2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 527
P0966
Diagnosis information - PDK
Pressure regulator 2 (clutch 2), short circuit to ground
Diagnostic conditions
The control unit initially tests internal function sequences when the ignition is switched on (terminal 15). If they are OK, all diagnosable outputs are
then tested and any faults are stored.
- Ignition on
- The following fault is not detected: P1831
- The following fault is not detected: P1839
Possible fault causes
- Line between pressure regulator 2 and PDK control unit, short circuit to ground
- Pressure regulator 2 faulty
- PDK control unit faulty
Fault setting conditions
- Internal current measurement, actuator solenoid R/P: current consumption = 0 mA
- Pressure regulator 2, internally measured control current = 0 mA
- Pressure regulator 2, measured voltage = 0 V
Fault effects
- Power supply switch-off for pressure regulators 2 and 3
- Pressure control switch-off, clutch 2
- Pressure control switch-off for lubrication pressure
- Engaged gear is held until vehicle stops.
- Moving off possible only in 3rd gear
- Transmission limp-home indication in instrument cluster control unit
With P17AA
P0966
Diagnosis information - PDK
Pressure regulator 2 (clutch 2), shunt
Diagnostic conditions
The control unit initially tests internal function sequences when the ignition is switched on (terminal 15). If they are OK, all diagnosable outputs are
then tested and any faults are stored.
- Ignition on
- The following fault is not detected: P0964
- The following fault is not detected: P0966
- The following fault is not detected: P0967
Possible fault causes
- Shunt circuit in line between pressure regulator 2 and PDK control unit
- Pressure regulator 2 faulty
- PDK control unit faulty
Fault setting conditions
- Actual pressure regulator current < setpoint current (maximum deviation = 35 mA)
Fault effects
- Power supply switch-off, pressure regulator clutch 2
- Power supply switch-off, pressure regulator for lubrication pressure
- Pressure regulator, clutch 2, switch-off
- Pressure regulator lubrication pressure, switch-off
- Only gears 1, 3, 5, 7 and R are possible
- Last gear held
- Transmission limp-home indication in instrument cluster control unit
With P17A2
