Product overview
A set of two heated O2 oxygen sensors, one upstream and one downstream, for the Hyundai Elantra GT and Tucson 2.0L. Oxygen sensors measure the oxygen in the exhaust so the engine computer can keep the fuel mixture correct. A failing O2 sensor often causes a check engine light, poor fuel economy, rough idle or a failed emissions test.
