I have the following codes po410 and po491.......can u please tell me what they are so I can get my car fixed asap


P0410 - SECONDARY AIR INJECTION (AIR) SYSTEM
P0491 - SECONDARY AIR INJECTION (AIR) SYSTEM INSUFFICIENT FLOW (BANK 1)

Secondary air injection (trademarked as Air Injection Reactor) is a process where fresh air is injected into the exhaust system to allow for a fuller combustion of exhaust gasses.

The possible causes are:
SAIR pump low or now air flow
SAIR bypass solenoid leaking/blocked or stuck open/closed
SAIR diverter valve leaking/blocked or stuck open/closed
SAIR air hose restriction
SAIR vacuum hose restriction or leaking

Check to make sure your air filter isn't dirty - and replace if needed. Otherwise I would suggest having your local trusted auto repair facility diagnose and repair the issue. A scan tool will be needed to properly diagnose the issue.
