2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 499
Short circuit to ground:
- Setpoint resistance > 0.9 MOhm
Open circuit:
- Setpoint resistance < 2 Ohm
Diagnosis Information - PDK (Dual-Clutch Transmission)
P0841
Diagnostic information - PDK
Pressure sensor clutch 1, measured value implausible
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.
- Engine running
Possible fault causes
- Line between pressure sensor 1 and PDK control unit faulty
- Pressure sensor 1 faulty
- Hydraulic control unit faulty
- PDK control unit faulty
Fault setting conditions
- Measured pressure deviates from the internal plausibility check. Permitted limit was exceeded.
Fault effects
- Engaged gear is held until vehicle stops
- Moving off possible only in 2nd gear
- Only gears 2, 4 and 6 are possible
- Start enable only in selector lever position P
- Transmission limp-home indication in instrument cluster control unit
Pressure Sensor 1, Short Circuit To Ground Or Open Circuit
P0843
Diagnosis information - PDK
Pressure sensor 1, short circuit to ground or 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: P1706
- The following fault is not detected: P1707
Possible fault causes
- Short circuit to ground or open circuit in line between pressure sensors and PDK control unit
- Check sensor ground if the following faults are entered additionally:
P172F, P0711, P0712, P0841, P0843, P0846, P0848, P181B
Fault setting conditions
- Measured pressure < threshold value (0.35 bar)
Fault effects
- Only gears 2, 4 and 6 are possible
- Protective function: gear held and no pressure control
- Start enable only in position P
- No pressure control
- Clutch pressure < holding threshold DH-V (8.1 bar) and torque limitation
- Upward limitation of system pressure
- No emergency program diagnosis
- Only gears 2, 4 and 6 possible
- White transmission limp-home indication in instrument cluster
