I have a 2002 swb Silverado single cab with alum ls1 cam ect.... ive had a p0122,p1122 and every thing I do to correct it does not work ive replaced sensors multiable
times went over harness thoroughly and traced wires all the wat to comp, I recently discovered while using scanner that tps goes to 16 percent at idle so I unplugged tps and used voltmeter on signal side and it outputs .15 to .31 or so when it should be receiving voltage so my question is does this sound like a internal computer issue ?
I went ahead and ordered one, but would like anyone's thoughts to this matter
