TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR INSPECTION [LA4AX-EL (CD4E)]

Caution

• Liquid or foreign material penetrating the TFT sensor connector can cause a poor connection or corrosion. Be sure not to spill liquid or foreign material on the connector when disconnecting it.

1. Disconnect the negative battery cable.

2. Remove the battery and battery tray. (See BATTERY REMOVAL/INSTALLATION [YF (2.0L Zetec)].) (See BATTERY REMOVAL/INSTALLATION [L3, AJ (3.0L Duratec)].)

3. Disconnect the crankcase vent hose and MAF sensor connector.

4. Remove the air hose and air cleaner cover.

5. Remove the air cleaner component.

6. Disconnect the transaxle connector.

7. Measure the resistance between terminals H and E.

• If not within the specification, replace the solenoid valve body component.
