How Does the Camshaft Position Sensor Work?
The camshaft positioning sensor is usually fitted into the cylinder head of the motor. The reading mechanism is designed to determine how the cylinders are moving, to precisely synchronize how fuel injectors or electronic coils activate. These sensors provide a different array of data to the other important positioning sensor linked to the crankshaft, which is designed to help control the ignition timing and speed of the engine itself.
Each sensor has advanced circuitry that is designed to operate in stressful or hostile environments and to resist powerful spikes or electromagnetic forces. These sensors are designed to provide highly accurate data, especially when an engine is operating at high speed.
The most common type of sensor is magnetic and generates its own alternate current signal that is sent to the electronic control module. However, some later models require their own power source and generate a digital signal to provide the data. If the vehicle has a more complex engine, it may have more than one camshaft position sensor attached.
