DB9 O2 banks and sensors

[mike-2txrc]

Hi,

Does anyone have a diagram of which banks and what sensors are where.

I have a code p2197 O2 bank 2 sensor 1 stuck lean but can't figure out which one it is.

Cheers

Here you go...As you can see, though, you'll also have to identify which ECU you're reading from, as the V12 has a "Bank 1/Bank 2" on each side. Hope this helps.

Awesome thank you.

It's saying this on the foxwell cylinder 12 bank 2 sensor 1 so will be the rear passenger side I think.

Cheers

The Fowell reads and reports on the ECU's independently: I believe it should list them as "12 Cylinder EMS-P" and "12 Cylinder EMS-S" (the P and S representing the Primary and Secondary ECUs, respectively). This means that the Primary is for the left bank, looking from the front of the car, while the right bank is Secondary (I hesitate to use "driver" and "passenger" sides as I'm in Canada). Given that, you still need to see which bank it is referring to (Primary or Secondary) but the Bank 2 Sensor 1 position is the rear pre-cat sensor, mounted near the top of the manifold - and much more easily reached than the post-cat position, mounted closer to where the mid-pipe joins the manifold.

So it states ems-s engine control module.thank you for the clarification.
