Hmmm - interesting. My 1996 Ram FSM don't go into that kinda detail on
troubleshooting sensors. Then again - maybe I haven't found it yet - that thing is
so big 8-). Sorry - I don't know why its not getting higher voltage at WOT. I
don't think it has any perf. implications as long as you are reaching what the
computer thinks is WOT. I would bet that the TPS as mounted in the TB has a limited
travel distance thus keeping it from reaching any more than it is currently. You
could test this theory by playing with it while not mounted on the TB (removed but
still plugged into the harness). Again - I don't think it would benefit anything.
I'll try to verify the exact voltage that engages WOT.
