Autopart International 1900-522173 Air Fuel Ratio Sensor

The Autopart International 1900-522173 is a direct-fit air fuel ratio sensor designed to monitor and optimize your engine's air-to-fuel mixture. This sensor provides critical feedback to the engine control module (ECM), enabling precise fuel delivery adjustments for improved performance, fuel efficiency, and reduced emissions.

Key Features:

• Direct replacement for worn or failed original equipment sensors
• Monitors exhaust gas oxygen content to maintain optimal combustion
• Helps prevent check engine light codes related to fuel mixture
• Engineered to meet or exceed OEM specifications
• Includes vehicle-specific wiring connector for straightforward installation

Air fuel ratio sensors are wider-range versions of oxygen sensors that provide more precise readings across a broader spectrum of air-fuel mixtures. When functioning properly, this sensor helps maximize fuel economy while minimizing harmful exhaust emissions. A failing air fuel ratio sensor can cause rough idle, poor acceleration, decreased fuel economy, and illuminate the check engine light.
