the year matters most in this case, but it helps if you list in your post what vehicle you are dealing with. each years have there own settings and parts.

On my 86' I believe TPS voltage at idle is 0.54 . I would think the 85' would be the same as the engine is the same, but I cannot confirm that.

I think the range is like .47 to .63 I would have to check my FSM but .54 is what every one uses.
