P0153 code for Maxima 2K

it means you need to get it to the dealership and get it fixed for free if you have less than 80k miles on it

Thanks for your response. I've got about 87,500 miles, so I guess it won't be for free. The dealer won't give me much information except that he can only tell after charging a $70 diagnostic fee.

then tell the dealership to replace the effected oxygen sensors and flash the ECM.

And tell them that you will pay no more than 2.0 labor hours plus parts , take it or leave it. Chances are they will take it.

if not get in and drive away.

If I remember my "banks" correctly, Bank 2 is the left bank of cylinders - the 3 closest to the front of the car, also known as the left bank. The O2 sensor for that bank (in the Y-pipe) that needs to be replaced.

NissTech, I've seen several instances where the 5th Gens need ther ECMs flashed, some for the O2 sensors and some for MAFs. I was wondering if you knew if the updates affect the map or just the sensitivity/thresholds before a sensor is detected as failed?

I took a look at checkers auto to figure out which oxygen sensor to buy. There seem to be several options at

I think bank 2 it the one on the left or closest to the radiator.

the sensors are different depending on if you have a California spec car, or a rest of the USA model.

Nissan won't give us that information, but my gut tell me that the logic used to determine a failing part is relaxed a bit.
