Coupling Air Temperature Sensor InspectionS6RW0D3206007
CAUTION!
Do not heat up coupling air temperature
sensor more than 100 °C (212 °F). Otherwise,
coupling air temperature sensor will be
damaged.

• Blow hot air to temperature sensing part (2) of
coupling air temperature sensor (3) using hot air drier
(4) and measure resistance between sensor terminals
while heating air gradually.
If measured resistance does not show such
characteristic as shown, replace air temperature
sensor.
Coupling Assembly InspectionS6RW0D3206008
• Check coupling assembly for oil leakage. If leakage
exists, replace it.
• Measure resistance between “a” terminal and “b”
terminal of coupling connector (1).
If measured resistance is out of specification, check
harness for open or short.
If OK, replace coupling assembly.
