Cummins ISB4.5 CM2150 Fault Code: 498 PID: 98 SPN: 98 FMI: 3 Engine Oil Level Sensor Circuit – Voltage Above Normal or Shorted to High Source.
Posted by PerDiezel Solutions on
Circuit DescriptionThe oil level sensor will monitor the oil fluid level in the oil pan at key-on. The oil level sensor will not monitor the oil level after the engine is started or when the engine speed is greater than 0 rpm. During the engine key-on, if the oil level sensor detects a critical low oil level, the amber CHECK ENGINE light will blink for 30 seconds and a fault code will be logged. If an operator observes a blinking amber CHECK ENGINE light at key-on, the operator must check the engine oil level with the manual dipstick. The oil...

Circuit DescriptionThe ECM provides a signal to the original equipment manufacturer (OEM) output control circuit to turn the OEM supplied accessory on and off. The OEM output control circuit varies by OEM. Certain OEMs can use a circuit return that is wired to the ECM or goes to the engine block or chassis ground. Component LocationThe output control circuit driver is an OEM device and the location of the circuit driver is dependant upon the OEM. Refer to the OEM troubleshooting and repair manual. Shop TalkThe ECM monitors the voltage level on this circuit. When the ECM commands the OEM...

Circuit DescriptionThe intake manifold pressure sensor is used by the engine control module (ECM) to monitor the engine intake manifold pressure. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the keyswitch is in the ON position. Conditions for Setting the Fault CodesThis fault code becomes active when the intake manifold pressure exceeds the maximum pressure limit for a given engine rating. Action Taken When the Fault Code is ActiveThe ECM illuminates the amber CHECK ENGINE light immediately when the diagnostic runs and fails. Conditions for Clearing the Fault Code-To validate the repair, start the engine and let it idle...

Circuit DescriptionThe engine control module (ECM) monitors engine operating conditions, including the reading of rail fuel pressure, and changes the flow command to either increase (Open the fuel pump actuator) or decrease (Close the fuel pump actuator) the fuel supply to the high-pressure pump. Component LocationThe fuel pump actuator is installed in the adapter on the back of the high-pressure fuel pump. Conditions for Running the DiagnosticsThis diagnostic runs continuously when the engine is running. Conditions for Setting the Fault CodesThe ECM has detected that the fuel rail pressure reading has exceeded the recommended operating limits. Action Taken When the...
