Scangauge wrongly reports TPS@16?
 

On a 96 Intrepid, SG is reporting TPS at 16. But the throttle is not depressed and the butterfly is closed...:confused:
Whats going on?

My Santa Fe is 13 or more idling. It's just a marker number.

Yeah? And I think your Santa Fe is brand new so right on, its just a marker number. No worries then, hmm.

My Focus is also 16 at idle. It has to be open a little bit to allow enough air through for the engine to idle. On some cars, this scale starts at zero, but it's never really closed all the way unless it has a separate idle circuit.

2000 2.0 Jetta

a/c off - TPS = 3
a/c on - TPS = 5-6

Max TPS = 75

Think the Flea's idle TPS is around 13.

14-16 is usually the default value on DCXs

TPS on the sable was at 16. but I changed it to 18, car had more power right off idle and got the same mpg.

Baseline Figures
 

You need to establish the baseline at zero throttle and full throttle:

Hondas (IIRC) generally are 9-92% TPS (zero = 9, and WOT = 92). Each vehicle's user has to adapt to the similar output numbers.

Yes... and this can be checked engine off.
