NORMAL OPERATING CONDITION
DescriptionINFOID:0000000003765606
NOTE:
 Audio operation information, refer to Owner's Manual.
 The majority of the audio concerns are the result of outside causes (bad CD, electromagnetic interference,
etc.).
NOISE
The following noise results from variations in field strength, such as fading noise and multi-path noise, or
external noise from trains and other sources. It is not a malfunction.
 Fading noise: This noise occurs because of variations in the field strength in a narrow range due to moun-
tains or buildings blocking the signal.
 Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the
antenna at a different time from the waves that reflect off mountains or buildings.
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.
Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and opera-
tion of each piece of electrical equipment, and then determine the cause.
NOTE:
The source of the noise can be easily found by listening to the noise while removing the fuses of electrical
components, one by one.
Types of Noise and Possible Causes
Occurrence condition Possible cause
Occurs only when engine is ON.A continuous growling noise occurs. The speed of
the noise varies with changes in the engine speed. Ignition components
The occurrence of the noise is linked with the operation of the fuel pump.  Fuel pump condenser
Noise only occurs when various
electrical components are oper-
ating.A cracking or snapping sound occurs with the op-
eration of various switches. Relay malfunction, audio unit malfunction
The noise occurs when various motors are operat-
ing. Motor case ground

 Open circuit in printed heater
 Poor ground of antenna feeder line
A cracking or snapping sound occurs while the vehicle is being driven, especially when
it is vibrating excessively. Ground wire of body parts
 Ground due to improper part installation
 Wiring connections or a short circuit

P0075, P0081 IVT CONTROL SOLENOID VALVE
P0075, P0081 IVT CONTROL SOLENOID VALVE
DescriptionINFOID:0000000003856523
Intake valve timing control solenoid valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The intake valve timing control solenoid valve changes the oil
amount and direction of flow through intake valve timing control unit
or stops oil flow.
The longer pulse width advances valve angle.
The shorter pulse width retards valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the intake valve angle at the control
position.

P0335 CKP SENSOR (POS)
P0335 CKP SENSOR (POS)
DescriptionINFOID:0000000003856623
The crankshaft position sensor (POS) is located on the oil pan facing
the gear teeth (cogs) of the signal plate. It detects the fluctuation of
the engine revolution.
The sensor consists of a permanent magnet and Hall IC.
When the engine is running, the high and low parts of the teeth
cause the gap with the sensor to change.
The changing gap causes the magnetic field near the sensor to
change.
Due to the changing magnetic field, the voltage from the sensor
changes.
The ECM receives the voltage signal and detects the fluctuation of
the engine revolution.
ECM receives the signals as shown in the figure.

IGNITION SIGNAL
DescriptionINFOID:0000000003856848
The ignition signal from the ECM is sent to and amplified by the power transistor. The power transistor turns
ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil
secondary circuit.

CAUTION:
 Every time the vehicle is lifted up, maintain the complete vehicle curb condition.
 Since the vehicle's center of gravity changes when removing main parts on the front side (engine,
transmission, suspension etc.), support a jack up point on the rear side garage jack with a mission
jack or equivalent.
 Since the vehicle's center of gravity changes when removing main parts on the rear side (rear axle,
suspension, etc.), support a jack up point on the front side garage jack with a mission jack or equiv-
alent.
 Be careful not to smash or do not do anything that would affect piping parts.
Garage Jack and Safety Stand and 2-Pole LiftINFOID:0000000003852789
WARNING:
 Park the vehicle on a level surface when using the jack. Make sure to avoid damaging pipes, tubes,
etc. under the vehicle.
 Never get under the vehicle while it is supported only by the jack. Always use safety stands when
you have to get under the vehicle.
 Place wheel chocks at both front and back of the wheels on the ground.
 When lifting the vehicle, open the lift arms as wide as possible and ensure that the front and rear of
the vehicle are well balanced.
 When setting the lift arm, do not allow the arm to contact the brake tubes, brake cable, fuel lines and

 Do not apply excessive shock to the control unit by dropping or hit-
ting it.
 Be careful to prevent condensation in the control unit due to rapid
temperature changes and do not let water or rain get on it. If water
is found in the control unit, dry it fully and then install it in the vehi-
cle.
 Be careful not to let oil to get on the control unit connector.
 Avoid cleaning the control unit with volatile oil.
 Do not disassemble the control unit, and do not remove the upper
and lower covers.
 When using a DMM, be careful not to let test probes get close to
each other to prevent the power transistor in the control unit from
damaging battery voltage because of short circuiting.
 When checking input and output signals of the control unit, use the
specified check adapter.
Intermittent IncidentINFOID:0000000003852795
DESCRIPTION
Sometimes the symptom is not present when the vehicle is brought in for service. If possible, re-create the
conditions present at the time of the incident. Doing so may help avoid a No Trouble Found Diagnosis. The fol-
lowing section illustrates ways to simulate the conditions/environment under which the owner experiences an
electrical incident.
The section is broken into the six following topics: Vehicle vibration
 Heat sensitive
 Freezing
 Water intrusion
 Electrical load
 Cold or hot start up
Get a thorough description of the incident from the customer. It is important for simulating the conditions of the
problem.
VEHICLE VIBRATION
The problem may occur or become worse while driving on a rough road or when engine is vibrating (idle with
A/C on). In such a case, you will want to check for a vibration related condition. Refer to the following illustra-
tion.
