I have a 'P0135: Heated Oxygen Sensor Heater Circuit Malfunction' error code

What is the part number for Bank 1 Sensor 1?
Lexus Parts isnt too helpful and doesnt reference the sensors as 'bank 1 sensor 1'

Is this the part?

Your link did not work for me.

Do you have a California spec 1997 ES300? If so you will need Air/Fuel ratio sensor, It's listed as rear.

However if you need an oxygen sensor I would recommend Denso for the Oxygen sensor Part #: 234-4622 . Because it will be just as good quality and less expensive, $49 at Amazon. Desno is the OEM for these sensors. Denso did not have A/F sensors listed on its site for 1997.

Thank you very much. Almost certain that its a TX spec car, but you never know. A lot of CA cars make it all over the US...

I believe the sticker under the hood should say if it is california spec or not, check that.
