None on performance.
Auxiliary Temperature Sensor Input 1 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:
- Open return circuit in the harness, connectors, or sensor
- Open signal circuit or shorted to a voltage source.
