The NGK wideband air–fuel sensor for Nissan Altima (2007–2011) gives a linear output so the ECU can accurately measure and adjust the air–fuel ratio for optimal combustion and lower emissions. NTK’s control of ceramic manufacturing and iterative design work improve resistance to failure; the sensor’s advanced ceramic element includes a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to guard against poisoning.
