This little gasket basically creates a seal. It sits between the oil pressure sensor and the engine block, stopping oil from leaking out where the sensor screws in. It’s a simple part, but it has a critical job. Think of it as part of the engine's circulatory system. The oil pressure sensor tells the computer how much oil is flowing, which is vital for things like the oil light on your dash and making sure the engine is getting properly lubricated. The gasket keeps everything sealed up so that sensor can get an accurate reading. Without a good seal, you’ll have oil leaking, and the sensor won't work right. If this gasket fails, you'll almost certainly develop an oil leak. You’ll notice if you have one, probably as an oil spot on your driveway or a burning oil smell. Beyond the mess and the need to keep your oil topped off, a bad leak can cause a false reading from the sensor – meaning your oil light might come on when it shouldn’t, or worse, not come on when it should. That could lead to serious engine damage. They're cheap and easy to replace, so it's always best to do it when you’re messing with the sensor. You can find them easily enough online, Fixparts Online carries a good selection, but most auto parts stores will have them too. It's a small part that prevents a big headache.
