Service bulletin Plant Comm JEP

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

JEP has identified an issue where TIR runout on the OD of the sensor plate was found to be outside of the total tolerance range resulting in FC778. To mitigate disruption at Navistar we are requesting to replace the sensor plate in engines at EAP and the Expeditors Warehouse.

The document

Listing a model year does not mean every vehicle of it is concerned: the document says which.
