Service bulletin TSB19-2164

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2018-2019 EcoSport vehicles equipped with a 1.0L EcoBoost engine build on or before 16-May-2019 may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P051B. This may be due to sensor drift on the crankcase ventilation sensor thresholds. To resolve the condition, follow the Service Procedure to reprogram the powertrain control module (PCM).
