What is the working principle of the camshaft position sensor?
1 Answers
The working principle of the camshaft position sensor: It collects the position signal of the valve camshaft and inputs it to the ECU, enabling the ECU to identify the top dead center of cylinder 1 compression. This facilitates sequential fuel injection control, ignition timing control, and knock control. The camshaft position sensor is a sensing device, also known as a synchronization signal sensor, and serves as a cylinder identification and positioning device. The camshaft position signal it sends to the ECU is the main control signal for ignition. The camshaft position signal is also used to identify the first ignition timing during engine startup. Because the camshaft position sensor can identify which cylinder piston is about to reach top dead center, it is referred to as a cylinder identification sensor.
