Detailed Description

This Walker oxygen sensor is designed for upstream exhaust monitoring on select Volvo and Land Rover vehicles, including Volvo S60, XC60, XC90, XC70, V60, S90, V90, and Land Rover LR2 applications. The heated sensor design supports faster operating temperature, while the specific-fit connector and threaded mount help match the original sensor location and ECU feedback requirements. If you are replacing a failing upstream oxygen sensor on a Volvo XC60 or Volvo XC90, Walker 350-64065 provides the application-specific replacement format needed for service work.

This part cross-references no listed aftermarket part numbers in the provided data.

What It Helps Address

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

Installation Notes and Tips

• Verify the vehicle year, model, and upstream position before ordering.
• Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation.
• Confirm the correct side and emissions specification where the fitment notes list left, right, ULEV Spec, or Excl. ULEV Spec.
• Use the threaded mounting point and connector style to match the original sensor location on the exhaust system.
• Clear diagnostic trouble codes after installation and confirm normal ECU feedback.
