| Description |
| 1. |
The photo sensor is located at the center of defrost nozzle. |
| 2. |
The photo sensor contains a photovoltaic (sensitive to
sunlight) diode. The solar radiation received by its light receiving
portion, generates an electromotive force in proportion to the amount of
radiation received which is transferred to the automatic temperature
control module so that the solar radiation compensation will be
performed. |
Inspection 1. Ignition "OFF". 2. Disconnect evaporator temperature sensor. 3. Using the multi-tester, Measure resistance between terminal "1" and "2" of evaporator temperature sensor.
Inspection 1. Ignition "ON" 2. Using the scan tool. 3. Emit intensive light toward photo sensor using a lamp, and check the output voltage change.
Inspection 1. Ignition "OFF" 2. Disconnect the connector of temperature control actuator. 3. Verify that the temperature control actuator operates to the hot position when connecting 12V to the terminal 3 and grounding terminal 7. Verify that the temperature control actuator operates to the cool position when connecting in the rev
Inspection 1. Ignition "OFF". 2. Disconnect the intake actuator connector. 3. Verify that the actuator operates to the recirculation position when connecting 12V to the terminal 3 and grounding terminal 7. 4. Verify that the intake actuator operates to the fresh position when connecting in the reverse.
