TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR INSPECTION [AY6A-EL, AY6AX-EL]

id0517k3298100

  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.
  • Do not damage the terminals.

On-Vehicle Inspection

1. Disconnect the negative battery cable.

2. Remove the fresh-air duct and air cleaner component as a single unit. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

3. Remove the TCM. (See TCM REMOVAL/INSTALLATION [AY6A-EL, AY6AX-EL].)

4. Measure the resistance between coupler component terminals B7 and B8.

  • If there is any malfunction, inspect the coupler component for continuity. (See COUPLER COMPONENT INSPECTION [AY6A-EL, AY6AX-EL].)
  • If coupler component has no malfunction, perform the “Off-Vehicle Inspection“. (See Off-Vehicle Inspection.)

TFT sensor specification

ATF temperature (°C {°F}) | Resistance (kilohm)
--- | ---
10 {50} | 5.62—7.31
25 {77} | Approx. 3.5
110 {230} | 0.22—0.27

Off-Vehicle Inspection

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

  Warning
  • A hot ATF and beaker can cause severe burns. Do not touch them.

2. Measure the resistance between coupler component terminals B7 and B8.
