Hella 009400291 Manifold Absolute Pressure MAP Sensor

The Hella 009400291 (6PP 009 400-291) is a precision-engineered manifold absolute pressure (MAP) sensor designed to monitor intake manifold pressure and boost pressure in modern fuel-injected engines. This critical engine management sensor provides real-time pressure data to the engine control unit (ECU), enabling optimal air-fuel mixture calculations, ignition timing adjustments, and turbocharger boost control.

Key Features:

• OE-quality manifold absolute pressure sensor for accurate engine management
• Dual-function design monitors both intake manifold pressure and turbocharger boost pressure
• 4-terminal electrical connector for reliable signal transmission
• Direct-fit replacement for multiple vehicle manufacturers including Alfa Romeo, Fiat, Ford, Honda, Iveco, Jeep, Lancia, Mazda, Nissan, Opel, Peugeot, and Citroën
• Backed by Hella's proven electronics expertise and rigorous quality standards

This sensor plays a vital role in engine performance by measuring absolute pressure in the intake manifold, allowing the ECU to calculate air density and determine the precise amount of fuel needed for efficient combustion. In turbocharged applications, it monitors boost pressure to prevent over-boost conditions and optimize power delivery. The Hella 009400291 meets or exceeds OEM specifications and is built to provide long-term reliability in demanding automotive environments.

Cross-Reference Part Numbers: Compatible with numerous OEM part numbers including Bosch 0 281 002 437, 0 281 006 028, Delphi PS10144, Facet 10.3082, and many manufacturer-specific numbers for Fiat (504088431, 504245257), Opel (1235029, 1235084), Peugeot (1636.39, 1636.61), Honda (37830-RBD-E01), and others.
