Hello my name is ***** ***** thank you for your question.

That code indicates the Bank 2 Catt Converter is not functioning. You get this code when the 02 sensors are working. So you will need to replace the Catt Converter to resolve your issue.

Nissan Mechanic: Jay, Nissan Technician replied 4 months ago

Allot of people think this code is caused by a 02 sensor when it's not. You get this code when the 02 sensors are working and the catt converter is not.

cats already changed,code comes back within 20 miles,bank 2 is passenger side?
Nissan Mechanic: Jay, Nissan Technician replied 4 months ago

Did you replace the Catt Converter with a After Market one?

Ask Your Own Nissan Question
Nissan Mechanic: Jay, Nissan Technician replied 4 months ago

Most after market catt converters are not made with the proper material to convert exhaust gases. So if that is the case, you would continue to get Catt Codes.

Ask Your Own Nissan Question
Nissan Mechanic: Jay, Nissan Technician replied 4 months ago

So if you already have a after market Catt installed, if you can get a 02 sensor spacer for the rear 02 sensor, they are around 30 bucks or so. Install one of them to pull the rear 02 out of the exhaust stream and you can fool the computer to think the catt is working so you won't get the code any more.

Would you like a picture of a 02 sensor spacer example?
