2 − GroundConstantContinuity
If continuity is not as specified, inspect the wire harness or
ground point.
26. INSPECT ENGINE OIL LEVEL WARNING LIGHT
(a) Disconnect the connector from the switch.
(b) Ground terminal 1 on the wire harness connector.
(c) Turn the ignition switch ON, and check that the warning
light lights up approximately 40 seconds later.
If the warning light does not light up, inspect bulb or wire har-
ness.
27. INSPECT LIGHT CONTROL RHEOSTAT

DTC P0335 Crankshaft Position Sensor ”A” Circuit Malfunction
CIRCUIT DESCRIPTION
The crankshaft position sensor (NE signal) consists of a signal plate and pick up coil. The NE\
signal plate
has 24 teeth and is built into the distributor. When the camshaft rotates, the protrusion on the signal plate
and the air gap on the pick up coil change, causing fluctuations in the magnetic field and generating an elec-
tromotive force in the pick up coil. The NE signal sensor generates 24 signals fo\
r every engine revolution.
The ECM detects the standard crankshaft angle based on the G1, G2 signals, \
detects the actual crankshaft
angle and the engine speed by the NE signals, and detects misfire by NE2 sign\
als.

te and a pick up coil. The G1, G2,
signal plates each have one tooth on the outer circumference and are built int\
o the distributor. When the
camshaft rotates, the protrusion on the signal plate and the air gap on the pick \
up coil change, causing fluc-
tuations in the magnetic field and generating an electromotive force in the pick \
up coil. The ECM detects the
standard crankshaft angle based on the G1, G2 signals, detects the actual cranks\
haft angle and engine
speed by the NE signals, and detects misfire by NE2 signals.

CIRCUIT DESCRIPTION
The crankshaft position sensor (NE2 signal) consists of a signal plate and a pick up coil. The NE2 signal plate
has 34 teeth and is mounted on the crankshaft. When the crankshaft rotates, the protrusion on the signal
plate and the air gap on the pick up coil change, causing fluctuations i\
n the magnetic field and generating
an electromotive force in the pick up coil. The NE2 signal sensor generate\
s 34 signals for every engine revo-
lution. The ECM detects the standard crankshaft angle based on G1, G2 signals d\
etects the actual crank-
shaft angle and the engine speed by NE signals, and detects misfire by NE2 si\
gnals.

1996 LAND CRUISER (RM451U)
DTC31, 32, 33, 34, 35, 36 Speed Sensor Circuit
CIRCUIT DESCRIPTION
The speed sensor detects wheel speed and sends the ap-
propriate signals to the ECU. These signals are used to control
the ABS system. The front and rear rotors each have 48 serra-
tions.
When the rotors rotate, the magnetic field emitted by the perma-
nent magnet in the speed sensor generates an AC voltage.
Since the frequency of this AC voltage changes in direct propor-
tion to the speed of the rotor, the frequency is used by the ECU
to detect the speed of each wheel.
DTC No.DTC Detecting ConditionTrouble Area

Detection of any of conditions (1) through (3):
(1) At vehicle speed of 10 km/h (6 mph) or more, pulses are
not input for 5 sec.
(2) Momentary interruption of the speed sensor signal oc-
curs at least 7 times in the time between switching the igni-
tion switch ON and switching it OFF.
(3) Abnormal fluctuation of speed sensor signals with the
vehicle speed 20 km/h (12 mph) or more.

DTC No. 33 is for the right rear speed sensor.

DTC No. 34 is for the left rear speed sensor.
Fail safe function:
If trouble occurs in the speed sensor circuit, the ECU cuts off current to the ABS control (solenoid) relay and
prohibits ABS control.

LUBRICATION OIL AND FILTER
1996 LAND CRUISER (RM451U)
REPLACEMENT
CAUTION:
Prolonged and repeated contact with mineral oil will result
in the removal of natural fats from the skin, leading to dry-
ness, irritation and dermatitis. In addition, used engine oil
contains potentially harmful contaminants which may
cause skin cancer.Care should be taken, therefore, when
changing engine oil to minimize the frequency and length
of time your skin is exposed to used engine oil. Protective
clothing and gloves that cannot be penetrated by oil should
be worn. The skin should be thoroughly washed with soap
and water, or use water−less hand cleaner, to remove any
used engine oil. Do not used gasoline, thinners, or sol-
vents.In order to preserve the environment, used oil and
used oil filters must be disposed of only at designated dis-
posal 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 09228−44011
(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
