My 2008 Civic no longer updates the fuel economy average guage. how do I test / fix it?
My car has the average fuel economy Guage. It is metric, so
it shows l/100km instead of mpg. But it shows 30. It does
not change. Ever. Even if I reset the trip odometer, the
l/100km remains the same.
Jimmy,you might take the positive battery cable loose and reset the Ecm,if this doe,s not work,you may have internal damage to the guage it self,
