Product Details

Mando New Original Equipment parts are built to match original equipment requirements for Hyundai and Kia platforms. This oxygen sensor is used in the exhaust stream to report oxygen content to the engine management system, helping the vehicle adjust fueling as conditions change. The 18A1455 is a fitment-specific replacement for upstream and downstream locations across select Hyundai Santa Fe, XG350, and Kia Sorento, Sedona, Amanti, Optima, and Rondo applications. This part cross-references Hyundai 39210-39800 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor faults
• Rough or erratic engine idle
• Poor fuel economy from incorrect air-fuel readings
• Hard starting caused by inaccurate sensor input
• Emission control performance issues tied to sensor wear

Installation Notes

Verify the sensor position before ordering, since fitment includes upstream, downstream, and downstream left locations. Match the vehicle year, make, model, and exhaust position exactly to the listed application. Inspect the connector and exhaust threads during replacement, and confirm the fault code has been diagnosed before installing a new sensor.
