How to replace oxygen O2 sensor on 2011-2017 Nissan Quest

Replacing the oxygen sensor on a Nissan Quest costs about $40-$50 and requires 30 minutes to 1 hour of labor. Before you start replacing the oxygen sensor you need to identify which oxygen sensor needs to be replaced.

Nissan Quest will have at least two oxygen sensors. One is upstream B1S1 of the catalytic converter, and one is downstream B1S2. In the following tutorial, we will show you how to replace the upstream sensor (Bank 1 Sensor 1).

The procedure is the same for the downstream O2 sensor (Bank 1 Sensor 2). For the downstream sensor, you will find it easier to access the O2 sensor from underneath the car. 

Symptoms

When the oxygen sensor fails on your Quest, you may notice some or all of the following issues: 

  • Check Engine Light is ON
  • Decrease in fuel economy
  • Engine Hesitation or misfire
  • Rough Idling
