The NGK direct-fit oxygen sensor for Toyota Sienna (2004–2010) restores OE-style oxygen feedback to the vehicle’s on-board diagnostic system, helping the ECU maintain proper air–fuel ratio, optimize fuel economy and reduce harmful emissions. NTK applies ceramics expertise with a 3-stage contaminant-resistant ceramic element and deposit-trap overcoat to resist element poisoning and improve sensor longevity and reliability.
