What are the symptoms of a faulty crankshaft sensor in a car?

[MargaretAnn]

Crankshaft sensor failure exhibits the following symptoms: 1. The malfunction indicator light illuminates. 2. The engine can continue operating using the camshaft position sensor, but the starting time may be prolonged. Additionally, the cruise control and exhaust brake systems may malfunction, accompanied by engine shaking and white smoke emission. However, there is no significant change in power performance, and throttle response remains normal. 3. Diagnostic trouble codes may be generated. 4. Abnormal signal disc readings. Introduction to crankshaft sensors: 1. The crankshaft sensor plays a crucial role in the sensor system. It determines the crankshaft position, monitors engine speed, and detects signals including the top dead center signals for each cylinder (used for ignition control) and the first cylinder's top dead center signal (used for sequential fuel injection control). 2. The crankshaft sensor typically works in conjunction with the camshaft position sensor to determine the basic ignition timing.
