TP Sensor circuit low voltage
TP Sensor circuit low voltage
Documented for: 2.0L gasoline; 2.5L/3.0L gasoline · System(s): EMS EOBD, EMS OBD II · Factory MIL flag: 2 · Default action: ECM Default: –Idle speed controlled by fuel injection intervention –Idle speed adaption inhibited –VVT inhibited
Common causes
- TP Sensor to ECM sensing circuit: open circuit
- high resistance TP Sensor failure
- TP Sensor to ECM sensing circuit (TP1): open circuit
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)
