2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 542
- Pressure regulator for lubrication pressure, switch-off
- Transmission limp-home indication in instrument cluster control unit
Solenoid Valve 1, Open Circuit
P0973
Diagnosis information - PDK
Solenoid valve 1, open circuit
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: P1832
- The following fault is not detected: P183A
- Solenoid valve 1 active
Possible fault causes
- Line between solenoid valve 1 and PDK control unit faulty
- Solenoid valve 1 faulty
- PDK control unit faulty
Fault setting conditions
- Internal current measurement, solenoid valve 1: current consumption = 0 mA
Fault effects
- Solenoid valve 1 switch-off
- Engaged gear is held until vehicle stops.
- Moving off possible only in 3rd gear
- Transmission limp-home indication in instrument cluster
