meekrog Posted September 26, 2013 Share Posted September 26, 2013 I replaced my TPS and now it starts right up but promptly dies. I reattached all the vacuum hoses, harnesses etc correctly... switched back to old sensor and same issue. Do I just need to adjust it? or should it at least run even without? I checked through previous posts on the subject but none quite matched up so i was hoping someone has had this happen and could shoot me some advice.

Alkorahil Posted September 26, 2013 Share Posted September 26, 2013 Yes, there is a potentially time consuming process to set the correct position on it. The TPS is not 'plug and play' You need to download and consult the FSM for the correct proceedure.....and have a good supply of patience on hand when doing it.

meekrog Posted September 27, 2013 Author Share Posted September 27, 2013 Okay, found a couple places with how to do it, any line on a full downloadable factory service manual? Will be attempting to get it figured out tonight, I fiddled will it a little yesterday before I got ahold of a multimeter and got it to run nasty but run, so hopefully a good calibration will work. Wish me luck... Haha Link to comment Share on other sites More sharing options...
Precise1 Posted September 27, 2013 Share Posted September 27, 2013 As far as I know, the earliest downloadable FSM is 1994 and that won't help you a bit as that year is MPFI and you have TBI. You may have to buy something off of Ebay or something... B Link to comment Share on other sites More sharing options...
meekrog Posted September 27, 2013 Author Share Posted September 27, 2013 Yeah, I have been checking periodically for years for a freebie... Chilton and haynes just don't cut it for some things. Link to comment Share on other sites More sharing options...
Precise1 Posted September 28, 2013 Share Posted September 28, 2013 Agreed! (I have all 3) I'll keep you in mind if I run across anything, and good luck. B Link to comment Share on other sites More sharing options...
Kingman Posted September 28, 2013 Share Posted September 28, 2013 (edited) Wonder what it does unplugged? I run mine without a TPS/and misadjusted for a few days and there was barely any difference. Edited September 28, 2013 by Kingman Link to comment Share on other sites More sharing options...

Haha I have a FSM for the 89 d21/wd21 which covers the tbi unit and how to adjust the tps, it's about 155mb and I can't remember where I got it from but if you want I can upload the two pages which show how to adjust the tps.

ahardb0dy Posted September 30, 2013 Share Posted September 30, 2013 In the FSM section if you follow the link from NICO in the parent directory under hardbody there is a manual for the 1989 Hardbody which has the TBI info in it, here is the link: http://www.nicoclub.com/FSM/Hardbody/ Link to comment Share on other sites More sharing options...
meekrog Posted October 2, 2013 Author Share Posted October 2, 2013 Thanks a ton, got that TPS all worked out. Went to smog it and ran high HC at idle... Vaccum leak probably, as before I replaced the TPS it passed HC's and only failed CO. Link to comment Share on other sites More sharing options...
