An O2 sensor detects oxygen content in exhaust gases, feeding back to the ECU to adjust the air-fuel ratio to 14.7:1 for optimal fuel economy and emissions. Front O2 sensors control closed-loop air-fuel ratio before the catalytic converter, while rear ones monitor converter efficiency. Our O2 sensors for Japanese, American, German, French, and Chinese vehicles ensure precise oxygen detection. Contact us for specifications and pricing.
