Autopart International 1904-486829 Manifold Absolute Pressure MAP Sensor

The Autopart International 1904-486829 is a Manifold Absolute Pressure (MAP) Sensor designed to provide accurate pressure readings for proper engine management. This sensor monitors the pressure inside the intake manifold and transmits real-time data to the vehicle's Engine Control Unit (ECU) for optimal fuel delivery and ignition timing.

Key Features:

• Monitors intake manifold pressure for precise engine control
• Sends critical data to the ECU for air density and mass flow calculations
• Helps optimize fuel metering for efficient combustion
• Supports proper ignition timing adjustments
• Essential component for modern fuel-injected engines
• May be used in OBD-II diagnostics for EGR valve testing

The MAP sensor plays a vital role in engine performance by enabling the ECU to calculate air density and determine the correct air-to-fuel ratio. A properly functioning MAP sensor ensures smooth engine operation, optimal fuel efficiency, and reduced emissions.
