The NGK direct-fit oxygen sensor for Geo Prizm (1990–1992) supplies precise closed-loop feedback to the engine control unit to help control the air–fuel ratio, supporting engine performance, fuel economy and emissions control. The sensor employs an advanced ceramic element with a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to reduce poisoning, and is continually refined through OEM collaboration for reliable fit and service life.
