Engine Oil Pressure Sensor/Switch High

The Engine Control Module (ECM) continuously monitors the engine oil pressure. The Engine Oil Pressure (EOP) Sensor/Switch sends a voltage signal to the ECM when the engine is running. The ECM monitor the signal circuit of the EOP sensor to determine the engine sensor voltage is within the normal operation range.

Low oil level or motor mechanical fault
Faulty Oil Pressure sensor
Oil Pressure Sensor harness is open or shorted
Oil Pressure Sensor circuit poor electrical connection

Check engine light
Oil pressure warning light ON
