This sensor basically keeps track of where the crankshaft is in the engine’s rotation. It’s always watching, measuring how far the crankshaft has turned. It sends that information as an electrical signal back to the engine control unit – the computer that runs everything. It doesn’t make anything happen, it just reports what is happening. Think of it like this: the crankshaft is the main rotating part of the engine, and this sensor is its dedicated observer. The engine control unit uses this info for a bunch of stuff. Primarily, it needs it to time the fuel injection and the spark for the ignition. Without knowing where the crankshaft is, the computer can't figure out when to spray fuel into the cylinders or when to fire the spark plugs. It's crucial for getting the whole combustion process right. It also plays a role in things like cruise control and the tachometer, but those are secondary. If this sensor goes bad, things will definitely start to run rough. You’ll likely experience hard starting, stalling, a check engine light, and generally poor engine performance. Sometimes, the engine just won’t start at all. It acts like a shield, protecting the computer from having to guess when things are happening inside the engine. Without accurate information, the computer can’t do its job. You’ll notice if it's failing because the engine timing will be way off. A lot of people find these parts easily enough on sites like Fixparts Online, and honestly, it's one of those things that’s best to get sorted out sooner rather than later. Ignoring it will only lead to bigger, more expensive problems. We stand behind our products: Crankshaft Position Sensor (MPN 33103553) has a 12-month warranty!
