Possible causes

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 “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.

2.CHECK DTC DETECTION
