Kusho ukuthini lokhu?
Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlome nge-OBD-II ezinenzwa yokushisa yokushisa (iSubaru, iFord, iChevy, iJeep, iNissan, iMercedes-Benz, iToyota, iDodge, njll.) D.)). Ngaphandle kohlobo olujwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngokwenziwa / imodeli.
I-catalytic converter ingenye yezingxenye ezibaluleke kakhulu zemishini yokukhipha imoto emotweni. Amagesi e-exhaust adlula kusiguquli se-catalytic lapho ukusabela kwamakhemikhali kwenzeka. Lokhu kusabela kuguqula i-carbon monoxide (CO), ama-hydrocarbon (H O) nama-nitrogen oxides (NOx) abe amanzi angenabungozi (H2O) kanye ne-carbon dioxide (CO2).
Ukusebenza kahle kokuguqula kubhekwa izinzwa ezimbili ze-oxygen; eyodwa ifakwa ngaphambi kwesiguquli, futhi enye ngemva kwayo. Ngokuqhathanisa amasignali enzwa ye-oxygen (O2), imojuli yokulawula i-powertrain (PCM) inganquma ukuthi isiguquli se-catalytic sisebenza kahle yini. Inzwa evamile ye-zirconia pre-catalyst O2 ishintsha ngokushesha ukuphuma kwayo phakathi kwama-volts angu-0.1 no-0.9. Ukufundwa kwama-volts angu-0.1 kubonisa ingxube yomoya/iphethiloli ezondile, kuyilapho ama-volts angu-0.9 ebonisa ingxube ecebile. Uma isiguquli sisebenza kahle, inzwa engezansi kufanele izinze ku-0.45 volts.
Ukusebenza kahle kwesiguquli seCatalytic kanye nokushisa kuxhunyaniswe ngokungenakuhlukaniswa. Uma isiguquli sisebenza kahle, ithempelesha yokuphuma kufanele ibe ngaphezulu kancane kuneyokushisa kokungena. Umthetho omdala wesithupha wawungu-100 degrees Fahrenheit. Kodwa-ke, izimoto eziningi zesimanje kungenzeka zingakhombisi lokhu kungafani.
Ayikho "inzwa yokushisa yokushisa" yangempela. Amakhodi achazwe kulesi sihloko enzelwe inzwa ye-oxygen. Ingxenye yekhodi yeBhange 2 ikhombisa ukuthi inkinga ikubhlokhi yesibili yenjini. Lokho wukuthi, ibhange elingafaki isilinda # 1. “Inzwa 2” isho inzwa efakwe ezansi nomfula wesiguquli sokusebenza.
I-DTC P043B isetha lapho i-PCM ithola uhla noma inkinga yokusebenza ku-Bank 2 Cat 2 Temp Sensor Circuit.
Ukuqina kwekhodi nezimpawu
Ubukhali bale khodi buphakathi. Izimpawu zekhodi yenjini engu-P043B zingafaka:
- Hlola Injini Yokukhanya
- Ukusebenza kabi kwenjini
- Ukwehla komnotho kaphethiloli
- Ukukhishwa okwengeziwe
izizathu
Izizathu ezingenzeka zale khodi ye-P043B zifaka:
- Inzwa ye-oxygen engaphelele
- Izinkinga zokufaka izintambo
- Inhlanganisela engenakulinganiswa yokukhipha umoya nophethiloli
- Izinhlelo ze-PCM / PCM ezingalungile
Izinqubo zokuxilonga nokulungisa
Qala ngokuhlola ngokubonakalayo inzwa ye-oxygen esezansi nentambo ehambisanayo. Bheka ukuxhumana okuxekethile, izintambo ezilimele, njll. Futhi hlola ukuvuza kokukhipha kokubili ngokubonakalayo nangokuzwakalayo. Ukuvuza kwe-exhaust kungadala ikhodi yamanga ye-oxygen oxygen. Uma kutholakala umonakalo, lungisa lapho kudingeka, sula ikhodi bese ubona ukuthi iyabuya yini.
