Yuchai J5700-3823140 Intake Pressure Temperature Sensor Assembly

The J5700-3823140 is a manifold absolute pressure (MAP) and intake air temperature sensor assembly designed for Yuchai natural gas (CNG/LNG) engines. It integrates pressure and temperature measurement functions into a single housing to monitor intake manifold conditions for the engine control unit (ECU). The sensor utilizes a silicon-based pressure sensing element and a thermistor for temperature detection, packaged in an ABS housing with a rectangular electrical connector. It is engineered to withstand the vibration, thermal shock, and chemical exposure typical of heavy-duty commercial vehicle engine compartments. This unit serves as a direct replacement for Yuchai part numbers J5700-3823140, J5700-3823140A, and J3D00-3823140. Cross-references include Continental/VDO numbers A2C14105500, A2C53328771, A2C53326771 and industry standard designations TMAPC51C, TMAPC59C, and 4921322. Primary applications cover Yuchai YC6L and YC6G series gas engines installed in Sinotruk Howo Sinotruk Howo, Foton Auman, Shaanxi heavy-duty trucks, and Yutong transit buses.
