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.

Tooth Contact Pattern Diagnosis and Remedy
Normal
High Contact
Pinion is positioned too far from the center of drive
bevel gear (1).
• Increase thickness of pinion (2) height adjusting
shim and position pinion closer to gear center.
• Adjust drive bevel gear backlash to specification.
Low Contact
Pinion is positioned too close to the center of drive
bevel gear (1).
• Decrease thickness of pinion (2) height adjusting
shim and position pinion farther from gear center.
• Adjust drive bevel gear backlash to specification.
If adjustment is impossible, replace differential carrier.
• Check seating of bevel gear or differential case. (Check bevel
gear for runout.)
• If adjustment is impossible, replace drive bevel gear and pinion
set or differential carrier.
Replace drive bevel gear and pinion set or differential case.
