Re: check engine light

Make sure that the air pump is still functioning and that your hoses are in good condition.

See if this will help you.

The pump can get water in it and freeze, as well as other problems, causing the codes P0410 and P0481. The pump should run when it's first started. Have you checked all of the fuses? There's quite a bit to the system. All of the codes are for the AIR system.
