I'll be going after a vacuum leak on the AC system soon (it's 118F here right now so not too anxious to get under the hood right now) and thought I would run the EATC self test mode in the meantime. I get a 16 and 76 displayed on the screen at the same time. These codes do not appear in my factory manual nor any google search that I can find. Does anyone have any idea what this potato of a vehicle is trying to tell me?
