MAP Sensor for Mercedes-Benz - intake manifold absolute pressure (MAP) sensor Part numbers: 0051535028, 0061531328, A0041533228 Fits Mercedes-Benz models from 1998 to 2017. Please verify your vehicle model, year, and part numbers to ensure compatibility. If you are unsure, contact us for guidance to avoid unnecessary returns. What this sensor does - Measures the absolute pressure in the intake manifold downstream of the throttle plate. - Provides a signal that varies with engine speed and load to the engine control unit (ECU). - Supports accurate fuel metering and ignition timing for reliable engine performance. Why you need it - Restores accurate intake pressure readings, helping to maintain stable idle and smooth throttle response. - Improves fuel efficiency and engine performance when the original sensor has degraded. - Keeps engine management aligned with real operating conditions, reducing the risk of drivability issues. Key attributes - Function: direct measurement of manifold absolute pressure for correct ECU input. - Compatibility: OE-equivalent sensor designed to replace the original MAP sensor in Mercedes-Benz applications from 1998–2017. - Installation: direct-fit replacement that matches original equipment; non-destructive, fast, and straightforward. - Build: designed to maintain consistent performance with Mercedes-Benz engines over the intended model years. 2-3 use scenarios - Replacing a failing MAP sensor that causes rough idle, reduced power, or inconsistent fuel economy. - During routine OE replacement or preventive maintenance to preserve proper engine management and drivability. - After diagnosing intake pressure readings as a cause of performance issues, such as hesitation or poor acceleration, to restore proper engine response. Notes - Use the listed part numbers (0051535028, 0061531328, A0041533228) to confirm the correct fit. - If you need help confirming compatibility, we are available to assist to minimize the chance of incorrect parts or returns.
