I-P0138 High Oxygen Sensor Circuit O2 (B1S2)

I-OBD-2 Incazelo Yobuchwepheshe - P0138

I-O2 Oxygen Sensor Circuit High Voltage (Bank1, iSenor2)

I-P0138 iyikhodi evamile ye-OBD-II ebonisa ukuthi inzwa ye-O2 ye-sensor ye-2 yasebhange ayinakho ukukhishwa kwe-voltage ephansi ngaphansi kwe-1V imizuzwana engaphezu kwe-1,2, okubonisa ukuntuleka komoya-mpilo kumfudlana we-exhaust.

Isho ukuthini ikhodi yephutha P0138?

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.

Inzwa ye-oxygen eshisayo (2) etholakala ngemuva kwesiguquli se-catalytic inikeza isignali yokuphumayo ehlobene nomthamo wokugcina umoya-mpilo wesiguquli se-catalytic. I-Bank 1 iyingxenye yenjini equkethe isilinda #1.

Isiginali yeHo2S 2 ayisebenzi kangako kunesignali yesensa ye-oxygen yangaphambili. Le khodi isethwe lapho i-HO2 sensor voltage yeqa i-999 mV isikhathi esingaphezu kwemizuzu engu-2 (isikhathi sincike kwimodeli. Kungaba imizuzu engama-4)

Izimpawu

Kungase kungabikho zimpawu ezibonakalayo ngaphandle kokukhanyisa kwe-MIL. Ukucindezela kukaphethiloli okukhulu okungenzeka kungagcwalisa kakhulu uhlelo.

• Injini ingase isebenze kancane ngesikhathi sokuhlolwa kwenzwa ukuze ilungise inkinga futhi ingase inyakaze noma ingashisi kahle.
• Isibani se-Check Engine sizokhanya.
• Ungase ube nezinkinga zokusebenza kwenjini kuye ngembangela yokuhluleka kwesimo esicebile.

Izizathu zephutha P0138

Ikhodi ye-P0138 ingasho ukuthi umcimbi owodwa noma eminingi yenzekile:

• Inzwa ye-O2 enephutha
• Isifunda esifushane kumandla ebhethri kusifunda sesiginali senzwa
• Umfutho omkhulu wephethiloli (akunakwenzeka)
• Imojula yokulawula injini (ECM) ibona ukuthi i-O2 sensor voltage ye-bank 2 sensor 1 inkulu kuno-1,2 V uma i-ECM iyalela uphethiloli onciphile oqondiwe kulelo bhange lenjini.
• I-ECM ithola inkinga ye-voltage ephezulu bese ikhanyisa ukukhanya kwe-Check Engine.
• I-ECM isebenzisa ezinye izinzwa ze-O2 ukuze izame ukulawula umjovo kaphethiloli ngamavelu azo.

Izixazululo ezingenzeka

Nazi ezinye izixazululo ezingaba khona:

• Miselela inzwa ye-O2
• Lungisa okufushane kuya kugesi kumjikelezo wesiginali yenzwa.

Umakhenikha uyihlonza kanjani ikhodi ye-P0138?

• Iskena idatha imisa amakhodi ozimele namadokhumenti 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 ngokulimala ngokomzimba noma ukungcoliswa koketshezi.
• Ihlola ukuvuza kwe-exhaust ngaphambi kwenzwa.
• Ilandela izivivinyo zendawo eziqondile zomkhiqizi ukuze kuxilongwe okwengeziwe.

Amaphutha Avamile Lapho Uhlonza Ikhodi P0138

Landela le mihlahlandlela elula ukuze uvimbele ukuxilonga okungalungile:

• I-Bank 2 O1 Sensor 1 ingasetshenziswa ukuxilonga i-Bank 2 O2 Sensor 1 ngokuqhathanisa ukusebenza kwazo zombili izinzwa. Ukusebenza kufanele kufane kakhulu, ngaphandle kwenzwa yesi-2 kufanele ibe ne-O2 ephansi yokufunda njengoba i-catalyst kufanele ishise uphethiloli oweqile nomoya-mpilo.
• Hlola inzwa ye-O2 ukuze uthole ukungcoliswa kukawoyela noma okupholile kunoma yikuphi ukuvuza kwenjini.
• Hlola isiguquli se-catalytic ngomonakalo noma ukuvaleka, okungase kubangele ukufundwa kwezinzwa okuyiphutha.

Ibucayi kangakanani ikhodi ye-P0138?

• I-voltage ephumayo yenzwa ye-O2 ingase ibe ngenxa yokubhujiswa kwesiguquli se-catalytic, esingabangela izinzwa ze-O2 ukuthi zikhiqize i-voltage ephezulu yokuphuma.
• I-ECM ingase ingalawuli kahle isilinganiso sikaphethiloli/somoya wenjini, okuholela ekulimaleni kwesiguquli esinamandla kanye namadiphozithi ekhabhoni amaningi enjini enamapulagi ezinhlansi ezingcolile.

Yiziphi izilungiso ezingalungisa ikhodi P0138?

• I-Bank 2 Sensor 1 O2 Sensor Replacement
• Ukulungisa noma ukushintshwa kwezintambo noma ukuxhuma kwi-O2 sensor bank 1 sensor 2
• Ukushintsha i-catalyst phambi kwenzwa
• Ukulungisa umlomo wombhobho ovuzayo

Amazwana engeziwe okufanele acatshangelwe mayelana nekhodi P0138

Isimo se-voltage ephezulu esivela kunzwa ye-O2 sibonisa ukuntuleka komoyampilo lapho kuphuma khona umoya noma ezinye izinkinga ezihlobene ezifana nomjovo kaphethiloli ovuzayo noma isiguquli se-catalytic esiphukile ngaphakathi.

Udinga usizo olwengeziwe ngekhodi le-p0138?

Uma usadinga usizo nge-DTC P0138, 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.
