Input/Turbine Speed Sensor Inspection




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

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.

2. Remove the air cleaner component. Service and Repair

3. Remove the TCM. Service and Repair

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.

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. Input/Turbine Speed Sensor Removal/Installation

6. Install the TCM. Service and Repair

7. Install the air cleaner component. Service and Repair

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.
