A/c Compressor Controls (Full Auto): Overview Hyundai Tucson I

Scheme 26

DESCRIPTION

The photo sensor is located in the center of defrost nozzle. In response to the photo intensity level in the vehicle, the sensor will send signals to control module to control the blower level and discharge temperature.

IDENTIFYING PHOTO SENSOR CIRCUITS

Scheme 29

1. The water sensor, located at the heater core.
2. It will detect water temperature, the sensor will send signal to control module.

Scheme 30

1. The AQS sensor, located at the center support in front of the engine radiator, detects hazardous elements in ambient air and provides output signals to the control module.
2. Detectable cases Diesel engine exhaust gases: NO, NO 2 , SO 2 Gasoline/LPG engine exhaust gases: CxHy, CO
3. Electrical specification Operating voltage: DC 9 ~ 16V Rated voltage: DC 12V Consumed current: less than 200mA Operating temperature: -30 ~ 105°C Storage temperature: -40 ~ 125°C

1. The air temperature sensor, located at the front of the engine radiator, detects ambient air temperature. It is a negative type thermistor; resistance will increase with lower temperatures, and decrease with higher temperatures.
2. The sensor output will be used for discharge temperature sensor, sensor fail-safe, temperature regulation door control, blower motor level control, mix mode control and in-car humidity control. R25°C: 30Kohm; +/- 3% B(0/25): 3754K +/- 2% Operation Temp. range: -30°C ~ 80°C

Scheme 31

1. The in car sensor, located at the heater control module.
2. It will detect interior temperature, the sensor will send signal to control module. IDENTIFYING IN CAR SENSOR CIRCUITS AT HEATER CONTROL MODULE Pin No. B1 B9 Circuit Sensor IN Sensor OUT

Scheme 33

1. The evaporator temp. sensor, located at the evaporator core.
2. It will detect evaporator temperature, the sensor will send signal to control module.

Scheme 34

1. The humidity sensor, located at the heater control module.
2. It will detect interior humidity, the sensor will send signal to control module. IDENTIFYING HUMIDITY SENSOR CIRCUITS AT HEATER CONTROL MODULE Pin No. A7 B14 Circuit Sensor IN Sensor OUT
