david_steverson Posted August 25, 2006 Share Posted August 25, 2006 On a previous post I received some helpful advice on poor acceleration. I replaced my oxygen sensor. Other comments mentioned the throttle position sensor. I have been scouting around for one and found they are very expensive. Can anyone suggest a source for this item? I have tried my local Subaru dealer, parts stores and even found one on Amazon (strange, that). My car is '94 Loyale with single throttle body injection.

patkennedy78 Posted August 25, 2006 Share Posted August 25, 2006 Your local junkyard or Pull n Save should have plenty. I've grabbed two or three last time I was there just to mess with / look at. If you really want one I'll send one to you, but they could be bad or worn out. Quote Link to comment Share on other sites More sharing options...

The TPS from any EA82 model with SPFI should work. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 25, 2006 Share Posted August 25, 2006 They RARELY fail. Test it first - it's easy to test with a multi-meter. GD Quote Link to comment Share on other sites More sharing options...
patkennedy78 Posted August 25, 2006 Share Posted August 25, 2006 Maybe not fail completely, but I've read alot here about them wearing out in spots, or getting 'flat spots" so you have to feather the gas pedal a bit when trying to accelerate. The end of this post talks about it: http://www.ultimatesubaru.org/forum/showthread.php?t=41569 #22 is the test procedure. Quote Link to comment Share on other sites More sharing options...
david_steverson Posted August 25, 2006 Author Share Posted August 25, 2006 Yes, it's the flat spot issue I'm working with and there aren't many Subie's around here. I read in my manual about testing, which I hope to try this weekend, I just thought I'd try to line up a-not-quite-so-expensive source for the part.

GeneralDisorder Posted August 25, 2006 Share Posted August 25, 2006 I have several extras, and I can test them before I send you one. $10 plus shipping and I'll send you two of them.... GD Quote Link to comment Share on other sites More sharing options...
Silent Bob Posted August 25, 2006 Share Posted August 25, 2006 I've been having the same sort of off idle bogging/hesitation/flaky TPS problem. Anyone ever tried adapting a TPS off of some other vehicle to a Sub? It would be nice to be able to use a $35 GM/Ford/whatever sensor vs. the $350 Subaru version of the same thing. Assuming you could find one with the same sort of output range... Quote Link to comment Share on other sites More sharing options...
daeron Posted August 26, 2006 Share Posted August 26, 2006 Ive watched every thread about this like a hwak because mine has been failing, and i have yet to read about any replacement... but im no soobie scientist, and if there is an idea for an upgrade i would be interested as well... :- ) Quote Link to comment Share on other sites More sharing options...
