The NGK direct-fit oxygen sensor for Mazda 626 (2000–2002) supplies continuous closed-loop data to the ECU to help maintain the correct air-fuel ratio and enable OBDII diagnostics. Leveraging NTK's OEM sensor development, the unit uses an advanced ceramic element with a three-stage contaminant-resistant plasma jet and deposit-trap overcoat to guard against element poisoning and boost resistance to failure for reliable operation in factory applications.
