well i finished my h2b swap yesterday and took it out for a ride and there's litterally no difference from the single cam...theres absolutely no power/torque curve... it is throwing a tps code. could a bad tps sensor cause a huge power loss?

bump for a fat kid that needs a ride!!!

 

fix your tps and you should see an improvement

 

so i replaced it with a used one and reset the ecu and the code was still there. i sure hope they were both bad

 

did you set it so that its close to .5v closed throttle and 4.5v wide open, also souble check your wiring to make sure everything is secure

gl

 

i'll check that. thnx. im running open header too would that cause my compression to decrease in any noticable way?

yeah, check the wiring and make sure that it's set to spec.

the open header will hurt your low rpm performance a bit, but as it opens up it should perform well.

i believe the TPS issue has put you in limp mode. the engine has pulled timing, dumped fuel and just overall protecting itself from getting hurt.

 

okay i checked the voltage. its reading 0 at closed throttle and 1.56 at wot. so what could cause this? ive got 5 volts coming into the plug through the yellow wire. could it be the plug itself?

 

up to the top. need this problem taken care of quick guys!!!

 

loosen the screws on the tps an turn to see if you can chiange the readings

 

i tried that and the most i could get out of was 1.5 at WOT

 

that tps is beat then...that's insane to not be able to get more...

 

agreed...i'll try another tps i guess. this bamboozles me...

 

bump. has anyone had this problem???

 

AFTERNOON BUMP. waffles are cool

 

no need to bump this thats your problem your tps i done. .45 volts at closed and 4.5 at wot

exactly what i was thinking. nothing we can say will make that TPS replace itself haha

 

yeah but ive tried three different ones and it is doing the same exact thing. ive gotta new dh racing TB and tps on the way so its cool

 

I would check your wires(nobody seems to do that at all on these threads, they just keep swapping parts). If three different TPS's all failed, sounds like a wiring issue, not a component issue.

 

i tested the yellow power wire and its good. anyone know which pinout the tps is?

 

d11 is TPS
