got that on my gauge screen and engine disabled. car would not start for a while then it did and i made it home. barely any power and ugly idle. got the codes and i got a p0122 throttle position sensor circuit low voltage and a p0223 app sensor 2circuit high voltage

anyone know what can cause that and how to fix it? hopefully thats the prob

car fires up fine but has a ugly idle

 

ooooo Rico this happened to me.. did u rewire ur throttle body wires or repin em or something?

 

did you open the butterfly on your throttlebody with your hands at any time? i just ruined my tb from doing that and had to order a new one. throwing the same codes

if you have hptuners, hook it up and with the ignition on but the car turned off, press the gas pedal in all the way and let it all the way out and see what the % of position for the TPS is.

mine went from 33% closed to 88% open, which means it was just fucked. my fault for opening the butterfly with my hands

 

All better. Just needed my magic touch from how many miles away?

 

solveed the problem. tb harnesss was loose

 

i just got a letter from gm about possible faulty cat. convertors. they give your symptoms.

 

Damn ya fixed it?

 

mine done that today when i forgot to plug the tb in... then it kept doing it after i plugged it in. so i shut it off for a minute and started it. idles just fine... but still a light on

 

Light will stay on until the a predetermined number of full cold to warm startups.

 

haha glad ya fixed it... takes me too long to type.

 

this **** scared the hell out of me tho lol

 

haha me too... i thought i screwed up my tb when i ported and polished it. now the damn thing whistles when i take off its funny watching people look for the whistle

 

man i though somehowe the motor went byee. i was already thinking **** it fully built block etc lol

 

yeah it sounds awful huh like a helicopter, reminds me of the stg 4 cammed cobalt on youtube...

 

 

i take it you watched the video?

 

i think long ago lol

 

im having this problem too....but i also have the code p2135... any ideas?

 

I had that happen one nite , i disconnected the battery for 20 minutes and reconnected it and everything was fine. Next day sold the car thinking it was demon possessed and now here I am driving another SS lol

 

I've been having this problem the odd time to but I think it is my methanol some how getting into the connector on the throttle body.

 

mine was the tb harness wasent plugged all the way after putting it back on

 

i will check that and see thanks
