Following are vacuum magrams for most of the
engine and emissions package combinations covered
by this manual Because vacuum circuits will vary
based on various engine and vehicle options, always
refer first to the vehicle emission control Information
label, if present. Should the label be missing, or
should vehicle be equipped with a different engine
from the vehicle’s original equipment, refer to the di-
agrams below for the same or similar configuration.
If you wish to obtain a replacement emissions la-
bel, most manufacturers make the labels available for
lurchase. The labels can usually be ordered from a
ocal dealer.
A vacuum diagram is typically affixed to a
label in the engine compartment
