Thanks for the great video. I'm just getting ready to tackle this problem in a 2006 Buick Terraza and your video was immensely helpful.
Man I love being a Chevy vict.. *caugh owner
Man that's why the car didn't start after installing the throttle body , I forgot to kick it ! Thanks for the very informative video..
Te pasas de verrrde
Was mad about not knowing what was going on with my car and you provided perfect information and the kick to the car really made my day better and I thank you for that😂
I feel like I had this problem years ago with my impala and I also changed the this part and it worked. But forgot all about it and now I have the same problem again, and this helps thanks!
I think you did a good job explaining and visually showing us step by step to fix. You made it more simple to understand. thank you
This has to be the realest repair video on UA-cam to date! Lol shows 100% of the struggle
Thanks for watching! And you are correct. It IS a struggle...
Hello please what do you think is wrong with my 🚗
@@lifeafterlife8417 hi
The dynamite comments made me cry. Love it, and relate. Thanks
I have 330 k miles on 2004 Venture. Uses leaks no oil runs excellent Original motor trans rack. Only changed fuel pump starter alternator well hubs. Very cheap to fix. Excellent GM product. All my other Chevy trucks over 250k no major problems.
I had a great time watching this video, cracks me up, a good kick always help
Thanks a ton for this. I have an 2007 Chevy Uplander and 2 days ago we got the same error. Problem at my auto stores is that the sensor costs almost as much as the whole throttle body. So I just replaced the whole thing based on your video. Thankfully it didn't need reprogramming and worked perfect out of the box. Used Hitachi ETB. Thanks a ton.
EDF Central You're welcome. Thanks for watching!

Just experienced this on my 2017 Chevy Malibu LT.
I have the same thing on my chevron cruz 2013
Excellent video, just did this yesterday for my 06 Monte Carlo outside in 20 degree weather. Super easy repair and resolved my issues.
My 2002 chevy 2500 just gave me this reduced power code and the truck wouldn't go more than 15mph with the throttle to the floor. The truck would always stall on me like it was having the gas shut off. It would do this at low speeds or in idle. It stalled on me today and wouldn't start. Ran the battery dead turning it over. Finally decided to start with a jump but then had the reduced engine power...Thanks for this video!
The crickets in the background is a nice touch.
l got that same light on a 2012 chevy silverado and they couldn’t find the problem or the dealer and but if they found the problem after 3 days it was the computer
🦗🦗🦗🦗
I wish the warning chime was the sound of crickets. Three chirps for engine power reduced would suffice.
Just had this issue in my friends Equinox. You got a sub for the dynamite joke at the beginning. That's the easy fix for most car problems lmao
Edit : Just finished the video. Thanks so much for the crystal clear view and great information.
Mines currently does this all the time for the past year 🥴
So this fixed the equinox?
This video gives new insight into what could be done to repair. Thank you so much
He's a guy who loves his truck. +10:53 A swift kick to the tire..
I'm a single mother of 3 young boys and I absolutely needed this!! Thank you.
You're welcome!
Thanks so much for the help, we didn't know what the issue was so we google the problem, this video popped up, followed your instructions and haven't had a issue since!! 👍👍
So glad it helped! Thanks for watching!
When you change the sensor or the throttle body and sensor will the car turn on or I have to take it to a dealer so they can reprogram it?
@@anonymous-gx8os It will run
Video is a learning experience.
You sound like Tim Conway~The Oldest Man. Awesome video.
I have a Impala LT 2012 having the same issue never worked on this part before but I'm going to learn and do it soon thank you for the video
Pop those clips with a flat blade screw driver. Thanks for posting this. It solved my engine light issue that was making me crazy.
Yes I experience this problem 02/17 and was far from home,what a mess and I was pissed.
Cleaned my out and reduced power was over, thanks for the video
The messag can be displayed because of other reasons as well but ty for this great video of this repair! Very helpful especially to someone such as myself ! !
I changed my throttle body and it fixed mine so far
What vehicle and year?
Despite my frustration with my 2012 chevy impala having this issue, you kept me laughing and I appreciate your humor and info sir!! thank you !!
Just give it a good kick. Not TOO hard, but it helps with the frustration! Thanks, for watching!
My 2012 Impala is a whole dang headache
Great video ..
Is suitable for weak cruze lt engine when ascending.
