Hi All,

Recently the Electronic Throttle Control warning light has been coming on,
What does this mean? & what can I do to fix it?

Cheers

 

That is frequently a sign of low system voltage. Best thing to do is make sure your battery cables are all clean and tight and have your batteries load tested, if one is bad be sure to replace both at the same time.

 

Thanks for your advice, I will get the batteries check out today.
Also recently, I was asked if I "ride the brake pedal" because my brake lights are on while driving around town. So I have found out that if you pull back up on the brake pedal the lights go out so, would this also cause the Electronic Throttle Control light to come on? So is there an adjustment that I could do to fix the problem?

 

That could very well be the problem. Our trucks do not like to have the throttle and brake on at the same time. Should be giving you a code to that effect.

 

does it flash or blink they can mean two different things and also do u loose power my truck did the same thing changed throttle body, gas pedal three times, checked batteries changed them checked some grounds and still same thing. it ended up being the turbo i guess it was dirty so i removed the air filter idled the truck up and put some water with a spray bottle into the intake a walla problem fixed hasn't happen since and its been a year.

 

the code mine was giving is a p2121. i have egr dpf delete 5" turbo back and h&s tunner the truck did it before and after i put all this stuff on. it took me a long time to figure the problem out so hope this helps you.

 

Hi Blowing Coal.
I just bought a 2016 and the same thing is happening. I get the flashing ETC lightening bolt light. The truck runs fine then the check engine light comes on periodically then it loses power and acts like it wants to stall. It has 611 miles on it. Took back to the dealer and they say it is the gas peddle sensor and wire. They are ordering the part and it is supposed to be fixed by Tuesday. I have read several forums and this issue seems to be a real gremlin of a problem. All of the remedies on other forums are as stated in your post above. Thanks for your post. I hope and pray this fixes the problem.

 

I would really try and get the turbo looked at. But with the mileage you have seems like a factory issue. the dealer also told me about those same wires supposedly they get hot and break or cause a issue with voltage from them grounding out. if you need anything pm me also don't inject water into the engine hot let it cool completely idle up spray a heavy mist until you hear the turbo blades hitting the water then stop let the truck run a few min after turn truck off reset codes and hopefully you will be good. just really make sure the engine is cold....
