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.
1)A short circuit to ground in the engine harness, connectors, or engine brake solenoids.
1)Repair or replace the engine brake harness.
2)Repair or replace the engine harness.
3)Replace the engine brake solenoid.
4)Replace the ECM.
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).
PACCAR PX-8 CM2150 (2007-09) Fault Code: 2346 PID: SPN: 2789 0 Turbocharger Turbine Inlet Temperature (Calculated) – Data Valid but Above Normal Operational Range – Least Severe Level. Turbocharger turbine inlet temperature has exceeded the engine protection limit.
