Cummins ISB4.5 CM2150 Fault Code: 435 PID: 100 SPN: 100 FMI: 2 Engine Oil Rifle Pressure – Data Erratic, Intermittent, or Incorrect.
Posted by PerDiezel Solutions on
Circuit DescriptionThe engine oil pressure switch is used by the electric control module (ECM) to monitor the lubricating oil pressure. The oil pressure switch is normally closed when the engine is not operating and open when the engine is in operation and oil pressure is present. Component LocationThe location of the oil pressure switch varies by engine model. Conditions for Running the DiagnosticsThis diagnostic runs when the keyswitch is turned ON and before engine speed is detected. The diagnostic only runs once per trip. Conditions for Setting the Fault CodesThe ECM detects that the engine oil pressure switch is indicating...

Circuit DescriptionThe engine oil pressure sensor is used by the electronic control module (ECM) to monitor the lubricating oil pressure. If the oil pressure drops below the engine protection limit, the sensor will open and cause Fault Code 435 to log. The oil pressure sensor is normally closed when the engine is not operating and open when oil pressure is present. Conditions for Running the DiagnosticsThis diagnostic runs when the keyswitch is turned ON and before engine speed is detected. The diagnostic only runs once per trip. Conditions for Setting the Fault CodesThis fault code is logged when an open...
Cummins ISB4.5 CM2150 Fault Code: 436 PID: 111 SPN: 105 FMI: 2 Intake Manifold 1 Temperature – Data Erratic, Intermittent, or Incorrect.
Posted by PerDiezel Solutions on
Circuit DescriptionThe intake manifold 1 temperature sensor is a variable resistor sensor and is used to measure the temperature of the air entering the intake manifold of the engine. The engine intake manifold temperature value is used by the electronic control module (ECM) for the engine protection system and engine emission control. The ECM supplies 5 volts to the intake manifold temperature signal circuit, and monitors the change in voltage caused by changes in the resistance of the sensor to determine the intake manifold temperature. When the intake air is cold, the sensor (or thermistor) resistance is high. The ECM...
Cummins ISB4.5 CM2150 Fault Code: 441 PID: 168 SPN: 168 FMI: 1 Battery 1 Voltage – Data Valid but Below Normal Operating Range – Moderately Severe Level.
Posted by PerDiezel Solutions on
Circuit DescriptionThe engine control module (ECM) receives constant voltage from the batteries through the unswitched battery wires that are connected directly to the positive (+) battery post. There is one 30-ampere fuse in the unswitched battery wires to protect the original equipment manufacturer (OEM) harness. The ECM receives switched battery input through the vehicle keyswitch wire when the vehicle keyswitch is turned ON. The battery return wires are connected directly to the negative (-) battery post. Component LocationThe ECM is connected to the battery by the OEM harness. This direct link provides a constant power supply for the ECM. The...
