SPN 441 - FMI 3 (Fault Code 293)
SPN 441 - FMI 3 (Fault Code: 293)
SPN441 FMI3
CODES:
Fault Code: 293
PID(P), SID(S): P441
SPN: 441
FMI: 3
Lamp: AMBER
SRT:
REASON: Auxiliary Temperature Sensor Input 1 Circuit - Voltage Above Normal or Shorted to High Source. High signal voltage or open circuit detected at the OEM auxiliary temperature circuit.
EFFECT: None on performance.
Circuit Description:
The original equipment manufacturer (OEM) has the option of wiring a temperature sensor input to the Cummins electronic control module (ECM). A specific calibration is then created to recognize this temperature sensor input.
Component Location:
The OEM temperature sensor input will vary depending on application. Refer to the OEM troubleshooting and repair manual for sensor location.
Shop Talk:
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.
