I-P0042 B1S3 Isifunda Esilawulayo Sokushisa Kwe-oksijeni

Idatha ye-OBD-II DTC

Isekethe Yokulawula Isifudumezi se-Oxygen (Ibhange 2, Inzwa 1)

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezifakiwe ze-OBD-II, kufaka phakathi kepha kungagcini kuVW Volkswagen, Audi, Mazda, Ford, Chevy, njll. kuya ngomkhiqizo / imodeli.

Ezimotweni ezijova uphethiloli, izinzwa ezishisayo zomoya-mpilo ziyasetshenziswa ngaphambi nangemva kokuguqula okukhomba ukuthola okuqukethwe komoya-mpilo ohlelweni lokukhipha. Le mpendulo isetshenziselwa ukulungisa uhlelo lukaphethiloli ukugcina isilinganiso esifanele esingu-14.7: 1 somoya / sephethiloli.

Izinzwa ze-oksijeni zisebenzisa i-loop evuthayo ukufudumeza inzwa ukuthola impendulo esheshayo. Inzwa ye-oxygen ingasebenzisa izintambo ezintathu noma ezine ngokuya ngemoto, ezimbili zivamise ukusetshenziselwa ukuphendula inzwa kumodyuli yokulawula i-powertrain module (PCM) / module control engine (ECM), kanti ezinye izintambo ezenzelwe iheater ukunika amandla isifunda esivuthayo . ... Izinzwa ezinezintambo ezintathu zivame ukufakwa ngaphansi kohlelo lokukhipha, kuyilapho izinzwa ezine-wire ezinezintambo ezihlukile zomhlabathi.

Ikhodi ye-P0042 isho inzwa yesithathu ngemuva kwenjini esebhange 1, etholakala ohlangothini lwenjini eno-cylinder # 1. Isifunda se-heater singanikwa amandla noma sisuselwe ku-PCM / ECM noma komunye umthombo ongalawulwa yi-PCM / ECM.

Qaphela. Qaphela ukuthi ungasebenzi ohlelweni lokuqeda ukukhanda olusanda kusetshenziswa ngoba lungashisa kakhulu.

izimpawu

Izimpawu ze-DTC P0042 zifaka phakathi ilambu le-Malfunction Indicator (MIL). Cishe ngeke uqaphele noma yiziphi ezinye izimpawu ezihambisana nokungasebenzi kahle kwesifunda njengoba kusebenza umzuzwana lapho imoto iqala khona. Le sensor nayo itholakala ngemuva kwesiguquli se-catalytic, ngakho-ke ayithinti isilinganiso sokufaka somoya / uphethiloli ku-PCM / ECM; isetshenziswa kakhulu ukuvivinya ukusebenza kahle kweziguquli ezisebenzisayo.

izizathu

Izimbangela ezingaba khona ze-DTC P0042 zingafaka:

• Isifunda esivulekile ngaphakathi kwenzwa yomoya-mpilo noma amandla avulekile noma ucingo lwaphansi ebhange lenzwa ye-oxygen 1, No. 3
• Isistimu yokukhipha isisekelo ebekiwe ingahle igqame noma iphuke.
• I-PCM / ECM noma i-oxygen sensor heater circuit wiring ayisebenzi

Izixazululo ezingenzeka

Hlola i-wiring wiring wiring yomonakalo noma i-wiring evulekile ku-sensor.

Nqamula inzwa ye-oksijini futhi une-digital volt ohm meter (i-DVOM) esethwe esikalini se-ohms, hlola ukumelana kwesekhethi yeheater usebenzisa umdwebo wiring njengesethenjwa. Kufanele kube nokumelana okuthile esifundeni se-heater ngaphakathi kwenzwa, ukumelana ngokweqile noma ukweqa inani lomkhawulo kuzokhombisa ukuvuleka engxenyeni eshubile yesekethe, futhi inzwa ye-oxygen kufanele ishintshwe.

Bheka ucingo lwangaphansi kwesixhumi bese ubheka ukumelana phakathi komhlaba owaziwayo nesixhumi senzwa yomoya-mpilo.

Bheka intambo yokuhambisa ugesi kusixhumi ne-DVOM esethwe kumandla kagesi ahlala njalo ngocingo oluhle ocingweni lokuphakelwa kukagesi kanye nocingo olubi endaweni eyaziwayo ukuqinisekisa ukuthi kukhona amandla enzwa ye-oxygen. Uma engekho amandla kusixhumi ngesikhathi sokuqala kwezimoto sokuqala (ukuqala okubandayo), kungahle kube nenkinga ngesekethe yokunikezwa kwamandla kwe-oxygen sensor noma i-PCM uqobo.

Izingxoxo ezihlobene ze-DTC

Udinga usizo olwengeziwe ngekhodi le-p0042?

Uma usadinga usizo nge-DTC P0042, 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.
