What does code P0907 mean?

Q: What does code P0907 mean?

Gate Select Position Circuit High. P0907 indicates that the transmission control module (TCM) has detected an abnormally high voltage on the gate select position circuit, which is used to confirm the position of the gear selector gate. The circuit typically operates between 0 and 5 volts, and a high reading means the signal wire is seeing voltage above the expected range, often near battery voltage, which the TCM interprets as a fault.
