Facet 10.3378 Manifold Absolute Pressure Sensor

The Facet 10.3378 is a Manifold Absolute Pressure (MAP) sensor designed to monitor intake manifold pressure and provide critical data to the engine control unit (ECU). This sensor measures the absolute pressure inside the intake manifold to help determine engine load, allowing the ECU to optimize fuel injection timing and air-fuel ratio for improved performance and efficiency.

Key Features:

• Direct replacement MAP sensor for various automotive applications
• Monitors intake manifold vacuum and pressure changes
• Provides accurate pressure readings to the engine management system
• Helps optimize fuel economy and reduce emissions
• Durable construction designed for long service life
• Engineered to OE specifications for reliable performance

The MAP sensor plays a vital role in modern engine management systems by continuously measuring manifold pressure. When the sensor fails, symptoms can include poor fuel economy, rough idle, hesitation during acceleration, and illuminated check engine lights. This Facet replacement sensor restores proper engine operation and diagnostic functionality.
