Autopart International 1904-590240 Manifold Absolute Pressure MAP Sensor

The Autopart International 1904-590240 is a Manifold Absolute Pressure (MAP) sensor designed to monitor engine intake manifold pressure and provide critical data to the vehicle's engine control module (ECM). This sensor plays a vital role in fuel delivery calculations, ignition timing, and emissions control by measuring the difference between manifold vacuum and atmospheric pressure.

Key Features:

• Direct replacement for original equipment MAP sensor
• Provides accurate pressure readings for optimal engine performance
• Helps maintain proper air-fuel mixture and fuel economy
• Engineered to meet OE specifications for fit and function
• Durable construction for reliable operation in harsh underhood conditions

A faulty MAP sensor can cause poor engine performance, rough idle, decreased fuel economy, and check engine light illumination. This replacement sensor restores proper engine management system operation and helps maintain optimal vehicle performance.
