Official summary
The Engine Control Computer software has a programing error which can cause the exhaust variable valve timing (VVT) locking pin to temporarily get stuck. When this happens, an engine malfunction indicator lamp (MIL) can appear on the dashboard as well as diagnostic trouble code (DTC), P05CE00 to be set.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
