Bosch 0261230280 Pressure Sensor

Overview

The Bosch 0261230280 Pressure Sensor is a high‑precision intake manifold pressure (MAP) sensor, also known as a boost pressure sensor. It measures the absolute air pressure within an engine’s intake manifold, providing critical data for the vehicle’s engine control unit (ECU). This information allows the ECU to adjust fuel injection, ignition timing, and turbocharger boost levels for optimal performance, efficiency, and emissions.

Key Features

• Wide Operating Temperature Range: From -40 °C to +125 °C, ensuring reliable operation in extreme climates.
• High Accuracy: Provides precise pressure readings with minimal drift over time.
• Compact Design: Small footprint fits easily into modern engine bays without requiring additional space.
• Robust Construction: Durable housing resists vibration, corrosion, and high temperatures typical of turbocharged engines.
• Standardized Interface: 4‑pin connector compatible with most OEM ECU wiring harnesses.
• Altitude Compensation: Automatically adjusts for changes in atmospheric pressure, maintaining accurate readings at varying elevations.

Applications

This sensor is widely used across a range of vehicles, particularly those equipped with turbocharged or supercharged engines. Common applications include:

• Ford: Fiesta Mk6, Focus, Mondeo, Kuga, C‑Max, B‑MAX, S‑MAX, Transit Connect, and Mustang EcoBoost models.
• Volvo: V60, V70, S60, XC60, and other turbocharged platforms.
• Other Manufacturers: Saab 9‑3, Vauxhall Astra Zafira, Fiat, Mercedes‑Benz, Iveco, Peugeot, Opel, and more.

Installation Notes

• The sensor is typically mounted directly to the intake manifold or turbocharger inlet pipe. Ensure a clean, flat surface for optimal sealing.
• Use the supplied gasket or O‑ring to create a leak‑free seal.
• Connect the 4‑pin cable to the ECU’s MAP input port; verify polarity and secure all connections.
• After installation, perform an ECU reset or relearn procedure as recommended by the vehicle manufacturer to calibrate the new sensor data.

Performance Benefits

• Improved Fuel Efficiency: Accurate pressure readings enable precise fuel metering, reducing waste.
• Enhanced Power Delivery: The ECU can fine‑tune boost levels for smoother throttle response and higher peak power.
• Lower Emissions: Optimized combustion reduces harmful exhaust gases, aiding compliance with stringent regulations.
• Reliability: Durable construction minimizes failure rates in high‑stress environments.
