Hella 009403461 Turbocharger Boost Pressure Sensor 3-Pin with Seal Ring

The Hella 009403461 is a direct-fit intake manifold pressure sensor (MAP sensor / turbocharger boost sensor) engineered to OEM standards. Intake manifold and boost pressure sensors are located in the vehicle's intake tract and continuously measure air pressure, delivering precise data to the engine control unit (ECU) so it can accurately calculate air mass and optimize the fuel-air mixture for efficient combustion.

Hella brings decades of original equipment manufacturing expertise to this sensor. Built to the same specifications as the factory part, it provides seamless integration with modern engine management systems and reliable signal output under demanding conditions.

Key Features:

• 3-pin connector for direct plug-and-play installation — no wiring modifications required
• Bolted mounting design for a secure, vibration-resistant fit
• Includes seal ring — all necessary hardware included for a complete installation
• Measures intake manifold absolute pressure and relays data to the ECU for precise air-fuel ratio control
• Engineered to OEM fit, form, and function standards
• Heat-resistant and vibration-tolerant construction for long service life
• Manufactured by Hella — a globally recognized OEM supplier of automotive sensors and electronics

A faulty boost or MAP sensor can cause poor fuel economy, rough idling, hesitation under acceleration, increased emissions, and a check engine light. Replacing it with a quality Hella unit restores accurate pressure monitoring and proper engine management operation. Part number: 009403461.
