23 -AUTOMATIC TRANSMISSION > 23A-CVT > TROUBLESHOOTING<CVT><CVT> > DIAGNOSIS CODE PROCEDURES > CODE NO. P0967: SECONDARY PRESSURE SOLENOID MALFUNCTION
Code No. P0967: Malfunction of Secondary Pressure Solenoid Valve (high input)
 
 
 
 
DIAGNOSTIC FUNCTION
The CVT-ECU monitors the secondary pressure solenoid valve circuit for open or short to power supply.
 
 
JUDGEMENT CRITERIA
  • All the conditions listed below remain for 0.2 seconds.
    • The secondary pressure solenoid valve command current is 750 mA or more.
    • The secondary pressure solenoid valve current, which the CVT-ECU monitors, is 200 mA or less.
    • The solenoid valve drive circuit is not shorted to earth.
  • All the conditions listed below remain for 0.2 seconds.
    • The solenoid valve drive circuit is not shorted to earth.
    • The solenoid valve drive circuit system is defective.
 
 
PROBABLE CAUSES
  • Malfunction of the valve body assembly (Faulty secondary pressure solenoid valve)
  • Damaged wiring harness and connectors
  • Malfunction of CVT-ECU
 
 
DIAGNOSIS PROCEDURE
STEP 1. Voltage measurement at CVT-ECU connector (SCLS terminal)
(1) Disconnect the CVT-ECU connector, and measure at the wiring harness side.
(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between the CVT-ECU connector (SCLS terminal) and body earth.
OK: 0 V
Is the check result normal?
Go to Step 2.
NO : Repair the connector(s) or the wiring harness (SCLS line between the CVT assembly connector and the CVT-ECU connector).
 
STEP 2. Check for open circuit in SCLS line between the CVT assembly connector and the CVT-ECU connector
Is the check result normal?
Go to Step 3.
Repair the connector(s) or the wiring harness.
 
STEP 3. Secondary pressure solenoid valve check
Refer to .
Is the check result normal?
Go to Step 5.
Go to Step 4.
 
STEP 4. Check for open circuit in power supply line between the CVT assembly connector and the valve body harness connector (secondary pressure solenoid valve line)
Refer to .
Is the check result normal?
Replace the valve body assembly (Refer to ).
Replace the valve body harness (Refer to ).
 
STEP 5. 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 ).
