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

BME051719200205

  Caution

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

## On-Vehicle Inspection

1. Disconnect the negative battery cable.

2. Remove the battery, battery box and battery tray. (See BATTERY REMOVAL/INSTALLATION [L3, AJ].)

3. Remove the air cleaner cover. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3].)

4. Disconnect the transaxle connector.

5. Measure the resistance between transaxle connector terminals E and H.

  • If there is any malfunction, perform the TFT sensor off-vehicle inspection. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [FN4A-EL].)

ATF temperature (°C {°F}) | Resistance (kilohm)
--- | ---
-20 {-4} | 236-324
0 {32} | 84.3-110
20 {68} | 33.5-42.0
40 {104} | 14.7-17.9
60 {140} | 7.08-8.17
80 {176} | 3.61-4.15
100 {212} | 1.96-2.24
120 {248} | 1.13-1.28
130 {266} | 0.87-0.98

6. Install the air cleaner cover. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [L3].)

7. 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 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 terminals of the TFT sensor.

  • If there is any malfunction, replace the TFT sensor. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [FN4A-EL].)
