TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR INSPECTION [SJ6A-EL]

id051311710300

  Caution
  • Water or foreign material entering the connector can cause poor connections or corrosion. Be sure that water or foreign material do not enter the connector when disconnecting it.

On-Vehicle Inspection

1. Remove the battery cover.

2. Disconnect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

3. Disconnect the coupler component connector.

  • If there is any malfunction, perform the off-vehicle inspection for TFT sensor. (See Off-Vehicle Inspection.)

Transmission fluid temperature (TFT) sensor

ATF temperature (°C {°F}) | Resistance (kilohm)
--- | ---
10 {50} | 6.445
25 {77} | 3.5
110 {230} | 0.247

5. Connect the coupler component connector.

6. Connect the negative battery cable. (See BATTERY REMOVAL/INSTALLATION [L8, LF].)

7. Install the battery cover.

Off-Vehicle Inspection

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

1. Remove the TFT sensor. (See TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION [SJ6A-EL].)

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