hmmm well maybe its the tps
 

ok well my car hits 2k rpm and hits fuel cut, until i shift, and can rev up to 2k again lol so im thinking its the tps..so i got a new one and im ganna reset it tommorow i mean igot a code 41 and the last sensor, no matter hwere i put it, the numbers on the ohm meter just culdnt match up to what they shuld be, i baught a new sensor and am waiting to postition it tommorw, i hope this works

well im pretty sure i set the damn tps right but its stillnot working correctly, now i hit fuel cut, just 200rmps later...its fuckin shitty im ready to sell the supra

dont sell the sup!
if its turbo, check for boost leaks, you could be getting a boost leak and that would cause less air in the engine so it would pretty much bog the motor down with fuel and die.

i dunno, just my 2 cent thoughts

idk anywhere there cul;d possibly be a boost leak tho...when i finished replacing the headgasket it was running liek this, and i was getting a code 41 which is throttle position sensor signal

Id check all the hoses and anything rubber that could be torn or cracked just in case.
but since your gettin a code 41, its gotta be the TPS, but you never know, those pesky hoses.

i dunno man, thats all i got.

good luck with your problem though mate

and its not a bogged down feeling, once my car hits around 2k rpm it just dies, until i shift or until the revs drop. and then gets power right away again, and idk if its a boost leak because the car will start to boost...but then due to the fuel cut i cant rlly see it boost n e more

oh dam well its gotta be something to do with the TPS.
hmmm

idk im ganna try to adjust it again or sumthing, im ready to call it wuits and take it to a shop

idk any more i replaced the tps and thought i had reset it right, but i baught i used one with a new throttle body but its still doing the same thing...im ganna buy a new tps and see if thats it..and if its not..im giving up and either takin it to a shop or selling it

you're hitting fuel cut very early, does it blow alot of black smoke out the exhaust? how does it idle?

When I had to adjust my TPS a short while back I found that using a hacksaw blade was a good thickness to put between the throttle and stopper. Then using the Ohm meter setting the TPS to any reading that wasn't 0 or 1. NOTE: It was hard for me to get it to the specs according to my Toyota OEM repair manual. But the car drives better now. Maybe do that simple test to see if your TPS is causing the fuel cut. I was ready to buy a new TPS too...but I'm sure like mine yours is still okay. I'm running on 250,000+ miles.

it idles fine, at liek a little more than 700rpm..i dont notice any exxesive gasses out of the exhaust..can any1 take a picture of their tps so i can see where theirs is set at? im tryin this whole ohm meter thing tommorow again but i can never get it to spec. and also on one of the fuel lines there seems to be gasoline comming out, but only a microscopic amount, just enought to get the surface of the fuel rail a tinnnnny bit wet, but i dont think thats the cause, its from a bad brass washer on the bottom of it. but idk a pic of sum1 tps wuld help please

ok honstly fuck this car....ive tried to set the tps in every spot, and it just doesnt work...still has the same damn problem with fuel cut around 2k rpm....im readin the tsrm and no matter where i put it the numbers on the ohm meter never change when i move the tps, they always stay at like 6.09k ohm i really feel like blowing this P.O.S. up

VC to E2 should be the same no matter what you do to it.
VTA to E2 is the one that steadily climbs in resistance as you increase the TPS to wide open throttle.
IDL to E2 should read an open circuit as you just open the throttle from closed fully closed.

If you look at the picture in the TSRM you should be using the second one down. The TPS is mounted 180 degrees out between the NA and the Turbo so the terminals will be reversed. If your reading it mounted on the throttle body and reading the terminals like its an NA then your readings will be off.

Also make sure you aren't touching more than one terminal with one lead.
Using alligator clips helps in this case.

For the proper adjustment with a feeler guage use the measurements in the TSRM when its mounted to the throttle body.

Im looking at page FI-100 and FI-101

Thats what mine looks like, its never been removed from my throttle body before. You see that yellow paint mark? That's from the factory.

What terminals are you using when you adjust the sensor?

idk then, im beggining to think its not my tps, bt im gettin the code 41 so idk. im just ganna take it to my auto shop at school and have my auto teacher do it

ok well, i had a brilliant idea, i disconnected the tps, like took the connector off of it...it idles at 2k rpm but it drives perfect...so it has got to be the tps..im just ganna take it to my auto class and have him set it and it shuld be fine
