CODE

Fault Code: 135

PID: P100

SPN: 100

FMI: 3/3

LAMP: Amber

SRT:

 

REASON

High signal voltage detected at the engine oil pressure circuit.

 

EFFECT

None on performance.

 

 

Circuit Description

The engine control module (ECM) provides a 5 volt supply to the engine oil pressure sensor on the sensor supply circuit. The ECM also provides a ground on the sensor return circuit. The engine oil pressure sensor provides a signal to the ECM on the engine oil pressure sensor signal circuit. This sensor signal voltage changes based on the pressure in the oil rifle. The ECM will detect a low signal voltage at operating conditions when the oil pressure may be slightly lower. The ECM will detect a high signal voltage during high engine speeds or operating conditions when the oil temperature is low.

 

Component Location

The engine oil pressure sensor is located on the outlet of the oil filter head.

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 Engine Control Module (ECM) detected the engine oil pressure signal voltage was out of range high.

 

Action Taken When the Fault Code is Active

The ECM illuminates the amber CHECK ENGINE lamp immediately when the diagnostic runs and fails.

A default value for the engine oil pressure reading is used.

 

Conditions for Clearing the Fault Code

To validate the repair, perform a key cycle, start the engine and let it idle for 1 minute.

The fault code status displayed by the recommended Cumminsg® electronic service tool or equivalent will change to INACTIVE immediately after the diagnostic runs and passes.

The ECM will turn off the amber CHECK ENGINE lamp immediately after the diagnostic runs and passes.

The “Reset All Faults” command in the recommended Cummings® electronic service tool or equivalent can be used to clear active and inactive faults.

 

Shop Talk

The oil pressure sensor shares supply and return wires in the engine harness with other sensors, opens and shorts in the engine harness can cause multiple fault codes to be active. Before troubleshooting Fault Code 135, check for multiple faults.

 

Possible causes of this fault code include:

Open return circuit in the harness, connectors, or sensor

Signal circuit shorted to sensor supply or battery voltage.
