Walker Products 350-34509 oxygen sensor for the 2006-2016 Seat Ibiza 4-cylinder 1.6L, the 2009-2015 Ibiza 4-cylinder 2.0L, the 2011-2012 Ibiza 4-cylinder 1.4L, the 2015 Ibiza 4-cylinder 1.4L, the 2017 Ibiza and other vehicles measures the oxygen content of the exhaust gas to gauge combustion efficiency. Each part number is made for its specific application and fitment position, and gives the ECU the diagnostic feedback it expects.
- Electrodes with a gas-permeable platinum layer
- Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates in the exhaust gases
- Oxygen sensor monitors exhaust gases to help reduce pollutants
- Measures oxygen levels to help fine-tune the air-fuel ratio and support fuel economy
- Narrow-band design with 4 wires
Quick facts
- Part: Walker Products 350-34509 oxygen sensor
- Fits: the 2006-2016 Seat Ibiza 4-cylinder 1.6L, the 2009-2015 Ibiza 4-cylinder 2.0L, the 2011-2012 Ibiza 4-cylinder 1.4L, the 2015 Ibiza 4-cylinder 1.4L, the 2017 Ibiza and other vehicles
- Position: Center, upstream, downstream left
- Condition: New
A failing oxygen sensor might show up as the engine running poorly, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. Those signs alone do not prove the sensor is the problem, since an exhaust leak near it is another common cause. This listing is one sensor, and the quantity per vehicle is one.
Fits
This narrow-band oxygen sensor is also a direct-fit replacement for the 2016-2017 Volkswagen Polo and the 2011-2012 Seat Leon 4-cylinder 1.4L. Don't see your car here? Look it up in the "Vehicles it fits" section.
