Service bulletin UPS-16-U-11-S1

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

TSB 22-20892022-03-15. Service bulletin. Some 2015-2022 F-150, 2017-2022 F-Super Duty and 2018-2022 Expedition/Navigator vehicles may exhibit poor air conditioning (A/C) performance, loss of airflow and/or engine cooling fans running continuously from high A/C pressures. This concern may be from the evaporator freezing up due to the evaporator temperature sensor being biased. To correct the condition, follow the Service Procedure steps to replace the evaporator temperature sensor.
TSB 21-22502021-09-30. Service bulletin. Some 2015-2020 F-150, 2017-2020 Super Duty and 2018-2020 Expedition/Navigator vehicles may exhibit poor air conditioning (A/C) performance, loss of airflow and/or engine cooling fans running continuously from high A/C pressures. This concern may be from the evaporator freezing up due to the evaporator temperature sensor being biased. To correct the condition, follow the Service Procedure steps to replace the evaporator temperature sensor.
TSB 20-21502020-06-04. Service bulletin. Some 2015-2019 Transit vehicles built on or before 31-Dec-2018 and some 2017-2018 E-450 vehicles equipped with a 6.8L engine built on or before 16-Jul-2018 using the Motorcraft Orange coolant may exhibit an engine overheat concern. This condition may be due to deposits from the engine coolant becoming trapped in the radiator preventing coolant flow. To correct the condition, flush the cooling system, replace the radiator and fill with Motocraft Yellow coolant.
SSM 477912019-04-08. Service bulletin. Some 2015-2019 F150/Edge, 2016-2018 MKX, 2019 Nautilus and 2017-2019 Fusion/Continental vehicles equipped with a 2.7L engine may exhibit a malfunction indicator lamp (MIL) and/or wrench lamp with diagnostic trouble codes (DTCs) P0116, P0117, P0118, P0119, P0217, P0330, P1026, and/or P130D. This may be due to a engine coolant temperature (ECT) sensor connector which is not fully seated or damaged wiring between connectors C1064 and C1047 for F150 and C1016 and C1168 for Edge/MKX/Nautilus/Fusion/Continental vehicles. ECT sensors should not be replaced if damaged wiring is found at or near these connectors. For claiming, use causal part 12A699 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 460852017-08-01. Service bulletin. The Powertrain Control/Emissions Diagnosis (PC/ED) manual has been revised for diagnosing electronic throttle bodies (ETBs). The ETC_ACT and ETC_DSD PIDs should not used to diagnose possible ETB concerns. The IDS has a limited refresh rate when reading these PIDs and cannot display quickly enough to validate a concern. The PCM automatically monitors these inputs more accurately and will set diagnostic trouble codes (DTCs) when appropriate. Using these PIDs for diagnostics will lead to inaccurate results and improper ETB replacements. If a concern is intermittent and no DTCs are present, refer to historical DTCs and the PC/ED, Section 3 No DTCs Present Index chart for further information.
16U112016-07-07. Service bulletin. Coolant Concentration Adjustment In some of the affected vehicles, the engine coolant to water concentration may be less than specification. Low coolant concentration could result in reduced cooling system freeze protection, reduced corrosion resistance, heater and radiator performance degradation, and water pump noise or leaks.
