PACCAR PX-6 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.
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 is an information fault code indicating that the engine has been derated for high turbine inlet temperature (exhaust temperature). No troubleshooting is necessary for this fault code. It is only an indicator that the engine power was derated to limit the exhaust temperature.
If the condition continues to exist, Fault Code 2451 will become active.
The engine power output was derated to limit the exhaust temperatures. This is normal operation. No repairs are necessary.
PACCAR PX-6 CM2150 (2007-09) Fault Code: 2345 PID: 103 SPN: 103 FMI: 10 Turbocharger 1 Speed – Abnormal Rate of Change. The turbocharger speed sensor has detected an erroneous speed value.
PACCAR PX-6 CM2150 (2007-09) Fault Code: 2322 PID: SID 064 SPN: 723 FMI: 2 Engine Camshaft Speed/Position Sensor – Data Erratic, Intermittent, or Incorrect. Camshaft engine speed sensor intermittent synchronization.
PACCAR PX-6 CM2150 (2007-09) Fault Code: 2321 PID: 190 SPN: 190 FMI: 2 Engine Crankshaft Speed/Position – Data Erratic, Intermittent, or Incorrect. Crankshaft engine speed sensor intermittent synchronization.
PACCAR PX-6 CM2150 (2007-09) Fault Code: 2311 PID: SID 108 SPN: 633 FMI: 11 Electronic Fuel Injection Control Valve Circuit – Condition Exists. Fuel pump actuator circuit resistance too high or too low.
PACCAR PX-6 CM2150 (2007-09) Fault Code: 2288 PID: 103 SPN: 103 FMI: 0 Turbocharger 1 Speed – Data Valid but Above Normal Operational Range – Least Severe Level. High turbocharger speed has been detected by the ECM.
PACCAR PX-6 CM2150 (2007-09) Fault Code: 2274 PID: 411 SPN: 411 FMI: 4 Exhaust Gas Recirculation Valve Delta Pressure Sensor Circuit – Voltage Below Normal or Shorted to Low Source. Low signal voltage detected at the EGR differential pressure sensor circuit.
