Hello - for your P2118 problem - there is a separate fuse for the electronic throttle control (ETCS) - 10a I think - in the engine bay. Check that fuse first to see if the reverse jump killed it (check with a volt meter, not just eyeballs). If that fuse is good, it is probably going to require a throttle body. For hands-on assistance, I recommend a limp mode inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
