i have not touched anything to do with throttle pos sensor and what are the methods for fixing this

[T04GTR]

obtaining a wiring diagram for the atessa and making sure its throttle signal is seeing 0.4volts at idle. or checking that the tps is putting out 0.4 volts at the sensor its self. (middle wire)

and has it got an aftermarket ecu?

Hi, I have same 21 fault code. Signal is alive from both pins out of the ecu, but on the other side, ets side, one of both is dead. Does someone knows what is the harness layout, or has layout pictures in order to help hunting the faulty wire or connector location?

Find the R32 GTR wiring diagrams I posted to these forums a couple of years ago.
