What are the reasons for frequent failure of the crankshaft position sensor?

[JosephineLynn]

Crankshaft position sensors mainly come in three types: magnetoelectric induction type, Hall effect type, and photoelectric type. The causes of crankshaft position sensor failure can be divided into three situations: 1. For the magnetoelectric induction type: The fault of the magnetoelectric induction crankshaft position sensor is that the engine cannot start. When checking the engine condition, late ignition is the real reason why the engine cannot start. 2. Hall effect type: The Hall effect crankshaft position sensor is used for sequential fuel injection, ignition timing, and knock control of the engine. When it fails, the transmitted signal is not within the normal range. 3. Photoelectric type: The fault of the photoelectric crankshaft sensor is poor engine acceleration. The engine may automatically stall during startup, and sometimes high-voltage sparks may occur. The reason is poor performance of the ignition system, resulting in weak high-voltage sparks.
