INSPECTION
1. INSPECT AMBIENT TEMPERATURE SENSOR
(a) Measure the resistance of the sensor.
Standard resistance:
NOTICE:
-
Touching the sensor even slightly may change the resistance value. Hold the connector of the sensor.
-
When measuring the resistance, the sensor temperature must be the same as the ambient temperature.
HINT: As the temperature increases, the resistance decreases (see the graph).
If the result is not as specified, replace the ambient temperature sensor.
