Switch or Sensor location causing 520275 code??

After having the throttle cut out on me a few times the other day I found this code shown. I was not on the gas and brake at the same time, yet it did it numerous times. Each time I was able to let off the throttle and hit the gas again and go. I see this code has been mentioned before on here, but I am having a hard time finding what switch or sensor it references. Does anyone know where this switch or sensor would be located that would cause this?
Its under warranty and I will take it to the dealer, but after sending the picture to the dealer the service guy has not seen this issue yet and I want to help find the cause so its in and out of the shop as fast as possible.

Thanks in advance for any help or advice!
