Nissan RE0F11A/JF015E/F1CJB Continously Variable Transmission(CVT) P1715, P1720 DTCs Troubleshooting

This vehicle came to our garage with engine running but no throttle, the engine the vehicle speed wasn't going above 15 miles per hour, when you were pressing the accelerator pedal down to the floor the vehicle was jerking and the vehicle wasn't going above 15m/h.
After vsiol inspection we scanned the vehicle and found two DTCs in the Engine control unit (P1715, P1720) but no trouble code was stored in the transmission control unit, when we checked fault codes freeze data frames the fault stored in the engine ECU when the vehicle speed just reached 6 m/h, so we have recorded and uploaded the troubleshooting procedure on our channel to watch and enjoy.
