Product Details
Walker Products Engine Management and Oxygen/Air-Fuel sensors are developed as original-equipment replacement parts for a wide range of vehicles. Part number 350-34652 is built for the specified application and fitment position so the ECU receives the expected diagnostic feedback from the downstream sensor circuit. This part cross-references Bosch (e.g., 15733) for the same application.
Compatible With select 2011-2018 Hyundai Elantra, Elantra Coupe, Elantra GT, and Tucson models, plus 2014-2018 Kia Forte, Forte5, Forte Koup, and 2014-2015 Kia Rondo applications listed below. Use the exact vehicle, year, emissions configuration, and sensor position to confirm fitment before ordering.
Common Issues This Sensor May Address
- Check engine light related to downstream oxygen sensor faults
- Poor fuel economy caused by inaccurate exhaust feedback
- Higher exhaust emissions from a failing sensor
- Stored ECU fault codes tied to the affected sensor circuit
- Rough engine operation linked to incorrect air-fuel monitoring
Installation Notes
Inspect the sensor, wiring harness, and connector for physical damage before installation. Confirm the downstream location, bank/sensor designation, thread size, connector style, and emissions configuration match the vehicle. This part is listed for specific-fit applications only and should be matched to the exact model and notes shown in the fitment data.
