When handed the Fail certificate for my 2002 Montero Sport 3.5L from the smog station, I went straight to Pep Boys for the Bank 2 Sensor 2 02 sensor specified on the paperwork as being faulty. With the Bosch 13801 sensor in hand, I went home and got to work. The plug didn't line up exactly with the insert, so I broke of a little plastic lip on the Bosch, and slipped it in.
Alas, the check engine light keeps coming back on. Twice I've disconnected the battery for 20 minutes. Though the memory is wiped out, the radio continues to work, and doesn't need to be rebooted with a code.
Any insight would be helpful. Thanks!
