Gas Gauge Problem

Postby roger » August 23rd, 2004, 10:00 am

tuners, i have been xperiencing a problem with my fuel gauge in the last couple days. When i full up the tank the gauge reads fine and after a little driving, the needle just drops off. So much so that the gas light comes on and the needle goes right down as thought the engine was switched off.

i mean the tank is full and the gauge reads as though it were empty. it's frustrating! any ideas on what cud be causing this?

i drive a mitsu cedia if that helps any.

it's the electrical unit with the float attached that sends the signal to the dash gauge which tells u how much gas u have in the tank

i don't mean to ask a noob question, but how do i service/change it?

do i need to just clean the harness and plug it back in?

any idea where i can purchase a new one if i need to?

It might also be the gauge itself in the instrument panel. But I suspect dave is right.

check the jacks from the sending unit first.It may not be a big problem as expected

when u say "a little driving" do u mean, like minutes after u fill 'er up or like a few days when the level in the tank would've gone down a bit?

I had a similar prob w/ my sender, where the float would push the needle on the rheostat upwards when filling up but by the end of the week, it's telling me I have a 1/4 tank to go when I know I should be on half tank

turns out the needle was loose and the float only held onto it when the level was right up...I suspect it's the same way w/ urs :idea:

the sender unit should either be under a panel in the trunk or under the backseat...but it's best to carry it by ur electrician BUT with a 1/2 TANK of gas (u should know ur car's gas consumption behaviour enough to guestimate when it's 1/2 tank)
I say only 1/2 tank because the prob only happens when the level goes down so let him see for himself what's going on w/ it...hope u get it fixed soon...

OH! and DON'T let anyone tell u u need a new sender for $X-hundred and to leave de money and come back l8r 2 install...most rheostats will work, once adjusted/calibrated properly..

what happens most times, is the little resistance strip that the gauge rubs on is worn out, thus causing faulty readings at different tank levels. If that is the case you need to change the unit/gauge. Your electrician would advise you.
