Car Auto Engine Oil Pressure Switch Accessory Part 37240-PHM-003
- An engine oil pressure switch is used to maintain power to the engine, and the vehicles.
- Once the engine is running, and the oil pressure is up, power is routed through the oil pressure switch and sensor unit.
- This is done to ensure the engine is not run without oil. The switch will not close, and the vehicle will not stay running.
- This is Non-OEM product. Accessory Only!
