DTC detection condition | |
| P0966 |
PC SOLENOID B (Pressure Control Solenoid B Control Circuit Low) |
Diagnosis condition | TCM power supply voltage: More than 11 V |
| Signal | — | ||
| Threshold | TCM judges that solenoid valve circuit is shorted to ground | ||
| Diagnosis delay time | Maintained for 1 second | ||
POSSIBLE CAUSE
-
Harness or connector (Primary pressure solenoid valve circuit shorted to ground)
-
Primary pressure solenoid valve
FAIL-SAFE
-
Selector shock is large
-
Start is slow
-
Acceleration is slow
-
Lock-up is not performed
PREPARATION BEFORE WORK
If another "DTC CONFIRMATION PROCEDURE" occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>>
GO TO 2.
CHECK DTC DETECTION
-
Start the engine and wait for 5 seconds or more.
-
Check the first trip DTC.
Is “P0966” detected?
YES>>Go to Diagnosis Procedure.
NO-1>>To check malfunction symptom before repair: Refer to Intermittent Incident.
NO-2>>Confirmation after repair: INSPECTION END
CHECK CIRCUIT BETWEEN TCM AND CVT UNIT
-
Turn ignition switch OFF.
-
Disconnect TCM connector and CVT unit connector.
-
Check continuity between TCM harness connector terminal and ground.
TCM — Continuity Connector Terminal F25 40 Ground Not existed
Is the inspection result normal?
YES>>GO TO 2.
NO>>Repair or replace damaged parts.
CHECK CIRCUIT BETWEEN CUT UNIT AND GROUND
Check resistance between CVT unit harness connector terminal and ground.
| CVT unit | — | Condition | Resistance | |
|---|---|---|---|---|
| Connector | Terminal | |||
| F210 | 2 | Ground | CVT fluid temperature: 20°C (68°F) | 5.5 – 7.0 Ω |
| CVT fluid temperature: 50°C (122°F) | 6.0 – 8.0 Ω | |||
| CVT fluid temperature: 80°C (176°F) | 6.5 – 8.5 Ω | |||
Is the inspection result normal?
YES>>Check intermittent incident. Refer to Intermittent Incident.
NO>>GO TO 3.
CHECK CIRCUIT BETWEEN CVT UNIT AND CONTROL VALVE
-
Disconnect control valve connector. Refer to Removal and Installation.
-
Check continuity between CVT unit harness connector terminal and ground.
CVT unit — Continuity Connector Terminal F210 2 Ground Not existed
Is the inspection result normal?
YES>>GO TO 4.
NO>>Replace terminal cord assembly. Refer to Removal and Installation.
CHECK CIRCUIT BETWEEN CONTROL VALVE AND GROUND
Check resistance between control valve harness connector terminal and ground.
| Control valve | — | Condition | Resistance |
|---|---|---|---|
| Terminal | |||
| 9 | Ground | CVT fluid temperature: 20°C (68°F) | 5.5 – 7.0 Ω |
| CVT fluid temperature: 50°C (122°F) | 6.0 – 8.0 Ω | ||
| CVT fluid temperature: 80°C (176°F) | 6.5 – 8.5 Ω |
Is the inspection result normal?
YES>>Check intermittent incident. Refer to Intermittent Incident.
NO>>There is malfunction of primary pressure solenoid valve. Replace control valve assembly. Refer to Removal and Installation.
