DTC codes / P09xx · Transmission / P097F
P097F indicates that the transmission control module (TCM) has detected an open circuit or excessive resistance in the control circuit for shift solenoid F, which is responsible for controlling a specific gear shift. The computer commands the solenoid to change state but does not see the expected electrical response, so it sets this code and may default to a limp-home 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.
