The NTK/NGK direct-fit oxygen sensor for Toyota 4Runner (1990–1991) supplies continuous feedback to the ECU for air–fuel ratio control and emissions monitoring. NTK’s background as a ceramic specialist informs their production process from raw materials through final assembly. The sensor uses an advanced ceramic element with a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to protect against element poisoning.
