High-Pitched “Chirp”, “Squeak” or “Cricket”
Sound from the Engine

INTRODUCTION
The purpose of this bulletin is to provide information regarding a high-pitched “chirp”, “squeak” or
“cricket” sound you may hear coming from the engine’s high-pressure fuel pump. Not all pumps
may exhibit this condition. Some may have a plunger stopper shape which in combination with
certain fuel temperatures or fuel formulations, may result in aeration of the fuel within the body of
the pump and cause this sound when the engine is idling. This result is non-detrimental to the fuel
system or engine. A production change was made to an internal fuel passage along with a change to
the shape of the plunger stopper thus eliminating the source of the sound. Once the sound has been
confirmed, the high-pressure pump assembly must be replaced to remedy the condition.
IMPORTANT: A “clack” or mechanical “ticking” sound may also be heard as part of the operation
of the high-pressure fuel pump which is considered to be a normal operating characteristic. No
attempt should be made to repair it.
