Intermittent Fault

I haven't taken the values at maximum or pedal released but all at about 2000 rpm. The driver demand 1 was 1.7v and 2 was 3.85v
 
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
 
The only voltage I could get off Hawkeye was MAF at 2.05v and intake air sensor at 2.68v. I'll get under the bonnet tomorrow evening to check AAP and MAP.
 
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
 
For those last two readings I removed the plugs and took the voltage with a meter at the plug itself. Wouldn't that be the supply to the sensor or am I getting mixed up?
 
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
