# Service bulletin PIP6113

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

This document provides the technician with a diagnostic tip if the vehicle stalls and set diagnostic trouble code P0191 and may also set P0172. The diagnostic tip has the technician inspect the high pressure fuel pump body markings to confirm it is an original manufacture part. If it is not an original manufacture part, they should install one and evaluate the vehicle.
