P200B: Audi's runner-overtravel monitor uses a signal-voltage boundary
Audi's CEUC P200B entry describes intake-runner overtravel with a signal below 0.7 V, which requires interpretation within the installed position-feedback system.

Documented application
Audi 2014 A6/S6 Quick Reference Specification Book, September 2013, Engine Code CEUC, DTC chart. Thresholds only describe this documented monitor; not universal across other makes or engines.
The code alone does not identify a failed part or establish that a vehicle is safe to drive. Confirm the vehicle, reporting module and applicable service procedure.
P200B is cataloged as bank 2 intake-manifold runner performance. Audi's CEUC chart describes the code as runner-control overtravel and lists signal voltage below 0.7 V. That is the specific monitor interpretation explained here, rather than a general claim that all P200B faults use the same position or voltage limit.
Overtravel is evaluated through feedback
The source gives a signal boundary, not a measured linkage angle. As diagnostic reasoning, the low signal must be reconciled with the actual mechanism and feedback system before concluding that the runner physically traveled too far. A sensor-related reading and a confirmed mechanical position are separate evidence.
The row also does not provide a motor-current test or prove that the intake manifold assembly must be replaced. It describes detection, not fault isolation.
Confirm the correct runner arrangement
Use CEUC service information to identify the relevant bank, mechanism and feedback circuit. The quick-reference row is not a bank-location diagram and supplies no universal stop adjustment. A supported repair explains why the monitored signal crossed the boundary and which defect caused it. This article is limited to the CEUC section of Audi's 2014 A6/S6 reference book and does not transfer that threshold to other engines.
