SPN100 FMI3
Oil Pressure Sensor Circuit - Voltage Above Normal, or Shorted to High Source
CODES:
Fault Code: 135
PID(P), SID(S): P100
SPN: 100
FMI: 3
Lamp: Amber
SRT:
REASON: Oil Pressure Sensor Circuit - Voltage Above Normal, or Shorted to High Source. High signal voltage detected at the engine oil pressure circuit.
EFFECT: None on performance. No engine protection for oil pressure.
Circuit Description:
The engine oil pressure sensor is used by the electronic control module (ECM) to monitor the lubricating oil pressure. The ECM monitors the voltage on the signal pin and converts this to a pressure value.
Component Location:
The engine oil pressure sensor is located on the left side of the engine block.
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.
