Walker 350-64122 Oxygen Sensor for Nissan

Walker Products 350-64122 is an OE-style upstream oxygen sensor engineered for specific Nissan applications. It is built to deliver the diagnostic feedback the ECU expects, helping maintain proper engine management on covered Rogue, X-Trail, and NV350 Urvan models.

Walker Products Aftermarket focuses on application-specific engine management and oxygen/air-fuel sensors. The 350-64122 part number is matched to the correct fitment position and is designed as a direct replacement for the original sensor location.

Key Features

  • Upstream oxygen sensor for emission control system monitoring
  • Application-specific fitment for Nissan vehicles
  • OE replacement design for ECU feedback and sensor response
  • Supports accurate air-fuel ratio and exhaust monitoring
  • Walker Products 350-64122 for targeted Nissan coverage

Compatible With Nissan Models

  • Fits 2018-2023 Nissan X-Trail, Upstream
  • Fits 2018-2019 Nissan NV350 Urvan, Upstream
  • Fits 2018 Nissan Rogue, Upstream, B1S1; Al 09/2017; To 09/2017
  • Fits 2014-2017 Nissan Rogue, Upstream, Bank 1 Sensor 1

What It Helps Address

  • Check engine light related to upstream oxygen sensor faults
  • Poor engine performance from incorrect exhaust feedback
  • Higher fuel consumption caused by inaccurate sensor readings
  • Increased exhaust emissions from a failing sensor
  • Stored ECU fault codes tied to the affected sensor circuit

Installation Notes

Confirm the vehicle year, model, and upstream position before installation. Inspect the sensor wiring harness and connector for damage, since physical wear can shorten sensor life and affect operation. For 2014-2017 Nissan Rogue applications, verify Bank 1 Sensor 1 placement before ordering.
