I had my EML come on a while back so I bought an OBD II scanner so I could find out what was causing the light to illuminate. The code was P0131 which is the O2 Sensor, Bank 1 Sensor 2. I replaced the sensor under the hood right by the engine but the light stayed on. I have been reading up quite a bit, but no where online can I find the location of the post-cat lambda sensor? Could someone please help.

We do not have that vehicle here in the United States but that sensor will either be on the catalytic converter or right behind the catalytic converter. So you will need to raise the vehicle up and inspect the around the catalytic converter area. Hope information helps you and let us know how you do.
