Camshaft Position Sensor

The crankshaft position sensor is also called crankshaft angle sensor. There are three common crankshaft position sensors: electromagnetic, Hall, and photoelectric.

The crankshaft position sensor is generally installed in the distributor of the vehicle, or the side of the crankshaft pulley and the front of the camshaft.

The crankshaft position sensor is a very important sensor in the vehicle-controlled ignition system. Its function is to detect the top dead center signal, crankshaft rotation signal and engine speed signal, and feed it back to the computer, so that the computer can control the fuel injection amount and fuel injection. Timing and best ignition timing.

The crankshaft position sensor needs to cooperate with the camshaft position sensor to determine the ignition timing, and start ignition at the end of the compression stroke. Through the crankshaft position sensor, you can know which cylinder is in the compression stroke, so the driving computer will give instructions to which cylinder to ignite.

Therefore, if the crankshaft position sensor fails, the driving computer cannot receive the signal from the crankshaft position sensor. In order to protect the engine, it will not ignite or spray fuel. The phenomenon of the car is that there is no high voltage, no fuel injection, and no fire.
