I-P0151 Izinga lesiginali ephansi kusifunda se-oxygen sensor B2S2

Idatha ye-P0151

I-P0151 - I-O2 Sensor Circuit Low Voltage (Inzwa yeBhange 2 1)

Isho ukuthini ikhodi yenkinga P0151?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Ngokuyinhloko okufana ne-P0136, P0137, ne-P0131, ikhodi ye-P0151 ibhekisa kunzwa yokuqala ye-oxygen ebhange 2. I-P0151 isho ukuthi i-O2 oxygen sensor voltage ihlale iphansi isikhathi esingaphezu kwemizuzu emi-2.

I-ECM ihumusha lokhu njengesimo samandla aphansi bese ibeka i-MIL. I-Bank 2 Sensor 1 itholakala ngaphambi kwesiguquli se-catalytic.

Izimpawu

Umshayeli kungenzeka angaboni zimpawu ezibonakalayo ngaphandle kwe-MIL (Check Engine / Service Engine Soon).

• I-voltage yenzwa ephansi ye-O2 ibangela i-ECM ukuthi inothe ingxube enjinini.
• Isibani se-Check Engine sizokhanya.
• Ungase ube nokuvuza kwe-exhaust kufika noma eduze kwenzwa ye-O2 okukhulunywa ngayo. Ukuvuza kwe-exhaust kungaba kukhudlwana uma injini ibanda futhi yehle njengoba injini ifudumala.

Izimbangela zephutha P0151

Ikhodi ye-P0151 ingasho ukuthi umcimbi owodwa noma eminingi yenzekile:

• Imojula yokulawula injini (ECM) ibona ukuthi i-O2 sensor voltage ye-bank 1 sensor 2 ingaphansi kuka-0,21 V lapho i-ECM iyale uphethiloli ocebile kulelo bhange.
• I-exhaust ivuza ngaphambi kokuba inzwa yethule i-oxygen eyengeziwe ekukhishweni, okubangela inzwa ye-O2 ukuthi ifunde umoya-mpilo oweqile kanye ne-ECM egijima ekucebiseni.
• Inzwa ye-oxygen eyiphutha o2
• Isifunda esifushane kumandla wesifunda wesiginali O2
• Ukumelana okuphezulu noma ukuvula isekethe yesiginali ye-O2

Izixazululo ezingenzeka

• Lungisa ukumelana okufishane, okuvulekile, noma okuphezulu kwisekethe yesiginali ye-o2.
• Ukushintsha Inzwa ye-O2 Yenzwa Yebhange 1 2 Uma Konke Ukuhlola Kukhomba Inzwa Engalungile
• Ukulungisa noma ukushintshwa kwezintambo noma ukuxhuma kwi-O2 sensor bank 2 sensor 1
• Ukuqedwa kokuvuza kwegesi ephumayo phambi kwenzwa, ngenxa yokuthi i-oksijini eyengeziwe ingena emagesi okukhipha.

Umakhenikha uyihlonza kanjani ikhodi ye-P0151?

• Iskena amakhodi namadokhumenti, ithwebule idatha yozimele, bese isula amakhodi ukuze kuqinisekiswe ukwehluleka
• Iqapha idatha yenzwa ye-O2 ukuze ibone ukuthi ingabe i-voltage ishintsha phakathi kokuphansi nokuphezulu ngenani eliphezulu uma kuqhathaniswa nezinye izinzwa.
• Ihlola izintambo zenzwa ye-O2 kanye noxhumo lwamahanisi ukugqwala ekuxhumekeni.
• Ihlola inzwa ye-O2 ngomonakalo obonakalayo noma ukungcoliswa koketshezi; ilungisa noma yikuphi ukuvuza ngaphambi kokufaka inzwa ye-O2
• Ihlola ukuvuza kwe-exhaust ngaphambi kwenzwa, ilungise ukuvuza, futhi ihlola kabusha inzwa.

Amaphutha Avamile Lapho Uhlonza Ikhodi P0151

Landela le mihlahlandlela elula ukuze uvimbele ukuxilonga okungalungile:

• Lungisa noma yikuphi ukuvuza kwe-exhaust enhla nenzwa ukuze uvimbele umoya-mpilo owedlulele ukuthi ungangeni ku-exhaust stream okubangela ukufundwa kwamandla kagesi aphansi.
• Lungisa ukuvuza kukawoyela noma okupholisayo okungangcolisa noma kuvale izinzwa.

Ibucayi kangakanani ikhodi ye-P0151?

• I-voltage ephumayo yenzwa ye-O2 ingase ibe ngenxa yokuvuza kwe-exhaust, okubangela ukuthi izinzwa ze-O2 zikhiqize ama-voltage okukhiphayo aphansi abonisa umoya-mpilo oweqile kumfudlana we-exhaust.
• I-ECM ayikwazi ukulawula isilinganiso sikaphethiloli/somoya enjinini uma inzwa ye-O2 inesici. Lokhu kuzodala ukonga kukaphethiloli okungekuhle futhi uphethiloli oweqile uzongcolisa ama-spark plug ngokuhamba kwesikhathi.

Amazwana engeziwe okufanele acatshangelwe mayelana nekhodi P0151

Isekhethi yenzwa ye-O2 ye-bank 1 sensor 2 isetshenziselwa ukunikeza impendulo ye-voltage ku-ECM ebonisa ukuthi ingakanani i-oxygen ekhona ku-exhaust stream ukusiza injini ilawule isilinganiso somoya/samafutha. Isimo se-voltage ephansi sibonisa ukweqisa komoya-mpilo kumagesi aphumayo.

Udinga usizo olwengeziwe ngekhodi le-p0151?

Uma usadinga usizo nge-DTC P0151, 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.
