P1416 - Port Air Circuit Malfunction/ (AIR) System Bank 2 Look at your emissions sticker under the hood, does it say anything about California Emissions? I think this code pertains to that. In any case, bank 2 is the passenger side of the engine, and the AIR system usually has something to do with the exhaust. Look for broken hoses, vacuum lines, leaking gaskets, anything that could cause air to escape. Check your vacuum lines carefully by using a propane UNLIT propane torch and go around every single vacuum line with the engine running. If the engine rpms increases, you have found the leak. If you find nothing amiss, take it to a professional and do not just throw parts at the problem. You will be money ahead.
