The diagnostics screen shows adjustments and general operation... it can look good there and still be bad.... because TPS's are finicky when they start to act up... check everything else, and if you can narrow it down, just go buy a new one... hard to diagnose properly.
Backprobing is possible, and monitoring while you ride if you like. That would be more likely to reveal issues, if any. If you see any "jumping" of your meter in the lower throttle openings, then time for e new one.
Here's what one looks like inside, ceramic resistor tracks with four little fingers following the track... you'd wonder how they fail (this one was a bad one I did surgery on for a member here). At the right light angle you can see the tracks.....
