TPS % at Idle??

[LSX]

I ran the self check on the dash today and noticed at idle it shows 9% throttle... That cant be right?..... What is everyone else saying?

I've also noticed that the TPS isn't at 0% when my foot is off the throttle. Just went out and checked it and my TPS reads a whopping 19%-22% when the pedal is all the way up. No clue why, but it's never caused an issue.

Mine, idling in park, after the 30 second idle down is at 6%. I've never checked it while driving. I think 0% would mean no fuel is being sent. I looked at it the first time when I was checking my battery charge and just wondered what everthing else showed.

If its running i wouldn't think it would go to zero its got to have so much air to idle

True. It can't be closed, or no air would enter and engine would die. Anyway, it's a voltage conversion. Not everyone's TPS is going to have the same exact voltage.

I hear what you all are saying, but 9% just seemed high to me...

Not to sound ignorant here but can all models see this? Do you have to have the upgraded radio or something? I just have the base model.

[Eidolon]

Yup, all models can see this as it is not a function of your radio. With your car off, press and hold the Enter button on your steering wheel (I think it's the roller on the left, but either way it's the one you use for selecting options on the DIC), then turn your car battery on (or go all the way and start it) while holding that button. This will bring up Engineering Mode on your DIC. Then scroll down to Throttle Percent. That's it!

Mine used to be around 12% when just idling.

Dashhawk says same on mine for TPS. It also has an "Absolute Throttle Position" as well. The GXP has the Space Shuttle indicator known as "Full Throttle Up" LOL

Thanks for the help to get to that mode. Pretty nifty. I have had the car for 28 months now and never new it existed. feel like a knob but I appreciate the help.

At idle I was at 9% as well and sometimes on the highway when I would let go and coast it would actually go to 0% for a short moment. I also noticed that it went to 100% with 3/4 of the peddle to the floor so it was just interesting watching it from time to time.

when in the engineering mode, with engine not running and no foot on the throttle pedal, my V6 says 27.4% and the dealership tech says that's what the throttle sensor resets itself to for the next start. Not done the engineering mode with the engine running. Any other V6 owners getting the same % with engine off and pedal clear ?

[MAC the KNIFE]

^thread revival!! i'm not a v6, but with engine off, i believe mine reads around ~27 also. and at idle it's around 17%

and myself and a friend were shocked to see at WOT, foot hard down, it's only 88% !

[AVIDMOTION]

Mine is also 86-88% at wot, I checked with a PLX device and it too said 88%. Am I still WOT or is there some more power hidden until I can fully floor the beast. It feels floored, I removed my mats to test but still 88% with my foot buried into floor hard as I can push....
