Walker Products 250-24987 oxygen sensor for the 2011-2013 Hyundai Elantra 4-cylinder 1.8L, the 2014-2016 Elantra 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas to show how efficiently the engine burns fuel. It is made for its specific application and fitment position, and it supplies the diagnostic feedback the ECU requires.
- Narrow-band 4-W design
- Monitors the air-fuel ratio for combustion efficiency
- Electrodes made of a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-24987 oxygen sensor
- Fits: the 2011-2013 Hyundai Elantra 4-cylinder 1.8L, the 2014-2016 Elantra 4-cylinder 2.0L and other vehicles
- Position: Downstream
- Condition: New
Rough running, higher fuel consumption or emissions, or a lit malfunction indicator light can mean the sensor is failing. A damaged wiring harness or connector can be behind these symptoms too, so look both over for physical damage with the engine off and cool, and find the cause before you buy.
Fits
It is listed for a wide range of Hyundai and Kia models, among them the 2016-2018 Hyundai Tucson 4-cylinder 2.0L and the 2014-2018 Kia Forte 4-cylinder 2.0L. If your car is not named here, look it up in the "Vehicles it fits" section. This listing is one oxygen sensor for a 2013 Hyundai Elantra 4-cylinder 1.8L, which takes one in the downstream position.

Frequently Asked Questions
Is this Hyundai Tucson oxygen sensor right for the 2016-2018 Tucson 4-cylinder 2.0L?
Yes. Walker Products 250-24987 is listed for the 2016-2018 Hyundai Tucson with the 4-cylinder 2.0L, and it goes in the downstream position.
Is this the Kia Forte oxygen sensor for the 2014-2018 Forte 4-cylinder 2.0L?
Yes. Walker Products 250-24987 is listed for the 2014-2018 Kia Forte 4-cylinder 2.0L as a downstream oxygen sensor, and the car takes one.
Is the Walker 250-24987 a narrow-band or a wideband sensor?
This downstream oxygen sensor is a narrow-band design in 4-W form. It determines the oxygen content of the exhaust gas and monitors the air-fuel ratio.
What are the electrodes on this downstream oxygen sensor made of?
The electrodes are made of a gas-permeable platinum layer. A coating protects their surfaces from contamination and erosion by combustion residue and particulates.
What symptoms can a failing downstream oxygen sensor cause?
A failing sensor can make the engine run poorly, raise fuel consumption or exhaust emissions, or light the malfunction indicator light. Newer vehicles may also store a fault code in the ECU that a shop can read.
