I-P2629 O2 inzwa yokupompa inzwa yokulungiswa kwamanje ivulekile / i-B2S1 ivulekile

Idatha ye-OBD-II DTC

Iphampu yenzwa ye-O2 yamanje isektha / umkhawulo wesifunda ovulekile 2 inzwa evulekile, inzwa 1

Kusho ukuthini lokhu?

Le Generic Powertrain Diagnostic Trouble Code (DTC) isebenza kakhulu kuzo zonke izimoto ezihlonyelwe i-OBD-II, kufaka phakathi kodwa kungagcini kuFord, Kia, Hyundai, Mini, Audi, VW, Mercedes, BMW, njll.

I-DTC P2629 OBDII ihlotshaniswa ne-O2 pump pump sensor control circuit. Amakhodi ahlukene ayisithupha angahle asethelwe inzwa yokuqala, eyaziwa njenge-sensor ephezulu, lapho imodyuli yokulawula i-powertrain (PCM) ithola ukungasebenzi kahle kwiphampu yesilawuli samanje se-O2.

Lawa ngamakhodi P2626, P2627, P2628, P2629, P2630 ne-P2631 ngokususelwa kusiginali ethile exwayisa i-PCM ukuthi isethe ikhodi bese ivula ilambu le-Check Engine.

Ikhodi P2629 isethwe yi-PCM lapho i-O2 sensor pump current trim circuit ye-bank 2 sensor 1 ivuliwe. I-Bank 2 iyiqembu lenjini elingaqukethe isilinda #1.

Yenzani inzwa ye-O2?

Inzwa ye-O2 yenzelwe ukuqapha inani le-oxygen engashisi kugesi wokukhipha lapho ishiya injini. I-PCM isebenzisa amasiginali avela kuzinzwa ze-O2 ukuthola izinga le-oksijini kugesi wokukhipha.

Lokhu kufundwa kusetshenziselwa ukuqapha ingxube kaphethiloli. I-PCM izolungisa ingxube kaphethiloli ngokufanelekile lapho injini ikusicebi (i-oxygen encane) noma inciphile (i-oxygen eningi). Zonke izimoto ze-OBDII zinezinzwa okungenani ezimbili ze-O2, eyodwa phambi kwesiguquli se-catalytic (ngaphambi kwaso) nenye ngemuva kwayo (ezansi nomfula).

Ukucushwa kokuzikhandla okubili okuzimele kuzobandakanya izinzwa ezine ze-O2. Le khodi ye-P2629 ihlotshaniswa nezinzwa ezikhuphuka kwesiguquli se-catalytic (inzwa # 1).

Ukuqina kwekhodi nezimpawu

Ubukhulu bale khodi buphakathi, kepha buzoqhubeka uma bungalungiswa ngesikhathi esifanele. Izimpawu zekhodi yenkinga ye-P2629 zingafaka:

• Ukusebenza kabi okuqhubekayo
• Injini izosebenza ngengxube enciphile
• Injini izosebenza ngamandla aphelele.
• Isibani se-Check Engine sivuliwe
• Qeda intuthu
• Ukwanda kokusetshenziswa kukaphethiloli

Izimbangela ezijwayelekile zekhodi engu-P2629

Izizathu ezingaba khona zale khodi zingafaka:

• Inzwa ye-O2 enephutha
• Ukwakhiwa kwekhabhoni kunzwa ye-O2
• I-fuse evuthiwe (uma ikhona)
• Umfutho we-Fuel uphezulu kakhulu
• Umfutho we-Fuel uphansi kakhulu
• Vuza umshini enjinini
• Ukuvuza ngokweqile kwegesi yokukhipha
• Isixhumi esonakalisiwe noma esonakele
• Izintambo ezingalungile noma ezilimele
• I-PCM enamaphutha

Izinqubo Zokuxilonga Nezokulungisa ze-P2629

Bheka ukutholakala kwe-TSB

Isinyathelo sokuqala sokuxazulula inkinga noma iyiphi inkinga ukubuyekeza i-Technical Service Bulletins (TSBs) yemoto ethile ngonyaka, imodeli nokutshala amandla. Kwezinye izimo, lokhu kungakongela isikhathi esiningi ngokuhamba kwesikhathi ngokukukhomba endaweni efanele.

