Not sure on your year, but the ENG SEN fuse on LS1 cars has the MAF, 02s, skip shift and reverse lockout solenoids on the same circuit. If your is similar check for an open fuse.

the p1657 is the skip shift solenoid. they are all on the same circuit yes but the 20 amp fuse is still good. i even changed it and tested it with a test light and the power is there. i am beginning to think that this is eithier a pcm or a ground issue. are they all grounded in the same place as well?
