DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P0712 | Transmission Fluid Temperature Sensor A Circuit Low | The CVT fluid temperature identified by the
TCM is 180C (356F) or more continuously
for 5 seconds or more under the following diagnosis
conditions: - Diagnosis conditions - Ignition switch: ON - TCM power supply voltage: More than 11 V |
- Harness or connector
(CVT fluid temperature sensor circuit is
shorted to ground) - CVT fluid temperature sensor |
DTC CONFIRMATION PROCEDURE
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.PERFORM DTC CONFIRMATION PROCEDURE
Is "P0712" detected?
YES >> Go to TM "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK CIRCUIT BETWEEN TCM AND CVT UNIT
Is the inspection result normal?
YES >> GO TO 2.
NO >> Repair or replace malfunctioning part.
2.CHECK CVT FLUID TEMPERATURE SENSOR
Check CVT fluid temperature sensor. Refer to TM"Component Inspection (CVT Fluid Temperature Sensor)".
Is the inspection result normal?
YES >> Check intermittent incident. Refer to GI"Intermittent Incident".
NO >> Repair or replace malfunctioning parts.
Component Inspection (CVT Fluid Temperature Sensor)
1.CHECK CVT FLUID TEMPERATURE SENSOR
Check resistance between CVT unit connector terminals.
Is the inspection result normal?
YES >> INSPECTION END
NO >> There is a malfunction of CVT fluid temperature sensor. Replace transaxle assembly. Refer to TM "Removal and Installation".
