Question about 2005 Chevrolet Trailblazer Ext
answer ,why not fix the obviously bad, want to blow a fuse and get stranded.? many circuits on all cars are shared.
most books.web/Fsm or other sites for DTC mostly fail to say
"or lost power to same "
as a tech , we dont have to learn that, we know, that.
the first thing that must work with all electronics is POWER>
no power no joy, end story. we check it for drop and noise.
Possible causes (simplistic)
- Faulty electric throttle control actuator (TP sensor 1 and 2)
- Throttle Position Sensor harness is open or shorted
- Throttle Position Sensor circuit poor connection
- Faulty accelerator pedal position sensor
