Reasons for Crankshaft Position Sensor Failure?

[McJourney]

Crankshaft position sensor failures have different causes depending on their types, with the main reasons being damage to the magnetic pulse signal disk or magnetic head. Here is more information about the crankshaft position sensor: 1. The crankshaft position sensor is a crucial component in the centralized control system of fuel-injected engines. If the crankshaft position sensor fails, it will affect the normal operation of the vehicle. 2. The crankshaft position sensor plays a vital role among sensors, as it determines the position of the crankshaft, detects engine speed, and also identifies signals such as the top dead center signals of each cylinder for ignition control and the first cylinder's top dead center signal for sequential fuel injection control. 3. Common symptoms of a faulty crankshaft position sensor include difficulties in normal engine startup, automatic engine stalling upon ignition, engine shaking, white smoke emission, but without significant changes in power performance and normal throttle response.
