This TOPRAN camshaft position sensor, part number 410 405, is designed to precisely monitor the rotational 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 camshaft position sensor can resolve issues such as rough idling, poor acceleration, engine misfires, and the check engine light illuminating.
