The NGK direct-fit oxygen sensor for Lexus GS300 (1993–1994) supplies constant closed-loop feedback to the ECU to aid air-fuel ratio control, fuel economy and emissions monitoring. Its advanced ceramic element is protected by a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to guard against contamination and element poisoning, improving resistance to failure and helping ensure consistent OBDII diagnostic performance.
