That is about right. You (the original poster) should have invested in a Chiltons instead of a code reader (you can pull codes for free with the use of a paperclip).

Do a forum search for "code 41" with quotes and you will find plenty of information. Basically, the cam sensor circuit has an issue. This means that either the cam sensor itself ($12, fairly easy job), the wires running to the cam sensor to the ECM are pinched, or the cam sensor interruptor magnet located on the camshaft sprocket was thrown ($8 part, but insanely hard to get at...involves removing the front cover of the engine to do it right).

Most likely, the plastic cage around the magnet was brittle anyway and when you gunned the engine the cage finally broke, throwing the magnet into the oil pan.

I have acess to two cars with code 41's...my brothers and my own. My brother got his fixed for (I think) around $300. Mine...um..well, I haven't messed with mine since strangely it hasn't ever effected engine performance
