S2 RB25DET TPS

[mikalkouki]

So the tps on my s2 rb25 fried on me aparently. It now reads 5v at closed throttle and .0-.4v at WOT ????

Is there a x-ref of any kind for the s2 tps or does anyone know where I could find one?

[eh?]

It's wired backwards.

it read properly 2 weeks ago... how could it change all of a sudden? I'm pretty sure something is wrong internally as I havn't changed any of the tps wiring. Also, what I meant by .0-.4v is sometimes it reads .4v and sometimes it reads .0v at WOT.

just to solidify things.... I found my old KA24DE tps and it plugs right in but won't bolt up as it spins the oposite direction. However, the voltage on the KA tps reads the correct voltage and the RB tps reads backwards, so as crazy as it may sound the tps is DONE CAKES!!!

Where O where can I find a series 2 tps or an interchangeable one???? PLEASE HELP!!!!!

I did a RB25 S2 swap in my R32. I see there are 3 TPS wires and 1 TPS power wire on the large incabin plug. Where should I connect these wires or should I just leave them unconnected?

it sounds like a short to ground somewhere

I did a s2 swap in my 240 and i see there were 2 tps, one was a switch and one a sensor. one goes to the main ecu but the other one went to the in cabin plug like you said. I powered the one which i believe was a blue with black or vise versa. My car starts but will not idle with the MAF connected but will rev. With the MAF disconnected it will idle but no rev.

Have you seen any of this yet, and what did you find out about those wires? One more thing, what did you do about the air valve on the bottom of the intake manifold wiring, it also goes to that same in cabin plug that had those TPS wires....right now mine is not hooked up.

Thanks for any help
