P0122 = Throttle/Pedal Position Sensor/Switch A Circuit Low Input

P0123 = Throttle/Pedal Position Sensor/Switch A CircuitHigh Input

Sounds like these are contradictory codes getting both high and low input from the throttle position sensor. Check the circuit for that sensor for shorts to battery and/or ground. By the way, it's very difficult to understand what you are trying to say with your post. Try reading it back to yourself after writing it before posting it up and you might be able to clarify it somewhat so people can understand what you are asking.
