P1416 is your O2 censors. ANSWER: P1416 refers to a problem in the exhaust system which is, unfortunately, very difficult to track down. Depending on who you talk to about it, you can do nothing and never have a problem or you can do nothing and it can ultimately lead to a problem with the catalytic converter. Damned if you do and damned if you don't.
Look for a leak in the port-side vacuum.

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.
That code indicates a problem with the AIR system, bank 2. Bank 2 is the passenger side of your car. It is most likely the check valve on the passenger side. It can be cleaned, or cheaply replaced.
