P0108 Manifold Absolute Pressure [MAP] Sensor Circuit High Voltage If you have a vacuum guage hook it up and see if the readings change when you apply vacuum. You may need a new MAP sensor The 1 denotes air fuel in your case since it's the map your looking at air or manifold pressure, so it either a bad sensor or a manifold air leak.
