alzmoore Posted September 15, 2018 Report Share Posted September 15, 2018 Hello, I've finally managed to get back to my 1989 SE project.. I can't get the tps to align properly with the screw holes on the end of the throttle bodies and get the right voltage and my mate is convinced that there is an adaptor missing from the end of the throttle spindle. The shaft end is basically a small flat spade on the end of the shaft which fits into the tps. It does operate the switch...... but should the be an adaptor on the end of the shaft that fully fills the 'hole' in the tps... And if so where could it get one...? Many thanks Quote Link to comment Share on other sites More sharing options...
Gold FFM Barrykearley Posted September 15, 2018 Gold FFM Report Share Posted September 15, 2018 No - that sounds correct. post up a picture. Are you sure the TPS you have is correct ? And are the butterflies closed? What voltage are you getting? Quote Only here once Link to comment Share on other sites More sharing options...
alzmoore Posted September 15, 2018 Author Report Share Posted September 15, 2018 Barry, Thanks for the reply. I can only get a voltage if I rotate the tps clockwise about 30 degrees, to give the required 0.5-0.7 volts. I have to clamp in this position as the holes are way out of line. The throttles are closed and it will start and run (unevenly) in this position. I think the previous owner had dismantled the bodies for powder coating, but i can't see how you could reassemble the butterflies the wrong way round anyway....very puzzling. I got a new tps from SJ and it's just the same as the one the car came with. i will get some photos tomorrow Alan Quote Link to comment Share on other sites More sharing options...
Gold FFM Barrykearley Posted September 15, 2018 Gold FFM Report Share Posted September 15, 2018 The TPS fits on the end of the rod which the butterflies are attached to. it should be as simple as locate the TPS onto this and bolt on. Then fine adjust for 0.51v or thereabouts. The slot in the TPS is like a bow tie shape so there’s a whole lot of movement in that. pics might help - it’s sounding to me like the TPS might be wrong Quote Only here once Link to comment Share on other sites More sharing options...

Many thanks Just seen this thread , sorry for slow reply... The answer to your question is. YES see pic ... The little Item just left of the std TPS at the top of pic is what you need... It slots over the Throttle spindle bayonet end and adapts to the TPS insert...... hope that helps answer your question and solves your problem 1 Quote Link to comment Share on other sites More sharing options...
Gold FFM Barrykearley Posted September 16, 2018 Gold FFM Report Share Posted September 16, 2018 I don’t recall ever seeing that on any of mine and it’s not on the parts book piccys either @CHANGES - I’m puzzled a bit. id go and take one off - but the laptops knackered and I won’t be able to set the voltage - so I probably just never looked properly Quote Only here once Link to comment Share on other sites More sharing options...
alzmoore Posted September 16, 2018 Author Report Share Posted September 16, 2018 Brilliant many thanks. Just need to find one now... Will try SJ tomorrow. Quote Link to comment Share on other sites More sharing options...
sailorbob Posted September 16, 2018 Report Share Posted September 16, 2018 I believe the TPS shaft adapter is part of the throttle body assembly and, AFAIK, it isn't sold separately. Quote Link to comment Share on other sites More sharing options...

alzmoore Posted September 17, 2018 Author Report Share Posted September 17, 2018 Bob, It looks like you are right. Sj can't source it... So scratching my head now for a solution... I'll try the other spares outfits and scrappers, but if anyone has any ideas please let me know. Thanks Quote Link to comment Share on other sites More sharing options...
sailorbob Posted September 17, 2018 Report Share Posted September 17, 2018 Maybe cars that use the same TPS may have a similar shaft adapter on their throttle bodies? Quote Link to comment Share on other sites More sharing options...
