Autopart International 1904-300689 Manifold Absolute Pressure MAP Sensor

The Autopart International 1904-300689 is a direct-replacement Manifold Absolute Pressure (MAP) sensor designed to restore proper engine management system functionality. This sensor monitors intake manifold vacuum and pressure, providing critical data to the engine control unit (ECU) for optimal fuel delivery and ignition timing.

Key Features:

• Direct replacement for factory MAP sensor
• Monitors manifold absolute pressure for precise engine management
• Provides variable electrical output signal based on intake vacuum
• Enables ECU to calculate air density and mass airflow rates
• Essential for maintaining proper air-fuel ratio and engine performance
• Quality-tested to meet OE specifications

A failing MAP sensor can cause poor fuel economy, rough idle, hesitation, and check engine light illumination. This replacement sensor restores accurate pressure readings to ensure your engine runs efficiently with proper stoichiometric fuel mixture. Designed for reliable performance and easy installation.
