2004 n.murano 1148 code and location to fix

Question

How to fox codes p1148 & p1031 on a nissan murano 2004 & where the problem is on the vehicle

Answer 1

Hi there,

P1148 code is for closed loop function on bank 1.

P1031 code is for the O2 sensor bank 1 sensor 1. So, if you take care of this code it should resolve the other code. This is the first O2 sensor on the firewall side of the engine. It's up on the exhaust manifold and difficult to get to.