Thank you I have a 2002 and 2004 Chevy Surburbans and both have done the reduce engine power messages. Both have been great vehicles with the least amount of repairs both have over 250,000 miles a piece, on them. Thank you I now have an idea where to start.
Those are the older models. Most of the time is is a loose or broken ground wire at the back of the engine.
Great video best part at 11:10 I needed that lol! Got an '03 Tahoe I've been dealing with mine for like 6 months now!
Want to comment on this condition, I had a piece of tape (that I used to build up the crankcase ventilation tube) that got sucked up in the intake. It got caught at the throttle plate (LUCKILY), and it was preventing the valve from closing to idle position. I got all kinds of coded and the P1516, triggering the Reduced Engine Power mode. After I removed the tape, everything return to normal - throttle by wire was sent into a tizzy (and the REP probably prevented it from going any further). I was lucky.
I've heard of situations similar to yours. I usually tell people that one of the first things to do is to clean the throttle body. A dirty throttle body is a common problem and one of the easiest things to remedy. Glad yours turned out well.
Very cool. I just had this happen to me today in my 06 Monte Carlo. Gonna give it a try.
Thank you so much, I will be showing this to the mechanic.
I have the 2006 Impala. Same issues. Kicked the tire several times.
Failure mode on my 88 Silverado was that it would suddenly decide to floor itself! Wheeeee! ;] On the freeway in 5th, no big deal, downtown in 2nd gear things got exciting!
same with my civic lol, there was a hose/line that always dropped and got stuck between the throttle and the throttle body
@@DeluxFuzion Mine was a deteriorating Throttle Body Sensor. :[
I normally don’t sit and watch through the films but you were great not only did you help me show me but kept my interest way to go buddy and I am a blonde that was too funny I will say that to my clients as I’m cutting their hair now thank you again
DUDE!!! You are funny as hell!!! AND I learned something!!!!! Double Bonus!!!!
For my 2013 Buick enclave code p1682, I changed the main fuses box. My car used to shut off while driving. If u have service traction control - reduced engine power without any engine sign or code. Change the accelerator paddle.
My 2004 Silverado will shut nearly everything off while driving sometimes. It will stay running, headlights, and (AC) fan will run, but dash lights, (AC) compressor, radio, etc shut off. A few moments later, it will come back up.
Any ideas?
This really is the fix!!! Another comman problem that happens too is engine hot/ ac off. Just replace thermostat, it's stuck open do not waste time money on sensor!!!
lucashernandez8 I didn't replace thermostat just clear codes a.c. hot is caused by coolant temp sensor.
star child chevy dealer did same for my impala, just to have to take back to dealer and have thermostat replaced as i suggested to them from beginning.
Very good help...thank you very much!
I love your stories.Anyway great help thanks
This happened on my 2010 Impala. The check engine, ABS and traction control lights would all come on and reduced power mode would activate. I replaced the entire gas pedal assembly and it fixed it. $80 for the part.
Mac Neoh Same thing happened with mine! I was driving cross country by myself on the highway and it locked up so I couldn't steer. Managed to make it to an autozone and they diagnosed the problem and I had the part installed by my uncle.
Johnje Jasper Nice!! Saves you about $300 dollars doing it yourself.
Can you tell me the name of the part i need for my car the same thing is going on with my car abs the traction control is on and also the engine reduce lights comes on im a single mom is haard for me to get help especially me paying everything thanks God bless
solo Dios me Puede jusgar, I took my car to O'Reilly's Auto Parts store and had them test it with their code reader. The code came up for the gas pedal position sensor. There are other things that can cause this, so make sure you have the codes read on your car at an auto parts store. They will do this for free. If it is the gas pedal, you will be replacing the entire gas pedal. The tools you will need are; a 10mm ( I think it was a 10mm) socket wrench with a small extension, and a small flathead screwdriver. It will take about 35 minutes and less than $85 for the part to fix. Remove the 2 10mm bolts from the floor of the car that secure the gas pedal, pull the gas pedal out a few inches to get to the wire harness and use the small flathead screwdriver to unclip the wire harness, remove old gas pedal. Put the new gas pedal in in reverse order. It is really easy and they will charge a few hundred for this at the dealership. Again, make sure it is the gas pedal relay sensor by having the codes read at an auto parts store. This is a very common problem with the Impalas and Malibu. I hope this helps you.
