>> GO TO 2.
2.CHECK DTC DETECTION
Selector lever : “D” position
Vehicle speed : 55 km/h (34 MPH) or more
Is “P0720” detected? YES >> Go to TM-181, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK OUTPUT SPEED SENSOR POWER CIRCUIT
Is the check result normal? YES >> GO TO 2.
NO >> GO TO 6.
2.CHECK OUTPUT SPEED SENSOR GROUND CIRCUIT
Check the continuity between output speed sensor harness connector terminal and ground.
Is the check result normal? YES >> GO TO 3.
NO >> Repair or replace malfunctioning parts.
3.CHECK CIRCUIT BETWEEN OUTPUT SPEED SENSOR AND TCM (PART 1)
Is the check result normal? YES >> GO TO 4.
NO >> Repair or replace malfunctioning parts.
4.CHECK CIRCUIT BETWEEN OUTPUT SPEED SENSOR AND TCM (PART 2)
Check continuity between output speed sensor harness connector terminal and ground.
Is the check result normal? YES >> GO TO 5.
NO >> Repair or replace malfunctioning parts.
5.Check tcm input signals
Is the check result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace output speed sensor. Refer to TM-270, "Exploded View".
6.DETECT MALFUNCTIONING ITEMS
Check the following items:
Is the check result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Repair or replace malfunctioning parts.
