|Fault Code: 298
Auxiliary Pressure Sensor Input 1 Circuit – Voltage Below Normal, or Shorted to Low Source. Low signal voltage or open circuit detected at the OEM pressure circuit.
None on performance.
Auxiliary Pressure Sensor Input One Circuit
The OEM has the option of wiring a pressure sensor input to the Cummins ECM. A specific calibration is then created to recognize this pressure sensor input.
The OEM pressure sensor input will vary depending on application. Refer to the OEM troubleshooting manual for sensor location.
Possible causes of this fault code include:
- Signal circuit open or shorted to ground in the OEM harness or sensor.
- Supply line open or shorted to ground.
