1. Inspect Room Temperature Sensor.
A. Measure the sensor resistance.
Resistance Value at 775F
(255C)1700 +/± 85W
NOTE:
Even slightly touching the sensor
may change the resistance value.
Be sure to hold the connector of
the sensor.
When measuring, the sensor
temperature must be the same as
the ambient temperature.
HINT:
As the temperature increases, the
resistance decreases.

2. Inspect Ambient
Temperature Sensor.
A. Measure the sensor resistance
according to the selected graph
(specification).
Resistance Value at 775F
(255C)1700 +/± 85W
NOTE:
Even slightly touching the sensor
may change the resistance value.
Be sure to hold the connector of
the sensor.

3. Inspect Air Duct Sensor.
A. Measure the sensor resistance
according to the table and
graph (specification).
NOTE:
Even slightly touching the sensor
may change the resistance value.
Be sure to hold the connector of
the sensor.
When measuring, the sensor
temperature must be the same as
the ambient temperature.
HINT:
As the temperature increases, the
resistance decreases.
