2000 ES300

I have error codes P1130 and P1135, referring to the A/F sensor Bank1,Sensor1.

Is this the sensor attached to the manifold (in front of vehicle, under hood).

Or is this located under the car? has anyone changed this and successfully cleared the codes?

Thanks,

Under the car, Bank 1 is the manifold in the rear. Sensor 1 states that it is before the Catalytic converter. Replace sensor, and disconnect the battery to clear the code.

Here's a photo of the area from my RX300, similar 1MZFE motor as your ES300.

you will need an o2 sensor socket to remove it, trust me, it is almost impossible to remove without it
