TPS Backprobe Question
99 F250 LD Fwd w/ 5.4
I'm trying to diagnose my TPS . I have a Chilton repair manual that
say's the closed throttle # should be .5 to 1.0 volts and the open
should be 4.5 to 5.0 volts. Mine is 3.5 closed and goes to .1 open.
Just the opposite. What's up with that? Is the book wrong or is the TPS bad?
