P0113 http://www.copartes.com/foros/articulo/160/p0113-obdii-escaner-codigo-diagnosticos-obd2

P1659 tomado de otro foro p1659 = the electronic throttle control system (ETCS) control relay malfunction

aka a relay used in the drive by wire system

"When the voltage from the ETCS control relay is not detected for a set time after the ETCS control relay is turned on when the ignition is turned to ON (ll), or when voltage is not applied for a set time when the throttle actuator (thing that moves the butterfly valve inside throttle body based on gas pedal) is operating, a malfunction in the ETCS control relay power switch is detected and a DTC is stored."

I wouldn't worry about it if the light went away
if it comes back its most likely a failing relay
