o2 sensor P2A00 code help

[350znut]

Hi 350z lovers,have any of you had any experience with changing your o2 sensors and have you stuck with original Nissan parts?,

we have an HR Z showing P2A00 code,bank 1 sensor 1,we bought a denso replacement but after 50 miles the code has returned,so was thinking of using a Nissan part instead...im losing patience at a vast rate

have you tried swapping the left and right hand bank sensors over to see if it actually is the sensor and not another issue
