bayside_supra Posted December 30, 2016 Share Posted December 30, 2016 I just refitted mine. You just have to twist the inside parts so that they rest on the correct side of the little spades on the throttle body. Hopefully that makes sense?

Mike2JZ Posted December 30, 2016 Share Posted December 30, 2016 First challenge of swapping the TPS is removing the two screws that hold it in place. If you can do this successfully without rounding them then you are off to a good start. I hate those screws with a passion. On an NA you will need to remove the front top engine cover in order to get to the second screw of the tps. The way you should install the TPS correctly is with feeler gauges and a multimeter in order to tune the location of the TPS to match the throttle plate "perfectly". If you don't have the patience or tools to do this, then install the TPS, aligning the inside grooves with the two metal ends on the throttle body. Once it's on, put the screws in lightly and twist the TPS counter clickwise as far as it will go, then tighten the screws. Your TPS won't be 100% where it needs to be but it will be very close, but without the correct tools it's impossible to dial it in as every TPS and TB is slightly different.

David P Posted December 30, 2016 Share Posted December 30, 2016 (edited) Top Tip for undoing a f tight bottom screw: Remove the throttle body so that you can get at it properly and start the screw moving using a small pair of mole grips. Edit: I had posted a How-To for TPS adjustment, but it appears that the thread I linked the photographs from has been deleted and mucked this resource up. http://www.mkivsupra.net/vbb/group.php?discussionid=190&do=discuss Edited December 30, 2016 by David P (see edit history) Quote Link to comment Share on other sites More sharing options...

Kendo11 Posted December 30, 2016 Share Posted December 30, 2016 For ease of removal next time I'd replace the screws with allen cap ones if you get the time, the screws round off like they're made of chocolate. Quote Link to comment Share on other sites More sharing options...
