OBD II Fault Code

  • OBD II P008F

    OBD-II Code Powertrain Control Module (PCM) failure is defined as a Engine Coolant Temperature/Fuel Temperature Correlation

    The Engine Coolant Temperature Sensor tells the engine control module (PCM) the temperature of the engine coolant. The Fuel Temperature Sensor tells the PCM the temperature of the fuel. The PCM compares the two sensors to determine if one or both sensors have lost their calibration. If the PCM determines one or both sensors have lost their calibration, the PCM will set code P008F.

    Common Problems That Trigger the P008F Code

    • Engine coolant temperature (ECT) sensor failure
    • Fuel temperature sensor failure
    • Powertrain Control Module (PCM) failure
    • Wiring issue
