Ok, the throttle warning light and check engine light come on in conjunction with each other when a fault is detected in the electronic throttle control system which consists of the APP(accelerator pedal position) sensor on the gas pedal, the PCM(powertrain control module), the electronic throttle body and the wiring harness between each.
Yours is a fly by wire system in which a voltage signal is registered by the APP sensor when you press the gas pedal and that signal is sent to the PCM and then the electronic throttle body. This takes the place of the traditional throttle cable connecting the gas pedal to the throttle body.
If not diagnosed and corrected, a fault in the system can lead to no response when pushing the gas pedal to the throttle body staying in wide open mode where you cant slow the vehicle down.
The only way to know which of the abovementioned components in the fly by wire system is at fault is to have the system scanned for fault codes and then do the required diagnostics and repair
