Best answer

P0108 MAP sensor voltage too high

P0456 EVAP leak monitor small leak detected

The MAP sensor is the manifold absolute sensor, whenever there is a code condition that is circuit high voltage, this represenst a disconnection at the sensor check the connection and the harness of the MAP sensor As for P0456 inspect the fuel cap which is more of the cause for a small evap leak, replace if the fuel cap if the seal or  seal are worn
