第九代索纳塔氧传感器 39210-2E401 通用原厂标准 性能稳定

When your ninth-generation Hyundai Sonata experiences unstable idle, noticeably higher fuel consumption, or the engine warning light is on, it usually indicates aging oxygen sensor failure and inability to accurately monitor oxygen content in exhaust. This sensor, when working properly, feeds the ECU with the air-fuel ratio signal to ensure complete combustion and regulated emissions. This product OEM number is 39210-2E401, compatible with all Hyundai 9th-gen Sonata models. During installation, be sure to use a dedicated socket to avoid thread damage, and ensure the sensor wiring does not contact the exhaust pipe to prevent high-temperature melting.
