# Service bulletin SSM 47203

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 if the crankcase pressure sensor voltage is greater than a calibrated threshold. If DTC P051B is set with any other codes, diagnose and repair those DTCs first. If DTC P051B is the only DTC, use the Integrated Diagnostic System \(IDS\) datalogger and monitor CRNKCAS\_P\_V at KOEO for 10 seconds without tapping/disturbing the sensor or connector. If the sensor voltage is found to be less than 3.7V or more than 4.1V, replace the crankcase sensor/hose assembly and leave the sensor connected to the hose. If the hose assembly is replaced, record the sensor voltage in the claim or make a recording of the CRNKCAS\_P\_V at KOEO with the original sensor and upload the session to the server. Engineering is currently investigating. Monitor OASIS for updates.
