AUTOMATIC TRANSAXLE
TRANSAXLE FLUID TEMPERATURE (TFT)
SENSOR INSPECTION
On-Vehicle Inspection
1. Disconnect the negative battery cable.
2. Remove the fresh-air duct and air cleaner
component. (See Section F1.)
Caution
• Water or foreign objects entering the
connector can cause poor connection or
corrosion. Be sure not to drop water or
foreign objects on the connector when
disconnecting it.
3. Disconnect the transaxle connector.
4. Measure the resistance between the terminals E
and H.
• If it is out of specification, perform the
off-vehicle inspection of TFT sensor. (See
K2-35 TRANSAXLE FLUID TEMPERATURE
(TFT) SENSOR REMOVAL/INSTALLATION.)

6. Install the air cleaner component and fresh-air
duct. (See Section F1.)
7. Connect the negative battery cable.
Off-Vehicle Inspection
Warning
• When the transaxle and ATF are hot, they
can badly burn. Turn off the engine and
wait until they are cool before replacing
ATF.
1. Remove the control valve body. (See K2-46
CONTROL VALVE BODY REMOVAL, On-Vehicle
Removal.)
2. Remove the transaxle connector.
3. Remove the TFT sensor from the strainer, and
connect it to the transaxle connector.
4. Place the TFT sensor and a thermometer in ATF
as shown, and heat the ATF gradually.
5. Measure the resistance between the terminals of
the TFT sensor.
• If not as specified, replace the TFT sensor.
