Official summary
Some 2018 F-150 vehicles equipped with a 5.0L engine may exhibit an illuminated MIL with DTCs P0390 and/or P0394. These DTCs may be caused by low engine oil level. Before performing any diagnosis or repair, make sure the oil level is between the minimum and maximum marks on the oil level indicator. If the oil level is below the minimum mark, diagnose the low oil level concern first. Refer to the Workshop Manual, Section 303-00. If the oil level is in the normal operating range, inspect C1627. If no concerns are present, replace the bank 2 (LH) exhaust variable camshaft timing (VCT) solenoid. D
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
