Walker Products 250-25049 oxygen sensor for the 2014-2016 Hyundai Elantra 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas. This Walker Products oxygen sensor is a wide-band unit that helps the ECU track the air-fuel ratio and combustion efficiency.
A failing sensor can show up as rough running, higher fuel consumption, more exhaust emissions or a lit malfunction indicator light. A damaged wiring harness or connector can be behind the same signs, so look both over for physical damage and find the cause before buying a sensor. Newer vehicles store fault codes in the ECU, and some point to the affected sensor.
The vehicles it fits include the 2014-2016 Hyundai Elantra 4-cylinder 2.0L and the 2015-2018 Hyundai Tucson 4-cylinder 2.0L; it also works as a Kia Sorento oxygen sensor for the 2019-2020 V6 3.3L. Each takes one sensor, and this listing is one. If your car is not named here, look it up on the Buyer's Guide tab.
