Had this fault code for years on the RAV4. Fault Code P1155 Faulty Lambda Sensor Bank 2 Sensor 1.

If I wanted to fix it myself, is it very difficult and can I use a non Denso sensor or should I stick to the original equipment. Any advice much appreciated, thanks!

Had same problem and it rips fuel really badly and no shouldn't matter which sensors you buy as long as it is the correct ones, make sure you get the correct ones for the right banks as they wont clip in to the connectors.

You can do them yourself they are really dead easy they screw out and then screw them back in but then you will need to delete the code and all should be working again as it should do.

Then watch your fuel be much better and the car will be allot more responsive.
