Alright so a few years ago this one dude calibrated my TPS for me. My TB was off the car he calibrated it for .45v closed and 4.5v at WOT. **** runs fine no CEL whatsover. But the way he did it was he had an extra TPS connector with the wires still intact. He connected the signal wire (middle wire) to the wire to the left of it. And left the wire to the right alone (ground wire). So since I've been on Neptune I calibrated my TPS on Neptune so I could determine my Throttle load. but on Neptune my readings are .33v at Closed and 4.33v at WOT. So I decided to recheck it again doing it the same way he did it " which I think is easier since I have no space with the Px manifold. Note that the TB is on the Manifold. Once I tried it out I got 4.48v at closed and .718v at open. Which is obviously backwards. Kinda weird so just wanted to know if how im doing it is wrong or what but i swear thats how the dude did it. He's good with Honda's and kool but after a few deals he became a ********. LOL Here are pictures


WOT


Closed Throttle

and how I wired it


I also tried it with just the middle wire and the ground wire off the TPS connector but same results. The car was on the "ON" Position

Here is an old thread I found also

Ummmmm, You might want to set the meter to dc volts instead of ohm's.

See what you get and get back.

Signal wire = + on the meter. Middle wire on the connector.

Ground = -

You can check it with the - to the battery - also

You should not get any voltage over 5v.

Leave the connector plugged to the TPS when checking.

 

I was a little confused on what to set it onto as well. But this TPS basically replaces the one that is on the harness. My battery is relocated in the trunk so its not possible to ground it to the battery ground. But I will try setting it to Dc volts and see what i get.
