DTC Description
INFOID:0000000010622848
DTC DETECTION LOGIC
POSSIBLE CAUSE
• Harness or connector (Output speed sensor circuit is open or shorted)
• Output speed sensor
FAIL-SAFE
• Start is slow
• Acceleration is slow

DTC CONFIRMATION PROCEDURE
CAUTION:
Be careful of the driving speed.
1.
PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at
least 10 seconds, then perform the next test.
>> GO TO 2.

Diagnosis Procedure
INFOID:0000000010622849
1.
CHECK OUTPUT SPEED SENSOR POWER CIRCUIT
1.
Turn ignition switch OFF.
2.
Disconnect output speed sensor connector.
3.
Turn ignition switch ON.
4.
Check voltage between output speed sensor harness connector terminal and ground.
Is the inspection result normal?
YES
>> GO TO 2.
NO
>> GO TO 6.
2.
CHECK OUTPUT SPEED SENSOR GROUND CIRCUIT
Check continuity between output 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 OUTPUT SPEED SENSOR AND TCM (PART 1)
1.
Turn ignition switch OFF.
2.
Disconnect TCM connector.
3.
Check continuity between output speed sensor harness connector terminal and TCM harness connector
terminal.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Repair or replace malfunctioning parts.
4.
CHECK CIRCUIT BETWEEN OUTPUT SPEED SENSOR AND TCM (PART 2)
