Throttle control position error
Throttle control position error
Scope: 2.5L/3.0L gasoline · System(s): EMS OBD II · Factory MIL flag: 2 · Default action: ECM Default: –Throttle motor and throttle motor relay disabled –Throttle valve opening set to default value –Idle speed controlled by fuel injection intervention –Idle speed adapti…
Common causes
- Throttle adaptions not performed after battery disconnect TP Sensor disconnected TP Sensor to ECM sense circuits: open circuit, high resistance Throttle motor relay failure Throttle motor relay to ECM circuit fault Throttle motor relay power supply open circuit ECM ground circuit fault (relay coil drive) Throttle motor to ECM drive circuits: open circuit, short circuit, high resistance Throttle motor failure Throttle body failure
Quick checks
- Confirm freeze-frame and conditions when the code set
- Inspect connectors, grounds, and harness for the circuit named in the code
- Compare live sensor values vs expected (unplugged/biased sensors are common)
- Swap coil/plug to another cylinder if misfire is cylinder-specific
