INPUT/TURBINE SPEED SENSOR INSPECTION [AW6A-EL, AW6AX-EL]

id051723801200

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 terminal.

1.  Disconnect the negative battery cable.

2.  Remove the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

3.  Remove the TCM. (See 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. (SeeOff-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 INPUT/TURBINE SPEED SENSOR REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)

6.  Install the TCM. (See TCM REMOVAL/INSTALLATION [AW6A-EL, AW6AX-EL].)

7.  Install the air cleaner component. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [MZI-3.7].)

8.  Connect the negative battery cable.

9.  Perform the neutral position learning. (See NEUTRAL POSITION LEARNING [AW6A-EL, AW6AX-EL])

Off-Vehicle Inspection

1.  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.
