Engine Oil Pressure Sensor Circuit Malfunction

What This Means

The engine oil pressure sensor or its circuit is not functioning correctly. While this code relates to the sensor circuit and not necessarily actual oil pressure, low oil pressure is a serious engine-damaging condition.

Common Symptoms

• Oil pressure warning light on
• Incorrect oil pressure gauge reading
• Check engine light on
• Engine noise if actual pressure is low

Common Causes

• Faulty oil pressure sensor/switch
• Wiring damage to sensor
• Low engine oil level
• Oil pump wear
• Clogged oil pickup screen
