Question

p0161 infiniti.  what does code mean?  where is it located?

Answer 1

This code is for the rear o2 sensor heater on bank 1. This is the sensor behind the converter on the passenger side of the vehicle.

Typically the heater wire inside the sensor burns out so replacement of the sensor usually solves the problem
