  • What does this sensor/code mean?

    I just changed my spark plug wires yesterday, so I know I probably knocked a sensor wire loose. Today, the third drive since I finished my wire job, I got a check engine light. Autozone scanned it and it read three codes, 1133 and two 1406's.

    P1406 manufacturer control auxilary emission controls
    P1133 fuel air metering.

    Assuming it's just a wire I knocked loose, and not a worse problem, what sensor should I expect it to be? Any other ideas what I might have done?

        actually, mine is getting the p1406 manufacturer control auxilary emissions controls also. i took it to auto zone and checked it there. their equipment might call it something different however, the meanings are basically teh same in a sense.
        basically from what i have been told, more than likely it is clogged canister/catalyst system or just a bad sensor
