Thanks Arthur,

I'll check the AC volts for sensor function.

Any help on checking wiring? I'd like to verify continuity. Where do they lead, what pins on computer??

ALso, clearing the code using a OBDII meter rest the CEL but left the code in the computer. The CEL returned, and I'm not sure if this means there is a problem with the camshaft position sensor or circuit, or if I need to clear the computer entirely. This time I'm going to use the battery method, to verify I can get the code to disappear. Then if it comes back I will know it isn't a one-time fluke!

thoughts?

Paul
