Holstein 2MAP4002 Manifold Absolute Pressure (MAP) Sensor for GM Vehicles

The Holstein 2MAP4002 is a direct-replacement Manifold Absolute Pressure (MAP) sensor designed for GM vehicles. This sensor monitors intake manifold vacuum and atmospheric pressure, providing critical data to the engine control module (ECM) for proper fuel delivery and ignition timing calculations.

Key Features:

• Direct OEM replacement for GM applications
• Measures manifold absolute pressure for accurate engine management
• Helps optimize fuel efficiency and engine performance
• Quality-tested to meet or exceed OE specifications
• Includes electrical connector for plug-and-play installation

The MAP sensor is essential for proper engine operation, particularly during acceleration and varying load conditions. A faulty MAP sensor can cause rough idle, poor fuel economy, lack of power, or trigger check engine lights. This Holstein replacement sensor restores proper engine control system function.
