according to the list of fault codes, 524261-2 is "ECU 5-Volt Sensor Supply A Incorrect Output" and 522752-9 is "Cam Sensor No Signal".

It seems like the accelerator pedal is not recieving 5v or too much voltage(recieving battery voltage). I would start by disconnecting the accelerator pedal and checking the supply voltage...if the voltage is too low or non their might be a short somewhere or a broken wire..if not then ECU is bad, same if the supply voltage is battery voltage. Now if the supply voltage is 5Volts then it seems like the accelerator pedal is fried and causing a short and causing a incorrect output volage & Sensor no signal.
