Walker 350-34498 Oxygen Sensor - Downstream

Walker Oxygen Sensor for Suzuki Esteem

Walker Products 350-34498 is a heated oxygen sensor built as a specific-fit OE replacement for select Suzuki Esteem applications. It is engineered to provide the ECU with the feedback needed for proper fuel control and emissions monitoring on downstream positions.

Key Features

• Specific-fit oxygen sensor for select Suzuki Esteem models
• Heated sensor design for faster operating response
• 4-wire configuration with female connector
• Threaded mounting type with 18.0 mm thread diameter
• Wiring harness length: 18.03 in.; overall length: 21.57 in.
• Radiused polygon connector shape for application-specific fitment

Product Details

Walker Products Aftermarket 350-34498 is part of the Walker Products Engine Management and Oxygen/Air-Fuel sensor line, developed as an OE-style replacement for vehicle-specific applications. This sensor is made for downstream use on select 1995-2000 Suzuki Esteem models, including Fits 1995 Suzuki Esteem, downstream and Fits 1996-2000 Suzuki Esteem, downstream. When the original sensor begins to age or fail, the ECU may log fault codes and the vehicle can show poor running behavior, higher fuel use, increased exhaust emissions, or a malfunction indicator light. Walker Products 350-34498 is built to match the required fitment position and diagnostic feedback for the application.

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
• Rich or lean fuel mixture concerns
• Reduced fuel economy caused by inaccurate exhaust feedback
• Higher exhaust emissions from a worn sensor
• Driveability issues tied to faulty ECU sensor input

Installation Notes

Verify the connector style, threaded mounting location, and downstream position before installation. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion, since physical damage can shorten service life. Confirm the vehicle application by year, make, model, and sensor position before ordering.

Quality Assurance

Walker Products has been manufacturing engine management components since 1946 and operates as an Automotive ISO 9001/TS 16949 certified company. The 350-34498 is produced as a specific application replacement for the listed Suzuki Esteem fitments.
