Sorry to hear you’re experiencing car trouble! A cam sensor—or camshaft position sensor, as it’s rightly called—is an electronic sensor that monitors your camshaft’s speed and position. All of the data gathered by the cam sensor is then fed into your vehicle’s engine control module (ECM) and used to determine how much fuel is needed and when to ignite it.
Your vehicle’s camshaft is a rotating device that converts rotational motion into reciprocal motion in order to open your engine’s valves in time with your vehicle’s crankshaft. The cam sensor monitors the camshaft’s movements, gathering data to be fed into the ECM, so as to ensure the engine’s internal combustion process operates as smoothly as possible.
