If you’ve recently purchased or have owned a car, chances are you already know how to check the oil level since that’s one of the most common causes of engine damage. However, you might not be as familiar with your car’s oil pressure sensor or even what it does. For example, suppose your oil pressure gauge isn’t working correctly, and you’re getting false readings. In that case, you won’t know if your car’s oil pressure is sufficient for driving. Read on to learn about oil pressure sensors and what to do if yours fails.
What Does the Oil Pressure Sensor Do?
The oil pressure sensor is a vital component that reads the pressure with which oil is circulated through the engine. The proper flow of oil through the engine is critical to keep the engine’s internal parts from overheating caused by excessive friction. The oil pressure sensor will display a warning light if the oil pressure is too low, giving you enough time to shut the engine off before damaging the internal components. On many cars, the oil pressure sensor gives readings to an oil pressure gauge mounted on the car’s gauge cluster so you can monitor oil pressure regularly.
What are the Signs of a Failing Oil Pressure Sensor?
If the car’s oil pressure sensor is going bad, you may notice the oil pressure warning light come on or blink intermittently. This is a severe issue that a mechanic should diagnose at once. In addition, most modern cars’ engine control units will also give an error code if the oil pressure sensor isn’t working correctly. Finally, you will notice inaccurate oil pressure readings on the gauge. If you see abnormally high or low readings on the gauge but your car is running fine, the oil pressure sensor may be failing.
What to do About a Failing Oil Pressure Sensor?
Fortunately, oil pressure sensors are typically durable and will last the car’s life. However, as with any automotive component, they can wear out and fail over time. Suppose your mechanic determines the oil pressure sensor is bad. In that case, he will replace it, typically a simple repair that won’t be very costly.
If you suspect that something is amiss with your car’s oil pressure, don’t wait to get it diagnosed by your mechanic. Even if you are confident that the oil pressure sensor is bad, you should get it replaced because if you don’t, you won’t be alerted if there is a problem with your car’s oil pressure. See your auto care specialist immediately if you notice any of the signs of a failing oil pressure sensor.
