Will the check engine light come on due to this

Paul Ott did it work for u I got same message on my 2011 equinox this morning

Desmond Connally yes. The dealership ended up doing the excessive oil consumption "recall" and cleaned the throttle body and she runs like new!

I just drove with the mass air flow sensor unplugged for about 4 months. With it plugged in, i couldn't get above 40 miles an hour. Now it won't go above 10 miles an hour.

I realize I am kinda off topic but do anyone know of a good place to stream new tv shows online?

@Braylen Nasir i use Flixzone. Just search on google for it :)

@Luka Layne Yea, have been using FlixZone for since march myself :D

@Luka Layne Thanks, I signed up and it seems like a nice service :D I appreciate it!!

@Braylen Nasir No problem :D

Jon Hoffman change plugs gap tourque to spec!! Air filter!! Pour a very good cleaner in fuel tank also clean Tb with sea foam spray cleaner do not touch flap manually only spray as someone is idling engine! If your battery has not been replaced do so at 100,000. If it persist change Tb sensor only not the entire unit

@@kekelove6784 sounds like you need a new mechanic

Yeah, I just did too. I’m at 160,000 miles. I’m in Oklahoma. It seems like the cold is exacerbating the symptoms of this problem. I haven’t done mine yet. Have you had luck with yours? I also put seafoam in the oil and gas tank .

Joel Gonzales did it work fir your 2011 terrain? I have the same problem same car

Paul Perez Paul Perez hey Paul, I did fix mine. I changed the throttle body but it didn’t work. I don’t know about your terrain, but my terrain eats oil so occasionally I have to add oil to it between oil changes. Come to find out, I added too much oil to the crankcase. That oil ended up in my air intake assembly through that small tube on the left side of that air intake assembly that connects to the crankcase. That tube is some kind of exhaust vapor recycling system. If oil gets up in it, it causes that rough idle. Pull that little tube out and see if you have oily junk in it. That might be it.

Brian of Brian and how did you clean that tube or you change it?

Paul Perez I changed it but that’s only because I broke it taking it in and out so much. If what I described is your problem, you need to check your oil level, and make sure your oil isn’t overfilled. If so, drain to proper level. Pull out the hose to see if you see a muddy brown oily gas smelling junk. If that hose is clean, it may be your throttle body. Here is that hose part just in case. You have to order it online because part stores don’t carry it. www.amazon.com/general-motors-12619363-Hose-Pcv/dp/B015NE93AK

Did you figure out what was the issue?

I've had mine for 2 weeks and it started screwing up at day 5. 🙄

@@cainguardian4693I had my 2012 cheverlot equinox for a month and a half and I'm already having issues worst car ever to buy from what I'm experiencing right now reduce engine power stability track engine light car gives me a headache don't know what's wrong with it I need a good trustworthy mechanic cause the 1 iv been to aint it my car was fine until I took it to the shop smh

@piscesrealm9839 this is going to sound absolutely wild, but my Equinox ended up doing that to me as well very quickly and it took an oil change to fix the throttled engine issue. Turned out to be something cracked in my engine that caused it to leak my oil fast af. Never figured out that track issue because the damned thing broke down on me before I could lol

Similar issue, did you figure it out?

Ok. So I did this and the throttle was filthy. It did fix the issue. Thank God! I was so scared it was going to be a computer issue. Thank you so much again!

Same problem here 2010 equinox. DID it work for u, I'm about to try it

About to try it now thank u .. *JUST GOT THIS CAR IN APRIL*.. SMH......all this just happened the morning.....I didn't know what was going on... Thank goodness I wasn't going that fast when it came on!!! ( Our luck, if not one thing it's another)😒

2012 Chevrolet Equinox and just tonight the same codes came up; Engine Power is Reduced! and Service Stabili Trak. Thank you for the video and wish me luck, I’m going to try doing this myself.

