a.
If this unfiltered value exceeds 231 at any point during this test, there is an open circuit in the sender and/or wiring. Refer to Diagnostic
Procedure A for 2002-2005 Model Years and Diagnostic Procedure B for 2006 Model Year.
b.
If the Unfiltered value drops below 28 at any point during the test, there is a shorted circuit in the sender and/or wiring. Repair as necessary.
c.
If the Unfiltered value stays between 028 - 231 during the test, the concern is intermittent. Refer to the appropriate shop manual and follow
normal diagnostics.
Tips For Procedure C And Optional Diagnostics:
^
If F is increasing and FP isn't - go to Cluster Diagnostic Section of Shop Manual
^
If FP and F are increasing and fuel level isn't - go to Cluster Diagnostic Section of Workshop Manual
^
If Last line (Open) values aren't 255 and 254 (MY 05 and before), or 255 (MY 06) - go to Cluster Diagnostic Section of Workshop Manual
^
If Open, or if F does not represent the level of fuel as described - then go to the Workshop Manual and look for wiring and fuel sender issues. The
cluster is not at fault
