I had the same code come up on my Hawk wrx '56.
Simple job to do,
Remove I/C.
Trace back from secondary pump you'll see a t piece and hoses. Remove them.
Undo the brackets on the valve and 2 bolts going into the engine block. (watch out for metal gasket)!
Valve assembly should be free. Undo screws and spray liberally with Carb cleaner.
Put everything back on.
I'm not a genius at mechanics and even with my chip shovel hands I managed to do it in an hour. Never had a problem with it since and that was nearly a year ago.

Yeah too right. The heat had even made the black rubber seal in the centre bubble slightly. I probably should replace the seal but because the valve on it's own is so expensive I'm looking to map out the secondary air system next time the car is in. Lots to read up on about the topic on websites. You might need some reading glasses after haha.
Hope it goes ok.

In the photos is that the secondary air pump? Did you do anything with the airpump valves? The actual code on mine is secondary air pump
VALVE stuck open. Does the pump connect to the valve?
