PACCAR PX-8 CM2150 (2007-09) Fault Code: 2367 PID: SID 80 SPN: 1073 FMI: 3 Engine Brake Actuator Driver Output 2 Circuit – Voltage Above Normal or Shorted to High Source.

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 circuit in the engine harness, brake harness, or engine brake solenoids
2)Short to voltage source in the engine harness
3)Damaged ECM.

Possible repairs:

1)Replace the engine brake solenoid.
2)Replace the ECM.
3)Repair or replace the engine harness.

PACCAR PX-8 CM2150 (2007-09) Fault Code: 2363 PID: SID 029 SPN: 1073 FMI: 4 Engine Brake Actuator Driver Output 2 Circuit – Voltage Below Normal or Shorted to Low Source. Low voltage detected at the engine brake solenoid number 2 signal circuit.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2359 PID: 411 SPN: 411 FMI: 0 Exhaust Gas Recirculation Valve Differential Pressure – Data Valid But Above Normal Operating Range – Moderately Severe Level. The EGR differential pressure sensor has detected high EGR gas flow, or the EGR differential pressure reading is not valid for engine operating conditions.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2357 PID: SID 146 SPN: 2791 FMI: 7 EGR Valve Control Circuit – Mechanical System Not Responding Properly or Out of Adjustment. The EGR motor has exceeded the duty cycle limit, indicating a stuck open EGR valve.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2351 PID: SID 146 SPN: 2791 FMI: 4 EGR Valve Control Circuit – Voltage Below Normal or Shorted to Low Source. Motor terminal or motor coil short circuit to ground or power supply has been detected by the ECM.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2349 PID: SID 146 SPN: 2791 FMI: 5 EGR Valve Control Circuit – Current Below Normal or Open Circuit. Motor terminal or motor coil open circuit has been detected by the ECM.
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2347 PID: SPN: 2790 FMI: 0 Turbocharger Compressor Outlet Temperature (Calculated) – Data Valid but Above Normal Operational Range – Least Severe Level. High turbocharger compressor outlet air temperature has been calculated by the electronic control module (ECM).
