2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 594
- Transmission limp-home indication in instrument cluster control unit
Setpoint Definitions
P1706
Setpoint definitions
NOTE: The specified values and value ranges correspond to the OK state in each case.
Line test setpoints
Short circuit to B+:
- Setpoint voltage -0.5 V --> +0.5 V
Short circuit to ground:
- Setpoint resistance > 0.9 MOhm
Open circuit:
- Setpoint resistance < 2 Ohm
NOTE: The specified values apply only at an ambient temperature of approx. 20 锟斤拷C (68 锟斤拷F) (room temperature).
Control unit setpoints
- Supply voltage for pressure sensor and displacement sensor 5 V
- Supply voltage for speed sensor 8.5 V
Diagnosis Information - PDK (Dual-Clutch Transmission)
P1706
Diagnosis information - PDK
Sensor supply voltage 5 V too low
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: P1752
Possible fault causes
- Line between pressure sensors and PDK control unit faulty
- Line between displacement sensor module and PDK control unit faulty
- Pressure sensor 1 faulty
- Pressure sensor 2 faulty
- Displacement sensor module faulty
- PDK control unit faulty
Fault setting conditions
- Sensor supply voltage < 4.5 V
Fault effects
- Gear held
- No R gear
- No emergency program diagnosis
- Transmission limp-home indication in instrument cluster control unit
Sensor Supply Voltage 8.5 V Too Low
P1707
Diagnosis information - PDK
Sensor supply voltage 8.5 V too low
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: P1752
