dp213 Posted September 4, 2016 Share Posted September 4, 2016 My friends wrx threw a code (p0410) secondary air valve? I've done a little research and it seems that it can be a pain. Is a system delete a smart possibility? Link to comment Share on other sites More sharing options...
Bushwick Posted September 4, 2016 Share Posted September 4, 2016 No delete if it gets emission testing. I'd investigate what went wrong and repair. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted September 5, 2016 Share Posted September 5, 2016 there's a long thread about the issue at NASIOC. I used RomRaider and ECU flash to kill 14 codes on my 06 . both valves are stuck closed and have been for years. There are still in place but I pulled a fuse and a relay. No issue with emissions testing. (folks with valves stuck open have more work to do.) Your 07 needs to have a sensor divorced from one of the valves if you remove it. There's no evidence Subaru improved the replacement s parts and they are expensive. read here; http://forums.nasioc.com/forums/showthread.php?t=1209260 1 Link to comment Share on other sites More sharing options...
wtdash Posted September 5, 2016 Share Posted September 5, 2016 Just to add to the above, RomRaider and ECUFlash are both free software you can download and run on most Windows-based laptops. You need a special Tactrix cable to connect to the car's OBD2 port. In this case, find someone local that does tuning and they can turn off the code.. Don't expect it be free, but likely much cheaper than trying to fix one of Subaru's design mistakes from the factory. td Link to comment Share on other sites More sharing options...
