Had probs with my 2007 Honda CR-V in Toronto last winter—70200SXSA02 code kept popping up. Tried resetting it myself but no luck. Ended up taking it to the shop; turns out it was a sensor issue. FYI, asking around in local forums helped tons. You’d be surprised how much advice you get from folks who’ve been through it before. Trust me, better safe than sorry!
I’ve got a 2007 Honda CR-V in Denver, and fiberglass issues from cold weather got me lookin’ into the codes, especially 70200SXSA02 cause the AC turned into a space heater, ya know? Check the fuse panel, maybe a loose wire. Helped a buddy once; it was the air flow sensor’s fault! Keep your hands on the wheel, haha.
