Oil Pressure Sensor Circuit

Circuit Description:The oil pressure sensor (OPS) 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 bythe ECM for the engine protection system.

Component Location:M11 - The oil pressure sensor is located on the engine block to the right of the ECM.N14 - The oil pressure sensor is located on the engine block near the pan rail on the fuel pump side of the engine.

Shop Talk:Does the fault occur only in cold weather? If so, allow the oil to warm up and see if the fault goes inactive.
