VSV EGR - Vacuum switchover valve for EGR
1. Check the continuity between openings. Spec-
ifications: there must be continuity between open-
ings G and E. There must not be continuity
between openings E and F.
2.Apply voltage to the connector terminals of the
vacuum switchover valve and check continuity be-
tween the openings. Specifications: there must be
continuity between openings E and F. There must
not be continuity between openings G andE.
3.Measure the resistance value between the ter-
minals.
Characteristic
