Other day my SES light came on, took it to autozone to have it hooked up and pull the code from it.. came back P0440 emission control systems. Anyone have any idea what this could possibly be? thanks

there might be a leak in the EVAP system. make sure your gas cap is on tight.

I had the same thing, they said that it was either the gas cap not sealing or my fule sencer, and with further inspection they said it was the sencer in the tank