Mac Neoh thanks alot so i just go to the O'Reilly store and ask them to do a code reader or i just let them know the problem im having with my car ?
All this shit happens after extended warranty expires!
Exactly!
In my case, after I've paid it off.
Desconectiun positive bateries, much eye with these, excelent job 👍
After having done all this with an 03 suburban and STILL going into REP, can I have my ecm reset or is this something strictly for 06 and up?
11:26, sounds like the neighbor is gettin some.
Ahhaahahaahhaah😂😂
@tonysand9641 I had to start reading comments,Was i the only one 11:26 who heard it? starting thinking i was going insane, but finally, someone else heard what i did around 11:30 after he kicks his car,hahaaa conveniently turns off the mic at that point to do some narrative work,
In my case, after cleaning the throttle body and running ground wires, the scan tool still 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.
Had a similar problem with a friends car. Two shops failed to diagnose it. The customer told me she lives in a very rural area so after doing a visual inspection, I found not only a nest but several chewed wires. This is why a thorough visual inspection as your first step is so important. Glad it worked out for you and thanks for watching!
I’m having same issues 3 shops 2 dealerships. I’m exhausted. Praying that mine gets fixed soon. I pray it’s just wires
I'm hearing this alot about rodent damage. These little guys are causing us a lot of problems! Especially if you live out in a rural area! Glad it worked out for you.
I hear that some dealerships are struggling with this problem. There seems to be a lot of different things that can cause this. It's easy to fall down that rabbit hole of possible causes. I hope they can solve it for you.@@moonshinesdream
Great video, explained all the way..
Thank you!!
Thanks for watching!
I put brand new Gm throttle body on my malibu to prevent this issue and it STILL done it. cleaned MAF sensor never done it again. traded that pos in.
I had the same problem with my 2002 Trailblazer about one year ago. When I was driving on a highway, reduced engine power light came on and it reduced speed to 15 or 20 mph. I pulled over and checked all connectors around throttle body and everything was fine. I was about to call for help when I just disconnected the battery waited for about 10 minutes, connected it back and then everything was fine, I did not do anything else. Like I said, that happened about a year ago and I have not had the problem again. Probably that is what happened to you sir, cause at the beginning you said you disconnected the ground cable from battery. I hope my experience helps somebody.
did you try flashing the PCM and updating the software in it like the initial bulletin stated todo before replacing all those parts?
cdc16730 negative sir. I just disconnected the battery and few minutes later connected it back and it has been working fine since then.
Most always it is the grond wire on the back of the engine that is the problem. Many many people have this issue just after driving their truck through a high pressure car wash also. This gets water up into places at the connectors that normally stay pretty dry even in big storms but once wet they corrode in no time and shortly after the warning flashes on the screen. In these cases it's not the ground but the connections fusing on the one plug to the throttle body motor.
Ricardo Macias thanks man this helped so much!
Barbellfishing go big or go home Great Sir!
I had this same issue with my 2011 Chevy Impala, replaced the gas pedal and It fixed the problem.
I wonder if that's my issue. 03 Tahoe. I've tried everything else.
I tried that didn't work
So In late January this year I had the exact problem before my road trip then After hours of research I install a new pedal and it works. BUT now end of October having the same problem I wonder if I put another pedal will it work.
I put a scanner and the problem is the main computer I haven't fucked with it but just letting you know
Video was a life saver thanks
Thanks awesome video. But do you think it will mess up something if I flip the butterfly manually?
Marlon Landeros You can manually flip the butterfly to get the sensor to line up. But do it carefully and don't let the white plastic gear fall out.
First thing. Check to make sure the battery cables are tite, oryour battery is good. If not theses things bet it's something else lol. I had this happen an this was my trouble hope it's as easy for you as this was for me. God bless you and yours my friend's, sorry for the smart ass remark.
damm boss you sure got me I almost threw that match and dinamite 😂
😜😜😜
Bro I died laughing at that 😂😂😂😂
Me too!
Very detailed lots of humor😎thanks
I think kicking the tire was the most productive part ! Lol.
I new a pretty good tech ,but he just vanished off the face of the earth. So I had to watch your video, To learn how to. Repair my vehicles bird socket and squirrel gear . Finally lined up and installed. Thank you for a very informative post. Signed won hung low.
It's hard getting birds and squirrels lined up.
