Error code P0135: Camry 1MZ-FE Air/Fuel ratio sensor replacement

[Old man]

Hi guys,

I need help to replace my air/fuel sensor on my V6 1MZ-FE engine, this sensor is located at bank 1 sensor 1 after the firewall. I do not want to remove my intake plenum again as i just replaced my knock sensor and valve gasket. Has any one change this sensor out by accessing from under the vehicle?

Code error is P0135 (O2 sensor fail bank 1 sensor 1) -i believe this is the air/fuel sensor.

Any help is appreciated.

Thanks

I have, but that was on non factory exhausts, so the location may be different.

Update- replaced it. Access is only possible from under the car. I used a 7/8 or 22mm wrench to loosen the sensor, after that it pretty easy. Cheers
