DTC DETECTION LOGIC
DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P0720 | Output Speed Sensor Circuit | The output speed sensor value is less than
150 rpm continuously for 10 seconds or more
under the following diagnosis conditions: - Diagnosis conditions - Selector lever: "D", "L" or "R" position - Auxiliary gearbox shifting is not in progress. - When the "D" position switch, "L" position switch or "R" position switch is ON, the output speed has not experienced 250 rpm or more. - After shifting the selector lever, the input speed has experienced less than 300 rpm. - Secondary pulley speed: 1,500 rpm or more - TCM power supply voltage: More than 11 V |
- Harness or connector
(Output speed sensor circuit is open or
shorted) - Output speed sensor |
The output speed sensor value is 90 rpm or
less continuously for 500 msec or more under
the following diagnosis conditions: - Diagnosis conditions - 10-msec-ago output speed: 730 rpm or more - TCM power supply voltage: More than 11 V |
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.
2.CHECK DTC DETECTION
Selector lever : "D" position Vehicle speed : 55 km/h (34 MPH) or more
Is "P0720" detected?
YES >> Go to TM "Diagnosis Procedure".
NO >> INSPECTION END
1.CHECK OUTPUT SPEED SENSOR POWER CIRCUIT
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)
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)
Check continuity between output 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
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI "Intermittent Incident".
NO >> Replace output speed sensor. Refer to TM "Removal and Installation".
6.CHECK CIRCUIT BETWEEN IPDM E/R AND OUTPUT SPEED SENSOR (PART 1)
Is the check result normal?
YES >> GO TO 7.
NO >> Repair or replace malfunctioning parts.
7.CHECK CIRCUIT BETWEEN IPDM E/R AND OUTPUT SPEED SENSOR (PART 2)
Check continuity between IPDM E/R harness connector terminal and ground.
Is the check result normal?
YES >> GO TO 8.
NO >> Repair or replace malfunctioning parts.
8.DETECT MALFUNCTIONING ITEMS
Check the following items:
Is the check result normal?
YES >> Check intermittent incident. Refer to GI "Intermittent Incident".
NO >> Repair or replace malfunctioning parts.

YES >> Trunk room lamp switch is OK.
NO >> Refer to DLK "Diagnosis ...
ECM Branch line circuit
Diagnosis Procedure
1.CHECK CONNECTOR
1. Turn the ignition switch OFF.
2. Disconnect the battery cable from the negative terminal.
3. Check the terminals and connectors of the ECM for damage, bend and loose
connection (unit side and
connector side).
Is the inspection result normal?
YES &g ...
