Q: What does code P2745 mean?

Intermediate Shaft Speed Sensor 'B' Circuit. P2745 indicates that the powertrain control module (PCM) has detected an abnormal signal from the intermediate shaft speed sensor 'B' 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 correlation or voltage pattern is not present.
