TP sensor replaced but check engine light still on. How can you tell if it is a computer problem?
I had the TP sensor, PO102, PO113 Intake Air temp circuit replaced. They say it maybe
electrical or the computer(possibly). The car has 177 thousand miles. How can you tell if it
is a computer problem?
A live data scanner is the best way to tell, if all of the sensor reading correspond with the book readings then the ECM may have a failure. Have you done a hard reset on your ECM?
Another diagnostic was done and what was said was; PO122 + PO123. CHECK tps check harnesses (electrical) from throttle body to computer. It drives well, so i am hoping it is not the computer
As the ECM changed codes after repairs it sounds like there is a wiring problem, grounds are a high probability.
ok thank you.
