The reason and solution of lack of camshaft signal are introduced.
1. The lack of signal from camshaft position sensor will affect the starting of the car. When the engine starts and ignits, it ignits according to the signal from camshaft position sensor;
2. Therefore, the signal loss of the camshaft position sensor leads to the engine firing disorder and cannot start;
3. Solution: Use the decoder to check whether the signal of the camshaft position sensor is correct. If it is incorrect, replace the camshaft position sensor and conduct circuit detection.
