    Walker Products 250-24977 oxygen sensor for the 2020 Hyundai Elantra 4-cylinder 2.0L measures the oxygen content of the exhaust gas. It is made for its specific application and mounting position and sends the ECU the diagnostic feedback it requires.

    • Narrow-band design with four wires
    • Coating protects the electrode surfaces from contamination and erosion by combustion residue and particulates
    • Electrodes made of a gas-permeable platinum layer
    • Monitors exhaust gases and helps reduce pollutants
    • Measures oxygen content to monitor the air-fuel ratio for combustion efficiency

    Quick facts

    • Part: Walker Products 250-24977 oxygen sensor
    • Fits: 2020 Hyundai Elantra 4-cylinder 2.0L
    • Position: Downstream
    • Condition: New

    A failing sensor can make the engine run poorly, raise fuel consumption and exhaust emissions, or turn on the malfunction indicator light. A vacuum leak can also leave an engine running poorly, so these signs alone do not prove the sensor is the problem. Newer vehicles may store fault codes in the ECU that relate to the sensor.

    Fits

    This downstream sensor is a direct-fit replacement for the 2020 Hyundai Elantra 4-cylinder 2.0L, which takes one.

    Frequently Asked Questions

    Is this Elantra oxygen sensor right for the 2020 Hyundai Elantra 4-cylinder 2.0L?

    Yes. Walker Products 250-24977 is a downstream sensor listed for the 2020 Hyundai Elantra 4-cylinder 2.0L, and that car takes one.

    Is this Walker Products oxygen sensor narrow-band or wideband?

    It is narrow-band, with four wires and an M18 - 1.5 thread. Walker Products 250-24977 is a downstream sensor.

    What does the coating on this oxygen sensor do?

    The coating prevents contamination and erosion of the electrode surfaces by combustion residue and particulates in the exhaust gases. The electrodes are made of a gas-permeable platinum layer.

    What should I look at if a downstream oxygen sensor seems to be failing?

    Look over the sensor, wiring harness and connector for physical damage, with the engine off and cool. Damage there can also shorten the sensor's operating life.

    Does this sensor send the diagnostic feedback the ECU needs?

    Yes. It is made for its specific application and mounting position and gives the diagnostic feedback the ECU requires. Newer vehicles may store fault codes related to the sensor.
