Shift Rod 3 Displacement Sensors
P1734
Diagnosis information - PDK
Shift rod 3 displacement sensors
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
- Line between displacement sensor 3 and PDK control unit faulty
- Displacement sensor module faulty
- PDK control unit faulty
