Where is the crankshaft position sensor installed?

[MacKimberly]

The crankshaft position sensor is installed either inside the vehicle's distributor or near the crankshaft pulley. The working principle of the crankshaft position sensor is as follows: 1. The crankshaft position sensor is mounted on the flywheel and uses pulse signals to detect the crankshaft position, determining the engine speed and the relative position of the pistons during crankshaft rotation; 2. The engine control unit utilizes the information provided by the crankshaft position sensor to generate ignition signals and injection pulses, which are then sent to the ignition coil and fuel injector respectively. Types of crankshaft position sensors include: magnetic induction, Hall effect, and optical. The functions of the crankshaft position sensor are: 1. To determine the crankshaft's rotation angle and the engine's speed; 2. The crankshaft position sensor works in conjunction with the camshaft position sensor to determine the engine's ignition timing.
