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 Code 471 are logged in the ECM, it can be possible that the engine was running or keyed on while tilted at an angle severe enough to cause this fault to be triggered. Other causes of Fault Code 471 can include: 1)The engine was not filled to proper capacity during the most recent oil change2)External engine oil leaks (oil leaking onto the...
PACCAR PX-6 CM2150 (2007-09) Fault Code: 488 PID: 105 SPN: 105 FMI: 16 Intake Manifold 1 Temperature – 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, recalibrate the ECM. The intake manifold 1 temperature sensor measures the temperature of the charge-air as it passes through the intake manifold. Possible causes of this fault code include: 1)Plugged charge air cooler fins2)Restricted airflow through the charge air cooler3)An undersized charge air cooler4)High turbocharger compressor outlet temperature. Possible repairs: 1)Replace the intake manifold temperature sensor. PACCAR PX-6 CM2150 (2007-09) Fault Code: 471 PID: 98 SPN: 98 FMI: 1 Engine...
PACCAR PX-6 CM2150 (2007-09) Fault Code: 499 PID: 98 SPN: 98 FMI: 4 Engine Oil Level Sensor Circuit – Voltage Below Normal or Shorted to Low Source. The engine oil level sensor has detected an internal failure.

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)Open or short circuit internally to the oil level sensor2)A malfunctioning oil level sensor. Possible repairs: 1)Replace the oil level sensor.2)The removal and installation of the connector may correct the problem. PACCAR PX-6 CM2150 (2007-09) Fault Code: 488 PID: 105 SPN: 105 FMI: 16 Intake Manifold 1 Temperature – Data Valid but Above Normal Operational Range – Moderately Severe Level. Intake manifold air temperature signal...
PACCAR PX-6 CM2150 (2007-09) Fault Code: 528 PID: 93 SPN: 93 FMI: 2 Auxiliary Alternate Torque Validation Switch – Data Erratic, Intermittent, or Incorrect. An error has been detected in the alternate torque switch 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 switch can be monitored for proper operation with INSITE™ electronic service tool. If the switch is changing state correctly on the service tool, then the problem does not lie in the switch circuit. The 3-position switch has three states: 1)Position 1 – open2)Position 2 – closed3)Position 3 – 1500 ohm resistance. The 2-position switch has two states: 1)Position 1 – open2)Position 2 – closed. Possible repairs:...
PACCAR PX-6 CM2150 (2007-09) Fault Code: 529 PID: SID 051 SPN: 703 FMI: 3 Auxiliary Input/Output 3 Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage has been detected at the auxiliary input/output 3 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 ECM monitors the voltage level on this circuit. When the ECM commands the OEM output signal low, it expects the voltage level to be approximately 0-VDC. If it detects a high voltage, this fault is recorded. If Fault Code 529 is still active after completing the following troubleshooting steps, refer to the OEM troubleshooting and repair manual for procedures to check the OEM output device for...
