Hi all,

currently have my CEL on, P0057 code popped in my scanner.

upon searching the forums, I can’t seem to find the part code for a 2014 Lexus IS250 F Sport (Canadian).

Info on the web is conflicting, Rockauto points to “downstream left” Is that the right part to order? Also, what would be the part number just to be sure?


Thanks in advance

Code P0057 is for Bank 2 Sensor 2.
Bank 2 is the Driver's side of the engine (left side).

Assuming your vehicle is AWD, you would be looking for the Downstream Left AWD sensor...if you're looking at Rockauto's site.
The Upstream sensors are the Air Fuel Ratio sensors.

The Oxygen Sensor part numbers all start with 89465...I'm not sure what the last 5 digits are though.

Thanks for your help.

Replaced both downstreams. Luckily, the right sensor’s wiring was exposed was getting corroded and was probably going to throw a code soon.

So both left and right are replaced and codes are gone!
