DTC codes / P27xx · Transmission / P2767
P2767 means the transmission control module (TCM) is not receiving any signal from the input/turbine speed sensor 'B' circuit, so it cannot accurately measure how fast the transmission input shaft is spinning. The TCM sets this code when the circuit voltage stays outside the expected range or no pulses arrive while the vehicle is operating.
Guidance is general and written for all OBD-II vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
