Dude for real. Thank you! It’s been two weeks of different answers. Finally someone knows something

You’re a life saver man, had the same problem did all this step by step last weekend No problems since.

Glad I found this video friends....my 2008 Silverado was parked for 3 months and after I picked it up to Thank you drive 600 miles it started in the first 100 miles and did it the whole way. I couldn't even pass someone going 40mph in a 70 mph zone.Thank you braaap 509...nice production.

Great vid... I just had the same thing happen to my 09' malibu, 2 days before Xmas lol... thankfully, we have a friend that had a shop for about 35 years before contracting MS. But he's still able to do certain repairs for us very inexpensively. I'm almost sure that's what's up with my malibu. For weeks it has been running slightly over 1k rpm while idling at times, more often than not, for almost 2 months until today, 12/23/22, when the "reduced engine power" msg came up and wouldn't go over 20mph! Thanks again for the posting and making these vids, you're a big help. The best of the Season to you and may you have a Happy and Prosperous New Year! 🙏✌️

You saved my day! I am writing you 5 minutes after trying this fix. I'm right now in the middle of a 14 hour road trip across country and my 2018 Chevy express started acting up (thankfully I was at a stop light when it happened). I went to a mechanic and he told me what was wrong, but the shop was closed and I would have to wait 2-3 days for the part to come in. So I went to the auto parts store down the street and bought the part $162 after tax. The throttle body comes as one piece with the throttle body sensor. It took me an hour to replace it, but I did and now I'm on the road again!

I had this problem with my truck today, and when I got home from work I bought the sensor and replaced it. Now it's working perfect. Thank you for taking the time to make this video. It helped me a lot.

Thank you so much man. Saved me lots of $ too. Horrible to be on the Memphis 500 at rush hour and the "Triangle of death" was a perfect description! For only 150 more, it was really easy to change with only 2 bolts an d 2 screws. resnap the wires and 45 min later rollin. Peace and love brah. Hope to see you on the other side :)

I had a 07 Yukon that did this when it rained! And noone knew what it was. I had my throttle body changed and no change... I finally had enough and turned the truck back in and just paid cash for an 07 Suburban been having it for almost 3 yrs now and it runs like a champ

I have a 2004 Chev Z71, 4.3l. I have had this Intermittent "Limp Mode" for a few weeks now. Driving me crazy. Had it in 2 shops and no fixes. The problem went away for a few days after the last shop had it. Said it was a loose connection from behind my accelerator. Clearly that was a incorrect diagnosis. I will try to replace this sensor myself, I can't throw much more money at this GM POS... never buy another one. Appreciate the video my dude, was a huge help. Thanks.

I have a 09 Colorado and this literally just happen to me on the highway going about 65 during very thick traffic in construction (of course) lost power, said same message, I had to awkwardly veer over through traffic while my truck was losing all speed and rocking roughly and thankfully I came to an overpass bridge spot. Shut of off once, did nothing. Started and turned off one more time and waited about 10 min longer and it went away as if never happened. Finished my drive to point B - I am very weary of it happening again and this is crazy. Absolutely nuts. As I was sitting there is Park or gear it was aggressively shaking and idoling crazy and it was not a pretty sight. All theee damn sensors are too much man. It’s out of control ! Done with Chevys after a certain year and skeptical of anything “new” to be honest. What a mess. Thanks for the vid and I’ll prob start here. This can not continue while I’m crushing along the highway lol threw me way off. I’m a great driver and I love to drive. Always have so I did not panic but what a headache

Thanks for the video. My truck was showing same code and had rattling noise from the sensor area. Pulled it off and got a new one from Auto Zone $51. Runs even better after cleaning throttle body.

It just happened to me last night, I changed the throttle body positioning sensor and it started to work perfectly fine! Glad I stumbled across this video! Big thanks once again!

Thank you so much for uploading this video for us to troubleshoot the rough idle issue.

