Situation: Wife got this car last month and 2 weeks later the SES light came on. I had the code pulled and it's P1446 evap canister closed. We live in AZ and the commute to work includes a 10 mile dirt/gravel road. I took it to the dealer last week and they put a new evap valve and filter kit for free as a one time goodwill deal. Next time it'll cost around $400 they said. Got it back, drove it to work, and the following day the SES light came on again. I think the filter kit is clogged up.
My question now is: What other things should I look at concerning the evap system? I've read that folks have had the filter moved to the engine bay and a 12 ft hose going from that to the evap valve. Will this help my Path from getting clogged up? Living in a hot and dusty area, I'd like to make this as dust proof as possible. Also, there's some nice dirt roads I'd like to take this off roading to and I don't want to cause any damage by not prepping adequately. Any advice and help is appreciated.
