Nissan Repair Questions? Ask a Mechanic for Answers ASAP
There is a technical service bulletin for these 2 codes.
Basically Nissan will reprogram the ecm and get the sensor back into parameters. There is a fee for this work, but since you have replaced the sensor already, it should be done and something you should consider.
the bulletin # ***** *****
I have had a lot of success with this reprogramming to resolve this particular code.
I believe some shops have the ability with the right scan tool, so I would call around. I have only worked at the dealership so I am not that up to date on aftermarket scan tools.
You likely didn't even have to replace the sensor to be honest.
The labor is .8 hours to have the computer reprogrammed. I would start there. It is possible that you may also have a converter issue, but you need to start here.
HERE is a link to the bulletin.
They don't always, but if the sensor isn't working it's not going to. The sensor tells on the converter. That's basically it's job in a round about way. I am only giving you a heads up that it could come to that. One step at a time, taking care of getting rid of this first code is the first step. Then once that is done wait and see if the converter code comes up. If not, then it's golden.
They should, it doesn't have to be registered to work on it.
Please let me know if there is anything else I can do to help.
Also, please remember to rate my answer.
The bulletin covers both banks, the 2 codes you have are also both bank so yes, we are talking about the same thing. The reprogramming changes the parameters for the heaters on the O2 sensors so it will run in loop.
Sorry for the delay, lost my internet connection last night.
