Code No. P0966: Malfunction of Secondary Pressure Solenoid Valve (low input)

DIAGNOSTIC FUNCTION

If a predetermined current does not flow into the secondary pressure solenoid valve (short to earth), the CVT-ECU will determine the system is defective.

JUDGEMENT CRITERIA

The solenoid valve drive circuit remains short to earth for 0.48 seconds.

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. Check for short to earth in SCLS 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. Secondary pressure solenoid valve check

Refer to

Q. Is the check result normal?

	Go to Step 4

	Go to Step 3

STEP 3. Check for short to earth 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 4. Symptom recheck after erasing diagnosis code

Q. Is the diagnosis code set?

	Replace the CVT-ECU.

	Intermittent malfunction.
