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

  1. Start the engine and wait for 10 seconds or more.
  2. Check the first trip DTC.

Is "P0712" detected?

YES >> Go to TM "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.CHECK CIRCUIT BETWEEN TCM AND CVT UNIT

  1. Turn ignition switch OFF.
  2. Disconnect TCM connector and CVT unit connector.
  3. Check continuity between TCM harness connector terminal and ground. 

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".
