Oxygen Sensor Replacement: P2247

Oxygen Sensor Replacement: P2247
(E90 330I 2006 BMW)

This time I am going to tell you about Error code P2247, which is Bank 2, Sensor 1.

It actually gave a "Check Engine Light", I plugged in my error code reader, and it actually also gave me error code P0155, as well as P2247.

Replacing an Oxygen Sensor is not very complicated, but it does require a special tool.  An Oxygen Sensor removal tool, you can borrow from Autozone, if you buy the Sensor from there.  Here is a picture of what I got:

NOTE:
you have to run the car To Temperature for the car to recognize that it's a new Oxygen sensor: 
- I ran my car for about 5 minutes,
- Turned the car off, and back ON
- Then cleared the code
If you try to clear it too soon, it will not work.  Be patient.

Which sensor is Bank 2 Sensor 1: It is the sensor that is closer to the firewall, on top of the engine.  Pre Catalytic converter.

NOTE: 
Bank 2 Sensor 1 is : Gay color (cable harness) (Code P2247)
Bank 2 Sensor 2 is Black Color (cable harness)  (Not sure what code is)

Faul codes

Note the color of the cables on Sensor 1 and sensor 2.  Bank 1 and 2.

Remove Heat Shield:
To get to the Bank 2, Sensor 1, you have to remove this (Heat Shield):

You have to remove this, otherwise there is no room to put tool on the sensor

Don't touch the sensor part of the Sensor, it comes covered with plastic

New sensor comes with Anti-seize, ready to install:

Connecor

Note the Length too, it's not a short wire harness, NOTE it's gray color.

Bank 2 sensor 1, is the one on the left, to disconnect.
You can follow it back to see which one it is.  If you are not sure.
