06 WRX, 52,xxx miles. I have P2433, P2431, & P2444 all showing right now. I haven't taken it to the dealer after reading that they want $1300-$1600 to fix. Also seen that it will prolly fail again even if they do 'goodwill' warrenty fix on it. I've found blocking plates for about $40 and if I can get someone to delete the codes I'm hoping this eliminate my problem. Any thoughts or advice would be cool, this thread is old so PM me with any responses.
