has anyone ever had a tps sensor read backwards?
 

i did just install new plugs but the wiring was color coded so i dont see how i could have screwed that up. I'm thinking that its the stinking skunk wiring harness, but I'm open to ideas.

I'm getting like 4.5v at close throttle and 0.5v WOT.

yellow is +5v and green is ground.. im looking for a good pin out right now to see whats up

Since I replaced the map and tps clip at the same time i could have used the maps green wire for the tps since they are both the same color.

yup...ive sseen it plenty of times on swap wiring screw-ups.

there are 3 wires on the tps..switch the outside 2 around..and you'll be set.
