    Hello. Did you install an OEM O2 sensor or aftermarket? Sometimes you need an OEM sensor for it to work properly. However, there are no other trouble codes? The P0133 code can also be triggered when there is something wrong with the air-fuel mixture.

    Check for vacuum leaks, exhaust leaks if there are no other trouble codes!
