What happened to the 60-year-old Ford Mondeo who didn't respond when he stepped on the accelerator automatically?

Ford Mondeo's automatic gear didn't respond when stepping on the accelerator in 60 years. Stepping on the accelerator can increase the engine speed. The transmission control unit can't recognize the signal of the gear sensor or the transmission protection, so it goes to the 4S shop computer to detect the fault of the transmission control unit, store it and repair it. The engine speed cannot be increased when stepping on the throttle, and the throttle may be stuck. Check fault storage of throttle and engine control unit.
