Some 2016-2018 Focus and 2018-2019 EcoSport vehicles equipped with a 1.0L EcoBoost engine, 6F15 automatic transmission and built on or before 3-Jul-2019, may exhibit an illuminated oil pressure warning lamp with a loss of engine oil pressure. This may be due to a failed engine oil pump belt tensioner which leads to a loss of engine oil pressure. If engine oil pressure at idle is below 10 psi and/or metal contamination is present in the engine oil, no further diagnostics should be performed. Replace the engine assembly to correct this condition.
