I-P048E Exhaust Gas Pressure Control Valve Circuit Ephakeme

I-P048E Exhaust Gas Pressure Control Valve Circuit Ephakeme

Idatha ye-OBD-II DTC

Izinga lesiginali ephezulu endaweni yenzwa / yokushintsha ye-valve yokulawula ukucindezela

Kusho ukuthini lokhu?

Le Khodi Yenkinga Yokuxilongwa Kokudlulisa Okujwayelekile (DTC) isebenza kuzo zonke izimoto ze-OBD-II ezifakwe inzwa noma iswishi yokulawula ingcindezi yokukhipha ingcindezi. Lokhu kungafaka, kepha akukhawulelwe ku, i-VW, i-Audi, iToyota, njll. Naphezu kohlobo olujwayelekile, izinyathelo zokulungisa ngqo zingahluka ngokuya ngokwenziwa / imodeli.

I-Exhaust Pressure Control Valve (EPC) iyi-valve ye-solenoid esetshenziselwa ukulawula ukucindezela emuva emazingeni okushisa aphansi. Lokhu kusiza ekwandiseni ukushisa kwegumbi labagibeli, kukhuthaza ukuqala okubandayo kanye ne-windshield defrosting.

Ezimweni eziningi, imodyuli yokulawula i-powertrain (PCM) isebenzisa imininingwane evela kunzwa ye-exhaust back pressure (EBP), inzwa yokushisa yomoya (IAT), kanye nenzwa yokucindezela okuphelele (MAP) ukucacisa ukulawulwa kwe-valve. Uma i-PCM ithola inkinga nge-EPC noma i-IAT, izokhubaza i-ECP. I-ECP ivame ukutholakala ezinjinini zikadizili.

I-P048E isethwe lapho i-PCM ithola isignali yesekethe yokulawula ingcindezi ephezulu. Lokhu kuvamise ukukhombisa isekethe evulekile.

Buyini ubunzima bale DTC?

Ubunzima bale khodi bumaphakathi ukuya kobunzima. Kunconywa ukuthi ulungise le khodi ngokushesha okukhulu.

Isibonelo se-valve yokulawula ingcindezi yokukhipha:

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P048E zingafaka:

• Hlola Injini Yokukhanya
• Ukukhishwa okwengeziwe
• Ukusebenza kabi kwenjini
• Ukuqala kanzima

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi zingabandakanya:

• Exhaust igesi ingcindezi valve evulekile
• Izinkinga zokufaka izintambo
• I-PCM enamaphutha

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P048E?

Qala ngokubheka i-valve yokulawula ingcindezi yokukhipha kanye nezintambo ezihambisanayo. Bheka ukuxhumana okuxekethile, izintambo ezilimele, njll. Uma kutholakala umonakalo, lungisa lapho kudingeka khona, sula ikhodi bese ubona ukuthi iyabuya yini. Bese ubheka ama-bulletins wensizakalo yezobuchwepheshe (ama-TSB) ukuthola inkinga. Uma kungatholakali lutho, kuzodingeka uqhubekele ekuhlolweni kwesistimu ngezinyathelo.

Okulandelayo inqubo ejwayelekile njengoba ukuhlolwa kwale khodi kwehlukile emotweni kuya emotweni. Ukuze uvivinye ngokunembile isistimu, udinga ukubhekisa kutchartchch flowchart yomkhiqizi.

Hlola izintambo

Ngaphambi kokuqhubeka, udinga ukuxhumana nemidwebo yezintambo zemboni ukuthola ukuthi yiziphi izintambo. I-Autozone inikeza imihlahlandlela yokulungisa online yamahhala yezimoto eziningi kanti i-ALLDATA inikeza ukubhaliswa kwemoto eyodwa.

Hlola i-solenoid

Susa isixhumi se-solenoid. Sebenzisa i-digital multimeter set to ohms ukuhlola ukumelana kwangaphakathi kwe-solenoid. Ukuze wenze lokhu, xhuma imitha phakathi kwe-B + solenoid terminal ne-solenoid ground terminal. Qhathanisa ukumelana okulinganisiwe nemininingwane yokulungisa ifektri. Uma imitha ikhombisa ukufundwa okungaphandle kokucaciswa noma okungaphandle kwebanga (i-OL) okukhombisa isekethe evulekile, i-solenoid kufanele ishintshwe.

Hlola ohlangothini lokuhlinzekwa kwesifunda

Qinisekisa ukuthi imoto ihlezi okungenani amahora ambalwa (okungcono ubusuku bonke) nokuthi ibanda. Susa isixhumi se-solenoid. Uma ukukhanyisa imoto kuvuliwe, sebenzisa i-multimeter yedijithali esethelwe ku-DC voltage ukuze uhlole amandla e-solenoid (imvamisa engu-12 volts). Ukuze wenze lokhu, xhuma i-negative meter lead emhlabathini bese imitha ephozithivu iholele kutheminali ye-solenoid engu-B+ ohlangothini lwehhanisi lesixhumi. Uma ingekho i-voltage, xhuma imitha yokumelana (i-ignition OFF) phakathi kwetheminali ye-B+ kusixhumi se-solenoid kanye netheminali ye-voltage ye-solenoid ku-PCM. Uma ukufundwa kwemitha kuphelelwe ukubekezelelana (OL), kukhona isifunda esivulekile phakathi kwe-PCM kanye nenzwa okudingeka itholakale futhi ilungiswe. Uma isibali sifunda inani lezinombolo, kukhona ukuqhubeka.

Uma konke kuhamba kahle kuze kube manje, uzofuna ukuhlola ukuthi amandla aphuma ku-PCM. Ukuze wenze lokhu, vula i-ignition bese usetha imitha ku-voltage njalo. Xhuma indlela ephozithivu yemitha kutheminali kagesi yokunikezela nge-EPC ku-PCM, kanye nomthofu ongemuhle phansi. Uma ingekho i-voltage yereferensi evela ku-PCM, i-PCM cishe inephutha. Kodwa-ke, ama-PCM awavamile ukuhluleka, ngakho-ke kuwumqondo omuhle ukuhlola kabili umsebenzi wakho kuze kufike kulelo phuzu.

Bheka ingxenye yesifunda

Lapho ukuthungela kwemoto KUVALIWE, sebenzisa i-resistor DMM ukuhlola ukuqhubeka komhlaba. Susa isixhumi se-solenoid. Xhuma imitha phakathi kwe-solenoid ground terminal ne-chassis ground. Uma i-counter ifunda inani lezinombolo, kunokuqhubeka. Uma ukufundwa kwamamitha kungabekezeleleki (i-OL), kunesekethe evulekile phakathi kwe-PCM ne-solenoid edinga ukutholakala nokulungiswa.
