Front Lambda O2 Oxygen Sensor for Hyundai i20 i30 i40 Elantra Sonata Tucson Kona
This Front Lambda O2 Oxygen Sensor is designed as a direct replacement for the front bank sensor on a range of Hyundai and Kia models, including Hyundai i20, i30, i40, Elantra, Sonata, Tucson and Kona. It monitors the exhaust gas oxygen level and supplies real-time data to the engine control unit to optimize the air–fuel ratio. With a heated design for faster warm-up, this sensor helps improve combustion efficiency, reduce emissions, and support stable idle and smooth acceleration across the engine’s operating range.
Main Description
Crafted for reliable performance, this O2 sensor uses magnetic induction and a heating element to ensure quick response in cold starts. It carries OEM reference 39350-2A640 and is compatible with multiple part numbers (39350-2A640, 393502A640, 39350 2A640, 9025050139). Originating from Mainland China, it’s a practical, high-compatibility solution for diesel CRDi engines found in Hyundai and Kia lineups. The sensor’s measurement range focuses on the Air Fuel Ratio (lambda) sensing, ensuring precise feedback to maintain optimal combustion and efficiency.
