Sounds like the exhaust flap perhaps? You can buy a healtec dongle to eliminate it. Why it has 3 error codes I don’t know. The only things that coudl be classed as “emissions controls” are:
1. PAIR - Secondary air injection to cylinder head
2. Exhaust flap
3. O2 sensors on pipe

Am I missing anything else?

The exhaust flap is a mechanical thing. I wonder if a shock could have caused an issue.

I ordered the Healtech ESE. I'll see if that resolves this issue.

Really wish I could get my hands on an actual KTM diagnostic tool.

Your not the only one! I would even pay KTM prices for it!

Glad it helped! 😜

I’m going to get this adapter and wire up my can bus sniffer to see if I can find any additional data I can extract…. 😬
