Walker Products 250-24779 oxygen sensor for the 2017-2019 Hyundai Elantra 4-cylinder 2.0L and other vehicles measures oxygen in the exhaust gas. Its readings give the ECU the feedback it needs to monitor combustion efficiency.
- Measures oxygen levels in the exhaust to help fine-tune the air-fuel mixture and support fuel economy
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases to help reduce pollutants
- Electrode coating protects the surfaces from contamination and erosion by combustion residue and particulates
- Narrow-band, 4-wire sensor made for its specific application and position on the vehicle
Quick facts
- Part: Walker Products 250-24779 oxygen sensor
- Fits: 2017-2019 Hyundai Elantra 4-cylinder 2.0L and other vehicles
- Position: Upstream, downstream
- Condition: New
Rough running, higher fuel consumption, more exhaust emissions or a malfunction indicator light can mean the sensor has failed. Those signs alone don't prove it, though: a vacuum leak can also upset how the engine runs, so look over the sensor, wiring harness and connector for physical damage with the engine off and cool.
Fits
The 2017-2019 Hyundai Elantra 4-cylinder 2.0L, the 2017-2024 Kia Soul 4-cylinder 2.0L and the 2019-2021 Hyundai Veloster 4-cylinder 2.0L are among the vehicles it fits. If your car isn't named here, enter its year and engine in the "Vehicles it fits" section. This listing is one sensor; each sensor position on the car takes its own.

Frequently Asked Questions
Is this the right oxygen sensor for a 2017-2024 Kia Soul 4-cylinder 2.0L?
Yes. Walker Products 250-24779 is listed for the 2017-2024 Kia Soul with the 4-cylinder 2.0L, and the fitment calls for a quantity of one.
Will this oxygen sensor fit the 2017-2019 Hyundai Elantra 4-cylinder 2.0L?
Yes. The fitment lists it for the 2017-2019 Hyundai Elantra 4-cylinder 2.0L, with a quantity of one.
Is Walker Products 250-24779 an upstream or downstream sensor?
Walker Products 250-24779 is catalogued for both upstream and downstream positions. It is a narrow-band, 4-wire direct-fit sensor.
Will a failed 250-24779 sensor turn on the malfunction indicator light?
It can. Newer vehicles store fault codes in the ECU, and some relate to the sensor and its associated systems, so a scan shows which code was set.
What is the platinum layer on this oxygen sensor for?
The electrodes are made of a gas-permeable platinum layer. A coating protects their surfaces from contamination and erosion by combustion residue and particulates in the exhaust.
