2010 Porsche Panamera Turbo (970) V8-4.8L Turbo A L L Diagnostic Trouble Codes ( DTC ): P Code Charts Page 485
Transmission oil temperature sensor, signal 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.
- Ignition on
- The following fault is not saved: P1831
- The following fault is not saved: P1832
- The following fault is not saved: P1839
- The following fault is not saved: P183A
Possible fault causes
- The measured oil temperature deviates from the calculated temperature
Fault setting conditions
- The measured temperature does not match the calculated temperature
Fault effects
- The calculated temperature value is used
- Transmission limp-home indication in instrument cluster
With P0712
P0712
Diagnosis information - PDK
Transmission oil temperature sensor, signal 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.
Possible fault causes
- Line between temperature sensor and PDK control unit faulty
- Temperature sensor faulty
- PDK control unit faulty
Fault setting conditions
- Measured sensor voltage < 1.18 V
Fault effects
- An internal temperature substitute value is used
- Transmission limp-home indication in instrument cluster

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).
