Diagnosis Procedure

1. Turn ignition switch OFF.
2. Check ground connection M95. Refer to Ground Inspection in "CIRCUIT INSPECTION ".

   Is the inspection result normal? 

   YES: GO TO 2.

   NO: Repair or replace ground connection.

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