Mokelikeli oa khatello ea khase ea matlafatso ea motlakase

Khoutu ea mathata P0488 e bolela'ng?

Ts'ebetso ena ea Enjene ea Transmission / Injini DTC hangata e sebetsa ho lienjine tsa dizeli tse hahiloeng kamora 2004, ho kenyeletsoa empa ho sa lekanyetsoe ho likoloi tse ling tsa Ford, Dodge, GM, Mercedes, Mitsubishi, Nissan, Suzuki le VW.

Sephahla sena se pakeng tsa mefuta e mengata ea ho noa le sefahleho sa moea, joalo ka 'mele o kopanyang. E sebelisetsoa ho etsa lephaka le lenyenyane le tla hula likhase tsa ho qeta ho kena ka bongata.

Module ea taolo ea powertrain (PCM) e joetsa phepelo ea khatello ea khase (EGR) moo e leng teng. Khoutu ena e sheba lipontšo tsa motlakase tse tsoang ho EGR throttle control valve ho bona hore na li nepahetse ho latela kenyelletso ho PCM. Khoutu ena e kanna ea beoa ka lebaka la mathata a mochini kapa a motlakase.

Mehato ea ho rarolla mathata e ka fapana ho latela moetsi, mofuta oa li-valve tsa EGR le mmala oa terata.

Matšoao

Mohlomong u ke ke ua hlokomela matšoao leha e le afe ha khoutu e hlahisoa. Khoutu e bolokoa mme lebone la enjene ea litšebeletso lea hlaha.

Matšoao a khoutu ea enjene ea P0488 a ka kenyelletsa:

• Lebone la Letšoao la ho se sebetse (MIL) le bonesitsoe
• Nako e telele ho feta e tloaelehileng ea ho nchafatsa kalafo kamora 'kalafo (ho nka nako e teletsana bakeng sa sistimi ea ho qeta ho chesa le ho chesa mosili o bokelletsoeng kahare ho mofetoleli oa DPF / catalytic)

Lisosa tsa khoutu ea P0488

Ho na le mabaka a 'maloa a ka bakang khoutu ea P0488. Lebaka le tloaelehileng haholo ke liteishene tsa sensor tsa DPFE tse koetsoeng le likanale tsa EGR. U ka boela ua fumana MAP sensor e mpe, EGR sensor, EGR valve, kapa EGR control solenoid. U ka boela ua fumana mohala o robehileng oa vacuum kapa lithapo tsa motlakase tse fosahetseng (kapa lihokelo).

Mabaka a ka bang teng a ho beha khoutu ena:

• Bula potoloho ea lets'oao lipakeng tsa belofo ea EGR throttle le PCM
• A lekgutshwanyane ho gagamalo ka ho qeta monono khase recirculation throttle pontšo potoloho.
• Nako e khuts'oane ea potoloho ea lets'oao la khase e hulang moea.
• Exhaust gas recirculation throttle valve defecte - ka hare khutšoanyane potoloho
• PCM e hlōlehileng - Ha ho bonolo

Mekhoa ea ho hlahloba le ho lokisa

Ntho e ntle eo u ka qalang ho eona kamehla ke ho lekola bulletins ea lits'ebeletso tsa tekheniki (TSB) bakeng sa koloi ea hau. Bothata ba hau e ka ba bothata bo tsebahalang ka tokiso e tsebahalang e hlahisitsoeng ke moetsi mme e ka u bolokela nako le chelete nakong ea tlhahlobo.

Ebe u fumana valve ea taolo ea `` EGR '' koloing ea hau. Sephahla sena se pakeng tsa mefuta e mengata ea ho noa le sefahleho sa moea, joalo ka 'mele o kopanyang. Hang ha e fumanoe, sheba ka likhokahano lihokelo le wiring. Batla mengoapo, scuffs, lithapo tse pepesitsoeng, matšoao a ho cha, kapa polasetiki e qhibilihisitsoeng. Tlosa lihokelo ebe u hlahloba ka hloko li-terminals (likarolo tsa tšepe) ka har'a lihokelo. Bona hore na li shebahala li chesoa kapa li na le bosootho bo botala bo bontšang ho bola.

Haeba u na le sesebelisoa sa scan, hlakola likhoutu tsa ts'oaetso ho tsoa mohopolong 'me u bone hore na khoutu ea khutla. Haeba ho se joalo, ho ka etsahala hore ebe ho na le bothata ba khokahano.

Haeba khoutu ea P0488 e khutla, re tla hloka ho lekola belofo ea EGR throttle le lisekete tse amanang le eona. Ka tloaelo, lithapo tse 3 kapa tse 4 li hokahane le sephahla sa EGR throttle. Tlosa marapo ho tsoa ho valve ea EGR. Sebelisa volt ohmmeter ea digital (DVOM) ho lekola potoloho ea lets'oao la taolo ea phepelo ea EGR (terata e khubelu ho potoloho ea lets'oao la valve, terata e ntšo mobung o motle). Haeba ho se na volt e 5 ho valve, kapa haeba u bona li-volts tse 12 ho valve, lokisa wiring ho tloha PCM ho ea ho valve, kapa mohlomong PCM e fosahetseng.
