What are the symptoms of a faulty crankshaft position sensor?
1 Answers
Symptoms of a faulty crankshaft position sensor include: First, the malfunction indicator light will illuminate, and the engine may exhibit shaking or emit white smoke. The engine starting time may become prolonged, or it may fail to start altogether, and cruise control may not function properly. If the crankshaft position sensor is damaged, the engine control unit cannot receive the reference signal during startup, preventing the ignition coil from generating high-voltage electricity. If the engine is not started within 2 seconds of turning on the ignition switch, the engine control unit cuts off the control voltage to the fuel pump relay, stopping power supply to the fuel pump and ignition coil, resulting in the vehicle's inability to start.
