Hi guys

What TPS voltage do you record @ idle?

Do you know what the service manual stated what it should be?

On my MY03 STi (type UK, ECU AH990-5512), it appears these 0 and 100% values are learned by the ECU after a reset (and maybe rescalled on a regular basis...?).

On my car this afternoon :
0%........ 0.84v
100% ... 4.20v

Ok. Looks good.

I am wondering if the TPS wasn't set properly, what the problems could result.

I look forward to rs tps readings and JDM models, since I have a JDM.
