What is an oil temperature sensor?
The engine oil temperature sensor is an electronic sensor that monitors the temperature of the vehicle’s engine oil and communicates the information with the temperature gauge on your vehicle’s instrument cluster. This system allows you to monitor your oil temperature to avoid your engine overheating.
The oil temperature sensor is typically located on the engine block or the cylinder head.
When should I replace the oil temperature sensor on my car?
You should replace your oil temperature sensor when you notice the following:
Your check engine light has come on.
Oil temperature gauge is inaccurate.
Oil temperature gauge is unresponsive.
Regular oil changes and allowing your car to warm up before driving in the winter are good ways to prolong the life of your oil temperature sensor—and your engine.
How often should an oil temperature sensor be replaced?
There is no mileage or age limit for your vehicle’s oil temperature sensor. Instead, you should be aware of warning signs of a faulty oil temperature sensor and take your vehicle to a mechanic if you suspect you’re in need of a replacement.
Can I replace my oil temperature sensor myself?
Replacing an engine oil temperature sensor requires technical knowledge of your vehicle’s engine and electrical components.
While it is possible to replace the sensor at home, most drivers should leave their oil temperature sensor replacement to a professional.
