Intake Manifold MAP Pressure Sensor For MAN
51274210216
The Bosch MAP sensor with part number 0281002655 is a critical engine-management component designed to monitor the intake manifold’s absolute pressure in diesel engines (including applications in MAN trucks). By providing accurate pressure readings to the engine control unit (ECU), this sensor enables optimal fuel injection timing, turbocharger boost control and overall combustion efficiency. Manufactured by Bosch, it meets OEM specifications for reliability, durability and performance in heavy-duty diesel service.
Key Features & Benefits
- Genuine Bosch part 0281002655 – Ensures proper fit and compatibility with vehicles specifying this sensor.
- Precise manifold pressure measurement – Enables the ECU to make real-time decisions about fuel quantity, boost control and air-fuel ratio, thereby improving engine responsiveness and efficiency.
- Robust design for heavy-duty use – Built to withstand harsh operating environments found in commercial trucks (high temperatures, vibration, soot, pressure fluctuations).
- Enhanced fuel efficiency & lower emissions – With accurate pressure data, the engine can optimise fuel delivery and turbo boost, leading to better fuel economy and reduced exhaust emissions.
- Smooth engine performance & quick diagnostics – A well-functioning MAP sensor helps eliminate rough idling, sluggish throttle response or faulty boost behaviour and reduces the likelihood of diagnostic trouble-codes related to pressure sensing.
- Direct-replacement quality – Fits into the existing sensor mount, wiring connector and calibrations of compatible MAN engines, simplifying installation without modifications.
Application & Fitment Notes
- Confirm your vehicle or engine model requires the Bosch part number 0281002655. This number is commonly specified for certain MAN diesel engine platforms.
- Install the sensor in the correct intake manifold location, ensuring a clean seal and proper torque to avoid leaks or signal errors.
- After installation, clear any ECU fault codes and perform a test drive to verify proper boost behaviour and that no faults return.
- If prior symptoms include: excessive turbo lag, fluctuating boost pressure, poor fuel economy, engine warning lights or inconsistent idle/response — this sensor replacement may resolve those issues.
