Service bulletin SSM 47158

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 Escape vehicles equipped with a 1.5L EcoBoost engine may exhibit an illuminated MIL on with DTC P051B. This DTC sets when the PCM detects a sensor offset greater than a calibrated threshold just prior to engine cranking or if it detects crankcase pressure outside of the calibrated limit during low engine air flows. If DTC P051B is set with any other codes, diagnose and repair those DTCs first. If DTC P051B is the only DTC, remove and inspect the crankcase ventilation tube and sensor for ice/water. If any ice/water is found, replace the sensor and tube assembly. If no ice or water is found, follow Pin Point Test HG for the crankcase ventilation sensor and note that step HG4 should be performed KOEO only. Engineering is currently investigating. Monitor OASIS for updates.
