Taggy Posted August 13, 2012 Share Posted August 13, 2012 Can someone tell me what this black square unit does on the left hand side in the picture, mine has taken a wallop while fitting and everything inside is bent to hell, what does it do? Quote Link to post Share on other sites
Whitegv Posted August 13, 2012 Share Posted August 13, 2012 The tps? Mounted on the side of the throttle body?If so its called the throttle position sensor. on starlets i was told that it only really tells the ecu when you've let off the accelerator. this tells it to stop adding feul special you aren't popping and banging as you engine brake i spose is the best term. it will run without it however obviously Toyota didn't put it on for fun so best get one sorted asap Quote Link to post Share on other sites
Taggy Posted August 13, 2012 Author Share Posted August 13, 2012 (edited) yeah thats it, well the contacts inside are all bent touching each other, when i start my car (which is ok) when i touch the acellerator at idle, it nearly cuts out then starts to rev up then cuts out then starts to rev again and keeps doing this yo yo thing with the thottle turning on and off all the time, do you think thats causing it?

LukeSR Posted August 13, 2012 Share Posted August 13, 2012 Yep most probably dude Quote Link to post Share on other sites
Glanza AuA Posted August 13, 2012 Share Posted August 13, 2012 my rev was going on and off on the counter, i did the TPS procedure from http://www.toyotagtturbo.com/forums/showwiki.php?title=TPS+throttle+position+sensor+set+up+procedureand now it sits perfectly still Quote Link to post Share on other sites
Whitegv Posted August 13, 2012 Share Posted August 13, 2012 Un plug it first and see if it makes a difference. Mine ran almost perfect without one whilst i sorted another out Quote Link to post Share on other sites
Taggy Posted August 13, 2012 Author Share Posted August 13, 2012 yeah i just unplugged it and its made no diference, so i dont think thats causing the problem.It wasnt doing this yesterday though so somthing i have touched has caused it! Quote Link to post Share on other sites
Whitegv Posted August 13, 2012 Share Posted August 13, 2012 Is there no engine warning light on? if its hunting up and down the revs try cleaning the idle control valve. (unit on right hand side on the end of inlet mani if looking at pic) there's a guide on tgtt Quote Link to post Share on other sites
turbo Grant Posted August 13, 2012 Share Posted August 13, 2012 need a new one dude. the engine wont run right without it. you could probably run with out it by a slit pin in the plug. not sure whitch wires with out loooking at a tps sensor Quote Link to post Share on other sites
mattyD Posted August 13, 2012 Share Posted August 13, 2012 if you need a new one, try an and get an auto tps if your getting your car mapped up these are better to use as with a manual tps its either say 1 or 100 (on/off) and nothing in between where as an auto you can control it right through so will be more accurate, does that make sense? lol Quote Link to post Share on other sites
