Walker Products 350-34081 right oxygen sensor for the 2016-2019 Hyundai Sonata 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas to gauge combustion efficiency. This Walker Products oxygen sensor is a direct-fit, narrow-band unit.
- Made for its specific application and fitment position
- Gas-permeable platinum layer on the electrodes
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
- Monitors exhaust gases to help reduce pollutants
- Provides the diagnostic feedback the ECU requires for its application
Quick facts
- Part: Walker Products 350-34081 oxygen sensor
- Fits: 2016-2019 Hyundai Sonata 4-cylinder 2.0L and other vehicles
- Position: Upstream, downstream, upstream right
- Condition: New
A failing sensor can show up as a rough-running engine, higher fuel consumption, more exhaust emissions or a lit check engine light, though other faults cause the same signs. With the engine off and cool, look over the sensor, its wiring harness and its connector for physical damage before you replace anything; a shop can test the rest. If the sensor is the cause, this one replaces it.
Fits
The 2016-2019 Hyundai Sonata 4-cylinder 2.0L, the 2011-2016 Hyundai Elantra 4-cylinder 1.8L, the 2014-2017 Elantra 4-cylinder 2.0L and the 2018-2021 Hyundai Tucson 4-cylinder 2.0L each take one sensor, and so do many other vehicles. As a Hyundai Sonata oxygen sensor replacement for the 2016-2019 4-cylinder 2.0L, it is a direct-fit unit, and this listing is a single sensor. If your car is not named here, look it up in the "Vehicles it fits" section.

Frequently Asked Questions
Is this the right oxygen sensor for a 2014-2017 Hyundai Elantra 4-cylinder 2.0L?
Yes. Walker Products 350-34081 is listed for the 2014-2017 Hyundai Elantra 4-cylinder 2.0L and the 2011-2016 Elantra 4-cylinder 1.8L, one sensor per car.
Is this the Hyundai Tucson oxygen sensor for the 2018-2021 Tucson 4-cylinder 2.0L?
Yes. Walker Products 350-34081 is listed for the 2018-2021 Hyundai Tucson 4-cylinder 2.0L, one sensor per vehicle. Other vehicles are in the "Vehicles it fits" section.
What thread size does this narrow-band oxygen sensor have?
This sensor has an M18 - 1.5 thread and is a narrow-band design.
Can a failing oxygen sensor turn on the check engine light?
Yes. A failed sensor can light the check engine light, and it can also come with rough running, higher fuel use or more emissions. A shop can read the stored codes.
What does the coating on the Walker oxygen sensor electrodes do?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases. The electrodes carry a gas-permeable platinum layer.