I haven’t tried cleaning the throttle body yet, but was curious what the dealership would charge. Chevrolet dealership in Los Angeles quoted: $128.00 for diagnosis (but if proceed with the repair they advise this diagnosis fee is deducted from total repair costs) $150.00 to clean throttle body $500.00 (only part cost) for a new throttle body

I might have the same car what issues and how to fix it ? did u just clean it? without taking it apart

I have a 2013 chevy equinox the battery light came on then the service charging syatem came on then the stabilitrack and service power steering and then truck shut off i took the alternator to autozone to get it checked they said it was good charged the battery too and still doing the same thing any idea or can anyone help!!!!

I'm not a mechanic and only do basic troubleshooting and maintenance. I can't provide you any further advice of value past what I did that fixed my vehicles.

Elly The Cockatoo change plugs and air filter!!!!! Sounds crazy but yes!! Try regapping plugs and remove air filter you will see!!!

The hose on the side is part of a system that recycles waste back into circulation to reduce overall emissions as I understand it. It is poorly designed and has come under scrutiny from many people as it causes unnecessary gunk to build up on the throttle bottle. It likely smells like gas because it is excess waste from system.

@@DIYwithChris The hose is actually a clean air intake, the PCV is integrated into the EGR system behind the engine. If you are getting milky liquid in your cover like Marsha it means there is likely a clog in the EGR area and the engine has nowhere else to send blowby. Need to get the dealer to inspect that. Some people have this problem in cold climates, their EGR clogs, the engine spits crap back through this clean air intake, the sludge freezes in cold weather, then the engine blowby has nowhere to go and blows the rear main seal. One precaution you can take is to replace the stock oil filler cap with GM FC219. It wasn't designed for this vehicle but works fine. FC219 is a pressure relief cap that releases pressure if it gets too high. So if you are one of these people in freezing climates with a clogged EGR and the sludge at the end of your cold air intake is frozen, it will seep out the oil cap and save your rear main seal. Although like I said if you see the milky sludge you need to get down to the dealer and see about the clogged EGR, instead of getting to the point where you need to release pressure out of your oil cap....

How did it go?

Sooooo Took the 4 bolts and quick connect off. Cleaned. Put back on,spiked at 3000 rpms. Did all the tricks this and that. Mechanic said to swap it out with a new one, did that same 3k spike. Tried all the tricks and that. Come to find out a GMC dealer has to hook it up to their computer. 15 min 140 bucks for their labor. Fixed. What a pain in the butt Altogether cost like almost 400 bucks. Ewwww

When I took in both of my vehicles for the same message, I was given multiple different reasons for the code and how to fix it to include replacing the ECM, throttle body, etc.. I took the opportunity to perform the easiest maintenance I could at home instead of paying them $500+ and it worked. Cleaning the throttle body solved the same issue across both of my vehicles fortunately. I cannot guarantee that it will fix yours but I believe it's worth a try.

Jaiden Itis I have the same problem with my car did you figured out what is was. I have changed every part that you mentioned and it still turns off on red lights they only thing I haven’t done to it is clean the throttle body

Magdiel Alvarez yes mine was low oil no oil at all! I was comfortable taking my truck to oil changes and paying for them to be done , this past week my truck would jerk forward and in every red light turn off I until it turned off on me in the freeway 80mph made it home changed out my filter it was disgustingly black, all those times I went for an oil change they never would drain out my old oil just continue to add but this last time no oil was added I was scammed so check your solenoids they roughly run on oil , clean your throttle body as well remember that is the heart of the truck if it’s black and dirty clean it Out but if it’s in terrible condition change it out for a new one! I recommend use the dexos oil as manufacturing recommends , you might also want to check your timing chain if it’s loose out of place etc so far my code went away and truck runs great no issues hope this helps

I would definitely try to clean it first. It's very inexpensive and doesn't take much time to do.

Herbert Jackson What did you do?

It is best to remove the entire throttle body and clean from both sides. I have personally done this twice on different vehicles and I have moved the butterfly valve with no issues.

Likely something else I would assume.

