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. High voltage on the (+) 5 volt supply wire can be caused by a short to battery voltage in the engine harness or connectors, or a damaged ECM. Possible repairs: 1)Replace the ECM.2)Repair or replace the engine harness. PACCAR PX-8 CM2150 (2007-09) Fault Code: 238 PID: SID 232 SPN: 3511 FMI: 4 Sensor Supply 3 Circuit – Voltage Below Normal or Shorted to Low Source. Low voltage...

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. There are multiple types of vehicle speed sensors. Various types include magnetic pickup, data link, digital, and tachograph. Refer to the OEM for the specific type installed on the vehicle. This fault is set active when the ECM loses a vehicle speed signal when other engine conditions indicate the vehicle is moving. The fault can also become active if there is a series of clutch, service brake....

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. Verify that the feature settings for the vehicle speed sensor anti-tampering (Fault Code 242), application type and automatic transmission are set correctly. If any of these are set incorrectly for the specific vehicle and application, Fault Code 242 could occur erroneously. Driving techniques such as driving for extended periods of time in lower gears can log Fault Code 242. Fault Code 242 can be logged if the...

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. This fault code goes active when the coolant level inside the radiator top tank or surge tank drops below the sensor level. Fill the top tank with coolant. Possible repairs: 1)Add coolant to the engine. PACCAR PX-8 CM2150 (2007-09) Fault Code: 2387 PID: SID 027 SPN: 641 FMI: 7 VGT Actuator Driver Circuit (Motor) – Mechanical System Not Responding Properly or Out of Adjustment. The smart VGT...

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 is logged when one of the following error conditions exists. 1)If the turbocharger actuator has just been replaced and this fault code is active, this usually indicates that the turbocharger actuator has not been installed correctly. The gear alignment between the actuator and the turbocharger housing is misaligned.2)Foreign material in the VGT turbocharger can prevent the sliding nozzle from moving to the desired position at key-on. The...
