INSPECTION
1. INSPECT INTAKE AIR CONTROL VALVE
(a) With 39.9 kPa (300 mmHg, 11.8 in.Hg) of vacuum applied
to the actuator, check that the actuator rod moves.
(b) One minute after applying the vacuum in step (a), check
that the actuator rod does not return.
If the operation is not as specified, replace the intake manifold.
2. INSPECT VSV
(a) Using an ohmmeter, check that there is continuity be-
tween each terminal.
Resistance: 33 to 39 W at 20°C (68°F)
If there is no continuity, replace the VSV.
(b) Using an ohmmeter, check that there is no continuity be-
tween each terminal and the body.
If there is continuity, replace the VSV.
(c) Check that air flows from port E to the filter.
(d) Apply battery voltage across the terminals.
(e) Check that air flows from port E to port F.
If operation is not as specified, replace the VSV.
