Mass Air Flow sensor - sida in uu eego? DMRV shidma

MAF shidma (DMRV) waxaa ku lifaaqan filter hawada, iyo go'aamisa xaddiga hawada loo maray iyaga. From qeexidda saxda ah ee tilmaamahan ay ku xiran tahay tayada ey isku guban kara. Unu mass shidma socodka hawada isla markiiba saameyn hawlgalka engine ah.

calaamadaha dhaawac

At calaamadaha ugu horreeya ee xadgudub ku ah engine ma u baahan tahay in argagixin, rush dukaanka, oo waxay qaadan DFID cusub. Waxaa laga yaabaa in lagu soo jeediyay in dhaawici shidma socodka hawada. Sidee si uu u hubiyo in uu shaqada? Marka hore, waxaad u baahan tahay si fiican u dhegaysato gaariga. Waxa uu tilmaami doonaa in shidma gardaran DFID, iyo dhaqmaan doonaa sida soo socota:

• computer siin ah baadi «Check Engine» doonaa;

• la yareeyo awoodda;

• isticmaalka shidaalka kordhay;

• waxa ay noqon doontaa xun si ay u bilaabaan engine ah;

• hoos u hadlaya.

ma waxa aan si sax ah u shaqeeyaan haddii shidma socodka hawada mass? Sidee si uu u hubiyo xaaladda?

Xulashada 1: Disable

Marka engine la joojiyay la isku xira goostay DMRV. barkinta doono qalabka, dirato kici doonaa in hab degdeg ah, iyo shidaalka isku dar ah waxaa la diyaarin doonaa iyada oo la tixgelinayo booska hadda ceejinta ah. On kala guurka galay hab this mar kale u sheegtaa engine ee, waa in socdo in ka badan 1500 rev / min. The gunaanad final Dambigooda DFID samayn karaa marka aad wadid gaari waxaad ogaatay in dhaqdhaqaaqii hagaagtay ka dib markii shidma uu dansan yahay. Fiiro gaar ah: beddelka computer The I-7.2 iyo I-7.9.7 ka dib markii goynta DMRV ma kordhiyo xawaaraha engine ah.

Xulashada 2. firmware

Waxaa macquul ah in computer ayaa hore u la soo habeeyay firmware ah, ka dibna u ma cadda sida uu u dhaqmi doono marka la isticmaalayo fursadaha kor ku xusan. Xaaladdan oo kale, waxaa laga yaabaa in sidoo kale ma shaqeeyaan shidma socodka hawada mass. Sidee baan u hubsan kartaa? Qaado saxan of 1 dhumucdiisuna mm iyo geli hoos stop marinka ka. Marka kor u xawaaraha engine, terminal ka furid la DMRV. Haddii engine sii in uu ordo, ka dibna keena qalad ah in unit gacanta, kuwaas oo in wadadii IAC ah. Iyagu ma ay jawaabaan hab degdeg ah oo aan DMRV ah.

Xulashada 3: Cilad-multimeter

muuqashadii noocan oo kale ah waa ku haboon cudurka dareemayaal Bosch la indices: 0280218004, 0280218116, iyo 0.280.218 ahaatid 037. Wixii xadka cabbirka dhigay 2B, in hab joogto ah danab. Xarkaha (orientation of qol ah)

• signal Input - huruud ah,

• sahayda sensor - cawl iyo caddaan,

• Ground (laga jaray) - cagaaran,

• By Relay ugu weyn - casaan iyo madow.

Fiiro gaar ah:

Midabada oo silig lagu tilmaamayaa in inta badan ee lagu daydo, midabo la bedeli karaa, laakiin qiimaha waa gabagabadii isku.

HABKA cabiraada

Ka dib markii suuroggalaan, idinkoon bilaabin engine ah, qabtaan iskaanka. qalab Red xirmaan baaritaan si DFID ee silig huruud iyo madow si cagaaran. Sidaas awgeed, waxaan qaban cabbirka danab iyo hagaaji. Isbarbar akhrinta la talooyinka soo saaraha ee, kaas oo lagu xukumi doonaa on waxqabadka qalabka. New DFID ayaa V. danab a 0,996-1,01

beegyada uu qaab qalab, taas oo ku xidhan danab ah:

1.01-1.03 - shidma functional;

1.03-1.04 - functional, laakiin nolosha shidma yahay ku dhawaad daalay;

1.04-1.05 - khayraadka daallan, haddii calaamadaha aan joogo, aad ka faa'ideysan kartaa, laakiin waxa la joogaa wakhtigii si aad u iibsato cusub mid;

1.05 oo dheeraad ah - waa haleysan, bedelka loo baahan yahay.

