Idatha ye-OBD-II DTC

Isistimu Yokulawula Umoya Engenisa Udizili - Kutholwe Ukusetshenziswa Komoya Okuphezulu

Kusho ukuthini lokhu?

Le Generic Transmission / Engine Diagnostic Trouble Code (DTC) ivamise ukusebenza kuzo zonke izinjini zikadizili ezine-OBD-II, kepha ivame kakhulu kwamanye amaloli eChevy, Dodge, Ford naseGMC.

Yize kuvamile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngemodeli yonyaka, ukwakheka, imodeli, nokucushwa kokudluliswa.

I-Diesel Intake Air Control System (i-DIAFCS) ivame ukuboshelwa kokuphindaphindwayo kokungenisa kokungena komoya. Uhlelo lwe-DIAFCS luqapha inani lokugeleza komoya okungenayo ngokushintsha isignali iye enjini elawulwa yi-powertrain control module (PCM). Imoto ivula futhi ivale i-valve mpintsha, elawula ukuhamba komoya.

I-PCM iyazi ukuthi ungakanani umoya ohlanzekile ohlungiwe ongena enjini ngokususelwa kwinzwa yedizili yokungenisa umoya womoya, owaziwa nangokuthi inzwa ye-MAF. Lapho kwenziwa uhlelo lokulawula ukuhamba komoya, i-PCM kufanele ibone ushintsho ekuhambeni komoya. Uma kungenjalo, kungahle kube khona okuthile okungahambi kahle nge-DIAFCS noma okuthile okungalungile ngenzwa ye-MAF. Lawa makhodi asethwe uma lokhu okufakwayo kungahambisani nezimo ezijwayelekile zokusebenza kwenjini ezigcinwe kwimemori ye-PCM, noma umzuzwana, njengoba kukhombisa la ma-DTC. Iphinde ibheke isignali yamandla kagesi evela ku-DIAFCS ukuthola ukuthi ilungile yini lapho kuqala ukhiye uvuliwe.

Ikhodi P02EC Isistimu Yokulawula Umoya Kadizili - Ukusetshenziswa Komoya Okuphezulu Okutholiwe kusethwa lapho isistimu yokulawula umoya engenisa injini yedizili ithola ukusetshenziswa komoya okuphezulu. Lokhu kungase kube ngenxa yomshini (ukulimala ngokomzimba ohlelweni lokulawula ngokwalo, okubangela ukwehluleka kukagesi) noma izinkinga zikagesi (i-DIAFCS motor circuit). Akufanele zishaywe indiva phakathi nesigaba sokuxazulula izinkinga, ikakhulukazi lapho kubhekwana nenkinga eyenzeka ngezikhathi ezithile.

Izinyathelo zokuxazulula inkinga zingahluka ngokuya ngomenzi, uhlobo lwenjini / iyunithi yokulawula ye-DIAFCS nemibala yocingo.

Buyini ubunzima bale DTC?

Ubunzima kuzo zonke izimo buzoba buncane. Uma izinkinga zemishini ziyimbangela, ukwehluleka okujwayelekile kuwukungenzi lutho. Uma kuwukuhluleka kukagesi, i-PCM inganxephezela ngokwanele.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P02EC zingafaka:

• Isibani sesibonakaliso sephutha sivuliwe
• Kuphela isivinini esiphansi sokungenzi lutho
• Ukukhanya kwe-elektroniki uphawu lokulawula impintsha
• Akukho Ukuvuselelwa kwesihlungi sezinhlayiyana ukuze kushiswe amadiphozithi omsi (awushisi umule ovela ku-DPF catalytic converter) - isikhalazo mayelana nokulahleka kwamandla okungenzeka

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi ye-P02EC zingabandakanya:

• Vula kumjikelezo wesignali kunjini / uhlelo lokulawula i-DIAFCS - kungenzeka
• Kufushane ukuya ku-voltage kumjikelezo wesignali ye-DIAFCS/control - Kungenzeka
• Kufushane ukuya phansi kumjikelezo wesignali kuyunithi yokulawula yenjini/DIAFCS - kungenzeka
• Ukulawulwa kwemoto/DIAFCS okungalungile - kungenzeka
• I-PCM Yehlulekile - Akwenzeki

Yiziphi ezinye zezinyathelo ze-P02EC zokuxazulula inkinga?

