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




PROBABLE CAUSES




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

Q. 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


Q. 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 .

Q. 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 .

Q. 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


Q. Is the diagnosis code set?

Replace the CVT-ECU.
Intermittent malfunction.