I NEED THAT STICK OF DYNAMITE HE WAS TALK ABOUT FOR MINES!!!
That's why y'all have to take your new car to get it blessed with holy water at church grounds 😂
Man shut up
Really? Holy water? What is wrong with your brain...
Having this issue right now. Want driving and all of a sudden my check engine light came on and my reduced engine power was on my dash. Thanks for the advice. Will be doing this project tomorrow.
let me know how it went having the same issue
This guys is so funny 😂 .. dude u made my day 😂😂😂😂
My chevy camaro 2010 rs v6 has been randomly having this problem aswell. Where i would jus be in the middle of driving and it would say engine power reduced with thick white smoke coming out of the mufflers
Very entertaining and good car info!! Kicking tje tire was perfect definatly made me feel better. Lol
Muchas gracias. Muy bien explicado.
we had this in our 2012 impala LT. it is kinda gone now, the error stopped coming up and is now working without doing anything
Very helpful and funny at the end!!!
Bro this guy is funny as hell he kicked the car/tire saying its often overlooked
I recommend safety glasses when spraying the cleaner. It does not feel good if it splatters in your eye.
I learned that the hard way. It feel likes fire in your eyes.
I also get my neighbor to come over and kick the tire- saves on my sore foot😀
Thank you for providing this to all car victims, I mean car owners… victims
I have a 2011 imapala. I took care of it when it got recalled. Now about 3 years later it happened again. Only difference is my car didnt shut off on the freeway
I had the same problem brought it to the dealer first they said it was my battery terminals 3 days later came back on an come to find out it my gas pedal an the connection to the pedal they replaced the whole pedal for free an haven't had a problem sense an it's been a year or so now.
How much did they charge you for the whole procedure.
.
This was helpful and love your humor!
You have a great approach about making this repair and funny jokes. I'm going to try cleaning the original TB and see if that works, then I'll invest in the replacement kit. Thanks for this video.
@Hank Bridges Noted. The car drove better after the cleaning but started giving the power reduced blah blah message. Gonna install a new one.
@@Mister.MARVEL00 did replacing the throttle body fix it? Much appreciated.
Reduced power happened to me yesterday. 2009 Chevy Uplander. The gas pedal has been super twitchy for the last few weeks. Literally spin the tires every time the stop light turns green. I disconnected the negative cable off the battery for 10 minutes. It seems to be driving a whole lot better now.
sounds like a faulty accelerator pedal sensor.
@@lifeafterlife8417 alright thanks I'll give that a shot if it happens again.
People clean these drive by wire tb’s and mess up the sensors by moving the flap. The correct way to clean them, is to have someone in the vehicle with the key on and press the accelerator pedal all the way down.
I have a 2007 tahoe I install a stick on the seat to the gas pedal to press it down cause I was by my self...I went to look at the throttle n it never open up...any idea why the flap never open?
All you need is a stick of dynamite 🧨 and a match hahah this guy is so hilarious
How about for a 2008 Cadillac CTS? I’m having the same problem on mine, it says reduced power engine
For my 03 Tahoe it was a loose harness on the drivers side. Had a broken plastic clip but I taped it and it works fine now.
Was your Tahoe going in to limo mode because of that ? If you don’t mind me asking.
Limp Mode *
@@alexisgonzalez8676 it was going into limp mode but I used some QD electronic cleaner on the TPS circuit and taped the harness until I bought a new one and it fixed it. But maybe that was luck because I also replaced the TPS not too long after
I wanna say Thank you ☺️ I greatly appreciate you. You saved me about five hundred plus dollars. I watch your video because this just happened to me yesterday went to a Auto shop and told him this was the problem with my car after the fact he said it was the acceleration...but he did as I had asked him from this video and we are in motion 😁
You are very welcome! Thanks for watching and stay in motion!
How much would this cost to repair? Having this problem right now
$124.00

As soon as my Impala got the same thing, I literally got home and pulled up this video, thanks grandpa for your help and dynamite
Thanks for the video. I got the parts in today I'm about to start the install I'll let you know how it goes. What about the gear for the butterfly comment? Is there something that I'm missing?
Update?
My Mom’s car is a 2010 GMC. As we were driving back home, the car went really slow and starting shaking.
were you able to find a fix? same thing
The real fix is!!!!!!!!!!!!!!!
