SENSOR
INSPECTION
1. REMOVE EVAPORATOR TEMPERATURE SENSOR
(a) Remove the blower unit (See page AC-37).
(b) Remove evaporator temperature sensor.
(1) Disconnect the connector.
(2) Pull out the sensor.
2. INSPECT EVAPORATOR TEMPERATURE SENSOR
Inspect evaporator temperature sensor resistance.
(1) Place the sensor in cold water, and while changing
the temperature of the water, measure resistance at
the connector and at the same time, measure tem-
perature of the water with a thermometer.
(2) Compare the 2 readings on the chart.
If resistance value is not as specified, replace the sensor.
3. INSTALL EVAPORATOR TEMPERATURE SENSOR
(a) Install the evaporator temperature sensor.
(1) Install the sensor.
(2) Connect the connector.
(b) Install the blower unit. (See page AC-41)
