I have just done all the cam seals and timing belt with everything around there (tensioner, idler, waterpump etc.) and after putting everything back together I have a very low idle and the car dies as soon as I get off the gas. I got codes 0340 and 0341. I am now wondering if I installed the cam position sensor housing the wrong way when putting everything back together. Can someone please show me a pic of the cam pos sensor housing on their 2000 S40 so I can see which way the cable connector is going? is it going to the back (as I have it installed right now) or to the front. I'm not even sure if it can be installed the wrong way but its night and I can't go check now.
Thanks a bunch!

 

Here is mine. Sorry this is a few days late as I just got the car back together after a broken timing belt/bent valves.

 

Thank you. Looks like I had it on there right. I took the car to the dealer and had them diagnose it for me. It seems like the timing was slightly off. The DIY camlock tool described in the Haynes manual sucks because it bends when loosening the torx bolt on the vvt sprocket. That must have messed up my timing. I had the dealer fix it and $400 later the car runs stronger than ever.
