Oil Pressure Sensor Circuit
SMALL | MEDIUM | LARGE

Circuit Description

The oil pressure/temperature 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. The oil pressure value is used by the ECM for the engine protection system.

Component Location

The oil pressure/temperature sensor is located on the engine block, below the exhaust manifold and near the oil filter housing.

Shop Talk

  • If Fault Code 143 or 415 is not present, the problem is not related to the engine lubrication system.
  • INSITE™ can be used to monitor the oil pressure signal voltage going into the ECM.
  • Confirm that the correct oil pressure/temperature sensor part number is being used.
  • If Fault Codes 141 and 238 are active, then begin troubleshooting Fault Code 238 first.
