B14A1 causing other issues
 

I know there are a bunch of threads on this code but I haven't found a thread covering the problems we are having when this code gets thrown.

Car is a 15 BRZ Automatic, Sprintex 210, header, 45% E85. Tonight, we went to the track just to have fun but it turned into a frustrating night. It runs flawlessly normally with no code thrown, but when we figured out the code tripped tonight the idle RPM dropped to 500 or so, it wouldn't stall above 2k RPM wouldn't do a burnout and just driving home the car bucked and was just generally unhappy.

Anyone had similar issues and solutions?

No
that code is unrelated to the problems you are having
i suggest u log when you get that

That's why you're getting that code. I get those codes when cars are inside the shop. The sunload sensor output gets so low at night/inside that it stores a harmless error code about it in the HVAC control module.

Your car freaked out and it just happened to be in memory when you scanned the whole network, but it's not the issue you're looking for.

I'll get a log next time I can. Car runs great otherwise.
