id051723801400

On-Vehicle Inspection

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.

4. Verify that there is no continuity between the 

coupler component terminals B19 and GND or 
B20 and GND.

• If there is any malfunction, inspect the coupler 

component.

• If the coupler component is normal, replace 

the ATX. (See05-17-29 AUTOMATIC 
TRANSAXLE REMOVAL/
INSTALLATION[AW6A-EL, AW6AX-EL].)

Note

• Inspect with a tester that can indicatemore 

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

5. Verify that there is continuity between coupler 

component terminals B19 and B20.

• If there is any malfunction, inspect the coupler 

component.

• If the coupler component is normal, replace 

the ATX. (See05-17-29 AUTOMATIC 
TRANSAXLE REMOVAL/
INSTALLATION[AW6A-EL, AW6AX-EL].)

6. Install the TCM. (See05-17-25 TCM REMOVAL/

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

7. Install the air cleaner component. (See01-13-5 

INTAKE AIR SYSTEM REMOVAL/
INSTALLATION[L3 WITH TC].)

8. Connect the negative battery cable.

Off-Vehicle Inspection

Warning

• A hot transaxle and ATF can cause severe burns. Turn off the engine and wait until they are cool 

before replacing the ATF.

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 VSS. (See05-17-19 VEHICLE SPEED SENSOR (VSS) REMOVAL/INSTALLATION[AW6A-EL, 

AW6AX-EL].)

3. Connect the VSS terminal 2 to the battery positive 

terminal, connect the battery negative terminal to 
VSS terminal 1 through an ammeter set to a 
resistance of 100 ohm.

4. Measure the current while waving a magnet back 

and forth over the top of the VSS (less than 5 
mm {0.197 in}).

• If there is any malfunction, replace the VSS. 

(See05-17-19 VEHICLE SPEED SENSOR 
(VSS) REMOVAL/INSTALLATION[AW6A-EL, 
AW6AX-EL].)

VEHICLE SPEED SENSOR (VSS) REMOVAL/INSTALLATION[AW6A-EL, AW6AX-EL]

id051723806100

Caution

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

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

• If foreign materials are stuck to the VSS, disturbance by magnetic flux can cause sensor output to 

be abnormal and thereby negatively affect control. Make sure that foreign materials such as iron 
filings are not stuck to the VSS during installation.

1. Remove the automatic transaxle. (See 05-17-29 AUTOMATIC TRANSAXLE REMOVAL/

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

2. Remove the VSS. (See Automatic Transaxle and Transfer Workshop Manual AW6A-EL, AW6AX-EL)
