And what voltage you see on other sensor's supply ?

I meant other sensor's supply voltage like MAP or AAP which shuld also get the same supply like the TPS and if those have the same voltage means that the ECU delivers a bit lower supply for all

Doesnt hawkeye show MAP and AAP supply voltage onlive data?

I somehow remembered that hawkeye displayed the MAP and AAP sensor's supply too but it seems i was wrong, those are the sensor outputs not the supply and at idle those are OK, i wanted to see other sensor's supply too to compare with the TPS supply if you see what i mean

If you took the reading across the earth and supply of the MAP sensor then that 2.5 is bad, AAP and MAP/IAT should have 5V supply from the same ECU output(KP wire) and the same 5V should get to the TPS too cos it's from the same internal source, check voltage against vehicle earth too
