Are you saying one cam is ten degrees off, and the other is zero degrees? Or both cams are ten degrees off?
In the data field setup options, select cam position for b1 and b2, and both b1's for solenoids (it's a label bug, they'll fix it).
At idle in park, at temp, you should see zero solenoid voltage applied and both cams sitting around zero, plus or minus 2.5 degrees or so...but mostly zero. Any amount of throttle the cams should advance, and be somewhere between zero and thirty at 2,000 RPM (still in park).
If at idle one cam is ten degrees ahead or behind with no voltage applied to the solenoid, it's possible a mechanical timing issue (chain off by a tooth). Would not be any visible evidence that your truck had the timing chain repair, but it's very possible as 07's were affected. I stumbled across NDS in the first place trying to figure out if this was my issue, and a Maxima owner had used it and saw one of his cams was one tooth and ten degrees or so off at idle.
FWIW, I did not notice that only one of my cams was advancing (oil seal improperly repaired). Only chased it down when I got a couple P0011 codes. Engine will appear to drive fine as, well...it's kind of designed to run with the cams +/- 40 degrees out of phase with VVT.
It does drive better with everything working of course.
