2. Check procedure
Yes
Reconnect the sensor connector.
No
Is the sensor connector
connected correctly in accordance with
a color?
Yes
No
Sensor Replace
Sensor resistance value : 20°C - 242kohm
30°C - 166kohm
35°C - 138kohm
40°C - 115kohm
Exchange the Outdoor PBA.
No
Yes
Is the sensor resistance
value 200kohm±3% at the room temperature
of 25°C?
Below 0.5V or Over 4.5V?
Yes
Connect the sensor to PBA connector
supply power and measure the voltage of
sensor in the connector.
Micom error or connector check.
Exchange the Outdoor PBA.
