Check engine light on.

**pufdup** · 03-12-2012

My check engine light came on Friday afternoon. My Cobb AP read it as a P2443. Secondary air injection system switching valve stuck closed(Bank 2)
I can reset the ecu but it came back today. Any ideas how to fix this? My gas mileage is slipping. Was getting about 24 mpg's on 93 oct. stage 2.
Now its 19.5. Thanks!

Still have this problem. Anyone have any ideas what i need to do to fix this? It's getting to be a pain to keep resetting my ecu almost everyday.
Might be time to say bye to Subarus!!

theres pictures of where they go on the motor and youll have to remove all the air pump piping and such.

Thank you for the info. I greatly appreciate it! i do have a mechanic that works on Subies! We'll get right on it
