P0966

PC SOLENOID B (Pressure Control Solenoid B Control Circuit Low)

The primary pressure solenoid valve current is 200 mA or less continuously for 480 msec or more under the following diagnosis conditions:

Diagnosis conditions

Solenoid valve output current: 750 mA or more
GND short circuit diagnosis occurs in the solenoid valve drive circuit
TCM power supply voltage: More than 11 V

Harness or connector (Primary pressure solenoid valve circuit shorted to ground)
Primary pressure solenoid valve

DTC CONFIRMATION PROCEDURE

1.PREPARATION BEFORE WORK

If another вЂњDTC CONFIRMATION PROCEDUREвЂќ occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.

>> GO TO 2.

2.CHECK DTC DETECTION

Start the engine and wait for 5 seconds or more.
Check the first trip DTC.

Is вЂњP0966вЂќ detected? YES >> Go to TM-206, "Diagnosis Procedure".

NO >> INSPECTION END

Diagnosis Procedure

1.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.

Is the inspection
result normal? YES >> GO TO 2.

NO >> Repair or replace malfunctioning parts.

2.CHECK PRIMARY PRESSURE SOLENOID VALVE

Check primary pressure solenoid valve. Refer to TM-206, "Component Inspection".

Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".

NO >> Repair or replace malfunctioning parts.

Component Inspection

1.CHECK PRIMARY PRESSURE SOLENOID VALVE

Check resistance between CVT unit connector terminal and ground.

Is the inspection
result normal? YES >> INSPECTION END

NO >> There is a malfunction of primary pressure solenoid valve. Replace transaxle assembly. Refer to TM-283, "Removal and Installation".
