Walker 350-34130 Oxygen Sensor - Downstream

Walker 350-34130 Oxygen Sensor for Nissan Cube

Walker Products 350-34130 is a heated downstream oxygen sensor built as a direct-fit OE-style replacement for specific Nissan Cube applications. It is engineered for the correct fitment position and ECU feedback, helping restore accurate exhaust monitoring on California emissions vehicles.

Key Features

• Heated oxygen sensor for downstream placement
• Specific-fit design for the correct Nissan Cube application
• 4-wire configuration with a male connector
• Threaded mounting type with 18.0 mm thread diameter
• Wiring harness length: 12.32 in.; overall length: 15.87 in.
• Radiused polygon connector shape for application-specific fitment

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors engineered as OE replacement parts for a wide range of vehicles. The 350-34130 is designed for downstream use on Nissan Cube models, including 2011 Nissan Cube, downstream B1S2 California-ESV applications, and 2012-2014 Nissan Cube downstream California emissions configurations. If you are replacing a failing downstream oxygen sensor on a Nissan Cube, this part number provides the application-specific fit and sensor feedback expected by the ECU. Walker Products 350-34130 is also referenced as a direct replacement for the same application in California emissions-equipped Nissan Cube vehicles.

Common Issues This Sensor Can Address

• Check engine light or malfunction indicator light related to oxygen sensor performance
• Poor engine operation caused by inaccurate exhaust oxygen readings
• Increased fuel consumption from incorrect air-fuel feedback
• Higher exhaust emissions from a degraded downstream sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the vehicle is a 2011-2014 Nissan Cube with the correct downstream California emissions or California-ESV application before ordering. Inspect the sensor wiring harness and connector for damage during diagnosis, since physical wear can shorten sensor life and affect readings. Use the threaded mounting location and connector style to verify match-up with the original part before installation.

Quality Assurance

Walker Products manufactures engine management sensors as OE replacement components and operates as an ISO 9001 / TS 16949 certified company. Since 1946, the Walker Products Aftermarket line has been focused on engine management and fuel system components for vehicle applications worldwide.
