TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR INSPECTION[FN4A-EL]

id0517a1801000


On-Vehicle Inspection

1.  Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION[ZJ, ZY, Z6].) (See BATTERY REMOVAL/INSTALLATION[LF, L3].)

2.  Disconnect the negative battery cable.

3.  Remove the under cover.

Caution
•  Water or foreign material entering the connector can cause a poor connection or corrosion. Be sure not to drop water or foreign material on the connector when disconnecting it.

4.  Disconnect the transaxle connector.

Off-Vehicle Inspection

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

1.  Remove the control valve body. (See CONTROL VALVE BODY REMOVAL[FN4A-EL].)

2.  Remove the coupler component.

3.  Place the TFT sensor and a thermometer in ATF as shown in the figure, and heat the ATF gradually.

4.  Measure the resistance between the terminals of the TFT sensor.
