I just took another look at the workshop disk - seems Joe is right and there is something fishy about both sensors being fubar - I'm taking a closer look when I get home this evening. Either the dealer is lying and I only need one (and they were too lazy to isolate which one is bad), or there's something going on with the harness that feeds the two. If the TOD ECU was bad it would show a different trouble code - but who knows what the dealer did to determine what was wrong. I took a hit from a piece of tire on the interstate last week - struck the passenger side front of the VX - no damage but I did notice the cladding was pushed in a bit - it could be pinching part of the harness that loops around the front of the VX - I'll loosen things up a bit when I get home this evening and see if it makes a diff (was going to do that anyway).
