Approx. Two weeks ago, I noticed my engine light stayed on. I took my vehicle to a reputable auto shop in which they told me that once they put the vehicle on the diagnostic machine, it problem was the CAM shaft sensor.

First question, what is the CAM shaft sensor and the purpose?
Second question, will my vehicle eventually shut down?

For a couple weeks after I had the cam shaft senor replaced, the engine light turned off. Now its on again. Please advise. Thank you.

The camshaft sensor tells the computer the position of the can so it can delivery the fuel etc.I need from you the exact code numbers you have right now not code descriptions? If you don't live in California you can go to a auto parts store like auto zone and have your codes scanned for free.
