Autopart International 1904-486817 Manifold Absolute Pressure MAP Sensor

The Autopart International 1904-486817 is a 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 measures the absolute pressure inside the intake manifold and converts it into an electrical signal, allowing the ECU to calculate air density and determine the optimal air-fuel mixture for efficient combustion.

Key Features:

• Monitors intake manifold vacuum and pressure for precise engine management
• Provides real-time data to the ECU for fuel injection and ignition timing calculations
• Direct replacement sensor designed to meet OE specifications
• Helps optimize engine performance, fuel economy, and emissions control
• Critical component for modern electronic fuel injection systems

A functioning MAP sensor is essential for proper engine operation. Symptoms of a failing MAP sensor include rough idle, poor acceleration, decreased fuel economy, and illuminated check engine lights. This Autopart International replacement sensor restores accurate manifold pressure readings to ensure your engine runs smoothly and efficiently.
