cam shaft sensors for 2004 nissan maxima

[muchfome]

I have read some comments on here suggesting a camshaft can cause my nissan maxima to stall out and die. Had the car in the dealership and they said they replaced a camshaft sensor. Car still doing the same thing. What does this sensor do?

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?
