Service bulletin TSB-12-7-4

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.

Other bulletins for the same vehicles and component
DOR-N3Z7B-032020-03-30. Service bulletin. This SKU is an Oil Dipstick. The customer communication requested return of unsold inventory to inspect the dipstick tube. The dipstick tube inner diameter may be small enough that it prevents installation of the OE dipstick.
DOR-L2Q6V-102019-10-21. Service bulletin. This SKU is a Radiator Fan. The customer communication requested return of unsold inventory to inspect the electrical connections. An electrical connection issue may lead to the fan not working potentially throwing a check engine light for overheating.
SSM 477972019-04-08. Service bulletin. Some 2009-2017 Expedition/Navigator, 2009-2014 F-150/Mustang, 2008-2009 Sable, 2008-2019 Taurus/Flex/MKT, 2013-2019 Police Interceptor Sedan/Utility, and 2011-2019 Explorer vehicles may exhibit inoperative or intermittent HVAC blower motor function at various fan speed settings. This may be due to a poor electrical connection at the blower motor speed control. If the blower motor speed control is determined to be the causal part, replacement of the electrical connector pigtail harness (14S411) to the blower motor speed control is also recommended to avoid repeat repairs. Refer to Wiring Diagram, Cell 5 for recommended splicing procedures. Refer to Wiring Diagram, Cells 54/55 to obtain the service pigtail connector part number.
SSM 473312018-07-23. Service bulletin. Various vehicles equipped with a 4.6L, 5.4L, 6.8L modular 3 valve engine built on or before 8-Jan-2016 may exhibit symptoms that may include upper end engine noise, rough running, misfire and/or engine damage. If diagnosis leads to only camshaft/camshaft roller follower(s) requiring replacement, replace all of the camshaft roller followers on both banks/cylinder heads with part number 3L3Z-6564-A, not just the faulty roller follower(s). When replacing the camshaft roller followers, refer to Workshop Manual (WSM), Section 303-01.
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.
