bank 1

if this helps, bank 1 is whichever side of the engine your #1 cylinder is on. of course, since this is a 4-cylinder, it's not that hard to find...

The code scanner will say bank x sensor y. bank x sensor 1 is in front, and bank x sensor 2 is in the back.

I work at auto zone and pull at least 15 check engine codes a day.
just some useless information if anyone needs it in the future.

sorry, I accidentally posted this in response to the check engine light question in the forum. it was supposed to be a reply, not a new thread.
