P1147 2005 Nissan Maxima -

Question

Hi,

I own a Nissan Maxima 02 and
about a year ago P0456 code
show up and I did replaced the
fuel cap at the dealership.
Now the code came back and
with two more codes, P1147
and P1456.
I went back to the dealership
and they want to replace all
the sensors but I think the
problem is in just one of them
since they are related codes.
I am not sure which part to
order and where to take my
car to fix.
I live in Sherwood Park - Alberta
Canada.
Any help will be really appreciated.

Answer 1

both code are for the same sensor. Bank 1 sensor 2 oxygen sensor

if the problem is not related to an intake leak or fuel pressure issue, the oxygen sensor will have to be replaced. If it has been less than a year or 12,000 miles the parts and repair should be under warranty
