What Are the Causes of Crankshaft Position Sensor Failure?

[VanLincoln]

Crankshaft position sensor failure is caused by damage to the magnetic pulse signal disc or magnetic head. The crankshaft position sensor is a critical component in the centralized control system of an electronic fuel injection engine. If the crankshaft position sensor malfunctions, it can affect the normal operation of the vehicle. Common symptoms of crankshaft position sensor failure include difficulty starting the engine or the engine stalling shortly after starting. The crankshaft position sensor plays a vital role in determining the position of the crankshaft, monitoring engine speed, and detecting signals such as the top dead center (TDC) signals for each cylinder used in ignition control and the first cylinder TDC signal for sequential fuel injection control. The crankshaft position sensor typically works in conjunction with the camshaft position sensor to determine the basic ignition timing.
