This may sound crazy, but some time last week if I recall I took a quick look at my gas guage when the gas light went on, and discovered there were 4-5 bars still lit! Then the other day while driving the gas light only appeared when there was like 1-2 bars lit??? Does this sound a lil crazy?

Actually, I believe you. What it sounds like is a typical S2K gas gauge. Not exactly the most precise gauge I have seen.

Ive said this many times....the s2000 gas gauge isnt really a "gauge" it is a gauge/trip computer in one. It calculates the TPS and injectory duty, to tell you how much gas you have if you drive a certain way. Adjust the driving, and the gas gauge will move accordingle. I can manipulate the gas gauge at will.

I was afraid I had a defective guage...glad to hear that this is not out of the ordinary!!! I was not looking foard to having a new cluster installed under factory warranty, then that would lessen the resale value and it would be branded as a TMU (true mileage unknown) even if it is still documented through Honda.

this isn't my experience - my gauge behaves pretty predictably.
when your fuel light came on, and you saw 4-5 bars, did the light
stay on, or did it go off on its own?

Ive had it go down to zero bars, only to return to 3 bars.

If I recall the gas light stayed on when I had 4-5 bars remaining....

oth

there's only one sending unit, which basically provides different
levels of resistance depending on how high the float is. The
instrument cluster then interprets this, and lights up the gauge
and low fuel light. It could read incorrectly either because:
a) gas sloshing around as you turn, brake, accelerate and go up/down hills
b) bad sending unit
c) bad wiring
d) bad cluster
I was originally mystified as to why the low fuel light and the gauge
should disagree as there is only one signal, but I bet the low fuel
warning is designed so that it stays on for a while (maybe until the
key is removed) so that it isn't constantly going on/off when you're
at the threshold. Anyway, I doubt you have a real problem, but
if you do, more likely a bad sender than cluster.

Errr i think the TPS/Inj Duty comment is totally wrong at least for 00-03.. i think the gas gauge for this car is RETARDED.... it works on a system of gas tank level/time to give you the amount of gas. I have run very hard on mountain roads on a half tank during the whole run of using 1 and 2nd and sometimes high third it stays half so you could drive for an hour and as long as you keep the floater sloshing to a high/highest point many times over a specific time the gauge will say half. I even rested the car to let the gauge go to where it should (5mins) it only dropped a bar or two which wasnt right for 20 minutes of low gears. Anyways after running the mountains for about an hour i was finally done and it still indicated just under half. after driving stable for 10-15 minutes i magically had NO BARS.... so for average driving yuh the stupid fuel bars are just an accurate educated guess and the accuracy of the gauge and the fuel low light should be umm treated as a you have 40-60 miles left .. ." Since the car is a sports car whatever feature the designers put in to stop the bars from immediately going up and down when the floater sloshes is too delayed, and its worse off for the car and driver running out of gas is just not good on so many levels (sucking up sediment/ being stranded/leaning engines). This gas gauge issue is something i wish i could undo. we dont need averages we need actual numbers.
