hey guys, getting OBD code P0455
I replaced the gas cap and still got the code a few days later. Anyone have any other ideas?

I'd just visually check your evap canister, hoses, and purge valve for rotten, cracked or disconnected hoses and if you find nothing just take it to a shop, evap leaks can be a pain without the equipment to diagnose.

thanks, I'll give a quick check this weekend.
where is the canistor on these cars, driver side or passenger side rear?

Evap canster is behind the inner fender plastic on the passenger side. Couple of things to check if you don't want to take it to a shop, is the vacuum lines running to the purge valve on the canister. Also, your fuel filler neck grommet that goes into the tank might be torn/leaking.

Check the purge control valve, which is located near the firewall, on the air intake side of the engine below the shock absorber upper mounting plate while you're there. It has an electrical connector that routes to the PCM. Basically you need to check for signal voltage at the plug while the engine is warm & RPMs are at about 1500. The purge valve should cycle on & off at intervals. If not then look for damaged wiring or broken insulation, which could be shorting to ground or possibly corrosion in the plug/ wiring. The purge valve could also be faulty or stuck open.

Your canister will look like either:

If you cant visually indicate a fault with those vacuum lines, fuel filler neck, the charcoal canister, or the purge valve then take it to a shop. Doing the "replace everything that it could possibly be" can get expensive quick.
