Input/Turbine Speed Sensor Inspection

INPUT/TURBINE SPEED SENSOR INSPECTION [AY6A-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 fresh-air duct and air cleaner component as a single unit. Service and Repair

3. Remove the TCM. Service and Repair

4. Measure the no continuity between coupler component terminals B12 and GND, B13 and GND.

- If there is any malfunction, inspect the coupler component for continuity. Testing and Inspection
- If the coupler component is normal, perform an off-vehicle inspection of input/turbine speed sensor.

5. Measure the continuity between coupler component terminals B12 and B13.

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.

NOTE:
- Inspect with a tester that can indicate more than 10 megohms and confirm that the value is more than 1 megohm.

2. Measure the current while waving a magnet back and forth over the top of the input/turbine speed sensor (less than 5 mm {0.2 in}).

- If there is any malfunction, replace the input/turbine speed sensor.
