1995 Honda Passport -- Low Fuel Light Constantly On

What would cause my low fuel light to remain on, even after filling the
tank?

TIA

 

Yeah. Gague works fine. Reads the gas levels all the way down to
empty. When I fill the tank, it goes back to full. The light remains on
all the time, at this point, that's all.

==================

Dented gas tank, or corroded grounding somewhere? Does the guage work at
all?

does the level read low too? if so, it could be a rear impact bending a
baffle inside the tank holding the float still. jacking the vehicle up
by the tank can cause the same problem too.

if the level reads ok independent of the low light, it might be a wiring
problem. electrical problems on the level are either needle hard up for
open circuit, or off the bottom for closed circuit.

Maybe it's LOW octane fuel...

Sorry... couldn't resist.

Great. Now the damned thing is thinking for itself.

Worse than that, it intercepted your email and is coming after you. I am
safe because of this foil hat I'm wearing.

In my 1985 Celica the sender unit had a seperate contact that
closed when the fuel in the tank got low enough. I suspect the
1995 Passport uses a similar setup. If this is the situation, then
the fuel tank will have to be removed and the defective switch
repair/replaced. It is posible, thoguh unlikely that Honda
could have used an electronic voltage sensor to trip the light
when the fuel gauge reads below some set point. Given the
greater complexity, ie expense, I suspect that Honda went
with the same basic sensor that my Celica used.
A diagram of the electronics should show how the light works.
Removing a fuel tank is not hard, be sure to syphon out as much
fuel as you can, a 12 gallon tank full of fuel is, awkward!
IT is not for the faint of heart. Disconnect the battery!
And when I work on the fuel system, I get my wife to stay
close by with Halon. IF it was me, I would almost certainly
ignore the problem.
Good luck.

Yeah. I'm thinking about removing the bulb, at this point.

In my 1985 Celica the sender unit had a seperate contact that
it's the same unit as the fuel level unit. the tanks aren't bad to
drop. having a brass punch to remove the retaining ring is another
thing.
it's an odd animal since it is an isuzu rodeo.
