INSPECTION
1.
INSPECT FRONT ENGINE INSULATOR
(a)
Using MITYVAC (Hand–Held Vacuum Pump), apply vac-
uum of 80 kPa (600 mmHg, 25 in.Hg) and allow it to stand
for 1 minutes.
(b)
Check that there is no change in the needle movement.
(c)
Check that there is no fluid leakage caused by a break of
a lower diaphragm.
If the operation is not as specified, replace the insulator.
2.
INSPECT VSV FOR ACTIVE CONTROL ENGINE
MOUNT
(a)
Inspect the VSV for open circuit.
Using an ohmmeter, check that there is continuity be-
tween the terminals.
Resistance: 18 – 22 Ω at 20°C (68°F)
If there is no continuity, replace the VSV.
(b)
Inspect VSV for ground.
Using an ohmmeter, check that there is no continuity be-
tween each terminal and the body.
If there is continuity, replace the VSV.
(c)
Inspect VSV operation.
(1)
Check that air flows from port G to port E.
(2)
Apply battery positive voltage across the terminals.
(3)
Check that air flows from port F to port E.
If operation is not as specified, replace the VSV.
