The cam sensor rotor, or 'impulse rotor,' works with the camshaft position hall sender to allow the engine control module to know what position the cam is in when rotating with the engine. This allows the control module to calculate fuel, timing, and other various conditions it needs to send output signals to your drivetrain. If bad, the engine control module will send out incorrect signals, making your engine run rough or not at all. Replace yours today and keep your engine running strong.
