Walker Products 250-241276 oxygen sensor for the 2020-2026 Hyundai Sonata 4-cylinder 2.5L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. This Walker Products oxygen sensor is made for a specific application and fitment position, and it sends the diagnostic feedback the ECU expects.
- Narrow-band, 4-wire direct-fit design
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Electrodes made of a gas-permeable platinum layer
- Measures oxygen levels so the air-fuel mixture can be fine-tuned, which helps fuel economy
- Monitors the oxygen content of the exhaust gas to help reduce pollutants
Quick facts
- Part: Walker Products 250-241276 oxygen sensor
- Fits: 2020-2026 Hyundai Sonata 4-cylinder 2.5L and other vehicles
- Position: Downstream
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Worn spark plugs, an exhaust leak or a damaged wiring harness can produce those signs too, so find the real cause before buying. This listing is one sensor, and the downstream position takes a single one.
Fits
The 2016-2018 Kia Sorento 4-cylinder 2.0L, the 2016-2020 Sorento 4-cylinder 2.4L, the 2019-2020 Sorento V6 3.3L, the 2021 Sorento 4-cylinder 2.5L and the 2019-2020 Hyundai Santa Fe 4-cylinder 2.4L are among the many vehicles this oxygen sensor fits.

Frequently Asked Questions
Is Walker Products 250-241276 the right Hyundai Santa Fe oxygen sensor for the 2019-2020 Santa Fe 4-cylinder 2.4L?
Yes. Walker Products 250-241276 is listed for the 2019-2020 Hyundai Santa Fe 4-cylinder 2.4L as a downstream oxygen sensor, with one sensor per application.
Is this the right Kia Sorento oxygen sensor for a 2019-2020 Sorento V6 3.3L?
Yes. Walker Products 250-241276 is listed for the 2019-2020 Kia Sorento V6 3.3L. For another Sorento year or engine, look it up in the "Vehicles it fits" section.
Is this a narrow-band or wideband oxygen sensor?
Narrow-band. This downstream sensor has four wires and a direct-fit design.
What does the coating on this oxygen sensor do?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes are a gas-permeable platinum layer.
What happens when a downstream oxygen sensor fails?
The engine can run poorly, fuel consumption and exhaust emissions can rise, and the malfunction indicator light can come on. Newer vehicles may also store a fault code for the sensor in the ECU.
