P0146 bank 1 sensor 3 engine light wont go away.

Question

I have already replaced the sensor and after 1 day engine light comes on again.I bought the oxygen sensor from denso company- most mechanics recommend that brand because of its good quality. But I don't know if maybe that's the problem, because of not being oem has anyone had the same problems and got to solve it- please give any advice. I will really appreciateThanks

Hi there

This could be the result of the wiring from the sensor to the computer, a plugged catalytic converter or an issue with the power supply to the sensor.
