Walker 350-34495 Oxygen Sensor - Downstream

Walker 350-34495 Oxygen Sensor for Honda S2000

Walker Products 350-34495 is a heated oxygen sensor built as a specific-fit OE replacement for the downstream position on select 2006-2009 Honda S2000 models. It is engineered to provide the ECU with the feedback needed for accurate fuel control and emissions monitoring.

Key Features

• Specific-fit oxygen sensor for downstream bank 1 sensor 2 applications
• Heated sensor design for faster operating temperature
• 4-wire configuration with female connector
• Threaded mounting type with 18.0 mm thread diameter
• 24.13 in. wiring harness length and 22-gauge wire
• Radiused polygon connector shape for application-specific fitment

Product Details

Walker Products Aftermarket 350-34495 is part of the Walker Products Engine Management line, which focuses on OE-style replacement sensors for vehicle-specific applications. This oxygen sensor is made for the downstream bank 1 sensor 2 location on 2006-2009 Honda S2000 models, helping the engine management system monitor exhaust output and maintain proper diagnostic feedback. The 27.68 in. overall length and threaded mounting design support direct replacement where the original sensor uses the same configuration. Walker Products 350-34495 is a practical choice when servicing a Honda S2000 oxygen sensor circuit that has triggered fault codes or drivability concerns.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

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

Installation Notes

Verify the connector shape, wire count, thread diameter, and downstream bank 1 sensor 2 location before installation. Inspect the sensor wiring harness and connector for heat damage, corrosion, or abrasion, since physical damage can shorten sensor life. Confirm the vehicle application against the 2006-2009 Honda S2000 fitment listing before replacing the original part.

Quality Assurance

Walker Products manufactures engine management sensors as OE replacement parts for specific vehicle applications and operates as an ISO 9001/TS 16949 certified company. The Walker Products Aftermarket line is built around application-specific fitment and diagnostic feedback requirements for modern engine control systems.
