This little guy measures the temperature of either the engine coolant or sometimes the oil, depending on which one you need. It sends that temperature reading as an electrical signal to the car’s computer – the ECU, or engine control unit. Basically, it's telling the computer how hot things are running. Think of it as a key information source for the computer. The computer uses this temperature data to adjust things like the fuel mixture, ignition timing, and even how the cooling fan operates. It’s a critical part of keeping the engine running smoothly and efficiently. It also plays a role in how your temperature gauge reads on the dashboard, letting you know if things are getting too hot. If this sensor fails, it can cause a lot of problems. The computer might think the engine is cold when it’s actually hot, or vice versa. This can lead to poor fuel economy, rough idling, difficulty starting, and in serious cases, even engine damage. You’ll notice if it’s bad – things will run poorly, your check engine light will probably come on, and you might see inaccurate readings on your temperature gauge. It’s one of those relatively inexpensive parts that can save you a lot of headache and money down the road. You can usually find a good replacement, exactly the one for your car, at places like Fixparts Online. Suitable for every driver: Temperature Sensor (MPN 0281002311) includes a 12-month warranty!
