Caution

• Water or foreign material entering the connector can cause a poor connection or corrosion. Be 

sure not to allow water or foreign material on the connector when disconnecting.

• Do not damage the terminals.

1. Disconnect the negative battery cable.
2. Remove the air cleaner component. (See 01-13-5 INTAKE AIR SYSTEM REMOVAL/INSTALLATION[L3 WITH 

TC].)

3. Remove the TCM. (See 05-17-25 TCM REMOVAL/INSTALLATION[AW6A-EL, AW6AX-EL].)
4. Verify that there is no continuity between the 

coupler component terminals B12 and GND or 
B13 and GND.

• If there is any malfunction, inspect the coupler 

component.

• If the coupler component is normal, perform 

an off-vehicle inspection of input/turbine 
speed sensor. (See05-17-16 Off-Vehicle 
Inspection.)

Note

• Inspect with a tester that can indicate more 

than 10 megohms and confirm that the 
value is more than 1 megohm.

5. Verify that there is continuity between coupler 

component terminals B12 and B13.

• If there is any malfunction, inspect the coupler 

component.

• If the coupler component is normal, replace 

the input/turbine speed sensor. (See 05-17-17 
INPUT/TURBINE SPEED SENSOR 
REMOVAL/INSTALLATION[AW6A-EL, 
AW6AX-EL].)

6. Install the TCM. (See 05-17-25 TCM REMOVAL/

INSTALLATION[AW6A-EL, AW6AX-EL].)

7. Install the air cleaner component. (See 01-13-5

8. Remove the input/turbine speed sensor. (See 05-

17-17 INPUT/TURBINE SPEED SENSOR 
REMOVAL/INSTALLATION[AW6A-EL, AW6AX-
EL].)

9. Connect the input/turbine speed sensor terminal 

2 to the battery positive terminal, connect the 
battery negative terminal to input/turbine speed 
sensor terminal 1 through an ammeter set to a 
resistance of 100 ohm.

10. Measure the current while waving a magnet back 

and forth over the top of the input/turbine speed 
sensor (less than 5 mm {0.197 in}).

• If there is any malfunction, replace the input/

turbine speed sensor. (See 05-17-17 INPUT/
TURBINE SPEED SENSOR REMOVAL/
