Walker Products 250-24864 oxygen sensor for the 2010-2013 Hyundai Tucson 4-cylinder 2.4L, the 2011-2013 Tucson 4-cylinder 2.0L and other vehicles feeds exhaust-gas oxygen readings to the engine computer. This Walker Products oxygen sensor is a 4-W direct-fit narrow-band unit made for its specific application and the downstream position.
- Determines the oxygen content of the exhaust gas to monitor the air-fuel ratio for combustion efficiency
- Electrodes made of a gas-permeable platinum layer
- Coating guards the electrode surfaces against contamination and erosion from combustion residue and particulates
- Monitors exhaust gases to help reduce pollutants
- Oxygen readings help fine-tune the air-fuel mixture, which can improve fuel economy
Quick facts
- Part: Walker Products 250-24864 oxygen sensor
- Fits: 2010-2013 Hyundai Tucson 4-cylinder 2.4L, the 2011-2013 Tucson 4-cylinder 2.0L and other vehicles
- Position: Downstream
- Condition: New
A failing sensor can show up as rough running, higher fuel use, higher emissions or a lit MIL, but other faults cause the same signs. Before you replace it, look over the sensor, its wiring harness and the connector for physical damage with the engine off and cool.
Fits
This downstream sensor is also a Kia Optima oxygen sensor for the 2009-2010 model with the 4-cylinder 2.4L, and it fits the 2011-2013 Kia Sportage 4-cylinder 2.4L and the 2011-2016 Sportage 4-cylinder 2.0L.

Frequently Asked Questions
Does this Hyundai Tucson oxygen sensor fit a 2010-2013 model with the 4-cylinder 2.4L?
Yes. Walker Products 250-24864 fits the 2010-2013 Hyundai Tucson 4-cylinder 2.4L and the 2011-2013 Tucson 4-cylinder 2.0L as the downstream sensor. Look up your own car in the "Vehicles it fits" section.
Does this Kia Sportage oxygen sensor fit the 2011-2016 model with the 4-cylinder 2.0L?
Yes. Walker Products 250-24864 fits the 2011-2016 Kia Sportage 4-cylinder 2.0L and the 2011-2013 Sportage 4-cylinder 2.4L, one sensor per vehicle.
What is the platinum layer on this oxygen sensor for?
The electrodes are made of a gas-permeable platinum layer. A coating keeps combustion residue and particulates in the exhaust from contaminating or eroding the electrode surfaces.
What signs can point to a worn downstream oxygen sensor?
The engine can run poorly, fuel use or emissions can rise, or the MIL can light. A shop can scan for stored fault codes to help narrow down the cause.
Is the Walker Products 250-24864 a narrow-band or wideband oxygen sensor?
It is a narrow-band sensor. Walker Products 250-24864 is a 4-W direct-fit unit built for the downstream position.
