This little guy basically measures the temperature of things – usually either the engine coolant or the air coming into the engine. It sends that information as an electrical signal to the car’s computer. It's a pretty simple job, really – just reporting how hot or cold something is. Different sensors handle different areas, so there’s often more than one in your engine. That temperature reading is hugely important. The car’s computer uses it to adjust how much fuel to inject, when to turn on the cooling fan, and even how the ignition timing works. It’s kind of like the brain getting information about whether to put on a jacket or turn on the AC. If the sensor isn’t accurate, the computer makes bad decisions. It influences a lot of how smoothly your engine runs, and even impacts things like fuel economy and emissions. If this sensor goes bad, you’ll probably notice it. You might see your temperature gauge acting strangely, the engine running roughly, or even a check engine light. Sometimes, a bad sensor will make the engine run rich – meaning it’s getting too much fuel – and that can foul spark plugs or damage the catalytic converter over time. It’s one of those parts that doesn't seem like much, but plays a critical role. You can find these pretty easily, we stock a lot of them, and places like Fixparts Online will have options too. Ignoring it usually leads to bigger problems down the road, so it's best to replace it when it's showing signs of failing.
