Vapor Vent Solenoid Circuit Test
Remove the electrical connector from the vapor
vent solenoid.
Use the diode test function of a digital multimeter
with appropriate test probe leads to check the sig-
nal circuit.
Connect the negative meter lead to the wire listed
in the table, connect the positive meter lead to
engine ground.

No reading (OL or ) indicates an open circuit.
•
A reading of zero (0) indicates an short circuit.
Isolate the faulty component. Check wiring and
connections. Repair or replace faulty wiring.
Use a digital multimeter with appropriate test
probe leads to measure the resistance of the
vapor vent solenoid ground circuit.
Connect the positive meter lead to the engine har-
ness connector wire listed in the table. Connect
the negative meter lead to engine ground.
