This little guy basically measures the temperature of different things – usually coolant, sometimes oil, and even occasionally air intake. It turns that temperature reading into an electrical signal your car’s computer can understand. Different sensors handle different areas, so there’s usually more than one in a vehicle. The computer uses that temperature info for a whole bunch of things. Primarily, it adjusts how much fuel the engine gets. Too cold and it needs more fuel to start and run right. Too hot, and it needs less to avoid damaging things. It also controls the cooling fan, making sure the engine doesn't overheat. Basically, it's a key piece of the puzzle for keeping everything running smoothly and efficiently. It’ll tell the computer if the engine is at operating temperature so things like emissions controls work properly too. If this sensor goes bad, a lot of things can happen. You might notice your fuel economy drop because the computer isn’t getting accurate information. You'll likely see the temperature gauge acting strangely – reading high or low, or even fluctuating wildly. The check engine light will almost certainly come on. In some cases, if it’s a critical sensor and the computer thinks the engine is cold when it’s not, it could run way too rich, potentially damaging the catalytic converter. It really acts like a shield, protecting more expensive parts. You’ll notice if it fails because your car won’t run quite right. You can find these pretty easily online, Fixparts Online is a good source, and they’re usually not too difficult to replace if you’re comfortable doing a little DIY.
