Darryl, try the search feature for "cam sensor" or "code 41" You will find lots of links.
The sensor (pickup) is easy to change out. You will need a mechanic'* mirror, a flashlight and a 10mm socket. But often the problem is that the interrupter magnet has been thrown from its little hole in the camshaft sprocket inside the timing (front) cover. There is a procedure described by Padgett where you replace the magnet through the hole with epoxy. I have the tools, so I prefer to remove the cover to change them. That gives me the opportunity to find and remove the little bits of magnet so they don't get in harm'* way.
Here is a link with photos showing where the sensor is located on an L36. Even though you don't have the L36, your cam sensor is set up the same way. http://www.bonnevilleclub.com/forum/...ic.php?t=67136
