See se bolela eng?
Ena ke khoutu ea phetisetso e akaretsang, e bolelang hore e sebetsa ho likoloi tsohle tsa OBD-II ho tloha ka 1996 ho ea pele. Lisebelisoa tsa koloi li ka kenyelletsa empa ha li felle feela ho Mazda, Ford, VW, Mercedes Benz, jj. Leha ho le joalo, mehato e tobileng ea ho rarolla mathata e ka fapana ho latela koloi.
Kh'outu ena ea Mathata a Tlhatlhobo (DTC) P2274 e sebetsa ho senotlolo sa "post-catalytic converter" O2 (oksijene) ho block # 1, sensor # 3. Senseara sena sa kamora katse se sebelisetsoa ho lekola katleho ea mofetoleli oa catalytic. Mosebetsi oa mofetoleli ke ho fokotsa ho tsoa ha moea. DTC ena e beha ha PCM e lemoha lets'oao le tsoang ho sensor ea O2 joalo ka ha e ts'oarehile kapa e sa nepahala.
DTC P2274 e bua ka sensor ea bobeli e tlase (kamora ho converter ea bobeli ea catalytic), sensor #3 bankeng #1. Bank #1 ke lehlakore la enjene le nang le silindara #1.
Khoutu ena e u joetsa hore lets'oao le fanoeng ke sensor e itseng ea oyxgen le khomaretse motsoako o omeletseng (ho bolelang hore ho na le moea o mongata ka har'a mokhathala).
E tloaelehileng oksijene kutlo O2: 
matšoao
Menyetla ke hore, u ke ke ua hlokomela mathata afe kapa afe a ho sebetsana le ona hobane sena ha se sensor # 1. U tla hlokomela hore Light Light Indicator Indicator (MIL) ea tla. Leha ho le joalo, maemong a mang enjene e ka sebetsa nako le nako.
Lisosa tse ka khonehang
Mabaka a DTC ena a ka kenyelletsa:
- Ho tsoa ha khase ho tsoa haufi le sensor ea O2
- Sensor ea HO2S2 e litšila kapa e fosahetseng (sensor 3)
- Bothata ba Wiring / Potoloho ea HO2S2
- Ho kenya mahala senotlolo sa HO2S2
- Khatello e fosahetseng ea mafura
- Sesebelisoa sa mafura se nang le phoso
- Setsidifatsi se dutlang sa enjene
- Phoso purge belofo solenoid
- PCM e tsoile taolong
Mekhoa ea ho hlahloba le ho lokisa
Hlahloba lithapo le likhokelo tsa mahlo bakeng sa ts'enyeho, lithapo tse koetsoeng / tse koetsoeng / tse kinked, lithakhisa tse kobehileng / tse hlephileng, lithapo tse chesitsoeng le / kapa tse tšeletseng. Lokisa kapa kenya sebaka ha ho hlokahala.
Lekola ho lutla ha metsi le ho lokisa ha ho hlokahala.
U sebelisa digital volt ohm meter (DVOM) set to ohms, test the harness connectors for resistance. Bapisa le litlhaloso tsa moetsi. Kenya sebaka kapa u lokise moo ho hlokahalang.
Haeba u na le sesebelisoa sa sesebelisoa se tsoetseng pele, se sebelise ho lekola ho bala ha sensor joalo ka ha ho bonoe ke PCM (enjene e sebelisang mocheso o tloaelehileng oa ts'ebetso ka mokhoa o koetsoeng oa loop). Sesebelisoa sa oksijene se futhumetseng se ka morao (HO2S) hangata se bona ho fetoha hoa motlakase pakeng tsa 0 le 1 volt, bakeng sa DTC ena mohlomong o tla bona matla a moea a khomaretse ho 0 V. Ho potoloha enjene ho lokela ho baka hore motlakase oa kutlo o fetohe (react).
Litharollo tse tloaelehileng ho DTC ena ke moea o tsoang, o nang le bothata ka wiring ea wiring, kapa sensor ka boeona. Haeba o nkela sensor ea O2 sebaka, reka senotlolo sa OEM (lebitso la lebitso) bakeng sa liphetho tse ntle.
Haeba o tlosa HO2S, hlahloba tšilafalo mafura, oli ea enjene le setsidifatsi.
Maikutlo a mang a rarollang mathata: Sebelisa mohlahlobi oa khatello ea mafura, lekola khatello ea mafura ho valve ea Schrader seporong sa mafura. Bapisa le lintlha tsa moetsi. Lekola sephahla sa solenoid. Lekola liente tsa mafura. Lekola litemana tse pholileng bakeng sa ho dutla.
Lipuisano tse amanang tsa DTC
- Hajoale ha ho na lihlooho tse amanang le tsona liforumong tsa rona. Romella sehlooho se secha foromong hona joale.
U hloka thuso e eketsehileng ka khoutu ea P2274?
Haeba u ntse u hloka thuso ka DTC P2274, beha potso litlatsong tse ka tlase ho sengoloa sena.
HLOKOMELA. Tlhahisoleseling ena e fanoa molemong oa tlhaiso-leseling feela. Ha ea rereloa hore e sebelisoe joalo ka khothaletso ea tokiso mme ha re na boikarabello bakeng sa ketso efe kapa efe eo u e nkang koloing efe kapa efe. Lintlha tsohle tse fumanehang sebakeng sena sa marang-rang li sirelelitsoe ka litokelo tsa bangoli.
