CHECK OUTPUT SIGNAL FROM ECM.
1)Turn the ignition switch to
ON.
2)Measure the voltage between ECM and
chassis ground.

CHECK HARNESS BETWEEN PURGE CON.
TROL SOLENOID VALVE AND ECM CON-
NECTOR.
1)Turn the ignition switch to
OFF.
2)Disconnect the connectors from purge con-
trol solenoid valve and ECM.
3)Measure the resistance
of
harness between
purge control solenoid valve connector and
engine ground.
