The synchronous signal of the engine is the basis of its working sequence.The components of the camshaft signal include the camshaft sensor signal plate,camshaft sensor,camshaft sensor gap,wiring harness and connectors,ECU and so on.When there is a camshaft signal error,it should be checked one by one.For the engine with timing chain system,the starting time of the timing chain system is long,and the angle deviation of the signal plateis large due to the slack of the timing chain,which leads to the difficulty of starting the camshaft signal when the fault is serious.In the design of the engine with timing chain system,the check structure should be considered to advance locking.Or use a signal disk with a large fault tolerance Angle.