Isinyathelo sesibili ukufaka inzwa ye-O2 phezulu nomfula we-catalytic converter. Yenza ukuhlola okujulile kokubuka ukuze uhlole izintambo ezihambisanayo ukuze uthole ukukhubazeka okusobala njengokuklwebheka, imihuzuko, izintambo eziveziwe, noma izimpawu zokusha. Okulandelayo, kufanele uhlole isixhumi ukuvikeleka, ukugqwala kanye nokulimala koxhumana nabo. Njengoba injini isebenza, ukuhlola okubonakalayo kufanele kufake ukuhlonza okungase kube khona ukuvuza kwe-exhaust. Ukuhlolwa kwengcindezi yamafutha kungase kunconywe kuye ngokusetshenziswa kukaphethiloli nokusebenza kwenjini. Kufanele uthintane nedatha ethile yobuchwepheshe ukuze unqume le mfuneko.

Izinyathelo ezithuthukile

Izinyathelo ezengeziwe ziqondiswa kakhulu yimoto futhi zidinga ukuthi imishini efanelekile ukuthi yenziwe ngokunembile. Lezi zinqubo zidinga imultimeter yedijithali kanye nemibhalo eqondene nezobuchwepheshe eqondene nemoto. Izidingo zamandla kagesi zixhomeke onyakeni othile wokwenza, imodeli yemoto nenjini.

Ukuhlolwa kwe-Voltage

Lapho ingxube kaphethiloli ilinganiselwa cishe ku-14.7 kuya ku-1, okujwayelekile ezinjinini eziningi ukuze zisebenze kahle, i-gauge izofunda cishe ngama-volts angu-0.45. Inzwa ye-oxygen ivamise ukukhiqiza cishe ama-volts angama-0.9 lapho ingxube kaphethiloli icebile futhi i-oksijini engashisiwe ikhona ku-exhaust. Lapho ingxube incike, ukukhishwa kwenzwa kuzokwehla kube cishe ama-volts ayi-0.1.

Uma le nqubo ithola ukuthi awukho umthombo wamandla noma uxhumano lomhlabathi, ukuhlolwa kokuqhubeka kungadingeka ukuze kuqinisekiswe ubuqotho be-wiring. Ukuhlolwa kokuqhubeka kufanele kwenziwe njalo kususwe amandla kusuka kusekethe, futhi ukufundwa okujwayelekile kufanele kube ngu-0 ohms wokumelana ngaphandle kokuthi kuchazwe ngenye indlela kudathabheyisi. Ukuphikiswa noma ukungabikho okuqhubekayo kubonisa ukuthi i-wiring engalungile ivulekile noma iyancishiswa futhi idinga ukulungiswa noma ukushintshwa.

Ukulungisa okujwayelekile

• Ukufaka esikhundleni noma ukuhlanza inzwa ye-O2
• Ukumiselela i-fuse evuthuziwe (uma ikhona)
• Ukulungiswa kwengcindezi ye-Fuel
• Ukuqeda ukuvuza kwenjini
• Ukuqedwa kokuvuza kokukhipha
• Ukuhlanza izixhumi kusuka ku-corrosion
• Ukulungisa noma ukushintsha izintambo
• Ukukhanya noma ukufaka i-PCM esikhundleni

Ngiyethemba ukuthi imininingwane ekulesi sihloko ikusizile ukukukhomba endaweni efanele yokuxazulula inkinga nge-O2 sensor pump pump current trim loop. Le ndatshana yenzelwe ulwazi kuphela futhi imininingwane ethile yezobuchwepheshe kanye namabhulethini wensizakalo yemoto yakho kufanele kuhlale kuqala.

Izingxoxo ezihlobene ze-DTC

• BMW E2005 90i 330 - P2629Sanibonani nonke! Ngisanda kushintsha izinzwa zami ezi-2 ze-pre-cat o2 ngenxa yamakhodi athile ebhange 1. Ngemva kokushintsha yonke into ibonakala ilungile, ukuzamazama okungenzi lutho akusekho, imoto isebenza kahle. Kodwa ngesikhathi sokuhlola nge-INPA exhunyiwe, ngithole iphutha elisha ebhange 2 - P2629, bheka isithombe esingezansi: https://zapodaj….
