In case of heavy snow or rain, a temporary high restriction might occur, which should disappear after drying. If the gauge locks up at the red zone, inspect the elements for damage, reset the gauge, and recheck the reading after reusing the element.

Hold the reset button; if the indicator drops slightly and doesn't move, the vacuum line is leaking. A leak in the gauge itself could also be the problem; repeat the vacuum test, but close the gauge connection airtight this time. If you have a turbocharged engine, ...