@@DIYwithChris Do you have any ideas on what it might be? I went ahead and cleaned the throttle body because that's what worked the last time. While in there I realized one of the short black tubes had been electrically taped instead of replaced, so I did that. Then I realized the plug holding down the plastic guard over everything was missing so figured that may be allowing too much air in and choking it? So I put in a new plug. But I also noticed the seal around the intake hose was not folding around the entire outer lip. I still think it may be more of an electrical issue because sometimes my window on the ride side cannot be moved with my door switch from the driver's side and the volume freezes where you can't change it by the dial. Does any of this foster a culprit or idea on your end as to why my car is going into Engine Power Reduced mode?

@@annagorges9586 reduced engine power mode can be initiated for a multitude of different things. It is a safety feature that when the vehicle detects something wrong that could cause possibly irreparable damage to the vehicle, it reduces power to save your engine while leaving just enough capabilities to drive to a shop. Every time that the message has populated on my vehicles it has been the throttle body however that is not the only trigger. Yours does sound electrical based off the description however I am not a mechanic and cannot offer valid advice further than my experiences. I would first run a diagnostic scanner to see if any codes pull up and move from there. If nothing pulled up, I would likely consult a professional.

Noah Ortega time to replace water pump and thermostat!! As far as reduce power!! Change plugs and air filter!! Spray sea foam spray cleaner onto Tb while someone is idling engine!! Do not move flap manually!!! Also if car had more then 100,000 miles change battery!! Yes battery as today’s card don’t have distributors anymore so they need very good source of power (battery) to operate computer transmission and coils!! If reduce engine comes back, change the Tb sensor only not entire unit!!

From the research I did at the time, it was a large list of culprits. I was lucky it was the easiest mentioned. Other factors included ECM module malfunction, recalibration of throttle body, component failure unrelated to throttle body that triggers low power (this list is large and a high possibility).

Did u ever fix it mines doing it

+Anon if the whole throttle body was replaced, a newly purchased one should come with the chip and not require additional programming. Sometimes, messing with the throttle body and maneuvering the intake flap without disconnecting it first can confuse the chip and cause it to need to be reprogrammed.

That makes absolutely ZERO sense! The "chip", the Throttle Position Sensor, keeps the correct accelerator pedal position balanced with the correct throttle plate butterfly valve opening so air-fuel ratios are correct per what the rpm, gearing and speed are.

I have replaced throttle body already

That’s what’s going on with me I got 2018 gmc Buick regal sportback I changed throttle body then the map sensor then I changed crankshaft sensor and still not working smh

Sorry to hear that. This has fixed this problem every time on my 2010 Terrain and 2011 Sierra. Best option is to buy a diagnostic tool and read the code yourself before taking it to a mechanic. Each time I do it the code reads a malfunction with the throttle body.

Roseanna Bruce Did you reset the ECU probably have to erase the bad codes then unhook the negative terminal for how ever minutes it needs to resets the ECU because it still remembers the old code oh and the new throttle body needs the be retrain to work with both the gas padel and ECU good luck...

My 2010 GMC Terrain. The dealer told me it was the engine. I cleaned the throttle body, changed a new engine, changed the wiring,changed throttle body for the third time and Still doing the same thing.

Neither of mine made a loud noise, they acted completely normal other than not being able to shift higher and accelerate above about 15 mph.

@@DIYwithChris do have any ideas what could have happened? I had just bought the car on Monday, it ran like it was brand new. Shifted fine, floats like a boat, no shakes or rattles. Motor purred like a kitten. I fill up with gas yesterday, drive 1/2 mile up the road and the car slowed down, lost acceleration, and then died. Engine check light came on and traction control warning came one. I was able to pull it off the road. And then when I tried restarting it, the motor sounded really loud, almost like a knock. The oil was just recently changed so that's fine. Also the motor was hot it burned my hand. It's my only car and would like to fix it.

@@MrsRebeccaLinn , I don't know right off as I'm not a certified mechanic. You might check some forums or try to purchase a code reader. I use my code reader to diagnose most of the problems and go from there. I was able to pick it up for about $100 at AutoZone. It definitely helps so that a dealership or individual doesn't give you crap.

Patchouli Princess did you ever figure out what the problem was? I’m literally going through all of what you described right now unfortunately.

Barry Holmes wrong fuel? Diesel fuel instead of gasoline?

