I-P048A Exhaust Gas Pressure Regulating Valve Stuck Kuvaliwe

I-P048A Exhaust Gas Pressure Regulating Valve Stuck Kuvaliwe

Idatha ye-OBD-II DTC

Ingcindezi yokukhipha igesi elawula i-valve A ivaliwe

Kusho ukuthini lokhu?

Le yikhodi yenkinga yokuxilonga yokudlulisa ejwayelekile (i-DTC) futhi isetshenziswa kakhulu ezimotweni ezinesistimu ye-OBD-II. Lokhu kungafaka, kepha kungagcini lapho, iDodge, iHonda, iChevy, iFord, iVW, njll. Naphezu kohlobo olujwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngomnyaka wemodeli, ukwakheka, imodeli nokudluliswa kokuhanjiswa.

Ikhodi egciniwe engu-P048A isho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole ukungasebenzi kahle komunye wamaphayiphu e-exhaust pressure control (regulator). I-Valve "A" ivamise ukukhombisa ukuthi inkinga iku-block yenjini equkethe isilinda # 1, kepha amadizayini ayahluka ukusuka kumkhiqizi kuye kumkhiqizi. Kulokhu, i-valve ibonakala ibhajwe endaweni evaliwe.

Izilawuli zokucindezela ugesi (ezibizwa nangokuthi i-back pressure) zisetshenziselwa izinjini zikaphethiloli nenjini kadizili. I-valve yokulawula ingcindezi yokubuyisa emuva ivame ukusebenza ngendlela efanayo nomzimba wempintsha. Isebenzisa ipuleti elilawulwa ngombane ukukhawulela ukuhamba kwamagesi aqeda njengoba kunqunywe yi-PCM. Kukhona futhi inzwa yesikhundla se-valve yokulawula ingcindezi emuva kanye / noma inzwa yokucindezela emuva emuva.

Ingcindezi yangemuva yokukhuphula igesi yokukhipha isetshenziselwa ukukhulisa ukushisa kwenjini nenjini yokupholisa ngokushesha okukhulu. Lokhu kungasiza kakhulu ezindaweni ezibandayo kakhulu.

Lokhu ukubuka konke okuyisisekelo kokusebenza kwe-outlet block pressure valve. Hlola ukucaciswa kwemoto okukhulunywa ngayo ngaphambi kokwenza noma yikuphi ukucabanga. Lapho i-PCM ithola ukuthi izinga lokushisa lomoya obandayo lingaphansi komkhawulo omncane, liqala i-valve yokukhipha igesi emuva futhi liyigcine kuze kube yilapho izinga lokushisa lomoya libuyela kokujwayelekile. Ukukhishwa komshini wokulawula ukucindezela igesi kuvame ukwenzeka kanye kuphela ngomjikelezo wokushisa. I-valve yokulawula ingcindezi emuva iklanyelwe ukupaka endaweni evulekile ngokuphelele ngemuva kokuthi ingasebenzi yi-PCM.

Uma i-PCM ithola ukuthi isilawuli se-exhaust backpress asikho endaweni oyifunayo, noma uma inzwa yokukhipha i-exhaust ibonisa ukuthi ayikho endaweni, kuzogcinwa ikhodi engu-P048A futhi isibani sesikhombisi esingasebenzi kahle (MIL) singakhanyisa.

Buyini ubunzima bale DTC?

Njengoba ingcindezi yokubuyisa emuva ingathinta imisebenzi yokulawulwa kwesimo sezulu kanye nemisebenzi yokuphatha, ikhodi egciniwe ye-P048A kufanele iphathwe ngezinga elithile lokuphuthuma.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P048A zingafaka:

• Inciphise kakhulu amandla enjini
• Ukushisa ngokweqile kwenjini noma ukuhanjiswa
• Ukuqeda kungashisa kakhulu ngemuva kokushayela.
• Amanye Amakhodi We-Exhaust Backpressure

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi ye-P048A zingafaka:

• Inzwa yokuma kwegesi yokulawula ingcindezi enephutha
• Inzwa yengcindezi yokuphuma engenaphutha
• Exhaust igesi ingcindezi valve evulekile
• Isifunda esivulekile noma esifushane ezintanjeni kwesinye sezifunda ze-valve yokulawula ingcindezi yokukhipha.

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P048A?

