Autopart International 1904-302707 Manifold Absolute Pressure MAP Sensor

The Autopart International 1904-302707 is a direct replacement Manifold Absolute Pressure (MAP) sensor designed for modern engine management systems. This sensor plays a critical role in monitoring intake manifold pressure and transmitting that data to the engine control unit (ECU) for optimal fuel delivery and engine performance.

Key Features:

• Monitors manifold absolute pressure for accurate air density calculations
• Provides precise electrical signal output based on intake manifold vacuum
• Direct-fit replacement designed to meet or exceed OEM specifications
• Essential component for proper fuel-to-air ratio management
• Helps maintain optimal engine performance and fuel efficiency

The MAP sensor works by measuring the pressure differential in the intake manifold, allowing the ECU to calculate air mass flow rate and adjust fuel injection accordingly. When a MAP sensor fails, it can lead to poor engine performance, rough idling, decreased fuel economy, and illuminated check engine lights. This Autopart International replacement sensor restores proper engine management function and ensures reliable operation.
