It is listed for downstream, downstream front, downstream rear, and downstream right positions depending on the vehicle and build date. This makes it a direct-fit choice for owners searching for a downstream oxygen sensor for 2013-2014 Nissan Altima, a rear downstream oxygen sensor for 2012-2014 Nissan Murano, or a downstream right oxygen sensor for 2014 INFINITI QX60.\u003c\/p\u003e\u003cp\u003eAs an OE-style replacement, this sensor is intended to provide the ECU with the feedback needed for emissions and fuel-control monitoring. Walker Products notes that a failing sensor can contribute to poor engine operation, higher fuel use, increased exhaust emissions, and a malfunction indicator light. The brand also emphasizes checking the sensor, wiring harness, and connector for physical damage when diagnosing the system.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eDownstream oxygen sensor fault codes\u003c\/li\u003e\n\u003cli\u003eMalfunction indicator light related to the exhaust sensor circuit\u003c\/li\u003e\n\u003cli\u003eRough engine operation caused by inaccurate sensor feedback\u003c\/li\u003e\n\u003cli\u003eIncreased fuel consumption from a degraded oxygen sensor\u003c\/li\u003e\n\u003cli\u003eElevated exhaust emissions from a failing downstream sensor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Fitment\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFits 2013-2021 Nissan NV200, downstream bank 1 sensor 2\u003c\/li\u003e\n\u003cli\u003eFits 2015-2018 Chevrolet City Express, downstream bank 1 sensor 2\u003c\/li\u003e\n\u003cli\u003eFits 2015 INFINITI QX60, downstream right, to 09\/2014\u003c\/li\u003e\n\u003cli\u003eFits 2015 Nissan Pathfinder, downstream right, to 09\/2014\u003c\/li\u003e\n\u003cli\u003eFits 2015 Nissan Quest, downstream rear, to 08\/2014\u003c\/li\u003e\n\u003cli\u003eFits 2014 INFINITI QX60, downstream right\u003c\/li\u003e\n\u003cli\u003eFits 2013-2014 Nissan Altima, downstream front\u003c\/li\u003e\n\u003cli\u003eFits 2012-2014 Nissan Murano, downstream rear\u003c\/li\u003e\n\u003cli\u003eFits 2012-2014 Nissan Murano, downstream front\u003c\/li\u003e\n\u003cli\u003eFits 2013-2014 Nissan Pathfinder, downstream right\u003c\/li\u003e\n\u003cli\u003eFits 2012-2014 Nissan Quest, downstream rear\u003c\/li\u003e\n\u003cli\u003eFits 2013 INFINITI JX35, downstream right\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eVerify the connector, mounting location, and build date before installation.
