If there is a circuit fault in the crankshaft position sensor, it is first necessary to measure whether the circuit of the crankshaft position sensor is smooth. If there is nothing wrong with the circuit, the crankshaft position sensor needs to be replaced.
The function of the shaft position sensor is to determine the position of the crankshaft, that is, the rotation angle of the crankshaft. It usually determines the basic ignition time together with the camshaft position sensor.
