Is cylinders 1-3 on the driver's or passenger's side?

[tracke30m3]

I've searched but can't find an answer, which side is cylinders 1-3?

I'm getting code P1119 on my OBD2 scanner, I read about switching the O2 sensors to confirm if it is a faulty sensor that's causing the CEL. Should I expect a P1115 or a P1117 code after I switch between the left and right side pre-cat sensors?


Thanks.
