Detailed Description

This Facet oxygen sensor is intended for rear-position exhaust monitoring on select Hyundai Accent, Hyundai Veloster, Kia Rio, and Kia Soul models. The rear sensor helps the engine management system evaluate catalyst performance and maintain accurate emissions-related readings. If you are replacing a worn rear O2 sensor on a 2012-2016 Hyundai Accent or 2012-2015 Kia Soul, Facet 10.8346 provides the correct application match by year, make, model, and position.

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

Common Issues It May Address

• Check engine light related to rear oxygen sensor performance
• Fault codes tied to catalyst efficiency monitoring
• Delayed or inaccurate exhaust feedback to the engine control system
• Emissions test failures caused by a failing rear sensor
• Rougher fuel control behavior when sensor output degrades

Installation Notes and Tips

Verify the connector style, sensor location, and engine application before installation. Use the vehicle’s service information to confirm the rear sensor position and clear diagnostic trouble codes after replacement. Inspect the exhaust threads and wiring routing during service to avoid damage to the new sensor.

Quality Assurance

Facet is an established name in emission control components, and part number 10.8346 is cataloged for the listed Hyundai and Kia rear sensor applications.
