I would like help in understanding what these codes mean for an S70 1998. I am new to this and I have already paid through through the nose for repairs. Everytime that I get something fixed the engine light comes on again for a new issue.
Codes P440, P410,P455

 

The 0410 code is for the air pump system Do you hear the air pump come on first thing in the Morning?

The 440,455 are for the evaperative system. The gas cap might be loose or the seal bad.

Also here is a link to a site with the codes.
