潍柴轻卡压差传感器 31293659/0281006208 原厂标准替换件

When your Weichai light truck experiences power loss, delayed acceleration, or the engine fault light on the dashboard with a "Turbo Boost Pressure异常" fault code, it usually indicates the differential pressure sensor has aged or failed and cannot accurately monitor the pressure difference between the intake manifold and the turbocharger. In normal operation, this sensor feeds the ECU with differential pressure signals to help precisely control fuel and intake, ensuring smooth power output and good fuel economy. This product is an OEM-standard replacement, OEM part number 0281006208 (compatible with 0281006207), for Weichai WP-series light truck engines. Installation notes: disconnect the battery negative first, clean the sensor mounting surface to prevent dirt from entering the line; after installation, use a diagnostic tool to clear historical fault codes and perform sensor adaptive learning.
