P2452 - Potoloho ea Sensor ea Khatello ea Diesel Particulate

Khoutu ea mathata P2452 e bolela'ng?

Khoutu ena ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang, ho bolelang hore e sebetsa ho makoloi ohle ho tloha ka 1996 (Ford, Dodge, GMC, Chevrolet, Mercedes, VW, jj.). Le ha e le ka kakaretso, mehato e ikhethileng ea ho lokisa e ka fapana ho latela mofuta / mofuta.

Haeba koloi ea hau e bontša enjene ponts'o ea ts'ebeletso e tsamaeang le khoutu P2452, module ea powertrain control module (PCM) e fumane ho se sebetse hantle potolohong ea motlakase ea senotlolo sa khatello ea DPF, se khethiloeng A. Ho hlakile hore khoutu ena e lokela ho hlahisoa feela likoloi tse nang le enjene ea dizeli.

DPF e etselitsoe ho tlosa liperesente tse mashome a robong a likaroloana tsa khabone (mosili) ho tsoa likhasong tse fehlang motlakase. Soot hangata e amahanngoa le mosi o motšo o nyolohang mosi oa mokelikeli ha enjene ea dizeli e le tlasa matsapa a matla. DPF e lutse kahare ea tšepe e hahelletsoeng kahare e ts'oanang le mofetoleli o sa fetoheng. E fumaneha noka ea mofetoleli oa catalytic le / kapa leraba la NOx. Ha likaroloana tse kholo tsa mosili li qabeletsoe nthong ea DPF, likaroloana tse nyane le metsoako e meng (likhase tsa ho qeta) li ka feta ho eona. DPF e sebelisa mefuta e fapaneng ea metsoako ea mantlha ho ts'oara mosili le ho fetisa likhase tsa ho ntša enjene. Tsena li kenyelletsa pampiri, likhoele tsa tšepe, likhoele tsa ceramic, likhoele tsa mabone tsa silicone le likhoele tsa mabota a cordierite.

Cordierite ke mofuta oa filtration e thehiloeng ho ceramic le mofuta o atileng haholo oa fiber o sebelisoang ho lifilthara tsa DPF. E batla e le theko e tlase mme e na le litšobotsi tse ntle haholo tsa ho sefa. Ka bomalimabe, cordierite e na le mathata a ho qhibiliha mochesong o phahameng, e leng se etsang hore e senyehe habonolo ha e sebelisoa lits'ebetsong tsa li-filter tse sa sebetseng.

Pelo ea sefe kapa sefe sa particulate ke karolo ea sefe. Ha mosi oa enjene o feta har'a element, likaroloana tse kholo tsa soot li qabeletsoe lipakeng tsa likhoele. Ha mosi o ntse o eketseha, khatello ea khase ea mouoane e eketseha ka ho loketseng. Hang ha mosili o lekaneng o se o bokeletse ('me khatello ea mouoane e fihlile tekanyong e hlophisitsoeng), karolo ea sesefe e tlameha ho nchafatsoa ho lumella likhase tsa mouoane hore li tsoele pele ho feta DPF.

Sistimi e sebetsang ea DPF e itlhahisa ka bo eona. '' Ketso ena e etsa hore mocheso oa likhase tsa ho qeta o nyolohe 'me likaroloana tsa mosili tse qabeletsoeng li chesoe; ho li lokolla ka mokhoa oa naetrojene le li-ion tsa oksijene.

Ts'ebetso e ts'oanang e sebelisoa lits'ebetsong tse sa sebetseng tsa DPF, empa e hloka ho nka karolo ha mong'a eona le (maemong a mang) ho lokisa e tšoanelehang. Kamora ho qala ha ts'ebetso ea nchafatso, ho ka nka lihora tse 'maloa. Lits'ebetso tse ling tsa nchafatso li hloka hore DPF e tlosoe ka koloing ebe e sebeletsoa ke mochini o ikhethileng o phethelang tšebetso le ho tlosa likaroloana tsa mosili hantle. Ha likaroloana tsa mosili li tlositsoe ka ho lekana, DPF e nkuoa e nchafalitsoe mme khatello ea mokhathala e tlameha ho arabela hantle.

Maemong a mangata, senotlolo sa khatello ea DPF se kentsoe ka phapusing ea enjene, hole le DPF. E lekola khatello ea morao ea likhase tsa ho qeta pele li kenella mohloeng oa likaroloana. Sena se fihlelleha ka li-hose tsa silicone tse (ngoe kapa ho feta) tse hokahantsoeng le DPF (haufi le lesoba) le senotlolo sa khatello ea DPF.

Ha PCM e lemoha khatello ea mokhathala e seng ho latela moetsi, kapa motlakase o tsoang ho DPF A sensor sensor e feta meeli e hlophisitsoeng, khoutu ea P2452 e tla bolokoa mme lebone la enjene ea ts'ebeletso le tla bonesa haufinyane.

