Walker 350-34468 Oxygen Sensor - Upstream

Walker 350-34468 Oxygen Sensor for Honda Fitment

Walker Products 350-34468 is a heated oxygen sensor built as a specific-fit OE-style replacement for select Honda applications. It is engineered to provide the ECU with the correct feedback for air-fuel control, helping maintain proper engine management on vehicles such as the Honda Civic and Honda S2000.

Key Features

• Heated oxygen sensor for faster operating response
• Specific-fit design for the listed Honda applications
• 4-wire configuration with male connector
• Threaded mounting type with 18.0 mm thread diameter
• Wiring harness length: 19.21 in.; overall length: 22.76 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. Part number 350-34468 is built for upstream placement and is listed for 1998-2000 Honda Civic and 2000-2003 Honda S2000 applications. This sensor is intended to deliver the diagnostic signal the ECU expects, making it a direct-fit choice for drivers searching for an upstream oxygen sensor for Honda Civic or an upstream oxygen sensor for Honda S2000. The Walker Products 350-34468 oxygen sensor uses a heated design, threaded mounting, and application-specific connector geometry to match the listed vehicles.

What It Helps Address

• Check engine light related to upstream oxygen sensor faults
• Poor fuel control caused by inaccurate exhaust feedback
• Increased fuel consumption from a failing air-fuel sensor
• Higher exhaust emissions from incorrect ECU input
• Rough engine operation tied to sensor signal degradation

Installation Notes and Tips

Fits 1998-2000 Honda Civic, upstream. Fits 2000-2003 Honda S2000, upstream. Confirm the connector shape, wire count, thread diameter, and sensor position before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life and affect signal quality. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

Walker Products is an ISO 9001/TS 16949 certified automotive manufacturer with a long history in engine management components. The 350-34468 is produced as an application-specific replacement sensor for the listed Honda fitments and is backed by Walker Products’ established OE-replacement engineering approach.