Fiiro gaar ah:

Si ay u tijaabiso socodka mass shidma hawada, aan ka baran karno computer safarka on-beegyada "shidma danab" ah.

Xulashada 4: kormeerka Visual

Isticmaal kaashawiito ah si ay u wareejin clamps tuubadu, ay heerka corrugation, kormeerto ku shidma iyo corrugation ah. All sagxadaha waa in uu ahaadaa mid engegan oo lacag la'aan ah ka kayd shidaal oo condensate. Sababaha DMRV wasakhda:

• A filter hawada wasakhda ah,

• Heerka saliidda uu ka badan yahay sida caadiga ah;

• dhaafiyay strainer, nidaamka hawo ah.

Baabi'iyo sababaha wasakhda DFID, waa in la saxo iyo cawaaqibka, iyo waxay u baahan doontaa nadiifinta shidma MAF ah. Iyada oo la adeegsanayo fure 10, by dabciyeen handarraabbadeedii fiiriyey shidma, waxay ku kala baxaan filter hawada. shidma waa in uu faraanti caag si looga hortago cayriin nuugid hawada a. Haddii maqan ama aan ku taalla goobta, talooyin ku mesh qalabka su'aasha boodhka ku jiro. Tani waxay keeni kartaa shidma si cillad. xigxiga Rakibaadda:

• qalabka waa xanjo quwad madhay,

• xaqiijin darafkii dhagixiina way;

• shidma la dhajinta in guryaha filter ah.

Nidaamka bedelka The

Deminta suuroggalaan ah, ka saar fur shidma. By dabciyeen clamps ah, barkinta tubada hawada. shidma Next wareejin oo ka guryaha filter saaro. Si aad u jilco, waxaad u baahan tahay in ay muhiim ah 10. ka dib su'aal imtixaanka mar kale sara joogsan doontaa, in haddii shidma waa socodka hawada mass haleysan yahay, sida loo hubiyo in ay qaab ciyaareed. Qiimaynta cudurka ee gobolka ka mid ah qalabka, ha oo kaliya ma soo iibsan cusub. Waa in la sheegay in DFID kici safafka ka 1,500 2,000 rubles. Laakiin aad ka saari kara wasakhda ka nafaqeeya ugu badnaan 200 rubles.

Ka dhigan tahay in meesha laga saaro sunta

Si aad u tayo maydho DFID, waa in laga saaraa, nidaamka ay ka saareen hore hore u tilmaamay. Inside qalabka jiro mesh a. 2-3 dhexdeeda ku rakiban shidma ah ee foomka of silig ka yar. Inta lagu jiro hawlgalka, qaybo ka mid yihiin wasakhaysan, taasoo keentay in cillad. Si loo siiyo nolol labaad ay u qalab, nadiifiso mesh iyo dareemayaal ku haboon nadiifiye carburetor this. Buufin, wasakhda ka qayb hoose oo DFID maydhaa off. saarista oo dhamaystiran sunta laga yaabaa in aysan dhicin markii ugu horeysay, waxay yeelan doonaan si ay u soo celiyaan nidaamka. xereen ku xiga oo dhan waa in la fuliyaa ka dib markii wakiilka qalajiyo. Iyada oo lagu nadiifiyo shidma, tuubooyinka waa in la baaro gobolka - joogitaanka sunta inuu iyaga ka dhaqaajiyo. Codsiga of loola tirtirida nijaasta ka carburetor waxay muujinaysaa in 8 ka mid ah 10 ka dib markii qalabka daaweynta bilaabaan in ay u shaqeeyaan hab sax ah. Laakiin mararka qaarkood waxaa lagama maarmaan ah si ay u iibsadaan a shidma cusub DFID.

gunaanad

Haddaba hubi DFID on gaar ah la oran karo waa dhameystirtay. Oo Su'aasha ah in shidma socodka hawada mass waa haleysan yahay, sida loo hubiyo in ay xaaladda, in ay ka jawaabaan la 100% damaanad ah in ay awoodaan in xarumaha adeegga, baadhitaan lagu ogaanayo fuliyay iyadoo la isticmaalayo qalab gaar ah.
