The invention discloses engine oil temperature-pressure composite sensors integrating temperature and pressure detection of engine oil. Each sensor comprises a sensor body, a reinforcing block, a positioning plate and a connection port, and is characterized in that a sensing touch block is arranged at one end of the sensor body; the reinforcing block is arranged on the sensor body; the positioning plate is arranged on the reinforcing block; a fixed ring and a connection contact are arranged on the connection port; the fixed ring is arranged on the reinforcing block; and the connection contact is connected with the sensing touch block by a connecting wire. According to the engine oil temperature-pressure composite sensors integrating temperature and pressure detection of engine oil disclosed by the invention, sensors having two functions of temperature and pressure detection of engine oil are combined, so that the quality performance of the sensor is improved, the quantity of sensors also can be reduced, and the wiring harness of vehicle engine can be reduced, and the cost is reduced; moreover, a sealing ring is arranged on the reinforcing block of the sensor body, so that the sealing performance after the mounting of the sensors can be improved, and the stability of the sensors also can be enhanced in a using process.
