The cam shaft sensor senses the position of the piston and send the signal to the Engine Control Module (ECM). The ECM uses the cam shaft signal and other inputs to send fuel and spark to the cylinder.

There are many thing that can cuase the engine to stall, do you know why the dealer replaced the sensors? are there any other symptoms? is the engine light ON?
