Answer 1

P0108  Manifoldabsolute pressure (MAP) high input.

What this code is ,a disconnection of the MAP sensor, The MAP is a 3 wire sensor that measure intake manifold pressure. ECM uses MAP signal to help determine engine load. As you increase the vehicle load,the MAP signal voltage decrease thus giving more fuel and ignition timing. P0108 The ECM see the input as 4.6 volts.and no MAP changes this can be caused by a harness connector causing the ECM to see a disconnection,or the MAP itself,
