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's a generic code and refers to the O2 sensor circuit (lambda sensor), range/operation, sensor 1 bank 1. Therefore, it would be the oxygen sensor before the catalytic converter. Before replacing it, you should check the wiring and connectors. It's also important to check for leaks in the exhaust system. Regards.

Thank you, I will do the corresponding test.
