P0031 Nissan - Service Engine soon Light

Question

Hi
I have a 2009 SL Nissan rogue. I have got service engine soon light on.
After diagnosing with Autozone I found following
a. P0130
b. P0031
c. P1148

I tried it with one of the auto-mechanics' , After reading the codes he concluded oxygen sensor has the problem without even checking the car.
I am curious and feel may be it is not, it could be a short circuit or something else.
I have tried resetting the service engine soon light twice, but it came back within minutes.

If the oxygen sensor really has a problem, then can you help me estimate the cost of replacing it or can you suggest an alternate solution

Thanks in Advance

Answer 1

Most likely bank 1 sensor 1 is bad.

 

Denso makes the factory sensor

if you are in California you will need part number denso 234-9071 $100 on amazon

if you are out side of California you will need denso 234-9070 $77 on amazon or denso 234-9073 $80 on amazon

labor might be any where from $30 to $60
