P2030 check engine light with Banks Automind 2

I recently installed a Banks Automind 2, and for the most part things have been really good. Fuel mileage while towing a 32' tag along enclosed trailer did improve, but I don't seem to be able to stay out of the throttle when I'm not towing to get better mileage.

About a week ago, I wasn't towing, and I pulled out onto a service road with a good bit of throttle application. Immediately I got a check engine light. I pulled the code with the Automind and it's a P2030. I cleared the code, and all was good until today when I did another very heavy throttle acceleration from a standing start, and the same check engine light came up.



I did some research after the first incident, but there is very little info out there. This is the most informational stuff that I was able to find: https://www.yourmechanic.com/article...ed-heater-perf


Has anyone run into this issue? Search results here resulted in nothing.

I would verify that’s the true code you have. Some readers do a very poor job. That’s not a common code. Could be P203D or something else.