That was me on the side of the road....where you filming that? WTF!! So frustrating! Thanks for posting this. I paid to have a new evaporators can. Waste of money. This is the fix! thanks for posting!!!

Gonna have to try this on my 2012 Sierra. It’s been giving me a Check Engine Light, Stabilitrak, and Traction Control light these past 2-3 days. Props for the video my guy

Thanks! It worked for me. Took me less than 2 hours and no more crazy power reduced.

Thank you for the video! I’m going to try this with my 09 GMC and hopefully this will fix my problem

Great video if your trying to save a buck. I know mine did the same thing. 09 GMC Sierra. Took it to AutoZone to put the scanner on it. It reads back, FAULTY WIRES AT THROTTLE BODY. My mechanic told me it would be the throttle body soon as I told em the code it was reading from the scanner. AutoZone sells the whole assembly for 200 or so. Sensor and new throttle body. It's literally removing harness like in the video and 4 bolts you can see in the video right in front of the throttle body. Remove bolts and take off. Clean the inside of intake. Mount the new one and done. MAIN THING MY MECHANIC TOLD ME WAS UNPLUG THE BATTERY BEFORE REMOVING HARNESS. SAID RPM WOULD BE A LITTLE CRAZY FOR 2-3 DAYS IF I DIDN'T. Well I forgot and he was absolutely right. Said the brain was reading a new sensor and would take that long to adjust. Truck is running great now. Took 20 minutes to do everything if you just replace with new.

Thanks for the video! Just fixed my Sierra having the same issues that’s been going on for a few weeks. Saved me a lot of frustration and time

FIXED - My 2011 Suburban LT has had the same problem (engine power is reduced warning, service StabiliTrak and service traction control) periodically and today got much worse. In the past, I could pull over, let the truck sit and I was back on the road. Today that didn't work. I limped home and watched several videos. I found this video to be the most thorough. Took less than 30 minutes. Oreillys sells the TPS for my vehicle for $50.99 - Thanks for sharing your knowledge in this video!! I will post an update only if replacing the TPS and cleaning the Throttle Body Assembly didn't fix my problem.

Thank you so much for this very important information.

Pretty good video. Great instruction. Good visual and explanations were solid. Good stuff. Very good stuff.

This was a great video very informative. Thanks again

9 months later still running great and has not coded 1 time since video. Good luck guys hope this helped

My 2012 2500hd started doing this a couple years ago. Once or twice in the winter then fine all summer. This year it started happening more often till the point where it was happening daily, several times. I tried this fix and it's been good for a couple weeks now. I took the throttle body off to clean it and replace the sensor. Thanks for the advise.

I feel your pain! I just went through this crap, and only have 91000 miles on mine.

Awesome video keep them coming 🇺🇸

Mine is driving me crazy! Thank you!

Thanks for the video I'm getting ready to attempt this on my 2008 Impala the reduced power light came on today

Just happened that to me today I’m following you step by step

This solved my issue Great video Thanks

My 08 Escalade doing this how do i fix the problem it say power reduce to n my peddle go right to the ground

i was stuck in mud and couldnt get out because of damn traction control. took fuse out and it turned off. i was so glad

Mine was the TPS Sensor wire harness clip was partially broken. So when the harness moved - it slightly got unplugged and would set off the "Engine power reduced" message. I got a new one from the Chevy dealer for like $25. I replaced the wire harness. And while I was in there I replaced the TPS Sensor like you did. The truck drives perfect now so far. It's about a year now.

Having this issue with a '15 Chevy Traverse. Going to give this a shot tomorrow. Thanks for putting this video up. Unbelievable that Chevy's new cars do this

Was having the same issue with my 08 yukon. Changed out the tps this morning and lights are gone and running like a champ again.

great job on making this video

Was there a loud pinging sound when all this was happening to truck?

Have same problem with Chevrolet Malibu hopefully works thanks

Good time to clean TB and MAF as well. If you're looking for a scan tool spend a bit more and get one that can access vehicle modules and can do throttle (idle) reset. Usually those can also do steering angle reset, parking brake and a few other resets. I used mine to do TB reset after cleaning.