Iphuzu elihle lokuqala ngaso sonke isikhathi ukubheka i-Technical Service Bulletins (TSB) yemoto yakho. Inkinga yakho ingaba inkinga eyaziwayo ngokulungiswa okwenziwe ngumkhiqizi futhi kungakongela isikhathi nemali ngesikhathi sokuxilongwa.

Bese thola i-DIAFCS injini / uhlelo lokulawula emotweni yakho. Le njini / umlawuli uvame ukuboshelwa kokuphindaphindwayo kokungena kokugeleza komoya. Uma usutholakele, bheka ngokubonakalayo isixhumi nentambo. Bheka imihuzuko, izikhafu, izintambo eziveziwe, amamaki okushisa, noma ipulasitiki ebunjiwe. Nqamula isixhumi futhi uhlole ngokucophelela amatheminali (izingxenye zensimbi) ngaphakathi kwesixhumi. Bona ukuthi zibukeka zishisiwe noma zinombala oluhlaza okhombisa ukugqwala. Uma udinga ukuhlanza ama-terminals, sebenzisa i-electric contact cleaner kanye ne-plastic bristle brush. Vumela ukomisa nokufaka igrisi kagesi lapho amatheminali ethinta khona.

Uma i-mechanical code isethiwe, sebenzisa i-air intake cleaner kanye ne-rag ehlanzekile ukuze usule i-carbon deposits ngemuva kwenjini elawula i-valve mpintsha. Futha umenzeli wokuhlanza erenki bese usula noma yimaphi amadiphozi nge-rag. UNGAZE ufafaze la madiphozi enjinini ngoba angadala ukungasebenzi kahle, ukungasebenzi kahle nokuhlanza ukudla okwanele, ukulimala kwesiguquli kanye nokulimala kwenjini.

Uma unethuluzi lokuskena, sula ama-DTC kumemori futhi ubone ukuthi ikhodi ye-P02EC iyabuya yini. Uma kungenjalo, khona-ke kungenzeka ukuthi inkinga ikuxhumano.

Uma ikhodi ye-P02EC ibuya, sizodinga ukuhlola i-DIAFCS namasekhethi ayo ahlobene. Uma ukhiye IVALIWE, nqamula isixhumi sikagesi enjinini / kuyunithi yokulawula ye-DIAFCS. Xhuma intambo emnyama esuka ku-DVM uye kutheminali yaphansi ku-DIAFCS injini / isixhumi sehhanisi sokulawula. Xhuma intambo ebomvu esuka ku-DVM uye kutheminali yenjini kusixhumi sehhanisi se-DIAFCS. Vula injini, uyivale. Hlola imininingwane yomkhiqizi; I-voltmeter kufanele ifunde ama-volts angu-12. Uma kungenjalo, lungisa amandla noma intambo yaphansi noma shintsha i-PCM. Uma ungaqiniseki, hlola imininingwane yomkhiqizi ukuze uthole izinqubo eziphelele zokuhlola imoto yakho ethile.

Uma ukuhlolwa kwangaphambilini kuphumelele futhi uqhubeka nokuthola i-P02EC, cishe kuzobonisa injini ehlulekile / ukulawula kwe-DIAFCS, nakuba i-PCM ehlulekile ayikwazi ukukhishwa kuze kube yilapho kushintshwa injini / isilawuli se-DIAFCS. Uma ungenaso isiqiniseko, funa usizo kumhloli wezimoto oqeqeshiwe. Ukufaka kahle, i-PCM kufanele ihlelwe noma ilinganiselwe imoto.

Izingxoxo ezihlobene ze-DTC
