Autopart International 1900-522187 Air Fuel Ratio Sensor

The Autopart International 1900-522187 is a direct-fit replacement air fuel ratio sensor designed to monitor the oxygen content in your vehicle's exhaust system. This sensor provides critical data to the engine control module (ECM) to optimize the air-fuel mixture for maximum efficiency, performance, and emissions control.

Key Features:

• Direct replacement for factory air fuel ratio sensor
• Monitors exhaust oxygen content for precise fuel mixture adjustment
• Helps maintain optimal engine performance and fuel economy
• Assists in reducing harmful emissions and maintaining emissions compliance
• Vehicle-specific design ensures proper fit and function
• Includes necessary connectors for straightforward installation

Air fuel ratio sensors are more advanced than traditional oxygen sensors, providing a wider range of measurement for more precise fuel control. A failing sensor can trigger check engine lights, reduce fuel economy, cause rough idle, and lead to increased emissions. This replacement sensor restores proper engine management system function and helps your vehicle run efficiently.
