Answer 1

P1620 Electronic throttle housing

P1017 ECM control module internal fault

There is no way around this , this is the ECM being at fault, and the ETC (electronic throttle control) , At one time the software had issue where there was uncalled for limp home mode. Check this TSB # NHTSSA06V441000
