You always know when you’re hungry, right? And I’m pretty sure when you’re hungry, you’re not happy. That’s what they call getting ‘hangry’. Hey, it happens to the best of us. So, your car is similar. Oil isn’t food for your car, but rather, lubricant, but your car still needs a certain amount of it to stay happy. And when it doesn’t have enough oil, it will get hangry. And just as your grumpy comments and rumbling stomach let the world know that you need food, your car will often let you know when it needs oil. One of the ways it lets you know is through the oil pressure sensor. When the engine is running, the oil pressure sensor checks the pressure of the oil as it travels through the system. If you have adequate levels of oil, then the pressure will come back with standard readings, and your car won’t ever let you know about it. But if you’re running short on oil, the sensor will register an insufficient amount of pressure. When that happens, your car will let you know, through a dashboard indicator, that there’s not enough oil in the system. Listen to your car. Knowing when there’s an issue with oil pressure can save you a lot of money if acted on. Not all cars have oil pressure sensors, but the ones that do usually have quite durable sensors. But they can still die and need replacement.
So, there are two important things to note here. The first is that you really need to break your habit of ignoring your car’s warning lights. I know that they look insignificant, but they’re important. The second thing is that your oil pressure light will come on when you have low oil pressure. Usually that’s the result of a functioning oil pressure sensor, not a broken one. But if you find the oil pressure light is up to some shenanigans - coming on and then turning off, and then coming back on, or perhaps blinking - then it may be due to a sensor that is faulty, and spazzing its way to an untimely death. On that note . . .
When your oil pressure light illuminates, it likely means that the oil pressure in your car is low. But not always. Sometimes the sensor is just out to lunch. A bad oil pressure sensor can also cause the oil pressure gauge (if your car is so equipped) to read too high or too low.
Uh oh. Why is the car acting up? It shouldn’t do that, right? If you notice the ride is a little rough, noisy, or otherwise, it may be because the engine oil pressure is low. And if you notice those symptoms, and there isn’t any oil pressure light illuminated, then you might have a faulty oil pressure sensor on your hands.Get a Quote 1-Year | 12,000-Mile Warranty
The oil pressure is directly related to the performance and health of your car. It’s nothing to take lightly. If you’re experiencing any of the symptoms above, it’s time to get the sensor replaced.
