The crankshaft sensor is usually installed inside the distributor and is one of the most important sensors in the control system. The crankshaft sensor primarily serves the following functions: 1. Determine the position of the crankshaft, i.e., the angle of the crankshaft. It typically works in conjunction with the camshaft position sensor to determine the basic ignition timing. 2. Detect the engine speed, hence it is also known as the speed sensor. 3. Detect the top dead center position of the piston, thus it is also referred to as the top dead center sensor, including detecting the top dead center signals of each cylinder for ignition control and the top dead center signal of the first cylinder for sequential fuel injection control.
