Ena ke khoutu ea ts'oaetso ea tšoaetso ea tšoaetso (DTC) mme e sebelisoa haholo ho likoloi tse nang le sistimi ea OBD-II. Sena se ka kenyelletsa, empa ha se felle feela ho, Dodge, Honda, Chevy, Ford, VW, jj. Leha e le sebopeho sa kakaretso, mehato e nepahetseng ea ho lokisa e ka fapana ho latela selemo sa mohlala, sebopeho, phetisetso le phetiso.

Khoutu e bolokiloeng ea P048A e bolela hore module ea "powertrain control module" (PCM) e fumane ho se sebetse hantle ho e 'ngoe ea li-valve tsa khatello ea khatello ea moea (regulator). Valve "A" hangata e bontša hore bothata bo ka har'a enjene e nang le silindara # 1, empa meralo e fapana ho ea ka moetsi le moetsi. Tabeng ena, valve e bonahala e khomaretsoe sebakeng se koetsoeng.

Lisebelisoa tsa khatello ea khase ea khase (eo hape e bitsoang khatello ea morao) li sebelisoa ho li-enjini tsa peterole le disele. Sephahla sa khatello ea khatello ea mokokotlo hangata se sebetsa ka tsela e ts'oanang le 'mele o tsitsipanyang.

Kaha khatello ea mokokotlo oa mokokotlo e ka ama taolo ea maemo a leholimo le ts'ebetso ea ts'ebetso, khoutu e bolokiloeng ea P048A e lokela ho sebetsoa ka potlako.

A mang a matšoao a khoutu ke afe?

Matšoao a khoutu ea bothata ea P048A a ka kenyelletsa:

• Enjene ea enjene e fokotsehile haholo
• Ho chesa haholo ha enjene kapa phetisetso
• Ho qeta ho ka chesa haholo kamora ho khanna.
• Likhoutu tse ling tsa khatello ea khatello ea maikutlo

A mang a mabaka a tloaelehileng a khoutu ke afe?

Mabaka a khoutu ena ea P048A a ka kenyelletsa:

• Sekoli sa khatello ea khatello ea khatello ea khatello ea khatello ea khatello ea moea
• Sephahla sa khatello ea khatello ea khatello
• Ho felisa khatello ea phepelo ea khase e fosahetse

Ke mehato efe e meng ea ho rarolla bothata ba P048A?

Ho tseba khoutu ea P048A ho tla hloka mohloli o tšepahalang oa tlhaiso-leseling ea koloi. Lisebelisoa tse ling tse hlokahalang:

1. Sekena Scanner
2. Digital Volt / Ohmmeter (DVOM)
3. Infrared thermometer e nang le sesupa sa laser

Kamora ho hlahloba ka hloko wiring ea sistimi le likhokelo, fumana boema-kepe ba tlhahlobo ea koloi. Kopanya sekena koung 'me u fumane likhoutu tsohle tse bolokiloeng ebe u emisa data ea foreimi. Ngola tlhaiso-leseling ena hobane e ka u thusa ho e hlahloba.

Tlosa likhoutu joale 'me u leke koloi ho bona hore na P048A e khutla hanghang. Haeba ho na le likh'outu tsa mocheso oa moea o kenang kapa lisebelisoa tsa mocheso o pholileng oa enjene, li hlahlobe le ho li lokisa pele o leka ho fumana P048A.

Batla li-bulletins tsa lits'ebeletso tsa tekheniki (TSBs) tse sebetsang koloing eo ho buuoang ka eona, likhoutu le matšoao. Haeba u fumana e sebetsang, e kanna ea u thusa haholo tlhahlobong ea hau.

• Haeba ho sa fumanoe mathata a hlakileng a wiring kapa sehokedi, qala ka ho lekola lets'oao la motlakase le lebelletsoeng ho Exhaust Pressure Control Valve (e nang le DVOM). U kanna ua hloka ho sebelisa sekena ho etsisa maemo a ho qala a batang ebe u kenya ts'ebetsong sistimi ea khatello ea khatello.
• Haeba lets'oao le loketseng la motlakase / mobu le sa fumanoe sehokelong sa khatello ea khatello ea motlakase, hakolla balaoli bohle ba amanang le eona mme o sebelise DVOM ho leka ho hanyetsa le ho tsoela pele ha potoloho e le 'ngoe. Liketane tse sa fihlelleng litlhokahalo li tlameha ho lokisoa kapa ho nkeloa sebaka.
• Haeba motlakase / mobu o nepahetseng o fumanoa ho pompo ea khatello ea khatello, latela likhothaletso tsa moetsi bakeng sa ho etsa liteko tsa khatello ea khatello ea moea (o sebelisa DVOM). Haeba tlhahlobo ea khatello ea khatello ea khatello ea khatello e sa fihlelle litlhaloso tsa moetsi, e lokela ho nkeloa sebaka.
• Haeba sephahla sa khatello ea khatello ea motlakase le lipotoloho li lokile, leka senotlolo sa khatello ea khatello ea khatello ea khatello kapa khatello ea khatello ea khatello (haeba ho hlokahala) ho latela litlhaloso tsa moetsi. Kenya sebaka sa likarolo tse senyehileng ha ho hlokahala.

U ka sebelisa "thermometer" ea "infrared" ho fumana palo ea 'nete ea mocheso oa khase haeba "data scanner" e sa fumanehe. Sena se ka ba molemo ho tseba hore na phepelo ea khatello ea ho qeta e sebetsa joang. E ka boela ea fumana sephahla se khomaretsoeng sebakeng se bulehileng kapa se koetsoeng.
