Default Multiple Engine Codes- Check Engine (posted in Sept 2010)

I have a Volvo 2000 V70 with the Check Engine light on. If i reset the codes, i get 4 different codes back within an hour of operation. A faullty knock sensor is one of the codes. I had it replaced at a dealer after their diagnosis with no change in operation. This seems to say to me that the fault is not any of the indicated. Does anyone have any idea what the problem is ?

thanks

I would say possible wiring or ECU issue.
