Transaxle Fluid Temperature (Tft) Sensor Inspection [FS5 A EL]
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.
1. Perform the following procedures.
a. Remove the battery cover..
b. Disconnect the negative battery cable.
c. Remove the air cleaner component..
d. Disconnect the coupler component connector.
2. Measure the resistance between the coupler component terminals E and H.
If there is any malfunction, replace the TFT sensor..

Off-Vehicle Inspection
1. Place the TFT sensor and a thermometer in ATF as shown, and heat the ATF gradually.
WARNING:
A hot ATF and beaker can cause severe burns. Do not touch them.
2. Measure the resistance between the coupler component terminals E and H.
If there is any malfunction, replace the TFT sensor..
