Facet 10.3034 Manifold Absolute Pressure Sensor MAP

The Facet 10.3034 is a manifold absolute pressure (MAP) sensor designed to measure intake manifold pressure and provide critical engine load data to the engine control unit. This sensor is commonly used in speed-density engine management systems that do not utilize an air flow or mass sensor.

Key Technical Specifications:

• Pressure range: 0.1 to 2.5 bar
• Number of ports: 3-pin electrical connector
• Sensor type: Absolute pressure sensor
• Function: Measures intake manifold pressure for engine load calculation
• Also functions as boost pressure sensor in turbocharged applications

OEM Cross-Reference Numbers: Compatible with OEM part numbers 9639469280, 31216185, 9639027480, 1920CZ, and 18590-69K00-000. Commonly used in Citroën, Fiat, and Ford applications.

MAP sensors are essential for proper engine performance, fuel economy, and emissions control. A faulty MAP sensor can cause rough idle, surging, loss of power, poor fuel economy, detonation, or spark plug fouling due to incorrect air-fuel mixture calculations.
