P02E2 Inkomba ephansi yesekethe yokulawula ukuhamba komoya lapho kufakwa injini kadizili

Idatha ye-OBD-II DTC

Izinga lesignali eliphansi kumjikelezo wokulawula wokugeleza komoya ekuthatheni injini yedizili

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 P02E2 I-Diesel Intake Air Control Circuit Low isethwe lapho isimo sikagesi esiphansi sitholwa ohlelweni lokulawula umoya ongenisa udizili. Isethwa lapho i-voltage ku-ECM ihlala ingaphansi kwezinga elimisiwe (ngokuvamile lingaphansi kuka-0.3 V) isikhathi eside kakhulu. Le khodi ivame ukubhekwa njengenkinga yesekethe kagesi.

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-P02E2 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-P02E2 zingafaka:

• Kufushane ukuya phansi kumjikelezo wesignali kuyunithi yokulawula yenjini/DIAFCS - kungenzeka
• Ukulawula Okungalungile Kwezimoto/I-DIAFCS - Kungenzeka
• I-PCM Yehlulekile - Akwenzeki

Yiziphi ezinye zezinyathelo ze-P02E2 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-DTCs kwimemori bese ubona ukuthi iyabuya yini i-P02E2. Uma lokhu kungenjalo, kungenzeka ukuthi kunenkinga yokuxhuma.

Uma ikhodi ye-P02E2 ibuya, kuzodingeka sihlole i-DIAFCS namasekethe ayo ahlobene nayo. Ngokucisha ukhiye, nqamula isixhumi sikagesi enjini / iyunithi yokulawula ye-DIAFCS. Xhuma ukuhola okumnyama kusuka ku-DVM kuye ekugcineni komhlaba kusixhumi se-DIAFCS injini / isilawuli se-harness. Xhuma ukuhola okubomvu kwe-DVM kusikhungo sokugcina injini kusixhumi se-harness ye-DIAFCS. Vula ukhiye, injini icishiwe. Bheka imininingwane yomkhiqizi; i-voltmeter kufanele ifunde ama-volts ayi-12. Uma kungenjalo, lungisa ugesi noma ucingo lwaphansi noma ubeke i-PCM esikhundleni. Uma ungaqiniseki, hlola imininingwane yomkhiqizi ngezinqubo ezigcwele zokuhlola emotweni yakho ethile.

Uma isivivinyo sangaphambilini sidlulile futhi uqhubeka nokuthola i-P02E2, kungenzeka ikhombise ukulawulwa kwezimoto / kwe-DIAFCS, yize i-PCM ehlulekile ingakhishelwa ngaphandle kuze kushintshwe imoto / ukulawula kwe-DIAFCS. Uma ungaqiniseki, funa usizo kudokotela ohlola izimoto oqeqeshiwe. Ukufaka kahle, i-PCM kufanele ihlelwe noma ilinganiselwe imoto.
