Gas mileage / knock sensor
Hi! So I just bought my 2000 Toyota Avalon
XLS and the check engine light came on.
They said it was the knock sensor but that it
could wait a little. Then I started noticing
that my car would go from 1/2 tank up to
3/4 of a tank with out me putting gas on it.
Then I drove to another town on a highway
for about 3-4 hours . I started with a full tank
and the needle didn't drop as much as I
thought it would. It only went down to a little
lower than 3/4 of gas.
Is that normal for a floating fuel gauge
sensor?
If not, does that have to do with the knock
sensor?
