Ok, after more testing and alot of run time, the correct Throttle Position Sensor voltage (closed TB) is .30V . Anything higher, like .44 or .50V will give you a high idle.

If your TPS goes out, buy the OmniPower sensor for $75 instead of shelling out $476+ for a whole throttle body.

case closed

For some freaky reason my TPS died today... anyone have a spare or should I just use the omni sensor?

where do i get it ?

Hello S2kart - any new wisdom on the TPS failures ?

So far I've run the TPS at .50, .45, and .40. They all work after doing the ECM Idle Learn, although the idle speed will be higher with increased V. I'm now going to set it back to .30V (how the car originally was)

By the way, do not use the Idle Learn procedure as defined in Helms (running the engine at 3Krpm while parked, until its warmed up), it can give you an EPS fail. Instead, warm up the engine, then reset the ECM, then do the idle learn.

Also, to get the Omni Port sensor down to .30V you have to elongate the adjustment slots, but hey, its Omni Port sensor =$75 + 10 minutes with a Dremel VS. $476 for the whole TB from hondaautomotiveparts.com .

any new wisdom on the TPS for the S2K ? My check engine light came on on my 2002 model (103k Miles). Engine runs rough at idle with about 450 rpm. Honda quoted $1,113 to replace entire body. Looking for options to safe some dough.
