How to Remove and Replace an Oil Level Sensor
Automobiles need engine oil to lubricate the parts that grind together and to reduce heat in the combustion cycle. If a car doesn't have enough oil, the moving parts of its engine will generate more friction, so the engine will overheat or worse-melt. To prevent sudden dips in oil level, cars nowadays are equipped with oil level sensors that warn drivers if the oil level is too low. However, these sensors eventually get damaged after some time. If your car's oil level sensor is not working properly, it has to be replaced ASAP, so you'll always be aware of how much oil your car has. This guide will teach you how you can remove and replace your car's damaged oil level sensor in your own garage.
- New oil level sensor
- Floor jack
- Jack stands
Safety tip: Because engine oil can scald you and cause skin irritation, it's best to wear protective gloves and glasses before replacing the oil level sensor.
Step 1. Raise your car with the floor jack, and support it with jack stands. Once your car is fully supported by the jack stands, roll under it with your creeper.
Step 2. Locate the oil level sensor. Typically, it is located beside the oil pan and has a two-wire wiring harness.
Step 3. Once you located the sensor, pry the tabs off the sensor's wiring harness.
Step 4. Remove the sensor by turning it to the left with your wrench. Then, gently remove it from the oil pan.
Step 5. Fit the new oil level sensor in place. Make sure that it fits right and is screwed on tightly. However, make sure that it's not screwed too tight to avoid damaging the oil pan walls. Then, connect the wiring harness back to the sensor.
Step 6. Remove the jacks to lower your car to the ground. Then, start your engine and check if the oil level sensor is displaying your car's oil level correctly. If it doesn't, repeat all the steps and make sure that all of them are followed properly.
