EFT Sensor range / performance
EFT Sensor range / performance
Scope: 2.5L/3.0L gasoline · System(s): EMS OBD II · Factory MIL flag: 2 · Default action: ECM Default: –Default value of 25 °C (77 °F) used
Common causes
- EFT Sensor to ECM sensing circuit: high resistance, open circuit, short circuit to ground short circuit to high voltage EFT Sensor to splice sensor ground circuit: high resistance, open circuit EFT Sensor 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)
