The NGK wideband 4‑wire air‑fuel sensor for Volvo S70 (1999–2000) delivers a linear AFR signal so the ECU can make precise air–fuel adjustments for optimal combustion and emissions. NTK’s ceramics expertise and ongoing design improvements support durability and resistance to failure. The sensor uses an advanced ceramic element protected by a 3-stage contaminant‑resistant plasma jet and deposit‑trap overcoat to guard against element poisoning.
