潍柴轻卡压差传感器 31293659/0281006208 原厂标准替换件

When Weichai light trucks exhibit power loss, slow acceleration, or the instrument cluster shows check engine with “boost pressure abnormal” code, the diaphragm pressure sensor has aged or failed and cannot accurately monitor pressure difference between intake manifold and turbocharger. In normal operation, this sensor feeds real-time pressure difference signals to the ECU to help precisely control fuel and intake, ensuring smooth power output and good fuel economy. This product is a factory-standard replacement part, OEM number 0281006208 (compatible with 0281006207); fits Weichai WP-series light-duty engines. Installation notes: disconnect the negative battery terminal first; clean the sensor mounting surface to prevent debris entering the line; after installation, use a diagnostic tool to clear historical fault codes and run sensor adaptation learning procedure.
