The role of the camshaft position sensor

The main function of the sensor on the camshaft position is to collect the action angle signal of the camshaft, and then input it to the electronic control unit in the form of voltage.Yuan, which is what we often call ECU. This is mainly to be able to determine the timing of the ignition and the timing of the fuel injection, so whether it is at the intake or exhaust, there will be a sensor of the camshaft position.

Therefore, once the camshaft sensor transmits the signal to the control unit, it will control the fuel injection ignition timing and deflagration control in a corresponding order, and the camshaft sensor will also be used to identify the first ignition time when the engine is started. So that is to say, if the sensor of the multi-axle position is damaged, it will easily cause difficulty in starting the engine and invalid ignition.

So when the car owner encountered difficulties in starting the engine and ineffective ignition as mentioned in the appeal. Then the owner needs to consider whether the sensor of the camshaft position is damaged. If the sensor is damaged, it must be replaced in time, otherwise it will easily cause the owner to be unable to use the vehicle normally.