Sorry to hear that. I have had to continue to clean mine once a year. It is a design flaw.

is it a possibility the type of gas we use is causing this sticky gunk build up in the throttle body curious about to clean mine for the first time after seeing this video

theanag raman it’s a brand new fucking car wtf. Take that back to Chevy and have them replace the throttle body. It’s new so you can be bossy about fixing the car for free. My 2019 Malibu I just got just right now like 10 minutes ago said something about the battery to Turn on the car because the battery is low. But the lights weren’t dim. I check the battery voltage and it’s at 13.8 and idk what’s the problem.

theanag raman was your problem covered under normal warranty?

Wtf 2019......

@@vegasbab.y3740 So why did you tell

Some control modules must be recalibrated if the throttle body and components were manipulated manually. This could one of many possible issues. I've cleaned my throttle bodies on multiple vehicles without any issues or need for recalibration.

@@DIYwithChris thanks I may need to contact a GMC dealer

Mine wouldn’t start and it was the timing chain at 70,000 miles. Now i have low compression and misfire on number 2 cylinder.

Your battery

How did u find out. I replaced old battery with new and everything stopped And old battery was testing good condition but was fup with something we don’t know about but it fixed 1000 problems

The same just happened to me right now. What did you do? I smelled the substance and it smelled like gas, so I reconnected everything back and stopped working. Did you find out why that substance came out? How did you fix your car? Please reply, as I don't want to take it to a mechanic if I don't have to.

My truck did shake when it had this same problem. Due to the experience I fixed this car before it got that bad.

If your car shake while you idle, it can be your camshaft position actuator solenoid

I have a 2015 terrain in limp mode And a good 4 ounces of oil inside intake. I cleaned it and throttle but it keeps f up sometimes it runs great then it flips out Now it won’t start at all. What can this be????

Yes, I've had the same message and fixed it the same way on my 2011 Sierra as well.

DIY with Chris Home Projects Our 2014 Silverado started shaking, lost power, and the “reduced power” message came up. We were able to start the truck and the speed will not go passed 40mph. Do you think this is the same issue?

@@RubyGxoxo both of my vehicles did that same thing. It's called limp mode. It can turn on for various reasons but cleaning the throttle body has fixed the issue all 4 times it's happened.

DIY with Chris Home Projects we followed your video and sure enough, the throttle body was disgusting. Cleaned it and Put everything back together, but the idle is still rough, O2 sensors are reading not enough fuel, and the fuel rail pressure is surging on the OBD reader. Any suggestions? One more thing, our left back light bulb has been having issues. Someone told us it could be causing a short somewhere.

@@RubyGxoxo the throttle body has a control module that can be disrupted when the unit is forcibly moved or taken apart. That may be causing the issue with your mixture. I would first ask a dealership to calibrate the module, if that doesn't work, the whole thing may need to be replaced. As for the light, yes that sounds like a possibile short.

+melly mel sorry about that. Worked for both of mine.

Lol😁👍🏼

Oceanic Flight , yes I do.

DIY with Chris you should do more videos on it. I have the same year and model

Pathetic Circus they suck!!! With all these code reading bs!!! Change plugs gap and tourque to spec!!!!!!!!! Battery too! Then run very good cleaner in fuel tank and spray sea foam spray in Tb while someone is idling do not move flap manually!! If this persist change Tb sensor only not whole unit!!

+Brandy Day , the way I mentioned is only a one thing that may be causing the issues. It is not always the throttle body. You can run a diagnostic check on it for a code or take it to somebody who can further discuss the problem.

What I've researched, the problem is the throttle position sensor, which unfortunately you can't buy by itself.

Pulled the codes. We replaced the throttle body 2 weeks ago and so far so good! Fingers crossed!

How much did that ring you for cuz my car is in reduced engine power

@@hunchohefner3545 I had to pay for timing parts that wasn’t covered under the service bulletin. It was just south of a thousand bucks, that time.

@taylorchandler I’m taking it to see what’s wrong with it reduced power engine pops up an then while it’s started it makes a squeaking noise

Ann Barondick and thats why you probably dont know shit

Did you get it fixed?

I would have to agree, for this model
