P2746Intermediate Shaft Speed Sensor 'B' Circuit Range/Performance

P2746 indicates that the powertrain control module (PCM) has detected an out-of-range or erratic signal from the intermediate shaft speed sensor 'B' circuit, which is used to monitor the speed of a rotating shaft inside the transmission. The PCM compares this signal against expected values from other speed sensors and sets the code when the correlation falls outside the programmed performance window.
