Bosch 0281002976 Pressure Sensor

Bosch 0281002976 – The definitive Manifold Absolute Pressure (MAP) Sensor for modern internal combustion engines.

Core Functionality

The MAP sensor is the brain of an engine’s air‑fuel management system. It measures the pressure inside the intake manifold, providing real‑time data that allows the engine control unit (ECU) to calculate the exact amount of fuel required for optimal combustion. This precise measurement ensures:

• Efficient fuel consumption
• Reduced emissions
• Responsive throttle behavior
• Accurate idle stability

Design and Construction

The sensor is engineered with Bosch’s renowned high‑precision piezoelectric element, which converts pressure variations into a proportional electrical signal. Key design features include:

• Compact housing that fits seamlessly into standard intake manifolds.
• Robust sealing to protect against oil, coolant, and high temperatures.
• Integrated temperature compensation for consistent performance across a wide operating range.
• Standardized connector compatible with OEM wiring harnesses.

Compatibility Overview

The Bosch 0281002976 is engineered to match the exact specifications of many European and American vehicles. Its versatility stems from a universal signal output that aligns with the ISO 9141 and J1850 PWM protocols used by most modern ECUs.

Typical vehicle families include:

• Audi A3, A4, A5, A6, Q3, Q5, Q7, TT, TTS, and S3
• Volkswagen Golf, Passat, Tiguan, Touareg, Transporter, and Beetle
• Seat Leon, Ibiza, Toledo, and Arona
• Skoda Octavia, Superb, Yeti, Kodiaq, and Kamiq
• Porsche Macan, Cayenne, Panamera, and 911 (select models)
• Bentley Bentayga and Mulsanne (selected powertrains)
