INSPECTION
1. REMOVE EGR GAS TEMPERATURE SENSOR
2. INSPECT EGR GAS TEMPERATURE SENSOR
Using an ohmmeter, measure the resistance between the ter-
minals.
TemperatureResistance
50 °C (122° F)64 − 97 kΩ
100°C (212° F)11 − 16 kΩ
150 °C (302° F)2 − 4 kΩ
If the resistance is not as specified, replace the sensor.
3. REINSTALL EGR GAS TEMPERATURE SENSOR

HEATED OXYGEN SENSOR
INSPECTION
INSPECT HEATER RESISTANCE OF HEATED OXYGEN
SENSORS
(a) Disconnect the heated oxygen sensor connector.
(b) Using an ohmmeter, measure the resistance between ter-
minals +B and HT.
Resistance: 11 − 16 Ω at 20° C (68°F)
If resistance is not as specified, replace the heated oxygen sen-
sor.
(c) Reconnect the heated oxygen sensor connector.

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 OBD II
SCAN TOOL
(a) Remove the fuse cover on the instrument panel.
(b) Connect the TOYOTA hand−held tester or OBD II scan tool to the DLC3.
(c) Please refer to the TOYOTA hand−held tester or OBD II
scan tool operator’s manual for further details.
3. INSPECT FUEL CUTOFF PRM
(a) Increase the engine speed to at least 3,500 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: 1,200 rpm
4. DISCONNECT TOYOTA HAND −HELD TESTER OR
OBD II SCAN TOOL

STEERING SYSTEM
PRECAUTION
Care must be taken to replace parts properly because they could affect the pe\
rformance
of the steering system and result in a driving hazard.
The LAND CRUISER is equipped with SRS (Supplemental Restraint System) suc\
h as the
driver airbag and front passenger airbag. Failure to carry out service o\
peration in the
correct sequence could cause the SRS to unexpectedly deploy during servicing, possi-
bly leading to a serious accident. Before servicing (including removal or \
installation of
parts, inspection or replacement), be sure to read the precautionary notices \
in the RS
section.

POWER STEERING FLUID
BLEEDING
1. CHECK FLUID LEVEL (See page SR−4 )
2. JACK UP FRONT OF VEHICLE AND SUPPORT IT WITH STANDS
3. TURN STEERING WHEEL
With the engine stopped, turn the wheel slowly from lock to lock
several times.
4. LOWER VEHICLE
5. START ENGINE
Run the engine at idle for a few minutes.
6. TURN STEERING WHEEL
(a) With the engine idling, turn the wheel to left or right full lock and keep it there for 2 −3 seconds, then turn the
wheel to the opposite full lock and keep it there for 2 −3 se-
conds.
(b) Repeat (a) several times.
7. STOP ENGINE
8. CHECK FOR FOAMING OR EMULSIFICATION
If the system has to be bled twice specifically because of foam-
ing or emulsification, check for fluid leaks in the system.
9. CHECK FLUID LEVEL (See page SR−4)
