Looking for a bit of help please.
I had no TPS signal when testing using the correct 1.7 adjustment sequence with an ohm meter. Sucessfully installed a new board . Still no signal when testing & doing set up adjustment. even when working through simulated accel and decel when internal contacts change. The meter works . (tested other known components) Tested the connection from "pick up" to board and all work so I know I am making board to contact on all fixed and movable connections is good. I am thinking that the other part of my TPS is bad ...Cleaned contacts. I posted a photo (photo not mine but arrows to area of concern. Any help or is it time for a "new" TPS.

Plug spade to finger and plug spade to trace is good ...
With the cover off and the unit mounted back on the TB, If I move the throttle the center spring connector (not changed) does not make contact with the post. (if I push that with a small screwdriver it does make contact, as I believe it should.) I can see what it should be doing as the throttle is opened ... one circuit is active when in accel mode and it then is open when in decel ... that's not happening always "open" Please excuse me if I am using incorrect component names or not speaking "letric" correctly ... but I do understand the principals. |
