The 2 codes you got from your Expedition,

P2104 (Throttle Actuator Control (TAC) Forced Idle

P2112(Throttle Actuator Control(TAC) Stuck Closed

Could be a small glitch in the Electronic Throttle Body. Clear the codes from the computers memory and drive the vehicle. See if the Wrench light comes back on and see if you have any problems with the gas pedal and accellerating the vehicle. If you do, the throttle body will need to be replaced. If no problem returns, it would be an intermittant problem and till it returns, do not perform any repairs. As I stated earlier, it may have been a small glitch in the throttle body. With the what we call Drive By Wire system. There is no throttle cable anymore, the throttle body is driven by sensors and electronics.
