The NGK direct-fit oxygen sensor for Chevrolet Cavalier (2002–2005) provides constant closed-loop feedback to the engine control unit to help maintain the correct air–fuel ratio, maximize fuel economy and reduce emissions. Leveraging NTK ceramic sensor technology, it uses a 3-stage contaminant-resistant plasma-jet and deposit-trap overcoat to protect the ceramic element from poisoning and align with OE application expectations.
