If you can source one, try swapping the map sensor with a known working one, reset the ecu and see if it works. http://www.supraforums.com/forum/sho...o-swap-problem

 

Ok got a new one, will try it out when it comes in

 

update, swapped with another ecu, and another MAP sensor, still same problem wont rev up past 2000-2500 rpm and idle is bad like tis gonna stall out like at 200-350 rpm

 

Man this is turning into a tragedy. Do you have a wideband on it by chance?

 

yes i do, i have the aem one

 

how do you properly install the TPS onto the throttle body? do you turn and guide it down until the screw line up?

 

not sure if this matters but i dont have a connector for the sub throttle actuator "the motor thing to the left of the TPS. i think Dr tweak removed it.

 

Code 31 is Volume air flow meter circuit so it sound like you are using a USDM mk4 ECU not an Aristo

 

Code 31 is universally used for MAF or MAP depending on which ECU you use. It does not matter that the sub TPS is gone. Should not effect engine operation. I cant help you with installing the TPS, I have never had mine off. What are the AFRs doing at idle and when you rev it?

 

Have you removed the patch harness totally and plugged everything directly into the ecu?

 

yes patch harness is removed, a/f ratio at initial cold idle is around 10-11 once warmed up 13-14, if i give it any gas it drops down to like 9. now i think i may be onto something here, i took off the main TPS which i bought brand new from Curk on SF. the part number on it reads 89452-22090. now looking at the sub TPS on the other side of the TB visually they look identical. i found my broken TPS that i replaced and the pn reads 89452-22080. could you guys verify what your main TPS part number is for me. i think i may have gotten the sub tps and put it on the main one. which would kind of explain the problem im having. since the pins for signal and battery power are totally opposite on them.

 

My search indicates that the 090 is for a GE and GTE trac blade, and the 080 is the main TPS for a GTE. I think you may be onto something as well IIRC, the sub TPS works backwards or is wired backwards compared to the main. That would explain quite a bit LOL. I'm surprised you were able to go through the adjustment and testing procedure on it without issues.

 

Yes, I verified that 080 is the PN on my main TPS. I have no sub TPS since I deleted TRAC.

 

ill update soon when i get the correct TPS sensor lol. im surprised also that i was able to do the adjustment

 

Yes, but it is adjustable so you will need to dial it in.
