| 10148819 | This SKU is a front upper ball joint.

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. |
| 10109070 | 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 |
