SENSOR FAIL
In the Service Software / Vent Flow and Pressure Diagnostics, verify the Manifold Flow counts is
800 ± 250.
Disconnect the White in-line connector in the Manifold Pressure. If the counts return within specified
range, check for occlusions in the Bulkhead harness.
If the counts do not return within the specified range, replace the VIB.
