TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR INSPECTION [FS5A-EL]

id051721801000

## On-Vehicle Inspection

1. Disconnect the negative battery cable.

2. Remove the air cleaner component. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L3].)

  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 (primary).

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 TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [FS5A-EL].)

Transaxle fluid temperature (TFT) sensor

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

5. Install the air cleaner component. (See INTAKE AIR SYSTEM REMOVAL/INSTALLATION [L8, LF, L3].)

6. 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. Disconnect the negative battery cable.

2. Remove the coupler component. (See PRIMARY CONTROL VALVE BODY REMOVAL [FS5A-EL].)

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

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

  • If not as specified, replace the TFT sensor. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [FS5A-EL].)
