## Other bulletins for the same vehicles and component

- [DOR\-N3Z7B\-03](/bulletins/10172885.md), 2020-03-30, Service bulletin: ENGINE AND ENGINE COOLING. 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.
- [SSM 47331](/bulletins/10143079.md), 2018-07-23, Service bulletin: EQUIPMENT; ENGINE. 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.

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.
