Another CEL P0446 question

[theiceman]

always stop at the first "click"

As it becomes more contaminated you will find you cant fill the tank and the pump keeps shutting off as you try to fill it as the contaminated charcoal is plugging up the vent.

Couple of lessons here outside of all that .. it is always courteous to state the definition of the code you are fighting , don't make others go look it up since you are the one asking for help .

Secondly it is best to just stick to what you are seeing and let people comment, rather than have them confirm your theories. ( just the facts ma'am, just the facts)

As i have been a technical troubleshooter for over 40 years and tech technical troubleshooting , i thought these tips might help

cheerio.

We may all have to replace the canister one day. Is there a DIY guide available?

I haven’t seen a DIY. I replaced mine chasing down the infamous Boxster howl. It’s not hard as the canister is easily accessible from the front passenger wheel well. The real problem is that there a few variants in evap canister over the years so you need to know which part that you need. This can be decoded from your VIN. When I replaced mine it was an hour tops with most of the time spent disassembling and reassembling. I did weigh my old and new canister. The old canister weighed a whole pound more than the new canister.
