DTC | Trouble diagnosis name | DTC detection condition | Possible causes |
P0712 | Transmission Fluid Temperature Sensor "A" Circuit Low | Under the following diagnosis
conditions, the A/T fluid temperature
identified by TCM is
180C (356F) or more continuously
for 5 seconds or more. - Diagnosis condition - Ignition switch: ON - TCM power supply voltage: 10 V <TCM power supply voltage <16 V |

DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn the 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 A/T UNIT
Is the check result normal?
YES >> GO TO 2.
NO >> Repair or replace malfunctioning part.
2.CHECK FLUID TEMPERATURE SENSOR
Check the fluid temperature sensor. Refer to TM, "Component Inspection (A/T Fluid Temperature Sensor)".
Is the check result normal?
YES >> Check intermittent incident. Refer to GI "Intermittent Incident".
NO >> Repair or replace the malfunctioning parts.
Component Inspection (A/T Fluid Temperature Sensor)
1.CHECK A/T FLUID TEMPERATURE SENSOR
Measure the resistance between the A/T unit connector terminals.
Is the check result normal?
YES >> INSPECTION END
NO >> There is a malfunction of the A/T fluid temperature sensor. Replace the transaxle assembly. Refer to TM, "Removal and Installation".
