30% Pedal Travel = WOT??
The title hints a bit of what I'm seeing but I have a 14 sti and I was messing around with the Cobb accesport and ran across the throttle position. So I curiously wanted to see what my typical drive home was like with throttle usage. However I quickly noticed something weird while sitting in the parking lot. I had the engine off and was messing with the pedal. To my surprise it showed 100% and I still had 70% of travel left. Is this a bad sensor or a legit reading and if so why? Thanks for the help.

sounds like the factory setting, at least in a 15+. id bet the 14 has the same goofball type setup to make people think the car is more responsive than it is.

yeah, this is the modern age electronic throttle where they calibrate it go from 0 to 100 in a fraction of the actual pedal travel.
I guess people with zero clue about cars like this idiotic feature, but actual car enthusiasts generally don't like it since it sucks. I wish I could change mine to be like a real throttle where it goes from 0 to 100 over the full pedal travel |

Thats just the throttle position sensor mapping based on sport, sharp or sport sharp. This tuning trick was available in the 80's for turbo ford 2.3's as a plug in piggy back modification to the TPS, where it would open the throttle further than the actual pedal position under your foot to make it "feel" more responsive. In your case though if you floor the gas it should still open 100% regardless of the setting you are in if you are driving normally at speed....if you are in neutral or doing something else out of the ordinary and then FLOORING the gas pedal, its possible the ECU may limit the throttle body openning to prevent engine damage. So if you are doing it with the engine off, that is not normal operation hence why you are getting those readings,,,my guess here is it limits the throttle body in case you try and start the engine in or out of gear with the pedal floored as I do know it will cut the fuel in the scenario to prevent engine flooding and cylinder wash.
