Question about 2002 Toyota Camry
O2 sensors are more of a message delivery for the ecm,replacing them,most of the time does nothing,if it said there was a lean situation,I would check the fuel filter,and fuel pump,if it said there was a rich situation,I would check the fuel pressure regulator,and give it a major tune up.
