Dear Caterpillar Product Owner:
Some throttle position sensors which are used on the products listed
below may have been assembled using a snap ring that is too small. If
the sensor has a snap ring that is too small, the result could be a
malfunction of the sensors.
The throttle position sensors needs to be inspected and possibly
replaced. The repair will be done at no cost to you.
Contact your local Caterpillar dealer immediately and schedule a time to
have this service performed. The time for the inspection is
approximately one hour, and replacement if necessary will take
approximately three hours.
We regret the inconvenience this may cause you, but urge you to have
this service performed as soon as possible to prevent unscheduled
downtime.
