2007 Lexus LS460 - looking for DIY instructions to replace an O2 sensor. The fault code is P2238 - Powertrain 2) O2 Sensor Positive Current Control Circuit Low Bank1 Sensor1

Any help would be greatly appreciated!

 

did you figure this out was there any symptoms that made you pull the codes.

 

Check the attached files.

 

I changed the bank 1 sensor 1 I still have check engine light check vsc system on dash also obdII isn’t reading any data from sensor one 1 even after replacing it
how did you fix yours.

 

These are key files and diagrams for anyone attempting to replace bank 2, sensor 1 O2 sensor. I will be trying to replace mine on Sunday. I'm hoping for a shortcut but either way it needs to be replaced.

 

Would these files also work on a 2007 IS250 RWD?

 

I doubt it since it's a different engine.

 

Check the condition of the wires going into the connector, those terminals can go bad and wires can be loose inside the connector.

 

I'm curious, did you have to remove the steering links and panels or did you find a work around?

Did you use an OEM replacement sensor?
