P2438 Secondary air injection system air flow / pressure sensor circuit, ibhange 2

Idatha ye-OBD-II DTC

Ibhange Lesekethe Lesekethe Lomoya Womoya 2

Kusho ukuthini lokhu?

Le yiGeneric Powertrain Diagnostic Trouble Code (DTC) esebenza ezimotweni eziningi ze-OBD-II (1996 nezintsha). Lokhu kungafaka, kepha kungagcini lapho, iBuick, Chevrolet, Cadillac, Lexus, Toyota, BMW, Subaru, njll. Naphezu kwemvelo ejwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngohlobo lwemodeli, ukwakheka, imodeli nokudluliswa kokudluliswa. ...

I-OBD-II DTC P2438 namakhodi ahlobene P2435, P2436, P2437 kanye ne-P2439 ahlobene nokugeleza kwesistimu yomjovo womoya wesibili/inzwa yokucindezela ibhange 2. Ibhange 2 liwuhlangothi lwenjini olungaqukethe isilinda #1.

Ibhlokhi 2 yesekethe yokungenisa umoya / yengcindezi yesistimu yomjovo womoya wesibili yakhelwe ukunciphisa inani lama-hydrocarbon wokukhipha akhishwa lapho injini iqalwa ezimweni sezulu esibandayo. IPower Control Module (PCM) isebenzisa iphampu yomoya ukuletha umoya ocindezelweyo omusha ukusheshisa ukusebenza kwe-catalyst, ukunciphisa intuthu eyingozi yokukhipha umoya. Le nqubo futhi ivumela injini ukuthi ifinyelele izinga lokushisa elijwayelekile ngokushesha. Inzwa yengcindezi yomoya isetshenziselwa ukuqapha ingcindezi yokungena ye-valve yokulawula i-solenoid valve ukuvula nokuvala i-valve emazingeni okushisa abekiwe nezingcindezi njengoba kunconyiwe ngabakhiqizi.

Lapho i-PCM ithola ukuthi i-voltage noma ukumelana kuphakame kakhulu ngaphezu kwebanga elilindelekile, i-secondary air injection system, i-bank 2, i-air flow / pressure sensor circuit izosetha ikhodi engu-P2438 futhi ukukhanya kwenjini kungakhanyisa.

Izingxenye zokuphakelwa komoya okwesibili:

Buyini ubunzima bale DTC?

Ubukhali bale khodi bungahluka kakhulu kusukela kokulingene kuya kokubi kuya ngezimpawu ezithile zenkinga. Ezinye zezimpawu zale DTC zingenza ukushayela kube yingozi ngokweqile.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P2438 zingafaka:

• Injini ingama lapho ingasebenzi khona
• Injini ngeke iqale
• Uhlelo lwesibili lokujova umoya lwenza umsindo
• Ukusebenza kabi kwenjini
• Isibani senjini yokuhlola sivuliwe

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi ye-P2438 zingafaka:

• Iphampu yomjovo womoya wesibili inesici
• Hlola i-valve engalungile.
• Iphutha lokulawula umoya i-solenoid valve
• Inzwa yengcindezi yomoya ayisebenzi
• Izintambo ezingalungile noma ezilimele
• Isixhumi esonakalisiwe noma esonakele
• I-PCM enamaphutha

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P2438?

Isinyathelo sokuqala sokuxazulula inkinga noma iyiphi inkinga ukubuyekeza i-Technical Service Bulletins (TSBs) yemoto ethile ngonyaka, imodeli nokutshala amandla. Kwezinye izimo, lokhu kungakongela isikhathi esiningi ngokuhamba kwesikhathi ngokukukhomba endaweni efanele.

Ngokuya ngemoto ethile, lesi sifunda singafaka izinto eziningana, kufaka phakathi ipompo yomjovo womoya wesibili, i-valve yokuhlola, inzwa yengcindezi, i-valve yokulawula umoya, ne-PCM. Yenza ukuhlolwa okubukekayo ukuze uhlole i-wiring ehambisanayo ukuthola ukukhubazeka okusobala njengokuklwebheka, imihuzuko, izintambo ezingenalutho, noma izindawo ezishisayo. Okulandelayo, kufanele uhlole izixhumi nokuxhuma ukuphepha, ukugqwala nokonakala koxhumana nabo. Le nqubo kufanele ifake zonke izixhumi zikagesi nokuxhuma kuzo zonke izinto, kufaka phakathi i-PCM. Thinta imininingwane yedatha yemoto yakho ukuqinisekisa ukumiswa kwesekethe bese uqinisekisa ingxenye ngayinye efakiwe kusifunda, engafaka i-fuse noma i-fuse. I-valve yokuhlola kufanele ihlolwe ukuqinisekisa ukuthi ukugeleza komoya kukuhlangothi olulodwa kuphela. Ukungena kupayipi lesibili lokujova komoya esimweni sezulu esibanda kakhulu kukhombisa ukungasebenzi kahle kwendlela yokuhlola i-valve evumela ukufiphaza okusuka kwigesi yokukhipha ukungena empompini.

Izinyathelo ezithuthukile

Izinyathelo ezengeziwe ziqondiswa kakhulu yimoto futhi zidinga ukuthi imishini efanelekile ukuthi yenziwe ngokunembile. Lezi zinqubo zidinga imultimeter yedijithali kanye nemibhalo eqondene nezobuchwepheshe eqondene nemoto.

Ukuhlolwa kwe-Voltage

Amandla wereferensi kanye nobubanzi obuvumelekile bungahluka ngokuya ngemoto ethile nokumiswa kwesekethe. Imininingwane ethile yezobuchwepheshe izobandakanya amatafula wokuxazulula inkinga nokulandelana okufanele kwezinyathelo ukukusiza wenze ukuxilongwa okunembile.

Uma le nqubo ithola ukuthi umthombo wamandla noma umhlaba ulahlekile, ukuhlolwa kokuqhubeka kungadingeka ukuhlola ubuqotho bezintambo, izixhumi, nezinye izinto. Ukuhlolwa kokuqhubeka kufanele kwenziwe njalo ngamandla angaxhunywanga kusekethe kanye nokuxhunywa kwentambo okujwayelekile nokufundwa kokuxhumeka kufanele kube ngama-0 ohms wokumelana. Ukumelana noma ukungabikho okuqhubekayo kubonisa iphutha lokuxhumeka elivulekile, elifushane, noma elonakalisiwe futhi elidinga ukulungiswa noma ukushintshwa.

Yiziphi izindlela ezijwayelekile zokulungisa le khodi?

• Ukufaka esikhundleni sephampu yomjovo womoya wesibili
• Kumiselela i-valve yesheke yendlela eyodwa enamaphutha
• Esikhundleni inzwa umfutho womoya
• Esikhundleni se-air control solenoid valve
• Ukuhlanza izixhumi kusuka ku-corrosion
• Lungisa noma buyisela izintambo ezingalungile
• Ukukhanya noma ukufaka i-PCM esikhundleni

Iphutha elijwayelekile

• Ukufaka esikhundleni sephampu yomjovo womoya wesibili lapho i-valve yokuhlola indlela eyodwa noma i-wiring embi idala ukuthi le PCM isethwe.

Ngethemba ukuthi ulwazi olukule ndatshana lukusizile wakhomba endaweni efanele ukuxazulula inkinga ye-Secondary Air Injection Air Flow / Pressure Sensor Circuit DTC, iBhange 2. Le ndatshana yenzelwe ulwazi kuphela, kanye nedatha ethile yezobuchwepheshe nama-bulletin wensiza yakho imoto kufanele ihlale njalo iza kuqala.
