Weichai 612630120004 Intake Pressure Temperature Sensor

The 612630120004 is an intake manifold absolute pressure (MAP) and temperature sensor designed for Weichai high-speed diesel engines. It measures intake air pressure and temperature to provide critical data for the engine control unit (ECU) to optimize fuel injection timing and quantity. This sensor is engineered for Weichai WP10, WP12, and WP13 engine series, widely deployed in Sinotruk Howo, Shacman X3000, Foton, and Dongfeng heavy-duty trucks, as well as mobile truck cranes. The housing utilizes ABS and aluminum alloy construction to withstand harsh under-hood environments including vibration, thermal cycling, and exposure to hydrocarbons. It operates on a 5V DC supply voltage with a 0.5V to 4.5V analog output signal proportional to absolute pressure. The unit weighs approximately 0.1 kg. Cross-reference includes Bosch part number 0281002576.
