Code P259F
2019, 47K miles - Merging into heavy traffic on a freeway and the tuck bogged down and went into limp mode. The check engine light cam on and I pulled onto to the shoulder. Shut off the engine, waited a few minutes and restarted. The check engine light stayed on an it drove fine the rest of the way home - 50 miles, with 75% of the miles being highway. Kept my eyes on my gauges and boost and temps are normal. When I got home I pulled the code
Since it seem to run fine after I shut it off and restarted, any issue in resetting the the DTC and driving the truck?

DTC sets when the VGT command is greater than a calibrated value for the current amount of boost pressure for more than a calibrated amount of time.

Cause:
- Intake air system leaks between the turbocharger and the intake manifold
- Damaged MAP sensor
- Turbocharger actuator is not responding
- VGT vanes sticking
