Detailed Description

Walker 350-34617 is an OE-style oxygen sensor for vehicles that require accurate exhaust feedback to the ECU. It is used in applications such as 2000-2011 Hyundai Accent, 2001-2008 Hyundai Elantra, 2006-2011 Kia Rio, 2010-2011 Kia Soul, and other listed fitments. This part number is also referenced for select Dodge Attitude and Dodge Verna applications, making it a practical replacement when the original sensor has failed or is no longer responding correctly.

As a heated sensor with a threaded mount and application-specific connector layout, Walker Products 350-34617 is intended to match the original sensor position and signal requirements. For buyers searching for a 2009 Hyundai Elantra downstream oxygen sensor, a 2006-2011 Kia Rio upstream oxygen sensor, or a 2005-2009 Hyundai Tucson downstream oxygen sensor, this part number aligns with the listed OE replacement applications.

What This Sensor Helps Address

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

Installation Notes and Tips

Confirm the vehicle year, make, model, and sensor position before ordering. This part is listed for both upstream and downstream locations, so match the application to Bank 1 Sensor 1 or Bank 1 Sensor 2 as required. Inspect the sensor wiring harness and connector for damage before installation, since damaged wiring can shorten sensor life and affect signal quality.

For fitment-based searches, this part covers applications such as Fits 2000-2011 Hyundai Accent, upstream and downstream; Fits 2001-2008 Hyundai Elantra, downstream; Fits 2006-2011 Kia Rio, upstream and downstream; and Fits 2010-2011 Kia Soul, downstream.

Quality Assurance

Walker Products has produced engine management and oxygen/air-fuel sensors since 1946 and operates as an ISO 9001/TS 16949 certified company. The 350-34617 is manufactured for specific application fitment and ECU feedback requirements. This part cross-references Walker Products Aftermarket 350-34617 for the same application.
