A camshaft position sensor helps the engine control unit ecu determine the precise amount of fuel the engine needs at any given moment. When the camshaft timing pin comes close to the sensor head the voltage at the signal wire drops to zero. It is mounted at the end of the intake camshaft see fig. The cmp sensor provides the camshaft position information called the cmp signal which is used by the powertrain control module pcm for fuel synchronization.

The crank and cam sensor operate in sync with each other. Without the cam sensor the vehicle may not. A camshaft position sensor is often situated near or around the crankshaft. This small component is an important part in the engine largely because it sends information to the on board computer that is used to determine the speed and position of the camshaft.
