Hi, in the service manual, Chapter 4, the only thing close to that number is P0107

“IAP&TS (Pressure function) Circuit Low Voltage or Open”

The sensor should produce following voltage.
0.15 V ≦ Sensor output voltage
Without the above range for 2.2 sec. and more, the code P0107
is indicated.

Intake air pressure & temperature sensor, lead wire / coupler
connection.

or P0117 “WTS Circuit Low Voltage”

The sensor voltage should be the following.
0.1 V ≦ Sensor output voltage
Without the above range for 6.25 sec. and more, the code P0117
is indicated

Water temperature sensor, lead wire / coupler connection.

I don’t know if any of these are even close. The Dealer should have the Hyosung Diagnostic Tool that uses PC_Scan and attaches to the 4 connector near battery. I have and and used it on a bike that has a P0210 injector error. It will read code and give instructions. It can also test the ECU.
