281002576 SENSOR PRESSURE

Detail Information

281002576   SENSOR PRESSURE

Product Name: Intake Pressure Sensor (MAP Sensor — Manifold Absolute Pressure Sensor) — intake pressure monitoring component of the engine electronic control system

Function: Mounted on the intake manifold or boost pipe, the sensor continuously measures the absolute intake manifold pressure (boost pressure) and converts it into an electrical signal for the ECU to precisely control fuel injection quantity, injection timing and the turbocharging system. It directly affects engine power and fuel economy. A faulty sensor typically causes power loss, black smoke, and a warning light (e.g., pressure-related fault codes such as P0106).

Applications:

•  common-rail systems: Weichai, Yuchai, Xichai,other Chinese domestic common-rail diesel engines
• Construction machinery: EC210 and other excavators (compatible with JCB220, SE220, etc.)
• High-boost tuning: BMW N20 / N54 / N55 / S55 engines in 4 BAR pressure upgrade applications

Key Specifications:

• Range: 4 BAR absolute pressure type

Interchangeable Part Numbers: 0281002576  = 281002576; related cross-references include 20524936, 5010437653, 504073323, 1403945, 55219299, 612630120004 (Weichai/Xichai), etc.

Replacement Notes: Verify that the connector matches the original wiring before installation. Ensure the sealing ring is intact and the sensor is tightened properly to prevent air leaks that cause inaccurate readings. After replacement, verify live pressure values with a diagnostic tool.
