Autopart International 1904-559536 Manifold Absolute Pressure MAP Sensor

The Autopart International 1904-559536 is a Manifold Absolute Pressure (MAP) sensor designed to monitor engine intake manifold pressure and send critical data to the engine control module (ECM). This sensor plays a vital role in determining air density and calculating the proper air-fuel mixture for optimal engine performance and fuel efficiency.

Key Features:

• Direct replacement for worn or failed factory MAP sensor
• Monitors intake manifold vacuum and barometric pressure
• Helps optimize fuel delivery and ignition timing
• Ensures proper engine performance and emissions control
• Quality-tested to meet OE specifications

A failing MAP sensor can cause poor acceleration, rough idling, decreased fuel economy, and illuminated check engine lights. This replacement sensor restores proper engine management system function and helps maintain reliable vehicle operation.
