Code P2247, Bank2 Sensor1 Location

Hi,

Replacing the sensor really isn't too difficult. However, sometimes they are difficult to access because of location and can be extremely tight due to corrosion.

If you look at the pics below, pic 1 shows the exhaust system. There are a total of 4 sensors. The one you need is bank two which is the driver's side of the vehicle and it is right after the exhaust manifold and before the catalytic converter. I highlighted it in two places in the pic.

Pic 2 below shows the orientation of the engine with an arrow pointing towards the front of the vehicle. I numbered which side is bank 1 and 2.

Now here is the concern. The code indicates an open circuit to this sensor. You could have a broken wire, a damaged connector, or even a disconnected sensor, so check those things first before replacement. If everything looks good, chances are it is the sensor.

If you would like to test the sensor, here is a link that explains how:
