1. Remove the inside air temperature sensor and
measure the resistance between the sensor
connectors.
(approximately 2.2 KΩ at 25 °C) Replace the inside
air temperature sensor when the resistance value
is excessive low or high.
2. Replace the inside air temperature sensor for
outside the specified value and check the
followings for within the specified value;
3. Turn the ignition ON.
4. Measure the voltage between A13 and A16 terminal
of the AUTO temperature control connector.
(approximately 2.2 V at 25 °C)
5. Verify the open circuit of the wiring harness when
you can not measure the voltage value and replace
the AUTO temperature control when it's normal.
Ambient Sensor
Ambient sensor is a thermistor (NTC resistance) that
decreases its resistance when temperature up and
increases when temperature down and it detects
ambient air temperature. If there is open or short in
the sensors, 25 ° C (77 °F) will be substitute. The
sensor is located in the left back side of front bumper.
Inspection
When the ambient temperature sensor error displays,
check the followings;
1. Remove the ambient temperature sensor and then
measure the resistance between the sensor
connectors.
(approximately 2.2 KΩ at 25 °C) Replace the
ambient temperature sensor when the resistance
value is excessive low or high.
2. Replace the ambient temperature sensor for outside
the specified value and check the followings for
within the specified value;
3. Turn the ignition ON.
4. Measure the voltage between A13 and B8 terminal
of the AUTO temperature control connector.
(approximately 2.2 V at 25 °C)
5. Verify the open circuit of the wiring harness when
you can not measure the voltage value and replace
the AUTO temperature control when it's normal.
Coolant Temperature Sensor
Coolant temperature sensor is a thermistor that
decreases its resistance when temperature up and
increases when temperature down. It detects coolant
temperature to operate the blower speed at low when
the coolant temperature is less than 50 °C (122 ° F). If
the coolant temperature sensor is open or short, 100
° C (212 ° F) will be substitute.

AUTOMATIC CONTROL HVAC SYSTEM 7D-9
Inspection
When the coolant temperature sensor error displays,
check the followings;
1. Measure the resistance between the sensor
connectors. (approximately 2.2 KΩ at 25 °C)
2. Replace the coolant temperature sensor for outside
the specified value and check the followings for
within the specified value;
3. Turn the ignition ON.
4. Measure the voltage between A13 and B9 terminal
of the AUTO temperature control connector.
(approximately 2.2 V at 25 °C)
5. Verify the open circuit of the wiring harness when
you can not measure the voltage value and replace
the AUTO temperature control when it's normal.
Sun Sensor
Sun sensor is a photo diode that detects lights.
Resistance of the diode can be measured as current
by using voltmeter according to increasing sun loads.
If the sun sensor is error, no sun load will be substitute.
Photo Diode
It is used to the circuit converting the sun light loads
to the electric signals.
Inspection
When the sun sensor error displays, check the
followings;
1. Remove the sensor to place it under the sun light
and measure the current between the connector
terminals.
2. Place the sun sensor under the shadow place and
measure the current between the connector
terminals. If the value is lower than the value under
the sun light, it's normal.
3. Turn the ignition ON.
4. Measure the voltage between A13 and B10 terminal
of the AUTO temperature control connector. (Sun
light; 2.5 V, Shadow; 4.8 V)
5. Verify the open circuit of the wiring harness when
you can not measure the voltage value and replace
the AUTO temperature control when it's normal.
