On-Vehicle Inspection
1. Disconnect the negative battery cable.
2. Remove the air cleaner component.

Caution:
^ Water or foreign objects entering the connector can cause a 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 terminals E and H.

5. Install the air cleaner component.
6. Connect the negative battery cable.

Off-Vehicle Inspection

Warning
^ A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool before changing the ATF.

1. Remove the control valve body.





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 resistance between the terminals of the TFT sensor.





^ If not as specified, replace the TFT sensor.
6. Disconnect the TFT sensor from the transaxle connector, and install it to the oil strainer.
7. Install the transaxle connector.
8. Install the control valve body.
