Engine lights come on and the engine runs hard. I connected a OBD2 reader and got the following error code (See image).

 

Where is this sensor located, and how can I change this myself? Did not find out with the help of google. It is a 2010 model Avensis t27 with 2.0D engine.

I have received price offers from two different workshops. One will have $ 350 to fix it, the other will have $ 1600 if the diagnosis is correct, and the part loosens without problems. If this is an easy job I would like to do it myself, but I need help finding out where the sensor is on my car.

This may be of help.  It shows the location of the air/fuel ratio sensor.  The part number is 89467-20100.
