If you have noticed that your engine is weak, your vehicle won't accelerate well, it stalls out, or it has entered limp mode (the engine cuts off at low RPM), and a check engine code P2135, you have a problem with your throttle body position sensors. Unfortunately, you will have trouble driving your vehicle until the problem is resolved and the code is cleared. Watch this video to find out how you can diagnose the problem, and why the code comes up.

In my case, the scan tool gave me 17 codes relating to the TPS, the accelerator sensors, etc. so I knew the problem was not in the throttle body. After checking the wiring harnesses again, I found out a rodent had chewed on two wires going to the control module next to the brake cylinder. It was hard to see but that was it. Fixing those two wires saved me a ton of money.
Thanks for your great videos. MY Trusty suburban did this last night but it was dark so i checked the codes before coming in. P120 p220 and more.... car had been sitting for a day. This morning a cute ground squirrel was watching me open the hood. Three of the wires were still connected.
I finally understand that darned code that cost me a ton of money just to figure out the real problem had to replace the throttle body which in all honesty I thought the mechanic just seen me as another dollar makes me feel better to know he really was taking care of me.
Thanks A1 ! Very informative and as always great job!
Thanks for the knowledge my friend
What scan tool did you use in this video? Thanks
About code P2185 code and the 6.7 going into reduced engine power mode. Any suggestions please? Thanks!
Question, i have colorado 2.8l duramax, with 46k, when im driving it make pulls when the RPM is going up recommendations or things to consider i never clean any sensors or throttle body i bought with 42k miles
I changed the whole pedal and the problem solved !!
Never knew there is high and low dielectric grease. I have crc dielectric grease in a red dispenser. Just ordered rotor and brake pad kit for a 1995 Honda odyssey from a1 very satisfied great price and quality.
So which type goes on this harness?? High or low?
You gained a new subscriber comrade
Great job
Thank you so much
Congratulations on 1 million!!! 😀😀🎊🎉
+shivam kamaansing Thank you very much!!
Thank you so much! I had the engine light come on and I had it checked it said that code and I'm replacing the Throttle position sensor! I hope it hope my Ford run better and save on gas! It's getting out of control!
Mine just popped on how long were u able to drive until u got it fixed ?
Hi. I've got a 2003 Montero Limited 3.8L. Twice so far (1,000 miles apart) mine has gone into a condition where it will not accelerate. It idles and starts fine, but will not go over 40mph on level road, and takes a long time to get to that speed (severel minutes). It will be fine one moment and then begin this malfunction in the middle of driving it, in town or on interstate. I do have a TPS sensor code (P2135) but also cam and crankshaft sensors codes. The timing system is fine and it doesn't jerk or do anything strange except refuse to accelerate. I can turn it off and after 20 minutes it will operate fine again. Is the the TPS sensor getting hot and then it fails?
What about when experiencing Engine power is reduced, Service traction control and service stabilitrak in a 2011 chevy Silverado 1500 truck?
I have the same year truck and I’ve been having the same issue, you commented 5 months ago, have you ever found a solution???
Same issue here. Did replacing thr throttle body fix your problem???
Having the same issue with a 2004 gmc yukon xl 1500
Try unplugging the negative terminal and plug it back with in 1 min
Same problem on 2012 chevy cruze and no one cant find the problem
Low tech "wiggle" test is a great beginning. Was often thinking of taking off the throttle plate but with mention of laser, glad I didn't. Never occurred to me that there was low voltage dielectric grease meant for computers. There is a warning about moving the throttle plate, manually when its operated by computer control.
+Tom OConnor Thanks for the feedback!
Great Content 💪🏾💪🏾💪🏾💪🏾👍👍👍
Which scan tool do I need?
My 2004 Chevy silberado is having some issues lol
Hello. When replacing the throttlebody. Does it have to go through a relearn process or can you just take the old one off put a new one on plug everything in and you should be ready to go? Thanks. I have a Loss Of Power Light on in my 2004 Envoy. Thanks.
+James Barlow Jr. Thanks for watching! Some vehicles will require a relearn process, while others will be plug and play.
What else causes Reduced Power mode? Bad ground? Accelerator pedal not communicating from the cab?
Sometimes it doesn't always seem to be the throttle body. ot could be throttle pedal, or secondary air injection
I have po1518
