The gray wire is ref voltage, it should read close to 5 volts, key on. With everything hooked-up, take a reading from the signal wire, dark blue, key on engine off, while you watch the voltage reading, have helper work the throttle, see if voltage reading moves up and down smoothly. If it does, I don't see a problem with the tps?
