CO
ON-VEHICLE INSPECTION
1. INSPECT COOLING FAN SYSTEM
(a) Put the vehicle in the following conditions:
(1) The engine switch is off.
(2) The coolant temperature is less than 95
C
(203
F).
(3) The battery voltage is between 9 and 14 V.
(4) The A/C switch is OFF.
(b) Clamp the 400 A probe of an ammeter over the M+
wire of each cooling fan motor.
(c) Turn the ignition switch to the ON position and wait
for approximately 10 seconds. Check that the fan
stops.
(d) Start the engine. Check that the fan stops with the
engine idling.
HINT:
• Make sure that the radiator engine coolant
temperature is less than 95
C (203F).
• Turn the A/C switch OFF.
(e) Check that the fan operates when the A/C switch is
turned ON (MAX COOL and the magnetic clutch is
operating).
Standard current
HINT:
The coolant temperature is less than 95
C (203F).
(f) Check that the fan operates when the engine
coolant temperature sensor connector is
disconnected.
Standard current
Item Specified Condition
No. 1 cooling fan motor 5 to 14 A
No. 2 cooling fan motor 4 to 12 A
Item Specified Condition
No. 1 cooling fan motor 5 to 19 A
No. 2 cooling fan motor 4 to 16 A

2GR-FE IGNITION – IGNITION COIL AND SPARK PLUGIG–7
IG
(3) Check the spark plug (See page EM-1).
Result
(4) Check the power supply to the ignition coil.
1. Turn the ignition switch to the ON position.
2. Check that there is battery voltage at the
ignition coil positive (+) terminal.
Result
(5) Measure the resistance of the crankshaft
position sensor (See page ES-514).
Result
(6) Check the IGT signal from the ECM (See page
ES-233)
Result
(e) Using a 16 mm (0.63 in.) plug wrench, install the
spark plugs.
Torque: 18 N*m (184 kgf*cm, 13 ft.*lbf)
(f) Connect the 6 fuel injector connectors.
(g) Install the ignition coil assembly (See page IG-10).
2. INSPECT SPARK PLUG
NOTICE:
• Never use a wire brush for cleaning.
• Never attempt to adjust the electrode gap on a
used spark plug.
(a) Check the electrode.
(1) Using a megohmmeter, measure the insulation
resistance.
Standard insulation resistance:
10 M
or higher
HINT:
• If the result is 10 M
or less, clean the plug
and measure the resistance again.
• If a megohmmeter is not available, perform
the following simple inspection instead.
(b) Alternative inspection method:
(1) Quickly accelerate the engine to 4000 rpm 5
times.
