Cummins ISX CM870 (2003-06) Fault Code: 221 PID: P108 SPN: 108 FMI: 3/3 Barometric Pressure Sensor Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at barometric pressure circuit.
The barometric pressure sensor shares supply and return wires in the engine harness with other sensors. Opens and shorts in the engine harness can cause multiple fault codes to be active. Before troubleshooting Fault Code 221, check for multiple faults.
Possible causes:
1)Open return circuit in the harness, connectors, or sensor.2)Signal circuit shorted to sensor supply or battery voltage.
Possible repairs:
1)Repair or replace the engine harness.2)Replace the barometric pressure sensor.3)Replace the ECM.
Cummins ISX CM870 (2003-06) Fault Code: 219 PID: P017 SPN: 1380 FMI: 1/17 Engine Oil Level Number 2 (Remote) Low – Maintenance. Low oil level detected in the Centinel? makeup oil tank.
Cummins ISX CM870 (2003-06) Fault Code: 214 PID: P175 SPN: 175 FMI: 0/0 Engine Oil Temperature – Data Valid But Above Normal Operating Range – Most Severe Level. Engine oil temperature signal indicates engine oil temperature above engine protection critical limit.
Cummins ISX CM870 (2003-06) Fault Code: 213 PID: P175 SPN: 175 FMI: 4/4 Engine Oil Temperature Sensor 1 Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the engine oil temperature circuit.
Cummins ISX CM870 (2003-06) Fault Code: 212 PID: P175 SPN: 175 FMI: 3/3 Engine Oil Temperature Sensor 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage or an open circuit detected at the engine oil temperature circuit.
Cummins ISX CM870 (2003-06) Fault Code: 197 PID: P111 SPN: 111 FMI: 1/18 Coolant Level – Data Valid But Below Normal Operating Range – Moderately Severe Level. Low engine coolant level detected.
Cummins ISX CM870 (2003-06) Fault Code: 196 (3 wire) PID: P111 SPN: 111 FMI: 4/4 Coolant Level Sensor 1 Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the engine coolant level circuit.
