I replaced the TPS (OEM brand new) but had no knowledge back then that it has to be at a certain parameter.
While Ignition is OFF, I back-probed top (positive - sensor wire) and bottom (negative) wires on the TPS by inserting two tiny needles/pins and attaching those to a volt meter.
Then turned the ignition on and had 0.54 V Fully closed. At fully open throttle, I got 3.77 V. I adjusted the idle voltage to 0.62 V and that made the fully open throttle voltage to 3.89 V. An immediate difference I noticed: A random vibration (about 10-15 second intervals) at idle I had before was no more. Too early to confirm, but something I noticed.
Let me know if you know the exact voltage at sensor wire on TPS at idle please.

At Wot it's 3.5V- 4.7 volts.
