I have a 2003 toyota rav 4 and have replace 3 sensors. The 2 lower downstreams and upper left side upstream and I still get the code p1155 bank 1 sensor 2. Any ideas how to fix the problem I used bosch for the upstream and densco for the downstreams. Could it be the brand bosch that is not working.

The brand shouldn't matter. Check to make sure the wiring and plug to the sensor is in good condition. They get damaged, corroded, and I've seen them melt from exhaust heat.
