VEMO V51-72-0091 Manifold Absolute Pressure MAP Sensor

The VEMO V51-72-0091 is a high-quality Manifold Absolute Pressure (MAP) sensor designed to provide precise intake manifold pressure readings to your vehicle's engine control unit. This aftermarket replacement sensor plays a critical role in engine management by monitoring vacuum and pressure conditions within the intake manifold, enabling optimal fuel delivery and ignition timing for improved performance and efficiency.

Key Features:

• 3-pole electrical connector for reliable signal transmission
• Lightweight construction at just 0.037 lbs (17 grams)
• Compact dimensions: 4.94cm depth x 6.7cm height x 3.37cm width
• Direct replacement for OEM MAP sensors on select GM vehicles
• Precision pressure sensing element for accurate engine load measurement

How It Works:

The MAP sensor measures the absolute pressure difference between the intake manifold and ambient atmospheric pressure, converting this data into an electrical signal for the ECU. The engine computer uses this information along with data from other sensors to calculate air density and mass airflow, determining the precise fuel metering and spark advance needed for optimal combustion. This sensor is essential for maintaining proper air/fuel ratios, reducing emissions, and maximizing fuel economy across all engine operating conditions.

Applications:

This VEMO MAP sensor is commonly found on various General Motors vehicles including Chevrolet, Buick, GMC, and Hummer models from the early 2000s. It's suitable for both naturally aspirated and some forced induction applications where manifold pressure monitoring is required for engine management.

VEMO is a trusted manufacturer of automotive sensors, switches, and engine management components, known for producing reliable aftermarket solutions that meet or exceed OEM specifications.
