TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR INSPECTION

BHE051319200W04

  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 engine cover. (See ENGINE COVER REMOVAL/INSTALLATION.)

2. Remove the battery cover.

3. Disconnect the negative battery cable.

4. Remove the catalytic converter.

(See EXHAUST SYSTEM REMOVAL/INSTALLATION.)

5. Remove the insulator.

6. Disconnect the solenoid valve connector.

7. Measure resistance between the terminals C and D.

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

100 {212} | 0.181-0.200
120 {248} | 0.112-0.123
130 {266} | 0.089-0.099

8. Connect the solenoid valve connector.

9. Install the insulator.

  Tightening torque
  8-11 N·m {82-112 kgf·cm, 72-97 in·lbf}

10. Install the catalytic converter.

(See EXHAUST SYSTEM REMOVAL/INSTALLATION.)

11. Connect the negative battery cable.

12. Install the battery cover.

13. Install the engine cover. (See ENGINE COVER REMOVAL/INSTALLATION.)

## 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.)

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

3. Measure the resistance between the TFT sensor terminals.

  • If there is any malfunction, replace the TFT sensor. (See TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION.)
