What is the Oil Pressure Sensor?
Oil is very important for your engine – you require enough oil to lubricate and lower friction throughout the engine. There’s no way to physically know how much oil is being pumped through your engine, so your vehicle’s computer depends on the oil pressure sensor to know the flow.The oil pressure sensor is a basic electrical switch that offers information to the instrument cluster’s oil pressure gauge with the accurate real-time pressure. When the pressure gets too low, not enough oil is being pumped through the engine to lubricate and cool parts. When pressure goes below a threshold set by the automaker, the engine oil light on the vehicle’s dashboard illuminates, signaling you that driving could get dangerous.
Bear in mind:
- There is no way to visually know the operating condition of your oil pressure sensor.
- If the sensor fails, it is not possible to know whether there is sufficient oil flow/pressure to lubricate and protect your engine.
- If your oil pressure sensor fails, it should be changed immediately.
How it’s done:
- The car is raised and supported on jack stands and tire is removed
- The defective oil pressure sensor is taken out
- The new oil pressure sensor is fixed
- The engine is started and oil pressure is inspected then the vehicle is taken off the jack stands
- The car is road tested for proper operation
Your vehicle’s oil pressure sensor is an electrical part, and can be subjected to a number of problems, including wiring damage. If you feel there exist damage to the sensor, or have observed your oil light come on, have it checked and diagnosed by a qualified mechanic.
What common symptoms show you may need to change the Oil Pressure sensor?
- Oil pressure light is on
- Oil pressure light comes on and off (can imply several potential problems)
- Depending on your make and model, you may have an oil pressure gauge that shows pressure in PSI. Note any drops below normal working pressure.
How vital is this service?
It is greatly vital that your engine oil pressure be constantly monitored for potentially dangerous conditions. If your oil pressure sensor isn’t functioning properly, it cannot perform its job, and must be changed.
