Check engine light came on, the culprit is the o2 in Bank One, Sensor 2. Does anyone have a diagram of this to illustrate it's location? Or if anyone can explain it's location easier, that would be fine. The service manager said that Bank One is cylinders 1-3, and that Sensor 1 is in the manifold piping--then Sensor 2 is after the cat. He said the same goes for Bank 2 [cylinders 4-6]. Also--does anyone have any experience using the non-oe o2's from Advanced Auto Parts?

Thanks in advance.

 

Here you go.
