Walker Products 250-24966 oxygen sensor for the 2009 Seat Ibiza 4-cylinder 1.6L, the 2009-2015 Ibiza 4-cylinder 2.0L, the 2011-2012 Ibiza 4-cylinder 1.4L, the 2014-2016 Ibiza 4-cylinder 1.6L, the 2015 Ibiza 4-cylinder 1.4L, the 2017 Ibiza and other vehicles measures the oxygen content of the exhaust gas. This downstream sensor is made for its specific application and position, and it gives the ECU the diagnostic feedback it needs.
- Measures exhaust oxygen content to monitor the air-fuel ratio for combustion efficiency
- Narrow-band sensor with four wires for the downstream position
- Coating protects the electrode surfaces from combustion residue and particulates in the exhaust gases
- Electrodes made of a gas-permeable platinum layer
- Monitors exhaust gases as part of reducing pollutants
Quick facts
- Part: Walker Products 250-24966 oxygen sensor
- Fits: the 2009 Seat Ibiza 4-cylinder 1.6L, the 2009-2015 Ibiza 4-cylinder 2.0L, the 2011-2012 Ibiza 4-cylinder 1.4L, the 2014-2016 Ibiza 4-cylinder 1.6L, the 2015 Ibiza 4-cylinder 1.4L, the 2017 Ibiza and other vehicles
- Position: Downstream
- Condition: New
Rough running, higher fuel consumption or a lit malfunction indicator light can mean the sensor is failing, though a damaged wiring harness or connector can be behind the same signs, so look both over for physical damage before you replace the sensor.
Fits
The 2015-2017 Volkswagen Polo 4-cylinder 1.6L, the 2017 Polo 4-cylinder 1.8L and the 2011 Seat Exeo 4-cylinder 2.0L fit this sensor too, and so do many other vehicles. Open the "Vehicles it fits" section and check your own model and engine there.

Frequently Asked Questions
Is this Polo oxygen sensor right for the 2015-2017 Volkswagen Polo 4-cylinder 1.6L?
Yes. Walker Products 250-24966 is a downstream sensor listed for the 2015-2017 Volkswagen Polo 4-cylinder 1.6L, and the same listing covers the 2017 Polo 4-cylinder 1.8L.
Does this Seat Ibiza oxygen sensor fit the 2014-2016 Ibiza 4-cylinder 1.6L?
Yes. Walker Products 250-24966 is listed for the 2014-2016 Seat Ibiza 4-cylinder 1.6L as a downstream sensor.
Is this downstream oxygen sensor narrow-band?
Yes. This sensor is a narrow-band design with four wires, made for the downstream position.
How do I know if this oxygen sensor is going bad?
A failing sensor can show up as rough running, higher fuel consumption or a lit malfunction indicator light. A shop can test it and the wiring to find the cause.
Are the electrodes on this oxygen sensor protected from exhaust residue?
Yes. The electrodes are made of a gas-permeable platinum layer, and a coating protects their surfaces from contamination and erosion by combustion residue and particulates.
