The camshaft position sensor is a device that looks over the camshafts position and speed. The engine control module uses the information to regulate the fuel injectors and injection timing of the vehicle.
Camshaft position sensor conceptA camshaft position sensor is accompanied by an ECM that uses the data it receives to control the fuel that enters the combustion chamber. When the process of igniting the air/fuel mixture is exact, the engines power increases and emissions decrease. Nowadays, more cars are equipped with numerous sensors that are crucial to control the engine and provide quality vehicle function.
The auto-start/stop on modern cars is determined by the camshaft position sensor. It determines which cylinder is in the power stroke compared to the crankshaft position. As soon as you step on the accelerator the fuel and spark will be directed to start the engine.
Common issues with a camshaft position sensorA faulty camshaft position sensor can lead to stalling, poor engine performance, and bad fuel mileage.
