Walker Products Oxygen Sensor P/N:250-24275
Walker 250-25143 oxygen sensor for the 2020-2026 Hyundai Sonata 4-cylinder 2.5L and other vehicles measures the oxygen content of the exhaust gas. This Walker oxygen sensor passes the reading to the engine computer, which monitors the air-fuel ratio for combustion efficiency.
A failing sensor can show up as rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector is another common source of those symptoms, so look both over before blaming the sensor. This listing is one sensor; the 2020-2026 Hyundai Sonata 4-cylinder 2.5L takes one.
As an oxygen sensor for the 2021-2024 Kia Sorento 4-cylinder 2.5L and the 2021-2023 Hyundai Santa Fe 4-cylinder 2.5L, it also fits a wide range of Hyundai, Kia, Audi and Mercedes-Benz models. If your car is not named here, open the "Vehicles it fits" section to find your exact model and engine.
