Lexus LX450 Dignostic code P0133

[Kamran Khan]

Hi Every one,
This morning when I started my Lexus Lx450 I saw engine light came on and when I checked it with OBD 2 scanner. It showed " O2 sensor circuit slow response bank 1 sensor 1 Error code P0133".

I google but didn't find a solid answer. My question is, what is the part number that need to be replaced, is it on driver side or passenger side. I think sensor 1 is upstream correct me if i am wrong.
Please help me find the part number So I can order it. Thanks!

Before you order anything, check the connections of the O2 sensors, clear the codes and wait for it to come back.

If it does, follow the FSM's testing procedures and replace if necessary.

Great suggestion, is this sensor located on driver side or passenger side?

Both O2 sensors are located on the passenger side.

Upstream is on the Y-pipe before the primary cat and downstream on the muffler pipe after the secondary cat.

Can be bought from Amazon or Denso website.

OEM Sensor that is made by Denso and sold by Toyota is 130 $.

And those who need downstream sensor, that means bank 1 sensor 2.
Part number is:
Denso 234-4153 Oxygen Sensor

Both of these sensors can fit Toyota Land Cruiser FZJ80 or Lexus LX450.
