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
- Malfunction of CVT fluid temperature sensor
- Damaged wiring harness and connectors
- Malfunction of CVT-ECU
|
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.
