Could be bad or poor fuel cause detonation.

Did the set sensor come unbolted? Mine did once and threw the same code. Find bolt, locktite in on back side under the head (it's a pain to get to in the bulkhead)

Chase the thick black wire from the set sensor to Ecu and see if it came disconnected or is shorting

I agree...check the DET sensor, if it is lose or fell off it can throw a code. I guess if DET is the issue you could try running a higher octane like 100LL to see if that stops it. This happened on mine and I thought I had fixed and it came back again, the sensor had come lose yet again. I used clear nail polish (tip from a Navy Aircraft mech) and it's never come out again.

If you aren't careful and zip tie the sensor wires back, it will rub on the jackshaft and short out giving you that error. Happened to mine the first year I had mine. Pull your seat and tank off and locate where it is attached to the ECU and follow it back to the head and chances are you will see it grooved out by the jackshaft running on it. If that isn't it then is just came loose possibly.
