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.
have the same problem?
