FUEL CUT RPM
INSPECTION
1. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
2. CONNECT TOYOTA HAND-HELD TESTER OR OBDII
SCAN TOOL
(a) Remove the fuse cover on the instrument panel.
(b) Connect the TOYOTA hand-held tester or OBDII scan
tool to the DLC3.
(c) Please refer to the TOYOTA hand-held tester or OBDII
scan tool operator's manual for futher details.
3. INSPECT FUEL CUT OFF PRM
(a) Increase the engine speed to at least 2,500 rpm.
(b) Use a sound scope to check for injector operating noise.
(c) Check that when the throttle lever is released, injector op-
eration noise stops momentarily and then resumes.
HINT:
Measure with the A/C OFF.
Fuel return rpm: 900 rpm
4. DISCONNECT TOYOTA HAND- HELD TESTER OR
OBDII SCAN TOOL

INSPECTION
INSPECT THERMOSTAT
HINT:
The thermostat is numbered with the valve opening tempera-
ture.
(a) Immerse the thermostat in water, and gradually heat the
water.
(b) Check the valve opening temperature.
Valve opening temperature: 80 - 84°C (176 - 183°F)
If the valve opening temperature is not as specified, replace the
thermostat.
(c) Check the valve lift.
Valve lift: 8 mm (0.31 in.) or more at 95°C (203°F)
If the valve lift is not as specified, replace the thermostat.
(d) Check that the valve is fully closed when the thermostat
is at low temperatures (below 40°C (104°F)).
If not closed, replace the thermostat.

ELECTRIC COOLING FAN
ON-VEHICLE INSPECTION
1. CHECK COOLING FAN OPERATION WITH LOW TEM-
PERATURE (Below 83°C (181°F))
(a) Turn the ignition switch ON.
(b) Check that the cooling fan stops.
If not, check the cooling fan relay and ECT switch, and check
for a separated connector or severed wire between the cooling
fan relay and ECT switch.
(c) Disconnect the ECT switch connector.
(d) Check that the cooling fan rotates.
If not, check the engine main relay, cooling fan relay, cooling
fan, fuses, and check for short circuit between the cooling fan
relay and ECT switch.
(e) Reconnect the ECT switch connector.
2. CHECK COOLING FAN OPERATION WITH HIGH TEM-
PERATURE (Above 94°C (201°F))
(a) Start the engine, and raise coolant temperature to above
94°C (201°F).
(b) Check that the cooling fan rotates.
If not, replace the ECT switch.
3. INSPECT NO.1 COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter.
(c) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
Standard amperage:
M/T5.7 - 7.7 A
A/T8.6 - 11.6 A
(d) Reconnect the cooling fan connector.
4. INSPECT NO.2 COOLING FAN
(a) Disconnect the cooling fan connector.
(b) Connect battery and ammeter.
(c) Check that the cooling fan rotates smoothly, and check
the reading on the ammeter.
Standard amperage: 6.4 - 7.4 A
(d) Reconnect the cooling fan connector.

INSPECTION
1. DRAIN ENGINE COOLANT
2. REMOVE ECT SWITCH
3. INSPECT ECT SWITCH
(a) Using an ohmmeter, check that there is no continuity be-
tween the terminals when the coolant temperature is
above 94°C (201°F).
If there is continuity, replace the switch.
(b) Using an ohmmeter, check that there is continuity be-
tween the terminals when the coolant temperature is be-
low 83°C (181°F).
If there is no continuity, replace the switch.
4. REINSTALL ECT SWITCH
5. REFILL WITH ENGINE COOLANT
6. START ENGINE AND CHECK FOR COOLANT LEAKS
