Nissan Repair: Nissan maxima dtc P1147, oxygen sensors, nissan maxima

Question
I have a 2002 Maxima with code P1147,I'll like toknow how can I fix this problem ny self, thanks in advance  

Answer
The code P1147 is a heated oxygen sensor on bank 2.
The easiest way to replace this is to order it first from the parts store and then get the proper tool to remove it from the exhaust system.
There are usually two of these oxygen sensors.
One located under the hood on the exhaust manifold.
The other is located just before or after the catalytic converter (I believe this is the bank 2 but you may want to verify this with your parts store)
Usually a pretty quick fix.
Thankyou for your question.
