04 Camry O2 Sensor location help, pics included Sign In

Hi,

I have a 2004 Toyota Camry 3.0L. Today the engine light came on so I went auto zone and got fault code: P2197 - Oxygen or A/F sensor stuck lean - bank 2 sensor 1. I assume I just have to replace the sensor the fix the problem. According to a crappy diagram I think I found bank 2 sensor 1 but could someone help me confirm this? The one I think it is, is in plain sight right behind the radiator. Also I want to buy an oem sensor but there are two, a front and rear. What kind should I get? Thanks. Here are the pics:

you could have 3 or 4 O2 sensors, bank 1 sensor 1 , bank 2 sensor 1. then depending on your application you can have a single rear after the catalytic converter or double rear.

do you know which sensor the code is for?

Rob; Bank two, sensor one, would be the upstream sensor on bank two. (cyls. 2,4, & 6) Viewing from the front of the engine, bank two will be the right side.
(sensors two are the downstream sensors, after the cats)
