TPS code

Got the tps code(low circuit) the other day and replaced it.The code was still there.The connector looked bad so I replaced it also.Still got that dang code. I have 5.05 at the reference wire and the black wire is showing ground.,what should the green wire have on it? 12v,etc. Does anyone have the wire colors to make sure the wires are connected correctly?Thanks

Thought they were gray +5V ref from PCM, black ground ref from PCM, and dark blue signal to PCM. In any case the signal wire should be about 0.5V with IGN on TPS closed, and go to about 4.5V or slightly higher with TPS wide open. Is your TB stock, or have you modified it ?
