The invention discloses a five-wire type air suspension vehicle body height sensor and a vehicle body height control method. The five-wire type air suspension vehicle body height sensor comprises a base, a connecting rod, a bottom shell, a high-position alarm switch, a rotary shifting fork and a low-position alarm switch, the bottom shell and an upper cover form a cavity, an annular resistor discis installed in the cavity formed by the bottom shell and the upper cover, a low-position alarm contact, a high-position alarm contact and a sliding contact are arranged in the cavity, the rotary shifting fork drives a lower sliding contact to slide freely along the annular resistor disc, the two ends of a swing arm rotating shaft are installed on the center hole bearings of the bottom shell and the upper cover respectively, the rotary shifting fork and the swing arm are installed on the swing arm rotating shaft respectively, one side of the connecting rod is a small end, the other side of theconnecting rod is a large end, the swing arm is connected with the small end of the connecting rod, and the large end of the connecting rod is connected with the base. In addition, when the low-position alarm contact or the high-position alarm contact is closed, respective alarm lamps can be turned on. According to the embodiment of the invention, an input signal is provided for the air suspension controller to monitor or adjust the height of a vehicle body in real time.
