Autopart International 1904-604123 Manifold Absolute Pressure MAP Sensor

The Autopart International 1904-604123 is a direct replacement Manifold Absolute Pressure (MAP) sensor designed to restore proper engine management system function. This sensor monitors intake manifold pressure and sends critical data to the engine control unit (ECU) to optimize fuel delivery, ignition timing, and overall engine performance.

Key Features:

• Monitors manifold vacuum and atmospheric pressure for accurate air density calculation
• Provides real-time pressure data to the ECU for optimal fuel-air mixture control
• Direct-fit replacement design for straightforward installation
• Durable construction built to OE specifications for reliable performance
• Helps maintain proper engine idle, acceleration, and fuel economy

A failing MAP sensor can cause poor fuel economy, rough idle, hesitation during acceleration, and illuminated check engine lights. This replacement sensor helps restore proper engine management system operation and ensures accurate air-fuel ratio calculations for optimal combustion efficiency.
