Service bulletin PIP5472D

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.

NHTSA's summary

A technician may find Diagnostic Trouble Code P050D set as current or history. The technician is advised to first perform the SI diagnostic. That if the diagnostic fails to isolate the concern, then replace only the exhaust side SHLA's (Stationary Hydraulic Lash Adjuster) and to retest for the concern.
