Senzor za gorivo VAZ, znaki okvare senzorja vozila za gorivo, neuspešna sredstva

Ko se gorivo konča, izbira lastnika majhnega avtomobila - ali ponovno obnovite avto, danes pa je najcenejši užitek ali hoditi. Seveda, vsi vozniki običajno izberejo prvo možnost, vendar verjetno ne bi smeli biti v takih situacijah, ko morate odločitev takoj. Da bi se izognili takšnim težavam in senzorjem nivoja goriva.

Senzor nivoja goriva - naprava (DUT)

Digitalni fotoaparat Olympus.

V tem članku bo naša pozornost usmerjena v vozila, kjer se uporablja za označevanje ravni goriva, pretvorbo te ravni v glasnost in prenos nastalih vrednosti z digitalno ali analogno potjo.

Ta naprava je sestavljena iz kovinske palice, nameščene v rezervoar za gorivo s standardno odprtino ali posebej izdelano luknjo, primerno za premer. Senzor je priključen na nadzorni sistem avtomobila, kjer se prenašajo zahtevani podatki.

Pogosto so visoko natančne univerzalne naprave, ki jih je mogoče uporabiti ne le v prometu, in na drugih tehnikah, in celo v stacionarnih objektih - rastline, skladišča. Ta enota je tesno povezana s kazalcem nivoja goriva na armaturno ploščo.

Do danes obstaja vrsta variacij DUT - univerzalnega, ultrazvoka, float, digitalnih, elektronskih, vendar njihov skupni cilj je ena - pravilna opredelitev porabe rezervoarja za gorivo, tako da ima vsak voznik sposobnost nadzora stroškov goriva . Poleg tega naprava omogoča spremljanje količine slive (najbolj uporabna možnost za taksi storitve, upravljavci podjetij in drugih organizacij, v katerih so zaposleni sposobni združiti bitno gorivo) in bencinske črpalke (v katerih količinah, ko in kjer so bili izvedeni).

Za možnost podrobnejšega nadzora nad ravni goriva, je treba namestiti ustrezno napravo z minimalno napako in povečano občutljivost na avto, ki bo zagotovila najbolj natančne kazalnike.

povezovanje senzorja nivoja goriva

Obstajata dve metodi povezovanja na omrežje vozil na vozilu, katerih zasnova vključuje množično stikalo:

  1. Povezovanje z omrežjem na vozilu po množičnem stikalu. Senzor, ob istem času, bo izklopljen takoj po izklopu mase avtomobila. V tem primeru boste nemogoče izvedeti čas odtoka, ko bo parkirišče - senzor bo izklopljen. Ta metoda povezave je priporočljiva za poceni senzorje, kjer ni Galvanic Junction.

  2. Neposredno povezovanje senzorja na baterijo. Ta metoda povezave je idealna iz praktičnega in funkcionalnega vidika. Poleg tega je povezava najava neposredno na baterijo, je varna, saj je poraba toka senzorja le 10-48 mA. Priključite senzorje PRO senzorjev neposredno na baterijo, saj se odlikujejo po prisotnosti vgrajenega galvanske križišča do 3000 V. Poleg tega je polimerno telo tega senzorja izolator, zaradi katerega so vsi električni tokokrogi varno zaščitena pred električno okvaro. Če želite povezati druge senzorje neposredno na baterijo, boste morali namestiti dodatno galvansko križišče.

Senzor nivoja goriva ne deluje

Dut, kot vsi drugi elementi avtomobila, lahko sistematično ne uspejo, kar povzroči potrebo po popravilu. Zdaj bomo podrobno razmislili najpogostejši vzroki tega pojava:

  1. Če se odčitki nenehno spreminjajo (»Download«), so bile kontaktne skladbe obrabljene na plošči, na katero vpliva čas, kot posledica dejstva, da se Runner naprava nenehno premika. Če izbrisana območja ni velika, poskusite dobiti drsnik, tako da se nahaja nad izbrisanim mestom, vendar pa bo z velikim depoznim območjem mogoče rešiti problem samo z zamenjavo senzorja.

  2. To se zgodi, da s polnim rezervoarjem za gorivo, senzor indeks arrow vrne na ničelno vrednost. Možen vzrok tega pojava je nepravilno postavljen omejevalnik lokacije.
  3. Z zagonom motorja in vklopljenega vžiga, indeksna puščica ostane fiksna. Kot pravilo, razlog je poškodovan na povezovalne žice, oksidacijo svojih nasvetov, okvaro kazalca sprejemnika ali v varovalko pogumni.

  4. Če se indeks nivoja goriva puščica nenehno pade na ničelno vrednost in, medtem ko je treba tudi trzanje, je treba preveriti trenutni kolektor, verjetno ni dovolj za upor senzorja, ali navijanje upora rezano.
  5. Poleg tega lahko minimalna opozorilna svetilka za gorivo v rezervoarju ne more delovati ali nepravilno delati, s prekinitvami. V tem primeru je najverjetneje problem v uporu in ga je morda treba zamenjati.

