Hey guys, proud matrix owner here. Just needed a little help to identify a problem on my matrix. A few lights popped up on my 09 Toyota matrix S, and this code right here, the thing is the lights go away after a day or two and come back after 1-2 weeks and it's the same repeating stuff and there's also the vsc off light that blinks, it's not in the picture because it was mid blink. What can I do to get this fix and how can I figure out what exactly is causing this. It says the oxygen sensor but I have no idea what's causing it, worn out sensor maybe or something worse? Thanks guys.
