DTC codes / P27xx · Transmission / P2746
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.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
