A car oxygen sensor (O2 sensor) detects oxygen content in exhaust gases, feeding back to the ECU to adjust the air-fuel ratio to the theoretical 14.7:1. Front O2 sensors (before the catalytic converter) control closed-loop air-fuel ratio, while rear ones (after) monitor converter efficiency. Our O2 sensors for Japanese, American, German, French, and Chinese vehicles ensure emission compliance and fuel economy. Contact us for specifications.
