I'm trying to find out what my throttle position should read at with key at ON position and car off in neutral and also in first gear. Can someone check what their car reads? Much thanks

tps is not gear dependent. it measures how far you have depressed the gas. what exactly are you trying to do?

I'm trying to find out if what I'm reading is correct under the conditions listed because with one throttle connected I'm getting 15% on neutral - 16% first gear and steady idle . Plug in passenger side TB and get 18% - 19% and idle from 1500-2500 up and down. Idle relearn does not work so trying to find out if its a bad TB.

TPS is a measurement of the throttle body sensor. APP is the pedal position (which I think you have mixed up). The two are loosely related but there is a difference based on gear, rpm, wheel slip, and plenty of other things.

Thanks I know this, but I was just pointing out exactly what I'm reading when I have the car off but with Key at the ON position with driver TB plugged in and changing the gears from neutral to 1st without hitting the gas. My Gas Pedal position is always 0% with foot off the gas.

Just was wondering if someone with an Accessport or Osirus or some other obd tool that can read TPS could let me know what theirs is reading.

No one on here can check what their throttle position is with the key at ON position?

Mine reads 0.0 with car not running and 0.4 after starting.

Quick Question was this in Percent or Volts ?

each car is different. That's why there is a TPS and APP learn on the haltech to get the exact voltage of your TPS and APP for it to function correctly.

The computer can move the throttle position (the 18% or whatever you are seeing) to keep the car idling. It isn't the same as the pedal position (APP, accelerator pedal position) like someone else stated.
