Ts'ebetso ena ea Enjene ea Transmission / Injini DTC hangata e sebetsa ho lienjine tsa dizeli ho kenyelletsa, empa ho sa felle ho, likoloi tse ling tsa Ford Powerstroke, Dodge Cummins, Mercedes, Nissan le VW.
Khoutu ena e ka sebelisoa le literakeng tse nang le lienjiniere tsa dizeli le mariki a kentsoeng ke morekisi.
Sephahla se beoa ka har'a molatsoana o phallang tlaase ho bongata ba ho qeta ho hlahisa mocheso ka mokhoa oa khatello ea morao mokhatlong. Mocheso ona le / kapa khatello ea mokokotlo e ka sebelisoa ho futhumala nakong ea ho bata. E ka sebelisoa ho loants'a khatello ea lisilindara tse tsoang meqomong ea enjene ho tsoa likhase tsa ho qeta, ka hona ea liehisa enjene le koloi le eona. Sena se bohlokoa haholo ha o se hula.
Khoutu ena e supa taba ea hore lets'oao la ho kenya le tsoang ho khatello ea khatello ea khase ha le tšoane le khatello e ngata ea khatello kapa khatello e matla ea moea nakong ea ho khanna ho tloaelehileng. Sena e ka ba phoso ea mochini kapa phoso ea motlakase, ho latela moetsi oa koloi.
Mehato ea ho rarolla mathata e ka fapana ho latela moetsi, mofuta oa khatello ea khatello ea khatello le mebala ea likhoele tse tsamaisang motlakase. Sheba buka ea hau ea ho lokisa likoloi ho tseba hore na "B" ke valve efe bakeng sa nyeoe ea hau.
matšoao
Matšoao a khoutu ea enjene ea P04A2 a ka kenyelletsa:
- Lebone la Letšoao la ho se sebetse (MIL) le bonesitsoe
- Ho hloka matla
- Ha ho na brake ea enjene
- Nako e telele ho feta tloaelo ea ho futhumatsa enjene e batang
Lisosa tse ka bang teng P04A2
Hangata lebaka la ho kenya khoutu ena ke:
- Stuck ea khatello ea khatello ea mokokotlo
- Ho qeta ho fokolang
- Bula potoloho ea mobu ho ea ho sensor ea khatello ea khase
- Bula potoloho ea lets'oao pakeng tsa sensor ea khatello ea ho qeta le PCM
- Potoloho e khuts'oane ea matla a potoloho ea lets'oao la khatello ea khatello ea khase
- Sensor ea khatello ea exhaust e fosahetseng - e khuts'oane ka hare ho voltage
- Motsoako oa kutlo oa khatello ea moea o kentsoeng ka bongata
- Turbocharger e kanna ea imeloa haholo.
- Mohlomong PCM e soahlamane (ho ka etsahala)
Mekhoa ea ho hlahloba le ho lokisa
Ntho e ntle eo u ka qalang ho eona ke ho fumana Technical Service Bulletin (TSB) bakeng sa koloi ea hau. Moetsi oa likoloi a ka ba le memory memory / PCM reprogramming ho lokisa bothata bona mme ho bohlokoa hore o bo hlahlobe pele o iphumana o le tseleng e telele / e fosahetseng. PCM = Module ea taolo ea Powertrain.
Ebe u fumana "B" khatello ea khatello ea khatello koloing ea hau. Hang ha e fumanoe, sheba ka lihokelo lihokelo le wiring. Batla li-scuffs, 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 le mafome, li chesa, kapa mohlomong li le botala ha li bapisoa le 'mala oa tšepe oo u tloaetseng ho o bona. Haeba ho hlokahala hore ho hloekisoe litheipi, u ka reka mochini o hloekisang motlakase lebenkeleng lefe kapa lefe. Haeba sena se sa khonehe, fumana 91% e hohla joala le borashe bo bobebe ba polasetiki ho li hloekisa. Ebe o li omella moeeng, li nke sesebelisoa sa silicone sa dielectric (thepa e tšoanang eo ba e sebelisang bakeng sa li-bulb le li-spark plug) le ho beha moo li-terminals li kopanang teng.
Hape, haeba koloi ea hau e na le thepa, tlosa tube ea sensor e hokahanyang khatello ea khatello ea mokokotlo le mokhathala o mongata. Leka ho senya sena. Haeba hona ho sa khonehe, hona ke lebaka le ka etsahalang hore khoutu ena e hlahe.
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 e khutla, o tla hloka ho netefatsa hore matla a turbocharger a sebetsa hantle. U tla hloka sesebelisoa sa scan e ka balang khatello ea turbocharger boost. U kanna ua hloka ho lekola khatello e mengata ea ho kenella kaha sena se tla fana ka tlhaiso-leseling e tšoanang. Ela hloko khatello ka konopo, empa enjene e tinngoe. Ebe u qala enjene, khanna koloi ka lebelo le bolokehileng, ebe u potlakisa enjene ka nakoana hore e bulehe haholo, ho etsa bonnete ba hore lebelo la enjene ha le fete 2500-3000 rpm. O lokela ho hlokomela phetoho ea bonyane psi tse 18, mohlomong ho feta ho latela moetsi oa likoloi le selemo sa mohlala.
Haeba tlhahlobo ena e feta kapa o sa khone ho lekola matlafatso a turbocharger, re tla hloka ho lekola sensor le lipotoloho tse amanang. Hangata ho na le lithapo tse 3 mochining oa khatello ea ho qeta.
Tlosa marapo ho tsoa ho sensor ea khatello ea ho qeta. Sebelisa volt ohmmeter ea digital (DVOM) ho lekola potoloho ea phepelo ea motlakase ea 5V e eang ho sensor ho netefatsa hore e teng (terata e khubelu ho potoloho ea phepelo ea motlakase ea 5V, terata e ntšo mobung o motle). Haeba sensor e le li-volts tse 12 ha e lokela ho ba volts tse 5, lokisa wiring ho tloha PCM ho ea sensor ka volts e khuts'oane ho 12 kapa mohlomong PCM e fosahetseng.
Haeba sena se tloaelehile, ka DVOM, etsa bonnete ba hore u na le 5V ho potoloho ea khatello ea khatello ea khatello (terata e khubelu ho potoloho ea lets'oao la kutlo, terata e ntšo mobung o motle). Haeba ho se na li-volts tse 5 ho sensor, kapa haeba u bona li-volts tse 12 mochining, lokisa wiring ho tloha PCM ho ea ho sensor, kapa hape, mohlomong PCM e fosahetseng.
Haeba ho tloaelehile, etsa bonnete ba hore sensor ea khatello ea ho qeta e thehiloe hantle. Hokela lebone la teko ho betri ea 12 V (sesebelisoa se khubelu) ebe o ama karolo e 'ngoe ea lebone la liteko ho potoloho ea lefatše e lebisang mobung oa khatello ea khatello ea khase. Haeba lebone la teko le sa khanye, e bonts'a potoloho e fosahetseng. Haeba e tla, ts'oara marapo a wiring a eang ho sensor ea khatello ea ho qeta ho bona hore na lebone la liteko le a panya, e leng se bontšang khokahano e kenang.
Haeba liteko tsohle tse fetileng li fetile 'me u ntse u fumana khoutu ea P04A2, e kanna ea supa senotlolo sa khatello ea khatello, le ha sephahla se koetsoeng sa khatello ea mokokotlo se koetsoe kapa PCM e hlolehileng e ke ke ea qheleloa ka thoko ho fihlela senotlolo se tla nkeloa sebaka.
