Auxiliary Temperature Sensor Input 1 Circuit – Voltage Below Normal, or Shorted to Low Source
|Fault Code: 294
Auxiliary Temperature Sensor Input 1 Circuit – Voltage Below Normal, or Shorted to Low Source. Low signal voltage detected at OEM auxiliary temperature circuit.
None on performance.
Auxiliary Temperature Sensor Input One Circuit
The OEM has the option of wiring a temperature sensor input to the Cummins ECM. A specific calibration is then created to recognize this temperature sensor input.
The OEM temperature sensor input will vary depending on application. Refer to the OEM troubleshooting manual for sensor location.
Possible causes of this fault code include:
- Signal shorted to ground in the harness.
- Signal shorted to return or ground in the sensor.
