How many Rev-olutions does a camshaft have?

What happens when the camshaft position sensor does not work?
3. Vehicle will not start The camshaft position sensor gathers information about the vehicle’s camshaft speed and sends it to the vehicle’s engine control module (ECM). The ECM uses this data to determine the timing of the ignition, as well as the timing of the fuel injection that the engine requires.
How much does a bad camshaft sensor cost?
