Detailed Description

Walker Products developed this oxygen sensor as an OE-style replacement for vehicles that depend on accurate exhaust gas feedback for fuel control and emissions monitoring. The sensor is built for the exact fitment position listed in the catalog, helping maintain the diagnostic input the ECU expects. The 350-35169 part number is associated with Hyundai Creta Grand, Kona, Tucson, Venue, Elantra, Santa Fe, Sonata, Accent, and Kia Rio, Sorento, and Sportage applications.

As a wide-band sensor, it is suited to systems that require more precise mixture control than a basic switching sensor. The heated design helps the sensor reach operating temperature more quickly, while the threaded body and specified connector style support correct installation on the intended application. Walker 350-35169 is a practical choice for Hyundai Tucson and Kia Sorento oxygen sensor replacement searches, as well as other listed Hyundai and Kia models.

What It Helps Address

• Fault codes related to oxygen sensor performance.
• Poor engine operation caused by inaccurate exhaust feedback.
• Higher fuel consumption from incorrect air-fuel control.
• Increased exhaust emissions from a failing sensor.
• Malfunction indicator light illumination tied to sensor faults.

Installation Notes and Tips

Verify the listed year, make, model, and position before installation. Confirm the connector shape, terminal count, thread size, and harness length match the original sensor. Inspect the sensor wiring harness and connector for damage before replacement, since damaged wiring can shorten service life and affect ECU feedback.
