Autopart International 1904-310878 Manifold Absolute Pressure MAP Sensor

The Autopart International 1904-310878 is a direct-fit replacement Manifold Absolute Pressure (MAP) sensor designed to restore proper engine management performance. This sensor monitors intake manifold pressure and delivers real-time data to the engine control unit (ECU), enabling precise fuel delivery and ignition timing calculations.

The MAP sensor is a critical component in fuel-injected engines. By continuously measuring manifold vacuum and pressure, it allows the ECU to determine air density and air mass flow rate, ensuring the correct air-fuel mixture for efficient combustion. A faulty MAP sensor can result in poor fuel economy, rough idle, loss of power, or a check engine light.

Key Features:

• Direct OE replacement — engineered to match original fit, form, and function
• Provides accurate manifold pressure readings to the ECU for optimal fuel metering
• Supports proper ignition timing control for improved engine efficiency
• Compatible with OBD II diagnostic systems for EGR valve functionality testing
• Manufactured to meet or exceed original equipment specifications

The Autopart International 1904-310878 MAP sensor is a reliable aftermarket solution for restoring accurate engine management. It installs in place of the original sensor with no modifications required.
