Some 2022 Maverick vehicles built on or before 4-Apr-2022 equipped with 2.0L engine may exhibit a charging system warning indicator with diagnostic trouble codes (DTCs) U012D, U0284 and/or U042E stored in the powertrain control module (PCM). The vehicle may also exhibit a malfunction indicator lamp (MIL) with DTCs P0036:00 and/or P0138:00 stored in the PCM. This may be caused by water intrusion in the connector C1050. Prior to performing Workshop Manual (WSM) diagnostics, inspect the male and/or female connector C1050 for signs of corrosion or water intrusion. If water or corrosion is found, replace the male and/or female connector C1050 with a pigtail kit and apply dielectric grease.