Reduced engine power did not have this problem till I had my rear main seal fixed could it be a wire or is it really my throttle
I just thought I would add input as to what fixed my vehicle because it kept sending my throttle body and gas pedal sensor codes ... turned out the oil was low and the place I got it from didn't check fluids apparently so I was able to save a few thousand bucks on a good vehicle. Hope this helps someone who is having random trouble
Have you issued any problems after changing oil? My error came on today with the message "check oil level" along with p2135 thank you
I have a 2008 chevy colorado 2.9L engine and I'm have issues when my truck reaches to temperature when goes alittle bit above the temperature my truck attempts to try to turn off and sometimes it does actually turns off on me can I can't figure it out I already replaced my thermostat and my temperature sensor too and it still does it trys to turn off on me once it turned off on me when I was on the freeway and I was rolling down the freeway on the center lane and I immediately shift it into neutral and panicked and immediately switching lanes to get off the freeway to get on the side of the freeway out of traffic
I change all sensors on my 2004 Chevy tahoe and o2 sensor also an my truck stop a bit but now still does it ? I’m bout almost done with that thing
What code readers do you use in these videos?
I have an 01 olds bravada that when i push the pedal to the floor it has a flat idle and will not shift, but when i let off a little bit it'll catch and shift gears.
Thanks!
Hi I have a 2008 GMC sierra Dinali I recently noticed that my oil pressure sensor readings zero so I went to replace the sensor and and digging through that screen and there was no screen the pick fall right in the hole ,how can I retrieve it back I took off the oil pan still there’s no sign of the pick what should I do?
Thanks for the info...
+Mahmoud Al Shawi Thanks for checking us out! 1AAuto.com
Actually GM has a service update for this code, so it should be a free fix. They told me it was intermittent & my computer, so I just ordered a new one as well as a new throttle body just in case. Still cheaper than what the dealership wanted for just the computer.
thenk you for you exponetion
Great video , question for you my acadia gmc goes into limp mode and stalls sometimes, ive replaced trottel body , mass air flow sensor., acceleration pedal sensor. Pcv, coolnt temp sensor. Thermostat, torque converter rebuilt. Oil and filter chaned. Spark plugs new. New crank sensor, good fuel pressure, still problem not solved any advice?
i am having the same problem, did you figure it out? 2016 sierra 1500
Love your great video’s...... very informative...... thanks
+dave C Thank you! We love empowering our customers and showing how to perform DIY auto repairs with our high-quality auto parts. 1AAuto.com
What if I get no code . And I have also changed the throttle body to a Jet throttle body and still stalls while shifting into 2nd and third.. ?
I’m my case my I had 08 gmc Sierra that my dad had handed me down because he wouldn’t use it before he had gave it to me he changed the trans filter and fluid before it was smooth ran great shifted good after he did it it was like it was stuck in 3rd causing me to take off slow I got tired of it been so I took the filter out put another and found out a cable wasn’t connected from when he had did it he forgot so that can be a problem if u have a used truck or just a thought I was looking forever what the problem was I even scanned it nothing popped up
what scan tool are you using?
Wanted to share my fix, Hopefully it will help someone! Had codes p0120 and p2135 simultaneously, I replace the O2 sensors, throttle body, vacuum hoses, MAF, plugs, pcv and the engine has only 8000 miles on a reman engine... still in Limp mode and pissing me off pretty bad! there was no way it could be any parts at this point so i started checking electrical and found nothing, So i bought another throttle control switch only this time and it came with a new connector(plug)went to put the new plug on and as i was splicing one by one low and behold, the grey wire basically fell out of the old connector(plug) hanging on by merely the insulation, put it back together and immediately out of limp mode, no codes and purrs like the B*^&ch it is!! probably 4-5 months every weekend trying new things. Check your wires!!!!
Mine goes into or can go into engine power reduced even without the engine running with just the key turned on any help would be appreciated please ! I've been dealing with this issue for some time and now my truck just sits here waiting for death.
I replaced the manifold and throttle body on my 5.3 to a 6.2 manifold and c7 95mm throttle body after replacing I got a check engine light on and engine power loss on my dash replaced all the old parts back on. Still have the same problem
what scanner are you using?

