Half throttle lights Service..

Hello,

My 2006 G1100 has had an Issue for a few years that I can´t seem to shake.

When riding at less than half throttle, like 90 Kph but on the same throttle position it lights up the Service light and message. After turning off and on again the ignition it dissapears.
If I ride without holding the throttle steady it won´t happen.

last time it showed up I accessed the diagnosis menu without turning the engine off to check the dash and panel errors and it had the 21 and 4 active and the 1, 2, 5 and 6 were flashing.

Turned off the switch, turned on again and ran the diagnosis, same codes. Deleted the errors and, still the same.

The Tps was reset and the throttle bodies were sinchronized, the engine is running smooth and the fuel comsuption is better, but these errors won´t dissapear, I really don´t know what else to do, Is it possible that the original map is somehow damaged? should I try a new map?

01 Immobiliser fault: key code read but not recognised or key code not read
02 Key not present or transponder broken
05 Fuel sensor fault
06 Air temperature sensor fault

I'd look for issues in these areas first.

It's not the map. Error 21 is lambda probe.

Check & reseat the dash connectors and the O2 sensor as a first step.

It could be the lambda sensor.
