Some 2018-2019 Escape vehicles equipped with a 1.5L EcoBoost engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P051B stored in the powertrain control module (PCM). This may be due to the crankcase pressure sensor. To correct the condition, follow the Service Procedure steps to replace the crankcase pressure sensor.
