Walker 350-64024 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

Walker 350-64024 Oxygen Sensor Overview

Walker Products 350-64024 is a heated oxygen sensor built for specific upstream applications on select Subaru and Toyota vehicles. It is engineered as an OE-style replacement to deliver the feedback the ECU uses for fuel control and emissions monitoring.

For drivers diagnosing a check engine light, poor fuel economy, or elevated exhaust emissions, this Walker Products Aftermarket sensor provides a direct-fit solution for the correct application and position.

Key Features

• Heated oxygen sensor for upstream engine management feedback
• Specific fit design for confirmed vehicle applications
• 4-wire configuration with 20-gauge wiring
• Radiused polygon male connector for application-specific connection
• Threaded mounting with 18.0 mm thread diameter
• Wiring harness length: 18.03 in.; overall length: 21.57 in.

Application Details

Walker Products Aftermarket focuses on OE replacement engine management components, and the 350-64024 follows that approach with application-specific fitment and sensor positioning. This part number is listed for 2000-2004 Toyota Camry and Toyota Solara upstream positions, plus 2001-2004 Subaru Outback upstream right and upstream left positions. It is also listed for 2000-2001 Toyota Camry and Toyota Solara California-ESV upstream applications, and for 2002-2003 Toyota Camry and Toyota Solara upstream Bank 1 Sensor 1 positions where noted.

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

What It Helps Address

• Check engine light related to upstream oxygen sensor performance
• Rough running caused by incorrect air-fuel feedback
• Increased fuel consumption from a failing sensor signal
• Higher exhaust emissions from inaccurate ECU input
• Fault codes stored in the ECU for sensor-related issues

Installation Notes

Confirm the exact year, make, model, emissions package, and sensor position before ordering. This part is not universal, and the listed Toyota Camry, Toyota Solara, and Subaru Outback applications vary by upstream location and emissions certification. Inspect the sensor connector, wiring harness, and nearby harness routing for damage before installation, since physical wear can shorten sensor life and affect operation.

Quality Assurance

Walker Products has supplied engine management and fuel system components since 1946 and manufactures this oxygen sensor as a specific-application replacement. The brand operates under Automotive ISO9001/TS 16949 quality standards.
