Nissan Sentra 98 fuel level indicator not working properly

**Aoshinomori** · August 30th, 2012 12:56 PM

Hi,

The fuel level indicator is erratic. Sometimes it will go up and indicate that it's full (but I'm pretty sure it's not) and right now it doesn't respond much and stays near the empty level. My friend suggests to have the float checked, which he says will take a lot of work because the tank has to be disassembled and so. Is there an easier way to fix this?

aside from the floater, you can also have the sensor checked muna... baka nandun lang..
pero there is no other easier method to do that, talagang baba ang tangke...

pero, imho, di naman ganung kahirap yun ah.... drain tank, onting kalas-kalas lang sa ilalim, dismount the tank and check/replace the floater, mount and balik yung gas.

kung ipapaayos mo, make sure na lang na yung tank mo is the near empty level.... it would also give you time and opportunity to have the tank cleaned na din siguro.

Hmm tantiya ko me 8 liters pa, I've have it checked and update this thread of the outcome. Medyo important sa akin yung accuracy ng fuel level eh. Thanks for the suggestion, sensor muna then floater.

if memory serves me right, i believe access to the fuel sending unit is just under the rear seat. remove the rear seat, and you will see the cover of the access hole to the fuel tank under it... but be sure your battery is disconnected! baka mag-spark and ... heh heh..
but truthfully speaking (sa totoo lang), i don't remember.. sa dami kasi ng rear seats na kinutingting namin... sorry... senior moments..
but i think it's easier to inspect the sending unit / float, than to gain access to the gauge..

tama si dr d, baka may access hole pa ito sa flooring. tanggalin ang rear seat cush at makita mo naman kung may access hole ito. kung me access hole, malaking luwag na sa trabaho. kapag nakalas mo ang access hole, makakalas mo na rin ang fuel sender unit. tama rin ang tips, dapat tanggalin muna ang battery. ngayon kung nakalas mo na ang fuel sender unit, iangat mo ito, tanggalin mo rin muna ang terminal para sa fuel pump. i on ang ign switch at galaw galawin ang float level. kapag tumaas ang gage mo, buo ang float mo. may mga kaso talaga na kung minsan, dahil sa corrosion (at bihirang mag full tank, gaya ko, he he), yung parang resistor nung float , na g corrode. apply ka lang ng electrical contact cleaner.at ok na uli . dapat mga 2 tao kayo na nagalaw. mahirap kapag nag iisa ka. tip din, huwag kalimutan magpalit nung o ring. after kasi ito ma expose sa gasolina na expand ito. di ko ma recall yung size nya, pero hindi ko ma advise na pumunta ka sa binondo a bumili ng o ring na kasuakt nung kinalas mo, baka mag ka problema ka., bili ka na lang sa dealer nung o ring nya. pero baka naman may ibang kasama natin na may alam na nag offer na ng replacement na o ring

Kahapon umangat ulit yung gauge up to middle level, baka nga corrosion. Dapat pala mag full tank, thanks sa tip, although di pa na-iinspect. Salamat marami ako natututunan mga sir. Di ko pa naayos so issue still persist, hopefully sa next weekend maayos na namin.

Nagpa-full tank ako nung last week, umangat na ng todo (pero unti unti) yung gauge, so hopefully ok na ulit. Thanks sa suggestions! Baka corrosion ang issue.

unti-unti talaga ang pag-akyat niyan. many cars do..
ang natatandaan ko lang na instant akyat ay ang old air-cooled VW beetle. purely mechanical kasi ang gauge..

SA akin naman pag binuksan ang aircon tumataas ng sobra sobra SA full tank. Sentra Lec 94 SA akin. Pag nagpapa-gas ako umaangat naman sya. At bumababa din pag nauubos na. Basta lng pag ini-ON ang aircon saka tumataas ng sobra ang gauge
