What P0108 means
Manifold Absolute Pressure/Barometric Pressure Sensor Circuit High
Common causes (general)
Before spending money on parts, verify the code with a scan tool and read freeze frame data. Freeze frame captures every sensor value at the moment the code set — this is often enough to figure out the root cause without further testing.
