dealing with this problem for 2 years , every time I change the whole throttle body and it will last about 6 months before it says reduce engine power. Luckily my auto parts store allows me to exchange the throttle body for free. I have no idea what to do next.

Awesome. Got to work this morning in my 2022 Tahoe RST 3.0 Duramax and it entered limp mode with check engine light.. Followed advice in this video and turned vehicle off, opened the door, and pumped the accelerator for about 30seconds. Turned vehicle on and both limp mode and engine light is gone.
