zane9000 Posted June 7, 2006 Share Posted June 7, 2006 Anyone know what resistance range the TPS is supposed to provide? EDIT: OK, a while back I was trying to fix another problem with my MegaSquirt. During this time my TPS was working like a champ. I was getting frusturated with the problem at hand so I took a minute for the simple pleasure of playing with the gas pedal and watching the MegaTune gauge move up and down (I know, Im an idot). Well, after about a minutes of playing with it the meter just got stuck at about 50%. At first I thought maybe somehow a wire came loose, so I pulled all the old (shody) wiring out and ran some brand new wire with good connections. Nogo. I thought maybe the TPS went bad, which lead me to my original post in this thread. But I figured out what resistance range my TPS is supposed to be putting out, and it tested good. I am 100% sure that it is wired correctly, I have 5v comming out of the MegaSquirt all the way to the TPS and I know the ground has a good connection. It seems that the MS isnt accepting a signal input for some reason. I checked continuity all the way from the TPS to the MS board and there is a solid connection all the way. I tried taking the +5v and running it directly into the signal line and there was no effect at all on the Mega Tune screen. Im really stumped on this one...

veritech-z Posted June 7, 2006 Share Posted June 7, 2006 Have you got a particular TPS in mind, or just TPS's in general? Quote Link to comment Share on other sites More sharing options...

zane9000 Posted June 8, 2006 Author Share Posted June 8, 2006 OK, I think I traced the problem to one section of the board. Attempting to rewire now.... Quote Link to comment Share on other sites More sharing options...
