PACCAR PX-8 CM2150 (2007-09) Fault Code: 145 PID: 110 SPN: 110 FMI: 4 Engine Coolant Temperature 1 Sensor Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at engine coolant temperature circuit.
Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, recalibrate the ECM.
The engine coolant temperature sensor shares return wires in the engine harness with other sensors. A shorted return can cause multiple fault codes to be active. Before troubleshooting Fault Code 145, check for multiple fault codes.
Possible causes:
1)Signal shorted to ground in the harness
2)Signal shorted to return or ground in the sensor.
Possible repairs:
1)Replace the engine coolant temperature sensor.
2)Replace the ECM.
3)Replace the engine harness.
