Walker 350-64119 Oxygen Sensor for Nissan

Walker Products 350-64119 is an upstream oxygen sensor engineered as an OE-style replacement for specific Nissan applications. It is built for the correct fitment position and to provide the ECU with the feedback needed for proper engine management.

• Upstream oxygen sensor for Bank 1 Sensor 1 applications
• OE replacement design for specific vehicle fitment
• Supports ECU diagnostic feedback on equipped vehicles
• Built for Nissan Sentra and Nissan Juke applications
• Walker Products Aftermarket part number 350-64119

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed for direct replacement use. Part number 350-64119 is specified for upstream placement on select Nissan Sentra and Nissan Juke models, including 2017-2019 Nissan Sentra, upstream, and 2015-2017 Nissan Juke, upstream. For 2015 Nissan Juke applications, the fitment notes include Bank 1 Sensor 1 and vehicles built from 10/2014.

This oxygen sensor is used to restore accurate exhaust feedback to the ECU when the original sensor is no longer performing correctly. A failing sensor can contribute to poor engine operation, higher fuel consumption, increased emissions, or a malfunction indicator light. The sensor, wiring harness, and connector should be inspected for damage during diagnosis.

What It Helps Address

• Check engine light related to upstream oxygen sensor faults
• Rough engine performance caused by incorrect air-fuel feedback
• Increased fuel consumption from inaccurate sensor readings
• Elevated exhaust emissions from a degraded sensor signal
• Fault codes stored in the ECU for Bank 1 Sensor 1 or upstream sensor issues

Installation Notes

Confirm the vehicle year, model, and sensor position before ordering. This part is for upstream placement only and must match the application listed for your Nissan Sentra or Nissan Juke. Inspect the connector and wiring before installation, and verify that the original fault is related to the oxygen sensor circuit or sensor performance.

Quality Assurance
