# Service bulletin PIT3046G 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. - Type: Service bulletin - NHTSA id: 10114443 - Published by NHTSA: 2017\-08\-15 - Manufacturer's number: PIT3046G - Manufacturer's date: 2016\-02\-27 - NHTSA component: FUEL SYSTEM, OTHER:STORAGE:FUEL GAUGE SYSTEM ## NHTSA's summary This Preliminary Information communication provides information to the technician about vehicles that have an inaccurate fuel gauge. Technician should drive the vehicle to duplicate the concern. The fuel gauge will have a tendency to falsely indicate a lower fuel level than what is actually present. The fuel gauge will take a few minutes to show the correct fuel level. On vehicles equipped with an automatic transmission no buffering takes place when the transmission is in park or neutral. This is a normal characteristic and no repairs are necessary. On vehicles equipped with a manual transmission the fuel gauge is buffered in all gears and neutral. There is a timer which starts to count up when the clutch is depressed. When this timer reaches its calibrated value the buffering stops. This is a normal characteristic and no repairs are necessary. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2016/MC-10114443-9999.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2016/MC-10114443-0001.pdf) The document is the manufacturer's.
