2.Disconnect input speed sensor connector.
3.Turn ignition switch ON.
4.Check voltage between input speed sensor harness connector terminal and ground.





Is the inspection result normal?
YES - GO TO 2.
NO- GO TO 6.

2. CHECK INPUT SPEED SENSOR GROUND CIRCUIT

Check continuity between input speed sensor harness connector terminal and ground.





Is the inspection result normal?
YES - GO TO 3.
NO- Repair or replace malfunctioning parts.

3. CHECK CIRCUIT BETWEEN INPUT SPEED SENSOR AND TCM (PART 1)

1.Turn ignition switch OFF.
2.Disconnect TCM connector.

Is the inspection result normal?
YES - GO TO 4.
NO- Repair or replace malfunctioning parts.

4. CHECK CIRCUIT BETWEEN INPUT SPEED SENSOR AND TCM (PART 2)

Check continuity between input speed sensor harness connector terminal and ground.





Is the inspection result normal?
YES - GO TO 5.
NO- Repair or replace malfunctioning parts.

5. CHECK TCM INPUT SIGNALS

1.Connect all of disconnected connectors.
2.Lift the vehicle.
3.Start the engine.
4.Check frequency of input speed sensor.





Is the inspection result normal?
YES - Check intermittent incident. Refer to "Intermittent Incident" Intermittent Incident.
NO- Replace input speed sensor. Refer to "Removal and Installation" Removal And Installation.
