What should the technician enter if the EGR valve will not hold vacuum?

Explanation:
When testing the EGR valve, the key idea is whether the valve can hold vacuum. A functioning EGR valve should seal and maintain vacuum for the test; if it won’t hold vacuum, there’s a leak or a bad diaphragm, so the valve can’t regulate exhaust gases properly. That means the vehicle fails the EGR vacuum test, so the correct entry is Fail. Passing or Vacuum OK would mean the valve holds vacuum, which isn’t the case here, and Not Applicable wouldn’t apply to this test.
