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, recalibrate the ECM. The EGR 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)An open return circuit in the harness, connectors or sensor2)An open signal circuit or shorted to a voltage source. Possible repairs: 1)Replace the EGR temperature sensor.2)Replace the ECM.3)Repair or replace the engine harness. PACCAR PX-8 CM2150 (2007-09) Fault Code: 2374 PID: 131 SPN:...
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2376 PID: 412 SPN: 412 FMI: 4 Exhaust Gas Recirculation Temperature Sensor Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at EGR 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 ECM monitors the voltage level on this circuit. When the ECM commands the fan 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 2377 is still active after completing the following troubleshooting steps, consult the OEM troubleshooting and repair manual for procedures to check the fan clutch device for an open...
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 detected on the +5 volt sensor supply circuit to the engine speed 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. The ECM monitors the voltage level on the engine speed sensor +5 volt supply circuit. If the voltage falls below a limit which can be calibrated, then this fault is recorded. Possible causes: 1)Short circuit to ground in the engine harness, sensor, or ECM. Possible repairs: 1)Replace the engine speed sensor.2)Replace the ECM.3)Repair or replace the engine harness. PACCAR PX-8 CM2150 (2007-09) Fault Code: 234 PID: 190...
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.

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. 1)This fault code is set when the actual VGT actuator position does not meet the commanded position for more than 10 seconds.2)Large boost pressure leaks can also cause this fault code. The aftertreatment system must be inspected after making the appropriate repair outlined in this fault code troubleshooting tree. Progressive damage to the aftertreatment system can possibly have occurred. Perform the aftertreatment initial check procedure to test for a damaged...