Hey 1A auto can you do a video for a 89-98 Chevy Silverado/ GMC Sierra driver side blend door actuator? My clips that move and change where the air comes from have came off.. please help
+Dakota Edens We do not have a video for this repair right now, but we'll keep this request in mind for a future video! 1AAuto.com
My 08 Silverado has a bad misfire and idle problem with a loud noise while running. Feels like it wants to die and when I press gas to go it jerks real bad.
Did you ever find the answer I’m expierncing the same

What is the name of the scan tool you are using?
Could you do a video about “limp mode” please. I have a 2006 Chrysler 300 that keeps limping and mechanics and dealerships just want to charge big money to guess!!! Already spent over $1,400 and it’s not fixed 🤬 just ordered a new PCM and hope it fixes it, but this is ridiculous 🥺
+Martin Prince777 We do not have a video for this repair right now, but we'll keep this request in mind for a future video! 1AAuto.com
Good video! Where can I buy that scan tool? I need a good one like what you are using.
+phillips4 Energy We no longer carry that scan tool. Thanks for checking us out! 1AAuto.com
Should be able to read everything here with a Bluedriver. $100 on Amazon.
@@1AAuto Thanks!! Do you recommend one ?
Good
What is the brand and part number of the scanner
Hello what’s the rough cost on this project
So my Chevy Malibu has an engine reduced problem…. How can I fix it? New throttle body?
I have a 2014 cadillac escalade that keeps kicking reduced engine power and traction control lights come on
My vehicle is saying power reduced what can be the problem when the power reduced come on the engine shuts off then I wait about 10 or 15 minutes it cranks up and the engine light goes off
I can be driving at a steady highway speed for 45 minutes and it will suddenly happen. So I have to pull over and shut it down for one to two minutes. Then it will start and run fine for a few more days.
What scantool is that?
Vri good
What is the model of that scan tool you used.
+Jose Nazario Thanks for watching! We do not offer the scan tool shown in the video at this time, and we do not have the model number available. There are many retailers that sell this type of scanner, so you should be able to find something similar fairly easily!
It solved my issue Chevy sonic
I got a 2006 Saturn ion does same thing check engine light blinks when it want Take gas then when it does take gas check engine light don't blink
What tape of what dielectric grease do you need?
+chad bealer Thanks for watching! Standard dielectric grease is what you need for this job.
how about if I have no code but symptoms only
I have this code I just got a new head and timing chain it was parked for about 4months before everything was replaced my mechanic told me to drive it for a while that it’s just a bit dirty and it will go away once I use it a bit longer ? Anyone know if that’s true?
I changed my throttle body already and I'm still having a reduced engine power problem
Hi guys ! Thank you so much for the videos you guys are life savers! I want to know what is that type of scanner you used so I can order one for me please

My GMC Acadia just get the code of reduced engine power and the temperature went up and also say A/C off🤷🏻♀️
How much does it cost to fix it?
Just had this problem in my 03 Silverado. It seems to happen from time to time.
Can this cause no spark?
What if engine power reduced comes on when it rains or if I wash it.

Is this a major problem?
My 2021 chevy Silverado just shut down and wouldn’t start on Christmas morning
The dash says engine reduce to half power. Had it towed back to where I bought it.
Dealership says it’s the computer that’s crazy to me for a truck with under 2000 miles on it to have this issue already
Just got the check engine light and reduced engine power message today ima take it in this monday 2022 equinox 8k miles
Just happened to me.. but my gas cap was open lol. I closed it and problem solved lllol
Throttle body's seem to be sensitive
My 2010 Silverado is doing this code P2135…. I ordered a throttle body, I will let you know if this fixed mine…..
How is your truck doing now?
Do a throttle body relearn disconnect the battery then try it.
😢 I had that problem with my mercury mountaineer. And I switched the throttle body and instantly the check engine light goes off and the car start running nice n smooth again. But after 2 weeks I changed the throttle body check engine light goes on again. And it throw me the same code saying my sensor a/b again 😢
I have that same problem now. What did you end up doing? Put a tps in yesterday. Now pedal position code comes up.
Entendí más omenos y no puedo escribir en inglés pero la necesidad male millones
Code is p1791 Chevy equinox 2005

I dont think a bad gas cap is going to be the problem
How long can I drive until get it fixed ? It just popped up on my dashboard saying engine power reduced smh
Did u get it fixed i just got that on my 2022 equinox 8k miles 5 months driven
How did you fix the problem?
So what’s next for me?? Replaced the tps
The pcm and cleaned the throttle body. Still reduced power🤬🤬🤬
💪💪💪🔥🖖🏼
What’s the same and part number ?
+Grayson Fisher Thanks for watching. Buy the part in this video on 1AAuto.com: 1aau.to/m/Shop-1AAuto-c
I replaced the sensor but now it idles extremely high. 2500 rpm.
Who's all here for 2017 malibu 💯
Check your oil, when it gets low it goes into limp mode and forces your car to not accelerate well through the sensors that control acceleration
En castellano
It is not a good idea to clean all throttle bodies especially if it will require a program to relearn the throttle body after cleaning such as with a 2011 Silverado. Lol
I hate drive by wire old school cable waygo
I bought a new throttle and it still gives me the code what can I do to fix it ?????
