Malfunctiong Gas Gauge at 1/4 gas level

[mazda323]

I drive a 94 Mazda 323 car. Its gas gauge pointer points to zero level once it reaches 1/4 gas level and its yellow indicator light does not illuminate. My only gauge if I am running out of gas when the yellow indicator lights illuminates.

How do I fix this problem? Where?

yung "floater mechanism" sa tank defective na or yung mismong gauge defective na rin. mahirap magpalit nyan. dalhin mo na lang sa suking mekaniko mo para mapalitan. mura lang naman yung "floater mech" or the like..............

[bilog]

sometimes the floater can still be fixed. it also needs calibration to correct your indicator. it happened to ny car a year ago, thankfully my mechanic was able to fix it.

dugtong ko na rin...

yung temp indicator ko nman walang reaction..hehe di gumagana. kaya yari ako, di ko alam kunhg overheat na ako nito (wag naman sana)

[ts1n1ta]

have the same problem.
pinaayos ko na yung floater mech ko kaso after a few days ganun pa den. Minsan i fill up the tank pero sa gauge parang 1/3 na lang. Hanggang ngayon ganun pa den, what i do..compute ko na lang liters to kms. para alam ko when to have it filled.. Ahahaha barbaric ang auto ko.

try ninyong mag full tank baka usually 1/4 or up to 1/2 lang pirme pag gas up. eh baka nag stuck na yun floater. try lang ninyo.

As the others have stated, the most likely culprit would be the fuel tank float mechanism.

I would have it changed if I were you for peace of mind.

Yung VW namin half pa lang ayaw nang umakyat. Bakit? Yung arm kasi na may buoyant material makes contact with several wires depending on the level. Siguro dahil mas madalas na may contact sa 1/2 and below, nagdeteriorate na yung mga wires at hindi na masyadong nagko-contact. The solution is to replace the entire floater, though di ko pa naasikaso. The orig was 700 pesos maybe 15 years ago. Hehe.

In your case, madalas sigurong nasa 1/4 and below yan.

Floater ng Benz ko ganun din, pag less than 1/3 nalang sablay na yan, hula hula na hehe.

Buy a new or surplus (working floater). Medyo mahirap iservice ang floater ng mga newer vehicles.

as others said floater mechanism is always the culprit but sometimes its also the wiring na naka negative contact sa tank na naka screw may rust na if ur car has the same configuration. it also happened to my lancer boxtype a few years ago so pinabaklas ko they found some rust on the contact and the floater nilinis nila kasi pag hindi ka madalas mag pa full tank the floater gets stuck.but if the mechanic says linisan ang tank wag kang pumayag that will be the start of a big problem..

i have the same problem with my benz, one it hits 1/4 bagsak na ang gauge. even the red warning light ng gauge nagloloko e.the only time it goes back to normal is when ipa full tank ko..
