Product Details

Walker Products Aftermarket focuses on engine management and oxygen/air-fuel sensors developed for OE replacement use across many global vehicle platforms. Part number 350-34615 is application-specific, meaning the sensor position, connector style, and harness layout are matched to the listed fitments for proper ECU signal reporting. This matters on modern vehicles where the oxygen sensor plays a direct role in fuel control, emissions monitoring, and fault-code diagnosis. This part number 350-34615 is listed for multiple positions, including upstream front, upstream rear, downstream front, downstream left, downstream right, and upstream left on select Hyundai and Kia models.

Compatible With: 2006-2010 Hyundai Sonata, 2007-2009 Hyundai Santa Fe, 2007-2012 Hyundai Veracruz, 2007-2012 Hyundai Entourage, 2006-2011 Hyundai Azera, 2009-2011 Hyundai Genesis, 2010-2012 Hyundai Genesis Coupe, 2006-2010 Kia Sedona, 2007-2009 Kia Amanti, 2007-2009 Kia Sorento, 2009 Kia Borrego, and 2010-2011 Kia Borrego. This part cross-references no listed interchange numbers in the provided data.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rough engine operation caused by incorrect exhaust feedback
• Increased fuel consumption from inaccurate air-fuel readings
• Elevated exhaust emissions from a failing sensor
• Stored ECU fault codes tied to the affected sensor circuit

Installation Notes and Tips

Verify the exact position before ordering, since this sensor is used in multiple upstream and downstream locations. Inspect the sensor wiring harness and connector for heat damage, abrasion, or corrosion before installation. For best results, confirm thread size, connector shape, and harness length against the removed part.