Ukuhlonza ikhodi ye-P048A kuzodinga umthombo othembekile wolwazi lwemoto. Amanye amathuluzi adingekayo:

1. Isithwebuli sokuhlola
2. I-Digital Volt / Ohmmeter (i-DVOM)
3. I-thermometer ye-infrared ene-laser pointer

Ngemuva kokuhlolwa ngokucophelela kwentambo nezixhumi zesistimu, thola ichweba lokuxilonga imoto. Xhuma isithwebuli ethekwini bese uthola wonke amakhodi agciniwe bese uqandisa idatha yozimele. Bhala lolu lwazi phansi ngoba lungasiza ekwenzeni ukuxilongwa.

Manje sula amakhodi bese uhlola ukushayela imoto ukubona ukuthi iP048A ibuya ngokushesha yini. Uma kunamakhodi okushisa emoyeni noma ama-engine coolant codes, hlonza futhi ulungise ngaphambi kokuzama ukuxilonga i-P048A.

Sesha ama-bulletins ezinsizakalo zobuchwepheshe (ama-TSB) asebenza emotweni okukhulunywa ngayo, amakhodi nezimpawu. Uma uthola okusebenzayo, kuzokusiza kakhulu ekuxilongweni kwakho.

• Uma kungatholakali izinkinga zensimbi noma zokuxhuma ezisobala, qala ngokuhlola isignali yamandla wegesi elindelekile ku-Exhaust Pressure Control Valve (ene-DVOM). Ungadinga ukusebenzisa isithwebuli ukulingisa izimo zokuqala ezibandayo bese wenza kusebenze uhlelo lokuqapha ingcindezi yokukhipha.
• Uma isignali efanelekile yamandla kagesi / yomhlabathi ingatholakali kusixhumi se-valve yokulawula ukucindezela, nqamula bonke abalawuli abahambisanayo bese usebenzisa i-DVOM ukuhlola ukumelana nokuqhubeka kwesekethe elilodwa. Amaketanga angahlangabezani nezidingo kufanele alungiswe noma ashintshwe.
• Uma i-voltage / umhlabathi ofanele utholakala ku-valve yokulawula ukucindezela, landela izincomo zomkhiqizi zokuhlola i-valve yokulawula ukucindezela (usebenzisa i-DVOM). Uma ukuhlolwa kwephini lokulawula ingcindezi ye-exhaust kungahambisani nemininingwane yomkhiqizi, kufanele ithathelwe indawo.
• Uma i-valve yokulawula ingcindezi ye-exhaust namasekethe kulungile, hlola inzwa yokuma kwe-valve yokulawula ingcindezi noma inzwa yengcindezi yokukhipha (uma ikhona) ukucaciswa komkhiqizi ngamunye. Miselela izinto ezinesici uma kunesidingo.

Ungasebenzisa i-thermometer ye-infrared ukuthola ukufundwa kwangempela kwezinga lokushisa kwegesi uma idatha yesithwebuli ingatholakali. Lokhu kungaba wusizo ekunqumeni ukuthi i-valve yokulawula ingcindezi yokukhipha iyasebenza yini. Ingathola futhi i-valve ebhajwe endaweni evulekile noma evaliwe.

• Ngaphansi kwezimo ezithile, isiguquli esingasebenzi kahle noma i-muffler ngeke kubangele ukuthi kugcinwe ikhodi ye-P048A.
• Amasistimu wokuqapha ingcindezi yegesi ekhishwa kakhulu asetshenziswa kakhulu kuma-turbocharged / supercharged systems.

Izingxoxo ezihlobene ze-DTC

• I-OBD II - ikhodi yephutha P048ANgineveni lakwaToyota Hiace elinomthamo wamalitha ka-2008 i-Euro-3.0 iminyaka engu-4 yokudedelwa nenjini eyi-1KD turbodiesel. Inkinga eqhubekayo yokukhishwa kwenjini yami. Isibani sesixwayiso se-exhaust gas purifier kanye nesexwayiso senjini sifika cishe ngokushesha ngemuva kokuba iveni ishiye indawo yokusebenzela kuzo zonke izimo. Ikhodi yephutha iyakhonjiswa ... 

Udinga usizo olwengeziwe ngekhodi le-P048A?

Uma usadinga usizo maqondana ne-DTC P048A, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
