The invention provides a plug connector detection circuit and method and an automobile circuit system. The plug connector detection circuit comprises a signal generation circuit and a detection circuit. The signal generation circuit is connected with one end of the plug connector, and the signal generation circuit is used for sending a detection signal with a preset frequency to the plug connector. A detection circuit is connected to the other end of the plug connector for detecting a frequency of a de-reception signal from the detection signal through the plug connector. According to the plug connector detection circuit and method and the automobile circuit system, the detection signal is sent to the plug connector through the signal generation circuit, the receiving signal of the detection signal after passing through the plug connector is determined through the detection circuit, and the conduction state of the plug connector is determined by judging the frequency of the receiving signal. Therefore, different conduction states such as conduction, disconnection or time-to-time connection of the connector can be detected, and the problem of poor contact detection of the connector is effectively solved.
