1. INSPECT SPARK TEST
Check that the spark occurs.
(1) Remove the ignition coils (with igniters) (See page
IG-5).
(2) Remove the spark plugs.
(3) Install the spark plug to the ignition coil, and connect
the ignition coil connector.
(4) Ground the spark plug.
(5) See if spark occurs while engine is being cranked.
NOTICE:
To prevent gasoline from being injected from injectors dur-
ing this test, crank the engine for no more than 5 - 10 se-
conds at time.
If the spark does not occur, do the test as follows:

2. INSPECT SPARK PLUGS
NOTICE:

Never use a wire brush for cleaning.

Never attempt to adjust the electrode gap on a used
spark plug.

Spark plugs should be replaced every 193,000 km
(120,000 miles).
(a) Remove the 6 ignition coils (with igniters) (See page
IG-5).
(b) Inspect the electrode.

Using a megger (insulation resistance meter), mea-
sure the insulation resistance.
Standard correct insulation resistance:
10 MW or more
If the resistance is less than specified, proceed to step (d).
HINT:
If a megger is not available, these simple method of inspection
provides fairly accurate results.

Simple Method:

Quickly race the engine to 4,000 rpm 5 times.

Remove the spark plug (See step (c)).

Visually check the spark plug.
If the electrode is dry ... OK
If the electrode is wet ... Proceed to step (d)

Reinstall the spark plug (See step (g)).
(c) Using a 16 mm plug wrench, remove the 6 spark plugs.
(d) Visually check the spark plug for thread damage and insu-
lator damage.
If abnormal, replace the spark plug.
Recommended spark plug:
DENSO madeSK20R11
NGK madeIFR6A11
(e) Inspect the electrode gaps.
Maximum electrode gap for used spark plug:
1.3 mm (0.051 in.)
If the gap is greater than maximum, replace the spark plug.
Correct electrode gap for new spark plug:
1.1 mm (0.043 in.)
NOTICE:
If adjusting the gap of a new spark plug, bend only the base
of the ground electrode. Do not touch the tip. Never attempt
to adjust the gap on the used plug.

2. FOR VEHICLES EQUIPPED WITH A CATALYTIC CONVERTER
CAUTION:
If large amount of unburned gasoline flows into the converter, it may overheat and create a fire haz-
ard. To prevent this, observe the following precautions and explain them to your customer.
(a) Use only unleaded gasoline.
(b) Avoid prolonged idling.
Avoid running the engine at idle speed for more than 20 minutes.
(c) Avoid spark jump test.
(1) Perform spark jump test only when absolutely necessary. Perform this test as rapidly as possible.
(2) While testing, never race the engine.
(d) Avoid prolonged engine compression measurement.
Engine compression tests must be done as rapidly as possible.
(e) Do not run engine when fuel tank is nearly empty.
This may cause the engine to misfire and create an extra load on the converter.
(f) Avoid coasting with ignition turned off.
(g) Do not dispose of used catalyst along with parts contaminated with gasoline or oil.
3. IF VEHICLE IS EQUIPPED WITH MOBILE COMMUNICATION SYSTEM
For vehicles with mobile communication systems such as two-way radios and cellular telephones, observe
the following precautions.
(1) Install the antenna as far as possible away from the ECU and sensors of the vehicle's electronic
system.
(2) Install the antenna feeder at least 20 cm (7.87 in.) away from the ECU and sensors of the ve-
hicle's electronic systems. For details about ECU and sensors locations, refer to the section on
the applicable component.
(3) Avoid winding the antenna feeder together with other wiring as much as possible, and also avoid
running the antenna feeder parallel with other wire harnesses.
(4) Check that the antenna and feeder are correctly adjusted.
(5) Do not install powerful mobile communications system.
4. FOR USING OBD II SCAN TOOL OR TOYOTA HAND-HELD TESTER
CAUTION:
Observe the following items for safety reasons:

Before using the OBD II scan tool or TOYOTA hand-held tester, the OBD II scan tool's instruc-
tion book or TOYOTA hand-held tester's operator manual should be read thoroughly.

