That HD ecm is capable of many unseen things. It might be capping the rpm to 4k ish based on the very lean heat generating mixture. Wasn't that long ago it was discovered it can run WB sensors and all you needed was to unlock the code. TTS and PV can do that. I honestly feel it hit failsafe mode. Something next to nobody could ever experience, until now maybe?Now I think we're onto something ! I saw recently an hour meter pickup wire that was pinched beneath a mounting bracket and stopped it at the time it had accrued when it was last worked on - pointed a finger right at the last guy to work on the system. Did you inspect the wiring to the sensor ? If not you might want to let H-D know it might be cut or pinched or even another wire that might have been disturbed, disconnected, cut, pinched, oil or coolant contaminated that could affect the fuel injection system. Obviously those codes are a finger pointing in the general direction of the culprit, but are they the root cause or a symptom of the root cause ? Just gotta keep inspecting, following the leads. Drain the oil filter and cut it open when you can if nothing else it'll give you piece of mind that the engines not failing internally.
