This little guy basically listens for engine knock, or pinging. That’s an abnormal combustion happening inside the engine. It’s a type of sensor that picks up vibrations caused by that knock – think of it like a really sensitive microphone inside your engine. It doesn't stop the knock, it just detects it and sends a signal to the engine computer. The engine computer uses that signal from the knock sensor to adjust the engine timing. If it hears knock, it will slightly retard the timing—basically tell the engine to fire a tiny bit later. That helps reduce the knock and prevents damage. It's part of a feedback loop—the sensor tells the computer something’s off, and the computer makes a small adjustment to fix it. You’ll notice if a knock sensor goes bad because your engine might run rough, the check engine light will probably come on, and you could lose power or fuel economy. Sometimes it just feels like the engine isn’t running as smoothly as it should. It’s important because engine knock can seriously damage your engine over time. It’s like hitting the pistons with a hammer with each combustion. The knock sensor is really acting like a shield, preventing that damage by letting the computer make those adjustments. Ignoring it can lead to expensive repairs down the road – things like damaged pistons, connecting rods, even cylinder heads. You can find these pretty easily, Fixparts Online has a good selection, but it's something you want to address when it starts acting up.
