Bosch 0261230439 Manifold Absolute Pressure MAP Sensor

The Bosch 0261230439 Manifold Absolute Pressure (MAP) Sensor is a precision-engineered sensor designed to measure intake manifold pressure and provide critical data to the engine control unit (ECU) for optimal engine performance and fuel efficiency. This sensor plays a vital role in maintaining the ideal air-fuel mixture for combustion, ensuring smooth engine operation and responsive throttle control.

Key Features:

• Pressure range: 0.5 to 4.0 bar (28.9 to 400.0 kPa) for accurate boost pressure monitoring
• 3-pin electrical connector with male rectangular blade terminals
• Durable construction engineered to withstand extreme temperatures and harsh engine bay conditions
• Direct OEM replacement for Mercedes-Benz part numbers A0071530028, A0101537228, and A0061531628
• Also replaces Bosch part numbers 0261230195, 0261230196, and 0261230153
• Plug-and-play installation with no modifications required

This MAP sensor is essential for proper engine management system operation. It measures manifold vacuum and boost pressure, allowing the ECU to calculate engine load and adjust fuel delivery and ignition timing accordingly. Common symptoms of a failing MAP sensor include rough idling, poor fuel economy, decreased engine performance, hesitation during acceleration, and illumination of the check engine light. Replacing a faulty MAP sensor can restore smooth operation, improve fuel efficiency, and eliminate diagnostic trouble codes.
