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. This fault code goes active when the engine oil pressure drops below the engine protection limit. Troubleshoot the engine for low oil pressure. 1)If necessary, recalibrate the ECM. PACCAR PX-8 CM2150 (2007-09) Fault Code: 141 PID: 100 SPN: 100 FMI: 4 Engine Oil Rifle Pressure 1 Sensor Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the engine oil pressure circuit. PACCAR PX-8 CM2150 (2007-09) Fault...

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. Before troubleshooting Fault Code 144, check for multiple faults. The engine coolant temperature sensor shares return wires in the engine harness with other sensors. An open return can cause multiple fault codes to be active. Possible causes: 1)Open return circuit in the harness, connectors, or sensor.2)Open signal circuit or shorted to a voltage source. Possible repairs: 1)Replace the engine coolant temperature sensor.2)Replace the ECM.3)Replace the engine harness....

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 harness2)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. PACCAR...

Verify the 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, calibrate the ECM. This fault code indicates that coolant temperature has exceeded the engine protection limits for high coolant temperature. Possible repairs: 1)Replace the engine coolant temperature sensor.2)Replace the ECM.3)Replace the engine harness. 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. PACCAR PX-8 CM2150...
