Autopart International 1900-522166 Air Fuel Ratio Sensor

The Autopart International 1900-522166 Air Fuel Ratio Sensor is a direct-fit replacement sensor designed to monitor the oxygen content in your vehicle's exhaust system. This sensor plays a critical role in engine management by providing real-time feedback to the engine control module (ECM) about the air-to-fuel mixture, enabling optimal combustion efficiency and reduced emissions.

Key Features:

• Measures air-to-fuel ratio information under a wide range of driving conditions
• Sends precise data to the ECM for continuous mixture adjustments
• Helps improve fuel economy and reduce harmful emissions
• Direct-fit replacement sensor for simplified installation
• Manufactured to meet or exceed OE specifications

Air/fuel ratio sensors, also known as wide-band oxygen sensors, provide a broader response range than traditional oxygen sensors, allowing for much finer control of air/fuel mixtures across various operating conditions. This advanced technology helps your engine burn fuel more efficiently while maintaining compliance with modern emissions standards.
