What is an oil pressure sensor?
The oil pressure sensor is an electrical switch designed to measure accurate, real-time pressure and send a warning signal to your car’s instrument panel when something is wrong.
Your car relies on the right oil pressure to circulate oil throughout the engine. If the pressure drops or is too high, the engine won’t be able to cool itself, or the friction between unlubricated parts can cause significant damage.
Since you can’t visually measure oil pressure, your vehicle’s oil pressure sensor is vital to engine performance and overall engine health.
When should I replace the oil pressure sensor on my car?
Oil pressure sensors are notoriously tricky to diagnose. You may be in need of a replacement if you notice the following common symptoms of a bad oil pressure sensor:
The oil pressure light blinks repeatedly.
The oil warning light is still illuminated after replacing your oil.
The oil pressure gauge displays inaccurate readings.
The check engine light appears.
The engine activates limp mode.
How often should an oil pressure sensor be replaced?
Most vehicles never need a replacement oil pressure sensor, since they generally last the life of the vehicle. You should watch for signs of a faulty oil pressure sensor and take your vehicle to a mechanic when you suspect a replacement is required.
Pro tip: Regular maintenance, like oil changes, can help prevent your oil pressure sensor from failing.
Can I replace my oil pressure sensor myself?
You should only complete an oil pressure sensor replacement at home if you already have the specialized tools and DIY auto repair experience. Most drivers should take their vehicle to a professional mechanic to do the replacement.
