EVAP Purge Valve Issue??

    I've had a check engine light on for a while now. It's throwing out the following codes: P0449 and P0496. Both of these refer to an issue with the EVAP system. I pulled the purge valve located near the fuel tank and cleaned it out, which didn't fix it, but I do hear a rattle when I shake it, so I'm thinking this is the source of my problem. If I replace that and it doesn't fix it, I'll move to the solenoid under the hood.

    Fixing/replacing these parts isn't my issue. I'm just wondering if not fixing this issue right away will do any kind of damage to my truck. I'm about to go on a long road trip, and I don't have time to order the replacement parts before I leave. If I wait until I get back, will I be hurting my truck in any way?? Please help! Thanks!
