Walker Products 350-34331 oxygen sensor for the 2015-2019 Hyundai Sonata 4-cylinder 1.6L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is made for the downstream position and gives the ECU diagnostic feedback.
- Monitors the air-fuel ratio to track combustion efficiency
- Measures oxygen levels to help fine-tune the air-fuel mixture and support fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
- Electrodes with a gas-permeable platinum layer
Quick facts
- Part: Walker Products 350-34331 oxygen sensor
- Fits: 2015-2019 Hyundai Sonata 4-cylinder 1.6L and other vehicles
- Position: Downstream
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. Several other faults produce these symptoms too, so with the engine off and cool, start by looking over the sensor, wiring harness and connector for physical damage.
Fits
As a direct-fit oxygen sensor replacement, it covers the 2015-2019 Hyundai Sonata 4-cylinder 1.6L, the 2017-2020 Hyundai Elantra 4-cylinder 1.4L and the 2017-2026 Elantra 4-cylinder 1.6L, and the 2012-2020 Kia Soul 4-cylinder 1.6L. This listing is one sensor, and a car needs a single one in the downstream position. For any other car, look up your make, model and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Is this Hyundai Elantra oxygen sensor right for a 2017-2020 Elantra with the 4-cylinder 1.4L?
Yes. Walker Products 350-34331 fits the 2017-2020 Hyundai Elantra 4-cylinder 1.4L and the 2017-2026 Elantra 4-cylinder 1.6L, in the downstream position.
Will this work as a Kia Soul oxygen sensor on a 2012-2020 Soul with the 4-cylinder 1.6L?
Yes. This listing is one downstream sensor for the 2012-2020 Kia Soul 4-cylinder 1.6L, which takes one.
Is the Walker Products 350-34331 a narrow-band oxygen sensor?
Yes. Walker Products 350-34331 is a narrow-band, 4-wire oxygen sensor with an M18 - 1.5 thread, made for the downstream position.
Do newer cars store a fault code when an oxygen sensor fails?
Yes. Newer vehicles store fault codes in the ECU, and some relate to the affected sensor and its associated systems. A shop can read them.
What is the coating on this oxygen sensor's electrodes for?
The coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gas. The electrodes have a gas-permeable platinum layer.
