TPS voltage @ IDLE & WOT ??
#1
![Default](/forum/images/icons/icon1.gif)
Hey guys, new to this forum and seeking some help!
I have a 2001 c3500hd with the 8.1L. I have codes p1220 & p1221. I changed the Tps sensor but still have same codes. I decided to check the tps sensor voltage just because it’s an aftermarket part. Hoping I did this right..here are the readings I got for the tps….
tps sensor #1
WOT - .35v
IDLE - 4.01-4.02v
CLOSED - 4.55v
TPS # 2
would have same reading of 4.85 through out the movement of the throttle body. It wouldn’t change at all! My question is: Is this normal? Does anyone know what the voltage should be??
any help would be very much appreciated 🙏🏽
