A camshaft sensor is a device used to monitor the position of the camshaft in an internal combustion engine. It is typically a Hall effect sensor, which means that it generates a voltage when exposed to a magnetic field. The camshaft sensor is used to provide the engine’s electronic control unit (ECU) with information about the position of the camshaft, which is necessary for the ECU to control the timing of the engine’s valves.
A faulty camshaft sensor can cause a variety of problems, including:
