the main throttle angle TPS variable resistor, (POT.) can be 100% off, in accuracy, huge variances here, brand to brand . super easy to make them in a factory.
5000 ohms is par, (end to end pins) throttle angle pins.
what matters most is voltage out.. on the wiper pin, of the POT.
not only that but the 5vdc on the 5v pin can be 4.75 to 5.25 volts, all this is normal...
eCU limits TPS for DTC errors.
below 4% throttle angle (below about 0.2Volts) driving, you will get DTC codes 22 errors.
the normal voltage idling is 0.6 to 1.5v (see how crude that is?) The ECU does not care here. (only a fast right foot matters)
on the high side the ECU does not like voltages above, dtc 21. some where from 4.2v to 4.75v? the ECU sees this is stuck high TPS failure, code 22..
a broken ground pin sets code 22. or broken 5v power pin sets code 21.
