Walker 350-64072 Oxygen Sensor

Walker 350-64072 Oxygen Sensor for Nissan and Suzuki

Walker Products 350-64072 is a heated oxygen sensor built as a specific-fit OE-style replacement for select Nissan, Infiniti, and Suzuki applications. It is engineered to deliver the ECU feedback needed for accurate fuel control, emissions monitoring, and fault-code diagnosis.

Key Features

• Heated oxygen sensor with 4-wire design
• Specific fit for the listed upstream positions
• Threaded mounting with 18.0 mm thread diameter
• Radiused polygon male connector for vehicle-specific connection
• 13.31 in. wiring harness length and 16.85 in. overall length
• Walker Products Aftermarket line for OE-style engine management replacement

Detailed Description

The Walker Products Aftermarket line focuses on engine management and oxygen/air-fuel sensors developed for direct replacement use across many vehicle platforms. Part number 350-64072 is built for upstream sensor locations and is listed for applications such as the Nissan Armada, Pathfinder, TITAN, Altima, Versa, Frontier, Rogue, Xterra, Maxima, INFINITI QX56, and Suzuki Equator. This part number 350-64072 is also listed for select Bank 1 Sensor 1 and front sensor positions where specified.

As an upstream oxygen sensor, it helps the ECU monitor exhaust oxygen content so the engine can maintain proper air-fuel control. For Nissan Armada and Nissan TITAN upstream right or left applications, as well as Nissan Altima upstream Bank 1 Sensor 1 coverage, the fitment is application-specific and position-specific for the listed vehicles.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Poor fuel economy caused by incorrect exhaust feedback
• Rough engine operation from inaccurate air-fuel correction
• Elevated exhaust emissions from a failing upstream sensor
• Fault codes stored in the ECU for sensor or related system issues

Installation Notes and Tips

• Confirm the exact year, make, model, and upstream position before ordering.
• Verify whether the vehicle is California emissions certified, since some listed Altima and Rogue applications exclude California-ESV vehicles.
• Inspect the sensor, wiring harness, and connector for heat damage or physical wear before installation.
• Use the threaded mounting point and connector shape to match the original sensor layout.
• For Nissan Pathfinder, Armada, TITAN, Frontier, Xterra, and INFINITI QX56 applications, match left or right upstream placement exactly as listed.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and operates as an ISO 9001/TS 16949 certified company. The Walker 350-64072 is manufactured for the specified application and fitment position to support the diagnostic feedback expected by the ECU.
