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.

NOTICE
Remember that battery and ignition
cables carry high currents or volt-
ages. Be careful of accidentally
causing a short circuit.
Add only ªToyota Super Long Life
Coolantº or similar high quality eth-
ylene glycol based non±silicate,
non±amine, non±nitrite, and non±bo-
rate coolant with long±life hybrid
organic acid technology to fill the
radiator. ªToyota Super Long Life
Coolantº is a mixture of 50% cool-
ant and 50% deionized water (for
the U.S.A.) or 55% coolant and 45%
deionized water (for Canada).
If you spill some of the coolant, be
sure to wash it off with water to
prevent it from damaging the parts
or paint.
Do not allow dirt or anything else
to fall through the spark plug holes.
Use only spark plugs of the speci-
fied type. Using other types will
cause engine damage, loss of per-
formance or radio noise.
Do not reuse iridium±tipped spark
plugs by cleaning or regapping.
Do not overfill automatic transmis-
sion fluid, or the transmission
could be damaged.
Do not drive with the air cleaner
filter removed, or excessive engine
wear could result. Also backfiring
could cause a fire in the engine
compartment.
Be careful not to scratch the glass
surface with the wiper frame.
When closing the engine hood,
check to see that you have not for-
gotten any tools, rags, etc.
Here is a list of parts and tools you will
need to perform do±it±yourself mainte-
nance. Remember all Toyota parts are de-
signed in metric sizes, so your tools must
be metric.
CHECKING THE ENGINE OIL LEVEL
Parts (if level is low):
ªToyota Genuine Motor Oilº or equiva-
lent
See page 425 in Section 7±2 for de-
tails about engine oil selection.
Tools:
Rag or paper towel
Funnel (only for adding oil)
CHECKING THE ENGINE COOLANT
LEVEL
Parts (if level is low):
ªToyota Super Long Life Coolantº or
similar high quality ethylene glycol
based non±silicate, non±amine, non±ni-
trite, and non±borate coolant with long±
life hybrid organic acid technology.
ªToyota Super Long Life Coolantº is a
mixture of 50% coolant and 50% deion-
ized water (for the U.S.A.) or 55%
coolant and 45% deionized water (for
Canada).
