The NGK direct‑fit oxygen sensor for Nissan Pathfinder (2003–2004) supplies continuous closed‑loop feedback to the ECU to control the air‑fuel ratio and inform OBDII systems about fuel delivery or catalytic converter efficiency. NTK/NGK ceramic development and manufacturing control the element from raw material to finished product, and a 3‑stage contaminant‑resistant plasma jet with deposit‑trap overcoat helps protect the sensor element.
