I have a P2443 code, 2007 WRX "Sec air inj. system switching viv stuck closed bank 2" any suggestion as to cause/fix?
Hi, my name is XXXXX XXXXX is most likely a bad secondary air valve, but you must trace the chart to determine this, it could be as simple as a fuse, but if the fuse is blown, suspect the cause as being a bad valve, i will post the chart below,Tim
The fault came back after a few minutes on running after I reset it - so I guess it could be a fuse - I can check that. Baring finding a blown fuse, where is the sec air valve located and cna it be replaced by me - I am pretty experienced around fuel injection systems, with the right guidance.
the valves are not hard to change, i will post the procedure below.Tim
