(a)Remove the engine coolant temperature sensor.
(b)Measure the resistance between the terminals.
Resistance:
2.32 to 2.59 k at 20

NOTICE:
In case of checking the engine coolant temperature sensor
in the water, be careful not to allow water to go into the ter-
minals. After checking, dry the sensor.
HINT:
Alternate procedure: Connect an ohmmeter to the installed en-
gine coolant temperature sensor and read the resistance. Use
an infrared thermometer to measure the engine temperature in
the immediate vicinity of the sensor. Compare these values to
the resistance/temperature graph. Change the engine temper-
ature (warm up or allow to cool down) and repeat the test.

NOISE OCCURS
INSPECTION PROCEDURE
1 CHECK OF SPEAKER INSTALLATION
(a) Check the speaker installation condition.
(1) Check that each speaker is securely installed.
Standard: Malfunction disappears.
HINT:
The radio is equipped with the noise prevention system that works against only the excessively large noise,
thereby excessively large noise do not occur in the radio. If large noise occurs, check whether or not the earth
on the antenna installation part and the proper noise±prevention equipment are all installed, and whether
or not the improper wiring is held.
Condition in which noise occursNoise type
Depressing the acceleration pedal increases noise, and stopping the engine
erases the noise immediately.Alternator noise
Noise occurs during the A/C or the heater operation.Blower motor noise
Rapid acceleration during the drive on the unpaved road or after the IG
switch is turned ON makes noise.Fuel pump noise
Pressing and then releasing the horn switch, and keeping pressing the horn
switch makes noise.Horn noise
Stopping the engine erases the small noise that has been heard.Ignition noise
Noise occurs in turn with the blink of the turn signal flash.Flasher noise
Noise occurs during the window washer operation.Washer noise
Noise occurs during the engine running, and it continues to occur after the
engine is stopped.Water temperature sensor noise
Noise occurs during the wiper operation.Wiper noise
Noise occurs when the brake pedal is depressed.Stop light switch noise
Others.Static electricity on the vehicle
HINT:

Identify the condition under which the noise occurs, and check the noise filter on the related part.

Make sure first that there is no noise from outside. Failing to do so makes the noise occurrence source
detection impossible and leads to misunderstanding.

The noise should be removed in descending order of loudness.
NG INSTALL IT PROPERLY
