What happens if the crankshaft position sensor fails?

[OChloe]

The failure of the crankshaft position sensor will result in the inability to determine the rotation angle of the crankshaft. The engine control unit (ECU) cannot receive the signal from the crankshaft position sensor, leading to symptoms such as no high-voltage electricity and the car failing to start. Below is a partial introduction to the crankshaft position sensor: 1. The magnetoelectric induction speed sensor and crankshaft position sensor are installed in two layers inside the distributor. The sensor consists of a permanent magnet induction detection coil and a rotor (timing rotor and speed rotor), with the rotor rotating along with the distributor shaft. 2. The Hall effect speed sensor and crankshaft position sensor are signal generators that utilize the Hall effect. The photoelectric crankshaft position sensor is generally installed inside the distributor and consists of a signal generator and a signal disc with light holes.
