Automotive Intake Manifold Temperature and Pressure Integrated Sensor (TMAP)
Product Introduction
This intake manifold temperature and pressure integrated sensor (TMAP) real‑time collects the dynamic changes of air pressure and temperature inside the engine intake manifold, and accurately converts physical pressure and temperature signals into standard electrical signals for transmission to the engine ECU.
It provides core data support for the ECU to accurately calculate basic fuel injection quantity, match optimal ignition timing, optimize air‑fuel ratio control and adjust vehicle power performance. It is a key core component of the automotive engine electronic control system.
Integrating dual detection functions of temperature and pressure, the sensor features high measurement accuracy, high induction sensitivity, excellent operational stability, low static power consumption, strong anti‑interference capability and long‑term service reliability. It is perfectly compatible with power systems of passenger vehicles, commercial vehicles, construction machinery and other equipment.
