The NGK 5‑wire wideband air‑fuel sensor for Hyundai Sonata (2009–2010) is a direct‑fit oxygen sensor that supplies a linear A/F signal, enabling the ECU to make continuous adjustments for better combustion, fuel economy and emissions control. The sensor uses advanced ceramic construction with a 3‑stage contaminant‑resistant plasma jet and deposit‑trap overcoat to guard the element against poisoning and improve reliability.
