This MEAT & DORIA Camshaft Position Sensor, part number 87443, is designed to precisely monitor the position of the camshaft. Accurate camshaft position data is crucial for the engine control unit (ECU) to manage ignition timing and fuel injection. This allows for smooth engine operation, improved power delivery, and reduced emissions. Replacing a faulty sensor can resolve issues such as rough idling, poor acceleration, and check engine lights.
