See se bolela eng?

Khoutu ena ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang mme e sebetsa ho likoloi tse ngata tsa OBD-II (1996 le tse ncha). Sena se ka kenyelletsa empa ha se felle feela ho Mercedes, Sprinter, Ford, GMC, Chevrolet, jj. Leha e le kakaretso, mehato e nepahetseng ea ho lokisa e ka fapana ho latela selemo sa mohlala, sebopeho, phetisetso le phetiso.

Khoutu e bolokiloeng ea P205A e bolela hore module ea "powertrain control module" (PCM) e fumane matla a sa tloaelehang phepheng ea mocheso oa mocheso oa tanka. Khoutu ena e bonts'oa feela ho likoloi tse nang le enjene e hloekileng ea disele.

Sisteme ea li-catalyst e ikarabella ho fokotsa (haholo-holo) moea o mong le o mong o tsoang, le ha lits'ebetso tse ling li boetse li na le leraba la NOx.

Sistimi ea Exhaust Gas Recirculation (EGR) e nka mohato o mong ho fokotsa mochini oa NOx. Leha ho le joalo, lienjiniere tsa kajeno tse kholo le tse matla haholo tsa dizeli li ke ke tsa kopana le litekanyetso tse thata tsa khase e nang le EGR, DPF / converter ea catalytic le leraba la NOx. Ka lebaka lena, litsamaiso tse ikhethileng tsa phokotso ea lihlahisoa (SCR) li se li qapiloe.

Litsamaiso tsa SCR li kenya mochini o fokotsang kapa Diesel Exhaust Fluid (DEF) ka har'a likhase tse tsoang ka har'a sefahleho sa sefahleho sa leraba, leraba la NOx le / kapa sesebelisoa se fetolang ka mokhoa o fokotsang oa valve (solenoid). Ente e nang le nako e nepahetseng ea DEF e phahamisa mocheso oa sesebelisoa mme e e lumella ho sebetsa ka nepo. E eketsa bophelo ba ts'ebeletso ea likarolo tsa sefa ebile e thusa ho fokotsa mesi e kotsi ea likhase tse kotsi tse tsoang moeeng. Sisteme eohle ea SCR e laoloa le ho beoa leihlo ke PCM kapa molaoli ea ikemetseng (ea sebelisanang le PCM). Leha ho le joalo, molaoli o lekola li-sensor tsa mocheso oa khase oa O2, NOx le exhaust (hammoho le lisebelisoa tse ling) ho fumana nako e nepahetseng ea ente ea DEF (e fokotsang matla). Sebopeho sa Prefision DEF se hlokahala ho boloka mocheso oa khase o le maemong a amohelehang le ho ntlafatsa ho hloekisoa ha lintho tse silafatsang.

Pompo e fokotsang / nchafatso e sebelisetsoa ho hatella DEF tsamaisong ea metsi e fokotsang hore e sebelisoe ha ho hlokahala. PCM e lekola phepelo ea pompo ea phepelo bakeng sa liphetoho tse tsoelang pele le liperesente tsa mojaro. PCM e boetse e lekola sesebelisoa se le seng kapa tse fetang tse ngata tsa khatello tsamaisong ea phepelo e fokotsang ho bona hore na ho na le ho dutla tsamaisong.

Haeba PCM e lemoha boemo ba voltage ho "reductant tank heat sensor circuit" e seng sebakeng se fapaneng, khoutu ea P205A e tla bolokoa 'me lebone la ho se sebetse hantle (MIL) le ka bonesoa. Leseli la MIL le ka hloka lipotoloho tse ngata tsa ho khantša - ha ho ka hloleha.

Mohlala oa tanka bakeng sa ho fokotsa moemeli DEF:

Boima ba DTC ee ke bofe?

Khoutu e bolokiloeng ea P205A e lokela ho tšoaroa ka botebo le ho lokisoa kapele kamoo ho ka khonehang. Sistimi ea SCR e ka holofala ka lebaka la sena. Ts'enyo ea catalyst e ka hlaha haeba maemo a kentseng letsoho kholisong ea khoutu a sa lokisoe ka nako e loketseng.

A mang a matšoao a khoutu ke afe?

