This component, known as the Camshaft Position Sensor ( CMP ), is a precision electronic part in the JAC GS3 engine. Its primary function is to determine the position and rotational speed of the camshaft (valve shaft). The sensor sends a precise signal to the engine control unit (ECU), which compares it to the signal from the crankshaft position sensor. This synchronization is crucial for the ECU to accurately determine the timing of the engine valves opening and closing , ensuring proper combustion efficiency.
If you experience difficulty starting the engine (especially when trying to start the car more than once), feel a significant engine misfire and loss of power, or the Check Engine Light comes on with fault codes indicating incorrect synchronization, this often indicates a faulty camshaft sensor.
⚠️ Important Notice: Please make sure the part matches your vehicle's chassis number before purchasing the product or after ordering.
