DTC codes / P09xx · Transmission / P0952
P0952 indicates that the transmission control module (TCM) has detected a low-voltage condition on the electrical circuit for the auto shift manual control, which is the driver-operated gear selection input for an automated manual or dual-clutch transmission. The computer expects a specific voltage range on the signal circuit and sees a value below the acceptable threshold, which can prevent the TCM from knowing the driver's intended gear or mode.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
