I replaced one of the 4 oxygen sensors, which is before the cadillac converter. I cleared the tester and drove the vehicle, and tested it again, but it reads to replace the Bank 2, sensor 1. I did not even know there was a problem with the truck, because there was no lights on saying that there was something wrong. Can you help me, should I replace the other 3 sensors? This is a Ford F150 truck. I also ordered the truck manual from this site, and it only shows 3 sensors not 4. Any help would be appreciated. I just want to get my truck to pass inspection.
