The invention discloses an automobile temperature and pressure integrated sensor, which comprises a shell and a terminal, an insertion port is arranged at the upper end of the shell, a threaded connection part is arranged at the lower end of the shell, an extension port is arranged at the lower end of the threaded connection part, the lower end of the terminal is buckled with the shell, and a conductive pin is arranged in the terminal. An elastic circuit board, an air pressure sensor and a thermistor support are installed in the shell, a circuit is arranged on the elastic circuit board, the circuit is electrically connected with a conductive contact pin, a conductive rod is connected to the thermistor support, a thermistor is connected to the lower end of the conductive rod, an airflow opening is formed in the thermistor support, and the air pressure sensor and the conductive rod are electrically connected with the circuit. By adopting the design of the elastic circuit board, the sensor is convenient to assemble, and the anti-seismic property of the sensor is improved. By using the open NTC protective sleeve, the thermistor can be effectively protected and prevented from being impacted, the effect of the thermistor is not influenced, and the response speed of the sensor is improved.
