Tech Tip: Inaccurate Fuel Gauge Reading on Honda Civics

At any fuel level, the fuel gauge reading drops by 1/4 tank, or three to four graduation marks. In some cases, the fuel gauge indicates "E" and the low fuel level warning light is on. After driving for several minutes, or cycling the ignition switch off/on, the fuel gauge returns to the correct reading.

Vehicles:
2003-2004 Honda Civic 4-door EX ad LX — VIN starts with 1HG or 2HG.

This problem is intermittent, and it affects only Civics with Visteon gauge assemblies.
