Input/Turbine Speed Sensor Inspection [AW6A-EL]

INPUT/TURBINE SPEED SENSOR INSPECTION [AW6A-EL]

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 air cleaner component. Service and Repair

3. Remove the TCM. TCM Removal/Installation [AW6A-EL]

4. Verify that there is no continuity between the coupler component terminals B12 and GND or B13 and GND.











- If there is continuity, 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 no continuity, inspect the coupler component.
- If the coupler component is normal, replace the input/turbine speed sensor. Input/Turbine Speed Sensor Removal/Installation [AW6A-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.






2. 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. Input/Turbine Speed Sensor Removal/Installation [AW6A-EL]
