Kia Sportage: Photo Sensor | Ambient Sensor

Description and Operation

Description

1. The photo sensor is located at the right 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.

Repair procedures

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.

4. The voltage will rise with higher intensive light and reduce with lower intensive light.

Replacement

1. Disconnect the negative (-) battery terminal.

2. With the (-) driver, remove the photo sensor (A) from the center of defrost nozzle

3. Install in the reverse order of removal.

Ambient Sensor

Description and Operation

Description

1. The ambient temperature sensor is located at the front of the condenser and detects ambient air temperature. It is a negative type thermistor; resistance will increase with lower temperature, and decrease with higher temperatures.

2. The sensor output will be used for discharge temperature control, temperature regulation door control, blower motor level control, mix mode control and in-car humidity control.

NOTE

If the ambient temperature is below 1.0ºC (33.8ºF), the А/С compressor will be stopped.

The compressor will be operated by manual operating.

Repair procedures

Inspection

1. Ignition "OFF".

2. Disconnect ambient temperature sensor.

3. Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing of the ambient temperature.

1. Sensor Ground
2. Ambient Sensor Signal

Specification

4. If the measured resistance is not specification, substitute with a known-good ambient temperature sensor and check for proper operation.

5. If the problem is collected, replace the ambient temperature sensor.

Replacement

1. Disconnect the negative (-) battery terminal.

2. Disconnect the connector and then remove the ambient temperature sensor (A).

3. Installation is the reverse order of removal.
