This little guy’s job is pretty simple, really. It constantly monitors the temperature of the engine coolant – that’s the fluid running through your engine to keep it from overheating. It sends a signal to the engine’s computer, letting it know how warm or cold things are. It’s an electrical component, so it’s all about sending that accurate temperature reading. Think of it like this, the computer needs to know how hot the engine is to make all sorts of decisions. It controls things like how much fuel to inject, whether to turn on the radiator fans, and even how the engine timing works. Basically, it’s telling the computer what’s going on inside the engine, so the computer can keep everything running smoothly and efficiently. It acts like a shield, preventing damage from overheating or running too lean. If this sensor fails, things can get messy quickly. You might notice your engine running poorly, getting worse gas mileage, or even overheating. You’ll notice if your temperature gauge is reading incorrectly, or if the engine is having trouble starting. Sometimes it can even put the engine into limp mode to protect it. It’s a relatively inexpensive part, and fixing it before it causes bigger problems is always the smart move. You can find a replacement coolant temperature sensor pretty easily – places like Fixparts Online usually have them in stock. Getting a new one and replacing it is a lot cheaper than dealing with an overheated engine. Buy risk-free: Coolant Temperature Sensor (MPN 45440) is covered by a 3 year manufacturer guarantee!