Matšoao le ho tiea

Maemo ao khoutu ena e boloketsoeng ona a ka baka tšenyo ea enjene kapa sistimi ea mafura mme e lokela ho lokisoa hanghang. Matšoao a khoutu ea P2452 a ka kenyelletsa:

Tlhahlobo ea Phoso ea Enjene e Bonolo, Khoutu ea OBD P2452

Mehato e 'maloa eo u lokelang ho e latela ke ena ho hlahloba DTC ena:

Ka mor'a ho hlahloba khoutu ea P2452 ka mochine oa OBD-II, mochine o lokela ho qala ka tlhahlobo ea pono ea likarolo tsohle tsa motlakase. Sebelisa mohloli oa tlhaiso-leseling ea koloi ho fumana lintlha tse sebetsang tsa litšebeletso tsa tekheniki (TSBs). Haeba u fumana TSB e lumellanang le sebopeho le mohlala oa koloi, matšoao ao u nang le 'ona, le khoutu e bolokiloeng, e tla u thusa ho etsa tlhahlobo.

U kanna ua hloka ho fumana li-flowcharts tsa tlhahlobo, litšoantšo tsa mehala, lipono tsa sehokelo, li-pinout tsa sehokelo, libaka tsa likarolo, le mekhoa ea tlhahlobo ea likarolo / litlhaloso ho tsoa mohloling oa tlhaiso-leseling ea koloi. Lintlha tsena kaofela li tla hlokahala ho fumana khoutu e bolokiloeng ea P2452 hantle.

Kamehla u lokela ho qala ka tlhahlobo ea pono ea lithapo tsa likhoele le lihokelo. Ela hloko ka ho khetheha lithapo tse haufi le likarolo tsa mosi o chesang le likarolo tse bohale. Ka nako ena, hlahloba betri le betri, hammoho le matla a jenereithara.

Ka mor'a moo, scanner e lokela ho hokeloa 'me likhoutu tsohle tse bolokiloeng hammoho le data ea foreimi li lokela ho khutlisoa ka nepo. U ka ngola tlhahisoleseding ena fatše bakeng sa ho e sebelisa nakong e tlang. Sena se ka thusa haeba khoutu ena e fetoha ea nakoana. Ka mor'a moo, li-code li lokela ho hlakoloa, 'me koloi e lokela ho ntšoa bakeng sa teko ea teko.

Hona joale, haeba khoutu e tsosolosa hang-hang, hlahloba ho etsa bonnete ba hore mokelikeli oa ho ntša metsi o teng le hore ke oa mofuta o nepahetseng. Khoutu ena hangata e bolokoa ka lebaka la khaello ea mokelikeli oa diesel. haeba mofuta o nepahetseng oa mokelikeli oa diesel o sa fumaneheng, joale DPF e ke ke ea tsosolosa hantle, e leng se etsang hore ho be le keketseho ea khatello ea khase ea ho tsoa.

Litaelo tsa ho lekola sensor ea khatello ea DPF ka DVOM li ka fumanoa bukeng ea litšebeletso tsa moetsi. Haeba sensor e sa lumellane le litlhaloso tsa moetsi oa khanyetso, e tla bontša hore e na le phoso, kahoo e lokela ho nkeloa sebaka. Empa haeba sensor e sebetsa hantle, hlahloba li-hose tsa DPF tsa khatello ea maikutlo bakeng sa li-blockages le / kapa ho robeha. Li-hoses li tlameha ho hloekisoa le ho nkeloa sebaka ha ho hlokahala. Etsa bonnete ba hore u sebelisa li-hose tsa silicone tsa mocheso o phahameng.

Haeba sensor e le ntle 'me likhoele tsa matla li tiile, joale mohato o latelang ke ho hlahloba lipotoloho tsa tsamaiso. Li-module tsohle tse amanang le taolo li tlameha ho koaloa pele li leka ho hanyetsa le / kapa ho tsoela pele ka DVOM. Lokisa kapa fetola li-circuits tse bulehileng kapa tse khuts'oane ha ho hlokahala.

Mona ke lintlha tse ling tsa tlhahlobo eo u ka li fumanang li le molemo haholo.

Haeba u fumana hore li-hose tsa sensor ea khatello ea DPF li qhibilihile kapa li phatlohile, li lokela ho khutlisoa ka mor'a hore li nkeloe sebaka.

Ho fumana hore na koloi ea hau e na le sistimi e sebetsang ea ho nchafatsa ea DPF kapa sistimi e etsang lintho feela, ka kopo sheba Buka ea Mong'a/Tlhokomelo ea Maintenance.

Likou tsa sensor tse koetsoeng hammoho le li-tubes tse koetsoeng tsa sensor li tloaelehile.

Liphoso Tse Tloaelehileng Ha U Fumana Khoutu P2452
