PACCAR PX-9 CM2350 (2013-17) Fault Code:1429 PID: SPN:4187 FMI:31 High Engine Temperature (HET) Shutdown Relay Driver Diagnostic Has Detected an Error – Condition Exists
Posted by Diezel Solutions on
Reason:High Engine Temperature (HET) Shutdown Relay Driver Diagnostic Has Dectected An Error – Condition Exists Effect:The high engine temperature shutdown lamp will not turn on. Circuit Description:The high engine temperature shutdown lamp will indicate when the engine has reached a most severe level high coolant or intake manifold temperature. Fault Code 151 or 155 will trigger the high engine temperature shutdown lamp. Component Location:Refer to the OEM service manual for lamp location Conditions for Running the Diagnostics:This diagnostic runs continuously when the keyswitch is in the ON position or when the engine is running. Conditions for Setting the Fault Codes:The...
PACCAR PX-9 CM2350 (2013-17) Fault Code:143 PID:100 SPN:100 FMI:1 Engine Oil Rifle Pressure – Data Valid But Below Normal Operational Range – Moderately Severe Level
Posted by Diezel Solutions on
Reason:Engine Oil Rifle Pressure – Data Valid But Below Normal Operational Range – Moderately Severe Level. Engine oil pressure signal indicates engine oil pressure is below the engine protection warning limit. Effect:Possible reduced engine performance. Circuit Description:An engine oil pressure switch or oil pressure sensor is used by the engine control module (ECM) to monitor the lubricating oil pressure. For engines with an oil pressure switch, the switch is normally closed when the engine is not running and open when oil pressure is present. For engines with an oil pressure sensor, the ECM will detect a low signal voltage at...

PACCAR PX-9 CM2350 (2013-17) Fault Code:144 PID:110 SPN:110 FMI:3 Engine Coolant Temperature 1 Sensor Circuit – Voltage Above Normal or Shorted to High Source
Posted by Diezel Solutions on
Reason:Engine Coolant Temperature 1 Sensor Circuit – Voltage Above Normal or Shorted to High Source. High signal voltage or open circuit detected at engine coolant temperature circuit. Effect:Fan will stay ON if controlled by the engine control module (ECM). Circuit Description:The coolant temperature sensor is a variable resistor sensor and is used to measure the temperature of the coolant of the engine. The engine control module (ECM) supplies 5 volts to the coolant temperature signal circuit. The ECM monitors the change in voltage caused by changes in the resistance of the sensor to determine the coolant temperature. Component Location:The engine...
