Chaps, an update - this is turning a bit strange - any advice please. OK all oygen sensors are disconnected and the fuse is still blowing. BUT when all this happened I was also getting P0010 and P0020 which are Camshaft position Actuator circuit bank 1 & 2. Now the thing is , I can't see from a wiring diagram how these are connected to the same fuse . However, that's not to say the wiring diagram isn't complete. So my question is does anyone have actuator / camshaft sensor wiring diagrams or looking at Richard's diagram further up , I'm think that PIN41 might have something to do with it as , even with all the sensors disconnected there is still a link from the fuse box to pin 41. I think this is now not straightforward!! I haven't disconnected the camshaft sensors yet as I really need to understand the wiring first. Thanks , Worried from London!
