Code No. P0712: Malfunction of CVT Fluid Temperature Sensor (low input)
 
 
 
 
DIAGNOSTIC FUNCTION
CVT-ECU conducts fault detection by monitoring the terminal voltage of the CVT fluid temperature sensor.
 
 
JUDGEMENT CRITERIA
CVT-ECU detects the fluid temperature 180°C or more for 5 seconds.
 
 
PROBABLE CAUSES
  • Malfunction of CVT fluid temperature sensor
  • Damaged wiring harness and connectors
  • Malfunction of CVT-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Check for short to earth in SPWR line between the CVT assembly connector and the CVT-ECU connector
Is the check result normal?
Go to Step 2.
Repair the connector(s) or the wiring harness.
 
STEP 2. CVT fluid temperature sensor check
Refer to .
Is the check result normal?
Go to Step 3.
Replace the CVT fluid temperature sensor (valve body harness) (Refer to ).
 
STEP 3. Symptom recheck after erasing diagnosis code
Is the diagnosis code set?
Replace the CVT-ECU.
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
