Walker Products 350-35031 oxygen sensor for the 2009-2012 Hyundai Sonata 4-cylinder 2.4L, the 2011 Sonata 4-cylinder 2.0L and other vehicles reads the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a wide-band unit made for its specific application and fitment position, and it returns the diagnostic feedback the ECU expects.
- Measures oxygen levels so the air-fuel mixture can be fine-tuned for fuel economy
- Monitors exhaust gases to help reduce pollutants
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Electrodes made of a gas-permeable platinum layer
- Tracks the air-fuel ratio to show combustion efficiency
Quick facts
- Part: Walker Products 350-35031 oxygen sensor
- Fits: 2009-2012 Hyundai Sonata 4-cylinder 2.4L, the 2011 Sonata 4-cylinder 2.0L and other vehicles
- Position: Upstream, downstream, upstream left, upstream right
- Condition: New
A failing oxygen sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light, and newer vehicles may store fault codes. Those signs can have other causes. With the engine off and cool, look over the sensor, wiring harness and connector for physical damage, which can shorten a sensor's life. If the sensor is the cause, this part replaces it.
Fits
It also works as a 2012 Hyundai Sonata oxygen sensor on the 4-cylinder 2.4L, and as an oxygen sensor for the 2021-2026 Hyundai Elantra 4-cylinder 1.6L and the 2017-2019 Kia Soul 4-cylinder 1.6L. The quantity is one per vehicle, and this listing is a single sensor. If your car is not named here, enter its year and engine in the "Vehicles it fits" section.

Frequently Asked Questions
Will a Hyundai Elantra oxygen sensor like this fit a 2021-2026 Elantra 4-cylinder 1.6L?
Yes. Walker Products 350-35031 fits the 2021-2026 Hyundai Elantra 4-cylinder 1.6L, and that engine takes one sensor.
Is this a Hyundai Sonata oxygen sensor replacement for a 2009-2012 Sonata 4-cylinder 2.4L?
Yes. Walker Products 350-35031 fits the 2009-2012 Hyundai Sonata 4-cylinder 2.4L and the 2011 Sonata 4-cylinder 2.0L, one sensor each.
What is the electrode coating on this oxygen sensor for?
The electrodes are a gas-permeable platinum layer. A coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
What can a failing wide-band oxygen sensor cause?
It can show up as rough running, more fuel use or a malfunction indicator light. A shop can read any codes stored in the ECU.
Which sensor positions is Walker Products 350-35031 listed for?
It is listed for the upstream, downstream, upstream left and upstream right positions. The listing is one sensor.
