Walker Products 250-25166 center oxygen sensor for the 2011-2013 Hyundai Elantra 4-cylinder 1.8L and other vehicles measures the oxygen in the exhaust gas to report combustion efficiency. This Walker Products oxygen sensor is a wide-band unit made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it needs.
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Reads the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Electrodes made of a gas-permeable platinum layer
- Oxygen readings help fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
Quick facts
- Part: Walker Products 250-25166 oxygen sensor
- Fits: 2011-2013 Hyundai Elantra 4-cylinder 1.8L and other vehicles
- Position: Center, upstream, downstream
- Condition: New
A failing sensor can show up as an engine that runs poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Before you replace it, look over the sensor, its wiring harness and the connector for physical damage with the engine off and cool, because damage there can shorten a sensor's life.
Fits
It is listed for a wide range of Hyundai, Kia, BMW, Audi and Volkswagen models, including the 2012-2016 Kia Soul 4-cylinder 2.0L, and it is an oxygen sensor for the 2014-2017 BMW X5 6-cylinder 3.0L. This listing is a single sensor, and the quantity per vehicle is one. If your car is not named here, look up its year, make and model in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for a 2012-2016 Kia Soul 4-cylinder 2.0L?
Yes. Walker Products 250-25166 is listed for the 2012-2016 Kia Soul 4-cylinder 2.0L, and the quantity per vehicle is one.
Does this oxygen sensor fit a 2013 Hyundai Elantra 4-cylinder 1.8L?
Yes. Walker Products 250-25166 is listed for the 2011-2013 Hyundai Elantra 4-cylinder 1.8L, which includes the 2013 model year.
What are the electrodes made of in this wide-band oxygen sensor?
The electrodes are made of a gas-permeable platinum layer. A coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust.
Can I keep driving with a failing wide-band oxygen sensor?
Have it checked or replaced promptly. A failed sensor can make the engine run poorly and raise fuel consumption and exhaust emissions.
What does this oxygen sensor actually measure?
It measures the oxygen content of the exhaust gas and monitors the air-fuel ratio for combustion efficiency. The ECU gets the diagnostic feedback it needs from these readings.
