Code No. P0713: Malfunction of CVT Fluid Temperature Sensor (high input)




DIAGNOSTIC FUNCTION


CVT-ECU conducts fault detection by monitoring the terminal voltage of the CVT fluid temperature sensor.

JUDGEMENT CRITERIA


The CVT-ECU detects the fluid temperature -40°C or less for 5 seconds when the vehicle speed is 10km/h or more.

PROBABLE CAUSES




DIAGNOSIS PROCEDURE


STEP 1. Check for open circuit in SPWR and SGND line between the CVT assembly connector and the CVT-ECU connector


Q. Is the check result normal?

Go to Step 2
Repair the connector(s) or the wiring harness.

STEP 2. Voltage measurement at CVT-ECU connector (SPWR terminal)


(1)Connect the CVT assembly connector and the CVT-ECU connector.
(2)Turn the ignition switch to the "LOCK" (OFF) position.
(3)Measure the CVT-ECU connector side by backprobing.
(4)Measure the voltage between the CVT-ECU connector SPWR terminal and body earth.
OK: 0 V

Q. Is the check result normal?

Go to Step 3
Repair the connector(s) or the wiring harness.

STEP 3. CVT fluid temperature sensor check


Refer to .

Q. Is the check result normal?

Go to Step 4
Replace the CVT fluid temperature sensor (valve body harness). (Refer to .).

STEP 4. Symptom recheck after erasing diagnosis code


Q. Is the diagnosis code set?

Replace the CVT-ECU.
Intermittent malfunction.
