crankshaft sensor
The crankshaft position sensor is one of the most important sensors in the engine electronic control system. It provides the ignition timing (ignition advance angle) and the signal to confirm the crankshaft position, and is used to detect the top dead center of the piston, the crankshaft rotation angle and the engine speed. The structure used by the crankshaft position sensor varies with different models, and can be divided into three categories: magnetic pulse type, photoelectric type and Hall type. It is usually installed on the front end of the crankshaft, the front end of the camshaft, on the flywheel or in the distributor.
