Order of inspection
P0108 Manifold Absolute Pressure/Barometric Pressure Circuit High Input Medium
The P0108 code means the manifold pressure sensor voltage went above the highest value it can possibly produce. That amounts to saying there is no vacuum in the intake, which a running engine cannot do. It is usually caused by a disconnected hose, a short to a voltage line or an open ground.
