fix for p0123 gmc envoy
Faulty fuel injector.......had to replace 2 on my 2000 Intrepid...Good Luck
Throttle Position Sensor(TPS)/Accelerator Pedal Position Sensor(APPS) signal voltage high.
Trouble code P0123 means:Throttle/pedal position sensor/switch A circuit high input
A P0123 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too high a voltage. Symptoms may include: Rough idle High idle Surging other symptoms may also be present A code P0123 may mean that one or more of the following has happened: TPS not mounted securely TPS circuit short to ground or another wire Faulty TPS Damaged computer (PCM)
the code P0123 means, Throttle Position Sensor/Switch A Circuit High Input. sounds like a wiring problem to me. I had the same problem with a 99 Toyota tocoma when i replaced it i had to reset the CPU. On a dodge you should be able to disconnect both batteries for 15 mins to 1 hour and it mite reset.
high voltage at the tps.
P0122 - Throttle Position Sensor circuit low input. P0123 - Throttle Position Sensor circuit high input. Change your TPS(Throttle Position Sensor). It is located on the driver's side of the throttle body with a three wire connector, usually white. If you need instructions, reply back.
