Camshaft Position Sensor

The camshaft position sensor is a crucial component of the engines electronic control system, used to monitor the rotational position and speed of the camshaft. It transmits data to the Engine Control Unit (ECU) by sensing signal teeth or magnetic markers on the camshaft. Based on the sensor signal, the ECU determines the valve opening and closing timing and, in conjunction with crankshaft position sensor data, precisely controls the fuel injection quantity and ignition timing. This not only ensures smooth engine operation but also improves fuel efficiency and reduces emissions. If the camshaft position sensor fails, the engine may experience problems such as difficulty starting, reduced power, or stalling. Therefore, maintaining its proper function is essential for engine performance.
