A machine includes a chassis and an object detection sensor alignment monitoring system. The monitoring system includes a first sensor module coupled to an object detection sensor. The first sensor module measures values of object detection sensor pitch, roll, and yaw. The monitoring system also includes a second sensor module coupled to the chassis. The second sensor module measures values of chassis pitch, roll, and yaw. The monitoring system further includes a control unit. The control unit compares the measured values of the object detection sensor and chassis pitch, roll, and yaw. The control unit determines whether the measured values are within a predefined tolerance. Further, the control unit generates an alert if the measured values of the object detection sensor and chassis pitch, roll, and yaw are beyond the predefined tolerance.