Cut the boots off the battery cable ends and clean both sides with sand paper. Cleaning the one side is not enough the lug side is never serviceable unless boot is removed. I just used dielectric grease to cover instead of buying new cables. Also remove the primary cover and shroud around the fuse box under hood. Remove the positive lugs. Most gmc have three 1 from pos battery cable and two smaller ones powering the computer and something else. When you look at them they look good no corrosion but if you look closely it will look Grey. Sand both sides of the ring connector and the lug surface. Overtime no matter where you live air temp and moister slightly oxidize the metal. What happens is one of these powers the pcm and the others send power to vital sensors. Most of the time as long as its not a broke tps wire or if you accidentally stretch while in drivers seat and kick the pedal connection this connection oxidation does not allow the pcm to have a solid constant battery voltage so when the pcm dedicates the 5v reference to the PETAL AND TPS they are varied. Thus eventually the pcm does not allow the key on pretest yes your gmc will tell you reduced power without starting. Turn key on and wait about 10sec and if the pedal/tps agree nothing will display if not it will display reduced engine power. Also if you are having REP while driving add a new ground on drivers side of engine bay from firewall lug to one of the bolts on the bolts on the alternator bracket. Also grounds underneath drivers side frame rail, under radiator support, and the main negative lug on drivers side engine block. Also on the passenger side engine bay there is the pcm ground that comes out of the the big loom on the firewall goes out to the back of engine just like the braided one it is covered in crinkle cover but they are black wires usually two wires. Cut as low as possible bring up and solder one thicker wire estimated at double the gauge of one of the wires so you won’t have resistance problems. Remove the braided ground from firewall and remove one bolt from the third coil pack closest to the rear of engine and attach the braided ground don’t double ground this remove it because you could cause what’s called a looping ground. Electricity goes to path of least resistance. Since the braided line is very hard to remove from rear of engine block attaching the firewall end back to coil pack bolt leaves it null/void and tight so it won’t rub anything else. Also use a ground wire insulated I think it was 15in from parts store $12 for the new firewall to alternator bolt connection. I guess I could have made a video but I’m posting this on comments in various places share if you think it’s a good thing. My Rep problem is solved no tps,pedal, or throttle body replaced I researched this problem for months because I know a shop would just hose me for parts and I think most sensor issues and there lifetime are determined by there power/ground consistency. 2001gmc Yukon slt 260k miles. Good luck guys.
I was 5 hours away from home in George Town Kentucky going to fort Wayne Indiana. Power shutting off. Watched this video. Bought parts and tools. Swapped out throttle body in front of an AutoZone . 60 miles down the road now. No problems. You're a life saver !!

2007 cobalt the message sending unit says reduce engine power .. you think it's the same problem. Cause when we got it diagnosed and got a code saying camshaft sensor.. replaced it does the same sh ut t off while you driving .. if you can help
where did you get the new gasket? special order off amazon? or...? thanks, nice video!
Autozone. They had to order it but I got it in 2 days.
In side the black plastic tpi on the throttle body there is a gold colored plate, under that there is a contact plate with 4 contacts, if you look at them with a magnifying glass, 1 is separated. You could possibly solder it back together but its so small .
Or just throw out the factory TB and get a Hi Performance one. I'm sure there is one made for that V6 by now
@extremedrivr were trying to save money my bro not give my whole brain to them
Got lucky with mine. I just cleaned my throttle body still attached.
Ok so I have reduced engine lite blinking codes are as follows o2 sensor 1 bank 1 o2 sensor 2bank 1 up and down stream and maf mass air flow replaced all three parts Upstream Downstream and mass air flow still does the same thing could it be my throttle body with the TPS even though my scan tool is reading throttle percentage
What kind of vehicle? Reduced engine power could be a separate problem.
Currently broken down in Florida heat I needed that in swift kick 😂. Made me feel better about the situation

Life After Life I got a P0010 code. I fixed transmission then starter gave out I fixed that now I got this issue it won't go passed 20 I don't know.
Betina Rios shutting the car completely off for 2 minutes (when you can pull over somewhere safe) will reset it temporarily. I did this for a couple days until I fixed mine.
A pair of needle nose pliers makes as good a screwdriver as a screwdriver makes a pair of needle nose pliers. Both highly useful tools, but hardly interchangeable. The removal of the spring clips was downright painful to watch. When do you plan on installing the new gasket?
