  • •Voltage feedback from the sensor is above the limit defined in calibration
  • •Voltage at the ECM AUX_Ana_PU exceeds 2.5 volts
  • •High oil temperature resulting in increased voltage feedback to the ECM
  • •High resistance in wire harness circuit
  • •Faulty Oil Pressure/Temp Sensor
  • •High oil temperature (exceeding maximum allowable limit of 235F for WP or 250F for 20L)

Suggested Actions

  1. 1Replace Oil Pressure/Temp Sensor
  2. 2Replace wire harness
