Hey everyone. I recently took my '02 (4.0 V6 2WD) to Autozone for a SES light. Codes came back P0153 (bank 2, sensor 1) and P0156 (bank 2, sensor 2). Does this mean the sensors on the passenger side, both sensors, in front and behind catalytic converter? Also, the guy at Autozone said the replacements were Bosch 15719s that I ordered from Rock Auto for only half what Autozone quoted. I don't think these are the right replacement sensors. Any help would be appreciated.
