Walker Products 350-34014 oxygen sensor for the 2002-2005 Hyundai Sonata V6 2.7L and other vehicles measures the oxygen content of the exhaust gas. This Walker Products oxygen sensor is a narrow-band, 4-wire unit made for its specific application and fitment position, and it gives the ECU the diagnostic feedback it needs.
- Determines the oxygen content of the exhaust gas to monitor the air fuel ratio for combustion efficiency
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust
- Monitors exhaust gases and reduces pollutants for a cleaner environment
- Electrodes are made of a gas-permeable platinum layer
- Oxygen readings help fine-tune the air-fuel mixture to support fuel economy
Quick facts
- Part: Walker Products 350-34014 oxygen sensor
- Fits: the 2002-2005 Hyundai Sonata V6 2.7L and other vehicles
- Position: upstream left, upstream right, downstream left, upstream rear, upstream front, downstream front, downstream rear
- Condition: New
A failing sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. Because other problems produce those signs too, look for the actual cause first. With the engine off and cool, inspect the sensor, wiring harness and connector for physical damage.
Fits
This oxygen sensor replacement suits the 2002-2005 Hyundai Sonata V6 2.7L, and it is also an oxygen sensor for the 2003-2009 Hyundai Santa Fe V6 2.7L and the 2005-2009 Hyundai Tucson V6 2.7L; each takes one.

Frequently Asked Questions
Is this the right O2 sensor for a 2002-2005 Hyundai Sonata V6 2.7L?
Yes, Walker Products 350-34014 is listed for the 2002-2005 Hyundai Sonata V6 2.7L, which takes one. For other models, open the "Vehicles it fits" section and check your engine.
What thread does the Walker Products 350-34014 oxygen sensor have?
Walker Products 350-34014 has an M18 - 1.5 thread. It is a narrow-band sensor with 4 wires.
Which positions is this oxygen sensor sold for?
For this part number the catalog lists upstream left, upstream right, downstream left, upstream front, upstream rear, downstream front and downstream rear.
What can a failing oxygen sensor do to the engine?
It can show up as rough running, higher fuel consumption or a malfunction indicator light. Newer vehicles store fault codes in the ECU, which a shop can read.
What does the coating on this oxygen sensor protect?
It keeps combustion residue and particulates in the exhaust gas from contaminating or eroding the electrode surfaces. The electrodes themselves carry a gas-permeable platinum layer.
