Help Nissan P2AOO CODE 2002

Hello, Nesecito helps on this p2a00 code that refers and as an exar the repair or that I must verify, in advance thanks

Hello. It is a generic code and refers to the O2 sensor circuit (Lamba probe), range/operation, sensor 1 Bank1. Therefore it would be the oxygen sensor before the catalyst. Before you can check it, you should check the installation and connectors, it is also important to verify that there are no leaks in the exhaust system. Greetings

Thank you, I will do the corresponding test.
