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 fan control logic can be adjusted with INSITE™ electronic service tool. There are two choices: 12 or 24 volts ON, or 0 volts ON. For proper fan operation, the fan control logic setup with INSITE™ electronic service tool must match the hardware configuration on the vehicle. This fault code is logged when the ECM commands 12 or 24 VDC to the fan control solenoid, but the...
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2451 PID: SPN: 2789 FMI: 0 Turbocharger Turbine Inlet Temperature (Calculated) – Data Valid but Above Normal Operational Range – Moderately Severe Level.

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, calibrate the ECM. The most common cause of this fault code is low boost pressure. Low boost pressure can be caused by several factors; leaking charge air cooler, damaged charge air cooler piping or hose, loose charge air cooler clamps, damaged intake manifold pressure sensor, damaged variable geometry turbocharger, damaged turbocharger control valve, or damaged turbocharger control shutoff valve. This fault code can also be caused by a turbocharger fuel...
PACCAR PX-8 CM2150 (2007-09) Fault Code: 249 PID: 171 SPN: 171 FMI: 3 Ambient Air Temperature Sensor 1 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage detected at ambient air 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 ambient air temperature sensor shares return wires in the engine harness with other sensors. Opens and shorts in the engine harness can cause multiple fault codes to be active. Check active fault codes with multiple counts first. Possible causes: 1)Open return circuit in the harness, connectors, or sensor2)Open signal circuit or shorted to voltage source. Possible repairs: 1)Replace the ambient air temperature sensor.2)Replace the ECM.3)Repair or...
PACCAR PX-8 CM2150 (2007-09) Fault Code: 252 PID: 98 SPN: 98 FMI: 2 Engine Oil Level – Data Erratic, Intermittent, or Incorrect. An intermittent signal is being received from the oil level sensor.

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. Possible causes: 1)The oil level sensor is not receiving power from the ECM. This could be caused by an open circuit in the power supply or low voltage supplied by the primary engine ECM2)Open return circuit on the oil level sensor circuit between the engine ECM and the oil level sensor3)Open or short circuit on the oil level sensor signal circuit between the ECM and oil level...
PACCAR PX-8 CM2150 (2007-09) Fault Code: 253 PID: 98 SPN: 98 FMI: 1 Engine Oil Level – Data Valid But Below Normal Operational Range – Most Severe Level. Very low oil level has been detected by the oil level sensor.

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. If inactive counts of Fault 253 are logged in the ECM, it could be possible that the engine was running or keyed on while tilted at an angle severe enough to cause this fault to be triggered. Possible causes: 1)The engine may not have been filled to proper capacity during the most recent oil change2)External engine oil leaks (oil leaking onto the ground)3)Internal engine oil leaks (oil...
