Default Re: Typical TPS range ? - 2005 non-turbo - 210k mi

This thing really has us stumped…! I checked it all out again today and all seems rock solid, except for the %... !
The sensor resistance is exactly 5K ohms across the leads, and there's no ‘bounce’ or flakiness when viewed on a mini-scope (DSO), and the voltages were very repeatable (max=3.75V & giving 75% value at the throttle-motion hard-stop limit, 0.25v at idle position)…

PS If anyone has a live data scanner & wants a fun, easy experiment, and to maybe share their results, it would be incredibly helpful to know what max throttle % others get when they push their accelerators to the floor, and when it’s released - no need to even start the car or to drive around….!! : )

Here’s HOW: ...Just hook up the scanner, put the key in the ignition to the run position, find the “TPS” parameter from the live data list, press the gas pedal to the floor & note the maximum % the TPS gets (and maybe note the minimum % when the pedal is released..?) and report back here with what you found… : )) …
EASY..!

...Our TPS doesn't get above 75% or lower than 15.5%. Some drive cycles need the computer to see 85% throttle, so there’s a problem…

Before we spend $128 on a new, OEM TPS that may do just what mine is now, we’re thinking of going to the salvage yard tomorrow & picking up a few TPS’s for comparison & tryout, to see if “investing” in a new OEM sensor is likely to change anything for the better. Its likely the cars are in the salvage yard aren't there due a broken TPS !! :Lol )

Stay tuned…! As always, thanks for any help or insights shared…! : )

Many needed repairs / worth it / kinda fun... includes control arm, steering rack & K-frame member {each at a different time-!} - self and with local friendly mechanic.

Most notable mod is installing an AirLift(tm) Kit inside the rear springs (for the Boat / trailer !)...
