Hi .. Have a p0052 code o2 sensor bank 2 sensor 1 .. I just replaced it. Pulled the battery terminals for about 10 min. When I started the jeep the engine light was still on , never went off. Can someone please tell me why the code is still there? And did I even replace the correct sensor? Correct place ? I did passenger side, first sensor closest to the engine.. Any feed back greatly appreciated. Thanks..
