Kia Carnival (2009+). Manual — part 542

2009 > G 2.7 DOHC >

COMPONENT LOCATION

2009 > G 2.7 DOHC >

DESCRIPTION

The evaporator temperature sensor will detect the evaporator core temperature and interrupt compressor relay power
in order to prevent evaporator freezing by excessive cooling.

2009 > G 2.7 DOHC >

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.
