Khoutu ea mathata P2146 e bolela'ng?

Ena ke khoutu ea bothata ba tlhahlobo ea "powertrain" ea "generic powertrain" mme e sebelisoa haholo ho likoloi tsa OBD-II. Sena se ka kenyelletsa empa ha se na moeli ho likoloi tse tsoang Dodge Ram (Cummins), GMC Chevrolet (Duramax), VW, Audi, Ford (Powerstroke), Mercedes Sprinter, Peugeot, Alfa Romeo, Nissan, Saab, Mitsubishi, jj. e ka fapana ho latela selemo sa tlhahiso, sebopeho, phetisetso le phetisetso.

Liente tsa mafura ke karolo ea bohlokoa ea sistimi ea phepelo ea mafura likoloing tsa sejoale-joale.

Lisebelisoa tsa phepelo ea mafura li sebelisa likarolo tse fapaneng ho laola le ho lekola bophahamo, nako, khatello, jj. Litsamaiso li kopantsoe le ECM (Engine Control Module). Liente tsa mafura li ile tsa hlahisoa e le sebaka sa carburetor hobane liente li sebetsa hantle ebile li sebetsa hantle ho sebetsana le phepelo ea mafura. Ka lebaka leo, ba ntlafalitse moruo oa rona oa peterole, 'me baenjiniere ba nts'etsapele mekhoa e metle ea ho ntlafatsa ts'ebetso ea moralo ona.

Ka lebaka la hore atomization ea injector e laoloa ka elektroniki, phepelo ea motlakase e bohlokoa ho isa mafura ho li-cylinders. Leha ho le joalo, bothata ba ketane ena bo ka / le ho baka mathata a ho sebetsana le mathata hara likotsi / matšoao a mang a ka bang teng.

Tlhaku ea sehlopha "A" ho khoutu ena e sebelisetsoa ho khetholla phoso eo e leng oa potoloho efe. Ho tseba hore na sena se sebetsa joang koloing ea hau e ikhethang, o hloka ho sheba tlhaiso-leseling ea moetsi. Mehlala e meng ea liphapang tse nang le li-nozzle: banka ea 1, 2, jj.
