Idatha ye-OBD-II DTC

Ukulungisa izinga likaphethiloli lesilinda 1 kumkhawulo omkhulu

Kusho ukuthini lokhu?

Le yikhodi yezinkinga zokuxilonga i-powertrain (DTC) ejwayelekile futhi isetshenziswa kakhulu kuzo zonke izimoto zikaphethiloli ze-OBD-II. Lokhu kungafaka, kepha kungagcini lapho, izimoto ezisuka kwaLand Rover, Mazda, Jaguar, Ford, Mini, Nissan, GM, njll. Naphezu kwemvelo ejwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngonyaka wokwenziwa, ukwenziwa, imodeli nokucushwa kokudluliswa.

Ikhodi egciniwe engu-P029A isho ukuthi i-powertrain control module (PCM) ithole ingxube encike kakhulu kusilinda othile enjinini, kulokhu isilinda # 1.

I-PCM isebenzisa uhlelo lokunquma uphethiloli ukwandisa noma ukunciphisa ukulethwa kukaphethiloli njengoba kudingeka. Okokufaka inzwa yomoya-mpilo kunikeza i-PCM idatha eyidingayo ukulungisa isiqu sikaphethiloli. I-PCM isebenzisa ukuhlukahluka kwe-fuel injector pulse wide modulation (PWM) ukushintsha isilinganiso somoya / sephethiloli.

I-PCM ibala ngokuqhubekayo itrimu yesikhashana kaphethiloli. Ishintshashintsha ngokushesha futhi ingesinye sezici ezibalulekile ekubaleni ukulungiswa kwephethiloli kwesikhathi eside. Imoto ngayinye inamaphesenti amancane futhi aphezulu kakhulu we-fuel trim afakwe ku-PCM. Amapharamitha we-short term petrim trim abanzi kakhulu kunezincazelo zepharamitha ye-fuel trim yesikhathi eside.

Ukuphambuka okuncane kukhuni kukaphethiloli, okuvame ukukalwa ngamaphesenti amahle noma amabi, kuyinto ejwayelekile futhi ngeke kulondolozwe ikhodi ye-P029A. Izilungiselelo zokunquma kukaphethiloli (eziqondile noma ezingezinhle) zivame ukuba sebangeni lamaphesenti angamashumi amabili nanhlanu. Lapho lo mkhawulo ophakeme wedluliwe, lolu hlobo lwekhodi luzolondolozwa.

Lapho injini isebenza kahle futhi asikho isidingo sokwengeza noma ukwehlisa inani likaphethiloli elinikezwe isilinda ngasinye, ukulungiswa kokusetshenziswa kukaphethiloli kufanele kubonise phakathi kukaziro no-XNUMX%. Lapho i-PCM ithola isimo sokukhipha okunciphile, kuyadingeka ukukhulisa ukulethwa kukaphethiloli nokulungiswa kokusebenzisa uphethiloli kuzobonisa iphesenti elihle. Uma ukuqeda kucebe kakhulu, injini idinga uphethiloli omncane futhi ukulungiswa kokusetshenziswa kukaphethiloli kufanele kubonise iphesenti elibi.

Bheka Futhi: Konke Ofuna Ukukwazi Ngama-Fuel Trims.

Izimoto ze-OBD-II zizodinga ukusungula iphethini yecebo lesikhathi eside likaphethiloli, elizodinga imijikelezo eminingi yokushisa.

Amagrafu ama-Fuel Trim aboniswe yi-OBD-II:

Buyini ubunzima bale DTC?

Ikhodi ye-P029A kufanele ibekwe njengobucayi ngoba ingxube kaphethiloli edala ingadala umonakalo omkhulu wenjini.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P029A zingafaka:

• Ukunciphisa ukusebenza kwenjini
• Ukubambezeleka kwenjini
• Ubukhona bamakhodi we-exhaust aqediwe agciniwe
• Amakhodi wokugculisa nawo angagcinwa

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi yokunquma ka-P029A ingafaka:

• Isijova sikaphethiloli esinamaphutha
• Iphampu kaphethiloli engalungile
• Ukuvuza kwe-vacuum enjinini (kufaka phakathi ukwehluleka kwe-valve ye-EGR)
• Inzwa ye-oxygen engaphelele
• Ukungasebenzi kahle kwenzwa yokugeleza komoya (MAF) noma inzwa yomfutho womoya omningi (MAP)

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P029A?

Uma kunamakhodi ahlobene ne-MAF noma i-MAP, hlonza futhi uwakhande ngaphambi kokuzama ukuthola le khodi ye-P029A.

Ngangiqala ukuxilongwa ngokuhlolwa okujwayelekile kwendawo eningi yokungenisa injini. Ngingathanda ukugxila ekuvuzeni komshini. Kuqala ngangilalela umsindo (owakhe) wokuvuza kwesikhala. Ngangihlola wonke amapayipi nolayini bepulasitiki ukuthola imifantu noma ukuphuka. Imigqa ye-PCV ingumthombo ovamile wokuvuza komshini. Futhi hlola emaphethelweni okungena ukuze uthole izimpawu zokulimala ku-gasket. Okwesibili, bengizobheka umjovo ofanele kaphethiloli (isilinda # 1) ukuvuza kukaphethiloli. Uma umjovo umanzi ngophethiloli, sola ukuthi wehlulekile.

