Some 2017 Escape equipped with a 1.5L EcoBoost engine may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P04DB stored in the powertrain control module (PCM). This may be due to the crankcase pressure sensor/tube assembly. To correct the condition, follow the Service Procedure steps to replace the crankcase pressure sensor/tube assembly and reprogram the PCM.
