Autopart International 1904-486809 Manifold Absolute Pressure MAP Sensor

The Autopart International 1904-486809 is a direct replacement Manifold Absolute Pressure (MAP) sensor designed to monitor intake manifold pressure and deliver critical data to your vehicle's engine control unit (ECU). This sensor plays a vital role in engine management by measuring the absolute pressure inside the intake manifold, allowing the ECU to calculate air density and determine the proper air-fuel mixture for optimal combustion.

Key Features:

• Direct replacement MAP sensor for reliable engine performance
• Monitors manifold pressure and transmits data to the ECU for fuel delivery calculations
• Helps maintain proper air-fuel ratio based on engine load conditions
• Engineered to meet or exceed OEM specifications
• Essential component for smooth idle, acceleration, and fuel efficiency

A properly functioning MAP sensor is critical for maintaining optimal engine performance, fuel economy, and emissions control. Symptoms of a failing MAP sensor include rough idle, poor acceleration, decreased fuel efficiency, and illuminated check engine light. This Autopart International replacement sensor restores proper engine management system operation.
