Detailed Description

The Walker Products Aftermarket line is focused on OE-style replacement sensors for modern engine management systems. Part number 350-64082 is a heated oxygen sensor designed for upstream use, where it helps the ECU monitor exhaust oxygen content and adjust fuel delivery. That makes it a direct-fit choice for emissions-related service on vehicles such as the Nissan Altima, Nissan Juke, Nissan NV2500, Nissan NV3500, and INFINITI G25.

This sensor is listed for specific positions including upstream, upstream right, and upstream left, depending on the vehicle application. The fitment data also includes California emissions and B1S1 references for certain Nissan Altima and Juke applications, which is important when matching the sensor to the exact vehicle configuration. Walker Products 350-64082 is built for the listed application, fitment position, and ECU feedback requirements.

What It May Help Resolve

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

Installation Notes and Tips

• Confirm the exact year, make, model, emissions package, and sensor position before ordering.
• Use the listed upstream, upstream right, or upstream left position only where shown in the fitment data.
• Inspect the sensor wiring harness and connector for damage before installation.
• Check for exhaust leaks or related engine management issues that could affect sensor operation.
• For Nissan Altima and Nissan Juke applications, verify California emissions and B1S1 details against the vehicle build information.
