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.

Fixed it ! Good to go ...
I tested and re-tested and figured as I actually thought that the 2 "posts" and the contact they make with the "sprung contact' ... just wasn't good. I cleaned and actually had to use some very fine wet / dry paper on the post and the contact. OK ... every thing works and I have good readings. the board did need to be changed as its trace contacts were very worn , If you do the board, pay some attention to the pin contacts as well ... Thanks for your help "cabinetmaker" |
