Does speed sensor affect fuel gauge?
If that wheel speed sensor goes bad, your fuel gauge will fluctuate significantly as you drive along – as will your “range” reading. I mean by 1/4 to 3/8ths of a tank. It won’t read zero when you have half a tank, but your range will fluctuate between, say, 6-90 miles.
