Here is what each of your trouble codes means:
DTC P0108 MAP Sensor Range check High
DTC P0121 TPS Circuit Range/Performance Problem
DTC P0340 Camshaft Position Sensor Circuit Malfunction
Do you know how long each of these codes have been stored? Each one of these codes relate to a different part of the vehicle.
Your PO108 codes is probably a faulty Manifold Absolute Pressure Sensor
PO121 is a Throttle Position Sensor malfunction code
PO340 is a Camshaft Position Sensor malfunction code
I would not think that all 3 of these codes all set at the same time, just wouldnt make sense unless there was a problem with the Engine Control Module (ECM) causing all these codes to set at the same time.
