What are the symptoms of a faulty crankshaft position sensor?
1 Answers
Crankshaft position sensor failure prevents the confirmation of the crankshaft's rotation angle. When the engine control unit (ECU) cannot receive signals from the crankshaft position sensor, the vehicle will exhibit symptoms such as no high-voltage spark, no fuel injection, and failure to start. Below is a partial introduction to the crankshaft position sensor: 1. The magnetoelectric induction type speed sensor and crankshaft position sensor are installed in upper and lower layers within 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 type speed sensor and crankshaft position sensor operate as signal generators utilizing the Hall effect. The photoelectric type crankshaft position sensor is typically installed inside the distributor and comprises a signal generator and a signal disc with light holes.
