Question Trying to work on my own car

Iím new to this so just let me know if I am posting this in the wrong place.

Hello, Iím very new to working on my own car I have a 06 wrx with some mods. My car has been sitting for 6 months, before I stopped driving it I was getting multiple codes.
P0244 Turbocharge wastegate solenoid A range/performance
P2441 Secondary air injection system switching value stuck closed bank 1
P2443 Secondary air injection system switching value stuck closed bank 2

I know my wastegate is getting stuck closed at times, I have checked my actuator and think I should check my solenoid next but am unsure how I do that. I do have a ohm meter, do I have to take the solenoid out of the car? And I have no idea how to fix/check the air injection system, I did clear the codes and drive the car a little today to see if Iíd get them again and I got nothing but I also didnít push my car at all.
Thank you all so much

06? do yourself a favor and look into removing the air injection system if you (if not in emissions nazi state). Totally worthless system. (functionally and from an emissions standpoint even)
You can remove a bit of it or alot of it, i'd recommend as much as you want to go through with the work for.

Don't quote me, but iirc, 244 code is generating by over-boosting (according to ecu settings). Is your car tuned? might want to find out if you don't know. Back off your wastegate performance a bit if so. Or adjust other parameters to account for that kind of boost if thats what you want to run. WG solenoid is easy enuf to get to, but they dont go bad often, more likely WG acuator or part of the vacuum system. For instance if we're troubleshooting a stock car, i'd be checking/just replacing the vac lines between the solenoid and WG acuator. They get brittle and crack to easy with the heat where they're at.

Not saying it is the best place, the most accurate place, or that it should be your sole source of information, but Youtube is a great place to start.

Find your engine code (EJ??), chassis code (e.g. GV) and search away.

Watch a few videos so you know what some of the processes are and have a decent feeling for what you are about to do.

Check your specific engine code forum on this very site and use the Search function above the right most column. Be specific in your search term as this site has a lot of information that is broadly organized/categorized. It will take a while to did through all/most of the threads, but you should find snippets of what can help. You aren't the first person to have these issues/codes.

If need be, make a copy/paste Word document (or similar) to give you a run down of the necessary steps/procedures if you can't have a digital device near you when doing the dirty deed.

Make sure you have enough of the right tools and or replacements pieces/parts to minimize/mitigate trips to the store because, and I know this for a fact, nothing ever goes as planned when taking the car apart and putting it back together.


In a car of your age, vacuum lines are definitely at a point of failure. If you rent a smoke machine, or build your own (again, see Youtube), you might find that you have more than one failed/damaged vacuum line/connector.


Depending on your city/county/state inspection laws, I'd 2nd removing the air injection system as much as possible or install a catch can or air-oil-separator to minimize/eliminate the oil vapors getting back into the intake so they can be "burned" for the sake of emissions while causing other issues to arise.

Watch, read, and learn lots. Always take the highest safety precautions, to include EYE PROTECTION, and wrench away. Always support the car with STANDS or RAMPS if you are going to be under it and don't forget to chock a wheel to prevent unnecessary rocking.

Finally, document your adventures, and if you are in a sharing mood, share you story/process here to further the community.

Happy wrenching.
