Description:

  • Sensor Reference Voltage E Circuit Low

Possible Symptoms:

  • Check the wiring harness and connectors for any loose or damaged connections.

  • Inspect the sensor reference voltage circuit for any short circuits or open circuits.

  • Test the sensor reference voltage using a multimeter to ensure it is within the specified range.

Possible Causes:

  • Faulty sensor reference voltage regulator or module

  • Short circuit or open circuit in the wiring connected to the sensor reference voltage circuit

  • Faulty sensor that is connected to the sensor reference voltage circuit

  • Problem with the power supply or ground connection to the sensor reference voltage circuit

  • Malfunctioning Engine Control Module (ECM) or Powertrain Control Module (PCM)