Matšoao a khoutu ea bothata ea P205A a ka kenyelletsa:

• Fokotsa matla a mafura
• Mosi o motšo o feteletseng o tsoang ho koloi
• Ts'ebetso ea enjene e fokotsehileng
• Likhoutu tse ling tse amanang le SCR

A mang a mabaka a tloaelehileng a khoutu ke afe?

Mabaka a khoutu ena a ka kenyelletsa:

• Fokotsa moemeli tanka mocheso kutlo haelloang
• Potoloho e bulehileng kapa e khuts'oane potolohong ea mocheso oa mochini oa mocheso o fokotsang
• Taolo e mpe ea SCR / PCM kapa phoso ea mananeo

Ke mehato efe e meng ea ho rarolla bothata ba P205A?

Ho fumana khoutu ea P205A, o tla hloka sekena sa tlhahlobo, digital volt / ohmmeter (DVOM), le mohloli oa tlhaiso-leseling e ikhethileng ea koloi.

U ka sebelisa mohloli oa tlhaiso-leseling ea koloi ea hau ho fumana Technical Service Bulletin (TSB) e ts'oanang le selemo sa koloi ea hau, ho etsa le ho etsa mohlala; hammoho le ho fallisoa ha enjene, likhoutu tse bolokiloeng le matšoao a fumanoe. Haeba u e fumana, e ka fana ka tlhaiso-leseling e nepahetseng ea tlhahlobo.

Sebelisa sekena (se hokahantsoeng le socket ea ts'oaetso ea koloi) ho fumana likhoutu tsohle tse bolokiloeng le data e amanang le foreimi. Ho kgothaletswa hore o ngole tlhahisoleseling lena pele o tlosa dikhoutu mme o leke ho khanna koloi ho fihlela PCM e kena maemong a loketseng kapa khoutu e hlakotsoe.

Haeba PCM e kena ka mokhoa o loketseng ka nako ena, khoutu e bohareng mme e ka ba thata haholo ho e fumana. Maemong ana, maemo a tlatselitseng ho bolokeng khoutu a ka hloka ho mpefala pele ho ka fumanoa tlhahlobo e nepahetseng.

Haeba khoutu e hlophisoa bocha hanghang, mohato o latelang oa ho hlahloba o tla hloka hore o batlisise mohloli oa tlhaiso-leseling ea koloi bakeng sa lits'oants'o tsa "block block", li-pinout, li-faceplates tsa sehokedi le lits'ebetso tsa liteko tsa likarolo.

hata 1

Sebelisa DVOM ho leka mocheso o fokotsang mocheso ho latela litlhaloso tsa moetsi. Likarolo tse hlolehang tlhahlobo kahare ho litekanyetso tse lumellehang li lokela ho nkuoa li haella.

hata 2

Haeba mocheso o fokotsang o le ka har'a litlatsetso, khoutu ea P205A e bolokiloe 'me senotlolo se botsitsoeng sea sebetsa, sebelisa DVOM ho leka lipehelo tsa ho kenya le ho tsoa lipakeng tsa senotlolo sa mocheso le molaoli oa PCM / SCR. Tlosa balaoli bohle pele u sebelisa DVOM bakeng sa liteko.

• Likhoutu tse fokotsang mocheso oa mocheso hangata li amahanngoa le senotlolo se sa sebetseng kapa se sa sebetsoang.

Lipuisano tse amanang tsa DTC

• Hajoale ha ho na lihlooho tse amanang le tsona liforumong tsa rona. Romella sehlooho se secha foromong hona joale.

U hloka thuso e eketsehileng ka khoutu ea P205A?

Haeba o ntse o hloka thuso mabapi le DTC P205A, beha potso litlatsong tse ka tlase ho sengoloa sena.

HLOKOMELA. Tlhahisoleseling ena e fanoa molemong oa tlhaiso-leseling feela. Ha ea rereloa hore e sebelisoe joalo ka khothaletso ea tokiso mme ha re na boikarabello bakeng sa ketso efe kapa efe eo u e nkang koloing efe kapa efe. Lintlha tsohle tse fumanehang sebakeng sena sa marang-rang li sirelelitsoe ka litokelo tsa bangoli.
