Walker Oxygen Sensor for Nissan Altima and Rogue

Walker Products 350-34467 is a heated, specific-fit oxygen sensor engineered as an OE-style replacement for select Nissan applications. It is built for downstream use and provides the ECU with the feedback needed to monitor exhaust and emissions performance.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for confirmed Nissan Altima and Nissan Rogue applications
• Downstream mounting position for post-catalyst monitoring
• 4-wire configuration with a radiused polygon male connector
• Threaded installation with 18.0 mm thread diameter
• Walker Products Aftermarket part number 350-34467

Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors built for direct replacement use. Part number 350-34467 is manufactured for the specified application and fitment position, helping restore the diagnostic signal the ECU expects from the downstream sensor circuit. For Nissan Altima and Nissan Rogue models, this oxygen sensor is used in emissions monitoring after the catalytic converter, where accurate feedback supports proper system operation and fault-code diagnosis.

This part number 350-34467 is a practical choice when servicing a downstream oxygen sensor on a Nissan Altima or Nissan Rogue with the listed emissions configuration. It is designed around the application-specific connector, harness length, and threaded mount so the replacement matches the original sensor layout.

What It Helps Address

• Check engine light related to downstream oxygen sensor faults
• Poor fuel economy caused by inaccurate exhaust feedback
• Elevated exhaust emissions from a failing sensor circuit
• Rough engine operation tied to incorrect ECU sensor input
• Diagnostic trouble codes stored for the affected emissions system

Installation Notes and Tips

• Confirm the vehicle’s emissions package and sensor position before ordering.
• Verify downstream placement and connector style against the original sensor.
• Inspect the wiring harness and connector for heat damage, abrasion, or corrosion before installation.
• Check for exhaust leaks or catalyst-related issues that could affect sensor readings.
• Use the vehicle’s service information to confirm the correct bank and sensor location.
