Affected Component: ENGINE AND ENGINE COOLING

Summary
Some 2018-2020 F-150 vehicles equipped with a 2.7L EcoBoost engine may exhibit an illuminated malfunction indicator lamp (MIL) and/or Engine Coolant Over Temperature warning with diagnostic trouble codes (DTCs) P0116, P0117, P0118, P0119, P0128, P0217, P0330, P1026, and/or P1299. This condition may be caused by an intermittent drop in the engine coolant temperature (ECT) voltage. To correct this condition, replace the heater hose with the new relocated ECT and install a jumper harness.