Thanks this worked for me!

Have a 09 escalade having this problem hope this works for me

Thanks for the video I have 2007 tahoe it shows p0300 code red triangle check engine light it may solve the same problem cleaning the throttle body? Thank you for the answer

This was a great video

Mine came on when pulling my trailer uphill, downhill it goes away? Makes me feel it is a transmission issue?

Thank you for the video I have a 2010 Malibu and same thing is happening

A most excellent video👍 I hope it's helpful for my 2012 gmc acadia. Traction control just buggered on me yesterday afternoon😩 In case I MUST take it to a shop, how much is too much to pay? Thanks👋 Lmao... the orange triangle of death 😂😂😂 That's funny

Mine was doing it, I replaced the sensor, but seems it got worst. Any idea?

I got a 2007 Chevy suburban with the same light on but my lifters are ticking…any ideas?

2007 Yukon Denali with over size tires stablizer strack engine light and tire light on all my unlock and lock buttons go crazy when i turn left going uo and down up and down. Today the vehicle would not kick out of first gear so thankgod i was pulling in at work at foodlion the transmission oil was so low didnt even show on stick worked after that got outta first gear so my neighbor said he checked it a two weeks ago and it was fine so i put transmission fluid in tomarrow going in to gmc for regular oil change UPDate: so I payed 89.00 for diagnostic and its showing low voltage ⚡️ to my battery she said we think u need a new battery which here would cost 269$ or I can get one at auto zone for 209.00 either way I can't get none done right now until next paycheck what do u think I should do next do u think it's really the battery?

My 2009 gmc sierra 5.3l turned out to be the whole throttle body. Not a fun or cheap fix but I tried spark plugs, MAF, MAP sensors and also the TPS and no luck. Turned out to be the throttle body.

sounds nice.

Mine started doing this today and also got the low oil pressure shut engine off message. Did yours do the same?

Wish i would have found your video sooner my 2011 gmc 2500 savana van had this same problemi i have replaced so many things it really is getting old

Mas air flow sensor was my problem, clean it let dry and re install problem solved .

I have a 08 poniac g6 gt and ive changed the throttle body and mass airflow sensor but it still hasnt fixed it.

OK so I'm on the road trying to get home for work from the holiday.. how do I get it to stop myself so I can get home??

Can some one help im going threw it dont know what is the problem i change out alot new things

I bought a throttle body with built in sensor for my 2010 enclave from amazon. Seams like it worked for a month and now light came on again. Could it be a cheap no name rhrottle body i bought? Please help

Good video

I love this video

Have the same problem with my 2011 impala will same thing work

I am sorry i have the same problem with my truck it is a 2013 gmc sierra but mine sometimes turns on the traction control, stability truck, abs, breaks, and reduction of power and when i break ig makes a poping sound and it won't run more than 35 miles

Did you speedometer jump while on the highway

I have the same issue with my Mazda 6..got the MAF sensor replaced and the throttle body cleaned.the problem occurred again after driving for a few miles.Can anyone advise for a solution pls

would have been easier removing the sensor section(unscrew) and work with putting the clips back.

Hi mine says service traction control on dashboard and I changed the sensor

Having the same issue with my Impala man...I had a little piece break off the actual acceleration pedal the other day and out of no where....the car will not accelerate at ALL unless I reset the position sensor before driving every time....but it's also doing the whole reduced power if I sit for.too long...ughh what a mess!

I always thought this was incredibly dangerous, why gmc would design this as a "Fail safe" is beyond me. What if you're on the interstate and it decides to be like fuck you, no power!

Im going with ur step by step tuitoral, ..ill comment yeh or neh for chevy equinox 2.4 LT , with same error lights

THANK YOU!!