Uma kungekho zinkinga zomshini ezisobala egumbini lenjini, kuzodingeka amathuluzi amaningana ukuqhubeka nokuxilongwa:

1. Isithwebuli sokuhlola
2. I-Digital Volt / Ohmmeter (i-DVOM)
3. I-gauge yengcindezi ye-Fuel ene-adapters
4. Umthombo onokwethenjelwa wolwazi lwemoto

Ngemuva kwalokho ngangiyoxhuma isithwebuli ethekwini lokuhlonza imoto. Ngibuyise wonke amakhodi agciniwe futhi ngafriza idatha yohlaka ngabe sengikubhala konke ukuze kusetshenziswe esikhathini esizayo. Manje sengizosula amakhodi bese ngihlola ukushayela imoto ukubona ukuthi akhona asethwe kabusha yini.

Finyelela ukusakazwa kwedatha yesithwebuli futhi ubheke ukusebenza kwenzwa yomoya-mpilo ukuze ubone ukuthi ngabe kukhona yini ingxube yokukhipha mafutha. Ngithanda ukunciphisa ukusakazwa kwedatha ukufaka kuphela idatha efanelekile. Lokhu kunikeza izikhathi zokuphendula idatha ngokushesha nokufundwa okunembe kakhudlwana.

Uma kukhona ingxube yangempela yokuqothuka:

Isinyathelo 1

Sebenzisa igeji yokucindezela ukuhlola umfutho kaphethiloli bese uqhathanisa nedatha yomkhiqizi. Uma ingcindezi kaphethiloli ingaphakathi kokucacisiwe, iya esinyathelweni 2. Uma ingcindezi kaphethiloli ingaphansi kokucacisiwe okuncane, sebenzisa i-DVOM ukuhlola ukudluliswa kwepompo kaphethiloli namandla kagesi wepompo. Uma kukhona ugesi owamukelekayo kupompo kaphethiloli (imvamisa i-voltage yamandla ebhethri), susa isihlungi sikaphethiloli bese ubona ukuthi siminyene yini nemfucumfucu. Uma isihlungi siminyene, kufanele sishintshwe. Uma isihlungi singavinjelwe, sola ukungasebenzi kahle kwepampu kaphethiloli.

Isinyathelo 2

Finyelela kusixhumi se-injector (se-injector okukhulunywa ngaso) bese usebenzisa i-DVOM (noma isibani se-noid uma sikhona) ukuhlola amandla we-injector kanye ne-pulse yomhlabathi (owokugcina we-PCM). Uma kungatholakali ugesi kusixhumi se-injector, iya esinyathelweni 3. Uma amandla we-voltage nomhlaba kukhona, xhuma kabusha i-injector, usebenzise i-stethoscope (noma enye into elalelayo) bese ulalela ngenjini isebenza. Umsindo ozwakalayo wokuchofoza kufanele uphindwe ngezikhathi ezithile. Uma kungekho msindo noma kuphakathi nendawo, sola ukuthi umjovo wesilinda ohambisanayo awusasebenzi noma uvalekile. Noma isiphi isimo kungenzeka sidinge ukufaka esikhundleni somjovo.

Isinyathelo 3

Iningi lezinhlelo zesimanje zokujova uphethiloli zinikezela ngokutholakala njalo kwamandla kagesi ebhethri ku-injector ngayinye kaphethiloli, ne-PCM iletha ukushaya kwenhlabathi ngesikhathi esifanele ukuvala isekethe futhi kudale ukuthi uphethiloli ufuthwe kwisilinda. Sebenzisa i-DVOM ukuhlola amafyuzi wesistimu nokudluliselwa kwamandla kagesi webhethri. Shintsha amafyuzi kanye / noma udlulisele uma kunesidingo. On-umthwalo uhlelo fuse.

Ngikhohliswe yi-fuse enephutha ebonakala ilungile ngenkathi isifunda singalayishiwe (ukhiye uvuliwe / u-injini ucishiwe) bese wehluleka lapho isifunda silayishwa (ukhiye uvuliwe / usebenza ngenjini). Uma wonke amafiyuzi nokudluliswa ohlelweni kulungile futhi kungekho voltage ekhona, sebenzisa umthombo wolwazi lwemoto yakho ukuthola umkhondo wesifunda. Okungenzeka ukuthi, kuzoholela ekushintsheni kokushisa noma kumodyuli wokujova uphethiloli (uma kukhona). Lungisa uchungechunge uma kunesidingo.

Qaphela. Sebenzisa ukuqaphela lapho uhlola / ushintsha izingxenye zezinto ezisebenzisa umfutho ophakeme.
