MPG gauges show "Err"

MPG Sensor Error

Description:
Many or all of the various MPG gauges display "Err" or nonsensical values.  Other gauges such as RPM, MPH, Engine Temp, display correctly.  This is a common issue on Ford F250 and F350 Diesels.

FIX:

If your UltraGauge version, MENU--> UltraGauge Setup --> Version, is 9/14/10 or later,
please set the "Force MPG sensor" to "MAP".
This is set at: MENU --> Vehicle Setup --> Force MPG sensor.

If your UltraGauge version is prior to 9/14/10, your UltraGauge was disconitnued.  However, it may be upgraded to an UltraGauge EM

Please not that the Ford F250/F350 Diesels are not supported.
