P2749 indicates that the powertrain control module (PCM) has detected an abnormal signal from the intermediate shaft speed sensor 'C' circuit, which is used to monitor the rotational speed of an intermediate shaft inside the transmission. The PCM compares this signal with other speed sensors and sets the code when the expected voltage or signal pattern is not present.