I have an 07' chevy tahoe that did the same thing for the last couple of days. The stabilitrak light came on and engine completely lost power, it wouldn't accelerate. Had to pay $400 to have the throttle and the sensor replaced. Praying this will take care of it🙏

My 1500 started doing the same thing was told it was a speed sensor on the transmission or axles. I’ll do this first seems more logical to me

Great. My problem. Had nightmares wondering what next! Any link to part?

Did you have a tire PSI sensor go down? Just curious because I had one sensor go down then a couple months later the traction control light came on but always on for a short while then comes off.

Would that work on my 2007 GMC Yukon I already spent $1000 or more I can’t keep blowing money on mechanics that think they know the problem I haven’t looked at my idle but I’ll clean it and check and dose any body else ever have a p0641 code problem if so please help me out

was the “jolt” pulling you to the left or right kinda hard? bc that’s how mine is, then it goes away. i’m having the same codes with exception of reduced engine power but i can definitely feel it is pushing way less than usual.

Throttle body sensor... change it than it will gain power... sometimes it might be the gas pedal sensor too... best change both

I got a 2008 impala LT.1 year ago I put in a new accelerator pedal sensor and throttle body.about 3 weeks ago i got in and started up one morning and the engine light came on,traction control,reduced speed light came on and stayed on for about a day.the next morning it was off.can anyone give me any advice on why that might have happened.even though those parts on there are only a year old???

I'm having this same problem but in driving a 2011 nissan rogue wld this be about the same fix?

I turned my truck on and it started shaking real bad and dosent even give it gas when I try to press the gas

Do I have to re program my throttle body

i HAVE A 2010 CHEVY EQUINOX. SHOWING ENGINE POWER REDUCED, SERVICE STABILITY TRACK, CODE P0089 AND P228D. HOW DO I SOLVE THIS PROBLEM. I CHANGE THE HIGH PRESSURE FUEL PUMP ON THE ENGINE, THE PROBLEM IS STILL THERE?

Hey very helpful video it seemed to have fix the limp mode problem, however after doing this and starting my truck goes up to 3krpm and stays there until I take it out of park. Any idea as to what is happening?

did it shift hard ?

I’m having this same problem as of right now I have a 2007 GMC Sierra

I did that and I still have the reduce engine power as well as traction control....help

Been in that situation 😔

good video

My truck is doing the same thing and I had put a new tps and it’s doing the same thing. What should I do next? Help?

I have sent three of my guys to do a job to Indiana yesterday and just got the call that this is happening right now. They restarted the truck and it isn't throwing the warning and the truck is running ok. I may have to buy the sensor and have them do the repair on the road. Where did you get the sensor from? A GM dealership?

Hey guys my truck does the same thing, but on mine the accelerator doesn’t work and then after It works. I need help I recently change the transmission on my 08 Silverado 1500 what can I do now ???

Maybe you fix it, if you didn't, i was getting the same problem, the problem was the maf plug, not the maf, i mean all the plug connectors, i just changes and it never happen again

Just wondering if this fixed the problem for you. I'm having similar issues with my 2012 gmc Sierra driving down the road and then a bang and traction control and stabilitrac lights come on with reduced power. Thanks great video.

just went through and replaced the sensor on my 2011 GMC Sierra went to test drive it made it out of the parking lot and it did it again. Kind of at a loss on what I need to do now.

My 08 Yukon XL denali has been doing this... Only my abs and traction control come on with the annoying sign and then goes off and comes back. Last time I drove it for a week like this and then I had loss of power. So I will try this

Man bro do you think this works with a 2009 Tahoe o have the same issues along with the gauges acting crazy and deff no power rpm was up but the truck went no where over 30mph abs light tract light stabilizer light check engine light all on ....good video bro any info would help

i changed mine and it started acting even worse, reving to 3k on its own and same codes popping up as well as reduced eng pwr... any tips?

Having this s issue started this fall been going on now for a few months going to try this this week I’ll let u know how it goes

Same thing with my 07 Escalade the same thing happened to me the last time it happened the motor turned of by it self on the middle of the road so. So yea it’s the orange triangle of death
