O2 Oxygen Sensor Upstream Downstream for Nissan Murano Pathfinder (2015-2019) 3.5L

Direct-Fit Complete Oxygen Sensor Kit for 2015-2019 Nissan Murano and Pathfinder (Z52 / R52)

What it Does: The complete 4-piece oxygen sensor kit replaces degraded upstream air-fuel ratio sensors and downstream heated O2 sensors on the 2015-2019 Nissan Murano and Pathfinder to restore closed-loop fuel trim precision and clear diagnostic trouble codes.

The Stock Nissan Murano,Pathfinder Sensor Degradation

Factory lambda sensors on the transverse VQ35DE and VQ35DD powertrains operate in severe thermal cycling environments close to the exhaust manifolds and pre-catalytic converters. Over time, silica contamination, oil blow-by, and continuous thermal stress poison the internal zirconia ceramic sensing elements. This degradation leads to sluggish switching response, false lean readings, unmetered rich fuel trimming, poor fuel economy, rough idle, and persistent DTCs like P0130, P0138, P0420, or P2A00. Replacing isolated sensors often leaves mismatched impedance across engine banks, resulting in erratic ECU air-fuel management.

The Engineering Solution

This 4-piece upstream and downstream sensor kit restores factory-calibrated closed-loop air/fuel ratio feedback for both Bank 1 and Bank 2. Built with precision-engineered planar zirconia ceramic thimbles and integrated platinum electrodes, each sensor provides millivolt-level signal fidelity and ultra-fast light-off response via dual-layer protective heater circuitry. High-temperature fluoropolymer-insulated wiring harnesses, double-sealed stainless steel protective bodies, and direct-fit OEM pin-matched connectors ensure long-term resistance against exhaust vibration, thermal degradation, and moisture intrusion.

Frequently Asked Questions & Fitment Warnings

Does this fit the Z52 and R52 Murano and Pathfinder?

Yes, this is a direct fit for the 2015-2019 Nissan Murano and Pathfinder equipped with the 3.5L V6 engine. Verify engine displacement prior to purchase; this kit does not fit 2.5L hybrid configurations.

Do the threads come pre-treated with anti-seize compound?

Yes, high-temperature nickel-based anti-seize is pre-applied or recommended on the threads to ensure proper seating and prevent galling in stainless steel exhaust bungs.