Najpogostejši problem potenciometričnih senzorjev je hitra obraba, pa tudi oksidacija skladb kot in se določi z videzom zgoraj opisanih težav.

Preverite senzor za gorivo VAZ

Prvič, preverite odpornost senzorja, za katerega je potrebno narediti naslednje manipulacije:

004-1knuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuug9555555555555555555555555555.

  1. Odstranite zadnji sedež.
  2. Zaščitni pokrovček odvijamo, da je VAZ na zadnjem sedežu.
  3. Odvijemo dip in ga nežno vzemite iz plina.
  4. Nato izklopimo multimeter na način ohmmeter in izmerite odpornost senzorja v pogojih različnih položajev plavajočega: če plavajoči nosijo pod lastno težo, mora biti odpornost od 280 do 330 ohmov; Ko dvignete plavajoče navzgor, mora biti upor od 7 do 20 ohmov. Treba je omeniti, da so te vrednosti podane za nizko armaturno ploščo (armaturna plošča je tudi visoka - številke za nizke in visoke nadzorne plošče so nekoliko drugačne).

  5. Če se pri premikanju plava, upor senzorja ne spremeni ali se bistveno razlikuje od želenega, je treba ta senzor zamenjati.
  6. Z dobrim senzorjem je treba skrbno preučiti s svojim priključkom in žico za maso, ki prihaja iz senzorja. Ror in oksid je treba odsoten, ker posegata v njegovo pravilno in pravilno delo.

Če senzor deluje, in indeks nivoja goriva ne deluje natančno, naredimo naslednje:

  1. Priključek senzorja za gorivo je značilna prisotnost dveh žic - roza in modra. Nizka svetilka za gorivo deluje modro v rezervoarju, iz arrow indikatorja na roza.

  2. Oboroženi s skakalcem (del običajne žice) in s svojo pomočjo pri vžigu je obrnil na zapiranje rožnate žice za maso. V tem primeru mora puščica na ravni goriva pokazati celoten rezervoar za gorivo.
  3. Nato, s pomočjo skakalcev, se povežemo z maso modre žice - svetilka nizkega goriva v rezervoarju se mora obrniti.
  4. Če se med zaprtjem mase, kazalec ne bo deloval, nato razlog ali v samem kazalcu, ali v eni izmed žic iz senzorja za gorivo na armaturno ploščo.

Zamenjava senzorja nivoja goriva

Če senzor nivoja goriva nepravilno kaže, ga je treba zamenjati. Če želite to narediti, boste potrebovali:

  1. Novi senzor.
  2. Crosshead izvijač.
  3. Rozhkovske kape ali glave.
  4. Izvijači.
  5. OMMMETER.

Opozoriti je treba, da je senzor v neposrednem stiku z gorivom, zato je treba upoštevati določena varnostna pravila. Najprej izklopite baterijo. Baterije ni treba popolnoma odstraniti, samo odklopite žico minus s terminala. Nato razstavite senzor (kako to storiti, gledamo spodaj). Namestitev novih servis izvede v obratnem vrstnem redu. Ko se montaža, je zaželeno, da dodatno obdelamo mesto priključka tesnila in tlačnega obroča s pomočjo plinsko odporne tesnilne mase.

kako odstraniti senzor nivoja goriva

Če želite odstraniti najboljše, naredite naslednje:

  1. Dvignite sedež druge vrstice.
  2. Nato je potrebno očistiti območje tehnične lopute iz nakopičene umazanije in prahu.
  3. Z uporabo prečnega izvijača obrnite vijake, ki držijo loputo.
  4. Odklopite kabelski snop priključka.

  5. Nato obrnemo ključ na "17" in odvijemo cevi za gorivo na stran, tako da ne motijo \u200b\u200brazstavljanja telesa bencinske črpalke.
  6. S pomočjo ogrinjalnega glave na "7" obrnemo pritrdilne matice, ki pritrjujejo tlačni obroč.
  7. Če nuts Zakisli, uporabite WD-40 ali druga podobna sredstva.
  8. Odstranjevanje vseh priključkov in potiskanje obroča, nežno odstranite celotno vozlišče iz rezervoarja za plin, skupaj z ročico in float.
  9. Naslednji korak je odvisen z uporabo vijaka s skorjo dva vijaka, ki držita senzor in sproščanje električnega priključka črpalke.
    6F17EB6396B6EC174361AE2C5962B0A6.
  10. Nato vzamemo vodnike iz ohišja črpalke (objemke je treba obnoviti z izvijačem).
  11. Na pokrovu črpalke se odvijamo vijake, držimo matice s tipko na "5".
  12. Odstranjevanje pokrova, dobite dostop do senzorja.

Popravilo senzorja nivoja goriva

Kot je navedeno zgoraj, se najpogostejši vzrok neuspeha ali nepravilnega dela najdete - obraba kontaktnega posnetka senzorja. V tem primeru lahko premaknete Runner na delovni (nestalni) del proge, malo iskrenje tekača. Poleg tega preverite "maso" vrtinčenje pod "WANDLER" za korozijo. Tudi popravilo bo morda treba uničiti stike senzorjev.
