Hey, what's up? I attempted to check & adjust the TPS on my Trooper today following instructions from the "Archives". When I unplugged the TPS, I noticed on the plug side that there is no black wire. The center wire is blue with a red stripe down it's length. On one end of the plug the wire is blue with a yellow stripe & the other side is blue with a white stripe down it's length & one red band that goes around...like a ring. Following the instructions using my digital ohm meter, I checked every possible combo with the red & black leads & never came up with a reading of 5 volts. No matter which wires I put the meter leads on, the only readings I got were 0 or 11.4. Anyone know which of the colored wires is the ground? Also, for those of you who remember the demon that's haunting my truck.....would disconnecting the TPS cause diagnostic codes to come up on the dash? Even after I plugged the TPS back together, codes 25 (air vacuum switching valve) & 33 (fuel injector circuit). I'll be as clear as possible. Both the rubber boot on the TPS plug & the rubber boot on the fuel inj. wiring (closest to the TPS) both seemed a tad melted. Any thoughts...........TY