Bese ubheka ama-bulletins wensizakalo yezobuchwepheshe (ama-TSBs) ngenkinga. Uma kungatholakali lutho, kuzodingeka uqhubekele ekuhlolweni kwesistimu ngezinyathelo. Okulandelayo inqubo ejwayelekile njengoba ukuhlolwa kwale khodi kwehlukile emotweni kuya emotweni. Ukuhlola ngokunembile isistimu, udinga ukubheka ku-flowchart yokuxilonga ukwakheka / imodeli ethize yemoto yakho.
Bheka amanye ama-DTC
Amakhodi we-oksijeni wezinzwa angahle asethwe ngenxa yezinkinga zokusebenza kwenjini ezibangela ukungalingani kumxube womoya / kaphethiloli. Uma kukhona amanye ama-DTC agciniwe, uzofuna ukuwasula kuqala ngaphambi kokuqhubeka nokuxilongwa kwe-oxygen sensor.
Hlola ukusebenza kwenzwa
Lokhu kwenziwa kangcono ngethuluzi lokuskena noma, okungcono, i-oscilloscope. Njengoba iningi labantu lingenakho ukufinyelela esikhaleni, sizobheka ukuxilonga inzwa ye-oxygen ngethuluzi lokuskena. Xhuma ithuluzi lokuskena ethekwini le-ODB ngaphansi kwedeshibhodi. Vula ithuluzi lokuskena bese ukhetha i-Bank 2 Sensor 2 Voltage parameter kusuka kuhlu lwedatha. Letha injini ekushiseni okusebenzayo bese ubheka imidwebo yethuluzi lokuskena.
Inzwa kufanele ifundwe kahle ngo-0.45 V ngokushintshashintsha okuncane kakhulu. Uma ingaphenduli kahle, mhlawumbe idinga ukushintshwa.
Hlola isifunda
Izinzwa ze-oksijeni zikhiqiza isignali yazo ye-voltage ebuyiselwa ku-PCM. Ngaphambi kokuqhubeka, udinga ukuxhumana nemidwebo yezintambo zemboni ukuthola ukuthi yiziphi izintambo. I-Autozone inikeza imihlahlandlela yokulungisa online yamahhala yezimoto eziningi, kanti i-ALLDATADIY inikeza ukubhaliswa kwemoto okukodwa. Ukuhlola ukuqhubeka phakathi kwenzwa ne-PCM, vula ukhiye wokumisa lapho ucime khona bese unqamula isixhumi senzwa ye-O2. Xhuma i-DMM ekumelaneni (ukuthungela kuvaliwe) phakathi kwesiginali yesiginali yenzwa ku-PCM nakucingo lwesiginali. Uma ukufundwa kwemitha kungaphandle kokubekezelelana (i-OL), kunesekethe evulekile phakathi kwe-PCM nenzwa edinga ukutholakala nokulungiswa. Uma i-counter ifunda inani lezinombolo, kunokuqhubeka.
Ngemuva kwalokho udinga ukubheka isisekelo sesekethe. Ukuze wenze lokhu, vula ukhiye we-ignition endaweni evaliwe bese unqamula isixhumi senzwa ye-O2. Xhuma i-DMM ukukala ukumelana (ukuthungela kuvaliwe) phakathi kwetheminali yomhlabathi yesixhumi senzwa ye-O2 (ohlangothini lwehanisi) nomhlaba we-chassis. Uma ukufundwa kwemitha kungaphandle kokubekezelelana (i-OL), kunesekethe evulekile ohlangothini lomhlabathi wesekethe okufanele litholwe futhi lilungiswe. Uma imitha ikhombisa inani lezinombolo, kukhona ikhefu lomhlabathi.
Ekugcineni, uzofuna ukubheka ukuthi ngabe i-PCM icubungula kahle isinali lenzwa ye-O2. Ukuze wenze lokhu, shiya zonke izixhumi zinamathiselwe bese ufaka ukuhola kwezinzwa zangemuva kusiginali yesiginali ku-PCM. Setha i-voltage ye-DMM ibe yi-DC. Ngenjini efudumele, qhathanisa ukufundwa kwamandla emitha nokufundwa kwethuluzi lokuskena. Uma zingafani, i-PCM kungenzeka ukuthi inephutha noma idinga ukwenziwa kabusha.
