cam position sensor?

What does the cam position sensor do?
Would an oil film on it affect its operation?
Anyone help please
Thanks,
Keith

the cam sensor lets the ecu know when to fire the plugs, as for oil on the sensor im not sure if it would effect it as uses magnetic waves to read, now i cant confirm all of this as im still learning this stuff, just trying to help keith

I would think it would show a code. I just replaced mine in my Outback. The car had no power and would hardly run. It was like it had a clogged fuel filter, but worse. It turned out to be the cam sensor.

I just replaced mine in the SVX. All hell was breaking loose, melting cats, killing O2 sensors, you know...fun stuff. Turned out it was a bad cam sensor.

The cam sensor works together with crank sensor #2. By counting the number of pulses from each sensor, the ECU can determine the current position in the firing order, in other words, it can figure out which cylinder is supposed to fire next.
