Walker 350-64085 Oxygen Sensor

Walker 350-64085 Oxygen Sensor Overview

Walker Products 350-64085 is a heated, specific-fit oxygen sensor engineered for direct replacement in select Acura, Subaru, Toyota, and Lexus applications. It is built to deliver the ECU feedback needed for proper fuel control and emissions monitoring, including upstream sensor positions on vehicles such as the 2014 Acura ILX and 2002-2006 Toyota Camry.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for the listed vehicle applications
• Threaded mounting with 18.0 mm thread diameter
• 4-wire configuration with 20-gauge wiring
• Radiused polygon male connector for application-specific connection
• Wiring harness length: 5.43 in.; overall length: 8.98 in.

Product Line Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed as OE-style replacements for a wide range of vehicles. The 350-64085 follows that approach with application-specific fitment and sensor feedback calibrated for the vehicle’s ECU, making it a practical replacement for upstream oxygen sensor service on Subaru Legacy, Subaru Outback, Subaru Tribeca, Subaru B9 Tribeca, Toyota Camry, Lexus ES300, and Acura ILX models.

Detailed Description

The Walker 350-64085 oxygen sensor is designed for upstream installation where accurate exhaust-gas feedback is required for fuel trim control and emissions monitoring. As an OE replacement-style sensor, it is matched to the listed position and connector style so the vehicle’s diagnostic system can read the sensor signal as intended. This part number is used across multiple applications, including Fits 2014 Acura ILX, upstream; Fits 2008-2009 Subaru Legacy, upstream right and upstream left; Fits 2006-2009 Subaru Outback, upstream right and upstream left; Fits 2008-2009 Subaru Tribeca, upstream right and upstream left; Fits 2006-2007 Subaru B9 Tribeca, upstream right and upstream left; Fits 2002-2006 Toyota Camry, upstream front; and Fits 2002-2003 Lexus ES300, upstream front. Walker Products 350-64085 is a direct-fit option for drivers replacing a failed upstream oxygen sensor on these vehicles.

What It Helps Address

• Check engine light related to upstream oxygen sensor faults
• Rough engine operation caused by incorrect air-fuel feedback
• Increased fuel consumption from inaccurate sensor readings
• Elevated exhaust emissions from poor mixture control
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Confirm the vehicle’s exact year, model, and sensor position before ordering Walker 350-64085. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation, since damaged wiring can shorten sensor life and affect signal quality. This part uses a threaded mounting design and is intended for the listed upstream positions only. For fitment verification, match the connector shape, wire count, and sensor location to the original unit.

Quality Assurance

Walker Products manufactures engine management sensors under ISO 9001/TS 16949 quality systems and has supplied automotive components since 1946. The 350-64085 is built as an application-specific replacement for the listed vehicles and positions, with feedback characteristics intended to meet ECU requirements.
