Autopart International 1802-306374 Manifold Absolute Pressure MAP Sensor

The Autopart International 1802-306374 is a Manifold Absolute Pressure (MAP) sensor designed as a direct replacement for fuel-injected engines. This sensor plays a critical role in the engine management system by monitoring air pressure within the intake manifold and transmitting real-time data to the vehicle's electronic control unit (ECU).

Key Features:

• Measures intake manifold pressure to optimize fuel metering and ignition timing
• Provides instantaneous pressure data to the ECU for accurate air density calculations
• Designed to match original equipment specifications for reliable performance
• Durable construction engineered to withstand heat and engine bay conditions
• Direct replacement sensor for straightforward installation

The ECU uses the MAP sensor data to determine air mass flow rate and calculate the precise fuel-to-air ratio needed for optimal combustion efficiency. This sensor may also be utilized in OBD-II diagnostic systems to test EGR valve functionality. When the original MAP sensor fails due to heat exposure or internal component damage, this replacement sensor helps restore proper engine performance and fuel economy.
