What is an Engine Oil Level Sensor?

An engine oil level sensor is a sensor. For the oil level. In your engine. Put another way, it senses the level of the engine oil. That’s it. Easy peasy.

So, why exactly do you need this component in your car? The short answer is chances are, you’re not regularly checking your car’s oil level. But if you want the longer, less insulting answer, so you can feel better about yourself, then read on.

Look at it this way. You barely keep track of how much water you drink daily. Why would you trust yourself to check the level of oil in your engine? Sorry, I said we were done being insulting. Let’s try again.

Engine oil is the lifeblood of the engine which means you have to keep enough of it in the engine to keep it running. Without enough oil, the engine doesn’t have proper lubrication, and hopefully I don’t have to explain to you what happens when the moving parts of your engine aren’t lubricated. You can figure that one out on your own. Hopefully not by experience.

That’s where the engine oil level sensor comes in. Gone are the days where we have to pop the hood to know where our levels are at. An engine oil sensor is literally just a sensor that detects how much oil is left in the oil pan, and relays that information to you while you sit in the car.

Engine oil level sensors usually have a long shelf life, but like most parts of your car, they can eventually die. And if you think that’s no big deal because you’ll just check your oil manually (riiiiight), you should know that the sensor actually affects other parts of your car indirectly. So… it’s kind of a big deal.

In theory, replacing the engine oil level sensor is an easy task, but it depends on the location. And that’s going to depend on the year, make, and model of your car. While some might be intuitively placed and easy to access, others might live in a mirror maze of madness. Either way, when it’s dead, it ain’t gonna fix itself.

Symptoms of a failing Engine Oil Level Sensor

Motor oil warning lights

Is this light supposed to be on? An engine oil light could point to bad engine oil level sensor. Or it could mean that your car is low on motor oil. Look, I know warning lights are easy to ignore, but let’s get in the habit of paying attention tot hem, shall we? When those lights tell you that your car is running low on engine oil, check the oil level manually. If you are low, then it’s time for new oil. If you’re not low, then it’s time for a new sensor.

Bizarre oil level readings

Whoa, that can’t be right… If you notice your oil level readings aren’t making sense, manually check if your oil levels are where they should be. This is similar to what we just talked about with warning lights, so we’ll be brief. A busted-up engine oil level sensor might be a bit erratic. You might notice the sensor suggesting you’re low on oil one minute, and then have an ample amount later. That’s a bad sign. Or, as previously mentioned, you might notice that the sensor level and the actual level aren’t lined up, and that’s a sure sign.

Car isn’t driving well

Uh oh. Why is the car acting up? If you notice the ride is a little rough, noisy, or otherwise funky, it may be because the engine oil level is low. If the oil level is low, but the engine oil level sensor isn’t warning you about it, then…well, you can put two and two together here. I hope.

How urgent is an Engine Oil Level Sensor replacement?

If all you did was skim the upper portion of this article, then all you need to know is that your engine oil level sensor is pretty important. While you can check your oil level manually, do you really trust yourself to do so? And oil is the lifeblood of your engine and keeps it running smoothly. So, a broken sensor could lead to low oil levels which in turn could lead to engine damage. If you’re experiencing any of the symptoms above, get your engine oil level sensor replaced asap.