Be sure to route all cables securely when driving with the OBD II scan tool or TOYOTA hand-
held tester connected to the vehicle. (i.e. Keep cables away from feet, pedals, steering wheel
and shift lever.)

Two persons are required when test driving with the OBD II scan tool or TOYOTA hand-held
tester, one person to drive the vehicle and the other person to operate the OBD II scan tool or
TOYOTA hand-held tester.

REPAIR INSTRUCTIONS
GENERAL INFORMATION
BASIC REPAIR HINT
(a) Use fender, seat and floor covers to keep the vehicle
clean and prevent damage.
(b) During disassembly, keep parts in the appropriate order
to facilitate reassembly.
(c) Installation and removal of battery terminal:
(1) Before performing electrical work, disconnect the
negative (-) terminal cable from the battery.
(2) If it is necessary to disconnect the battery for in-
spection or repair, first disconnect the negative (-)
terminal cable.
(3) When disconnecting the terminal cable, to prevent
damage to battery terminal, loosen the cable nut
and raise the cable straight up without twisting or
prying it.
(4) Clean the battery terminals and cable ends with a
clean shop rag. Do not scrape them with a file or oth-
er abrasive objects.
(5) Install the cable ends to the battery terminals after
loosening the nut, and tighten the nut after installa-
tion. Do not use a hammer to tap the cable ends
onto the terminals.
(6) Be sure the cover for the positive (+) terminal is
properly in place.
(d) Check hose and wiring connectors to make sure that they
are connected securely and correctly.
(e) Non-reusable parts
(1) Always replace cotter pins, gaskets, O-rings, oil
seals, etc. with new ones.
(2) Non-reusable parts are indicated in the component
illustrations by the ºº symbol.
(f) Precoated parts
Precoated parts are bolts, nuts, etc. that are coated with
a seal lock adhesive at the factory.
(1) If a precoated part is retightened, loosened or
caused to move in any way, it must be recoated with
the specified adhesive.
(2) When reusing precoated parts, clean off the old
adhesive and dry with compressed air. Then apply
the specified seal lock adhesive to the bolt, nut or
threads.

OIL AND FILTER
INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SJ, Energy-Conserving or ILSAC multi-
grade engine oil.
SAE 5W - 30 is the best choice for your vehicle, for
good fuel economy, and good starting in cold weath-
er.
2. CHECK ENGINE OIL LEVEL
After warm up the engine and then 5 minutes after the engine
stop, oil level should be between the low level and full level
marks on the dipstick.
If low, check for leakage and add oil up to the full level mark.
NOTICE:
Do not fill with engine oil above the full level mark.
3. REMOVE OIL PRESSURE SWITCH, AND INSTALL
OIL PRESSURE GAUGE
(a) Using SST, remove the oil pressure switch.
SST 09816-30010
(b) Install the oil pressure gauge.
4. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
5. CHECK OIL PRESSURE
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.3 psi) or more
At 3,000 rpm294 - 539 kPa (3.0 - 5.5 kgf/cm2, 43 - 78 psi)

REPLACEMENT
CAUTION:

Prolonged and repeated contact with mineral oil will
result in the removal of natural fats from the skin,
leading to dryness, irritation and dermatitis. In addi-
tion, used engine oil contains potentially harmful
contaminants which may cause skin cancer.

Exercise caution in order to minimize the length and
frequency of contact of your skin to used oil. Wear
protective clothing and gloves. Wash your skin thor-
oughly with soap and water, or use water-less hand
cleaner, to remove any used engine oil. Do not use
gasoline, thinners, or solvents.

In order to preserve the environment, used oil and
used oil filter must be disposed of only at designated
disposal sites.
1. DRAIN ENGINE OIL
(a) Remove the oil filler cap.
(b) Remove the oil drain plug, and drain the oil into a contain-
er.
2. REPLACE OIL FILTER
(a) Using SST, remove the oil filter.
SST 09228-07501
(b) Check and clean the oil filter installation surface.
(c) Apply clean engine oil to the gasket of a new oil filter.
(d) Lightly screw the oil filter into place, and tighten it until the
gasket contacts the seat.
(e) Using SST, tighten it an additional 3/4 turn.
