Mapepala a OBD-II DTC

Kuchedwa Kuyankha kwa Sensor ya O2 - Lean to Rich (Bank 2 Sensor 2)

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yofalitsira, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II (GMC, Chevrolet, Ford, Dodge, Chrysler, VW, Toyota, Honda, etc.). Ngakhale ndizachilengedwe, njira zowongolera zimatha kusiyanasiyana kutengera mtundu / mtundu.

P014B code ikasungidwa m'galimoto yokhala ndi OBD-II, zikutanthauza kuti gawo loyendetsa mphamvu ya powertrain (PCM) lapeza yankho lochedwa kuchokera ku sensa ya OSE (O2) kapena dera lachiwiri la banki ya injini . Banki 2 imazindikiritsa gulu la injini momwe silinda # 1 ikusowa.

Magalimoto oyambitsa O2 / Oxygen amamangidwa pogwiritsa ntchito zirconia sensing element yomwe imatetezedwa ndi nyumba yopangidwa ndi chitsulo. Maelekitirodi a Platinamu amagwiritsidwa ntchito kulumikiza chinthu chodziwikiratu ku mawaya omwe ali mu cholumikizira cha O2 chojambulira, chomwe chimalumikizidwa ndi PCM kudzera pa Controller Network (CAN). Chizindikiro chamagetsi chimaperekedwa kwa PCM malinga ndi kuchuluka kwa ma oxygen mu ma utsi wama injini poyerekeza ndi mpweya womwe uli mumlengalenga.

Mpweya wotulutsa utsi umalowetsa m'mizere yambiri komanso m'mizere, momwe imadutsira pa sensa ya O2 yomwe ili patsogolo pake. Mpweya wotulutsa mpweya umadutsa m'makina amtundu wa O2 (m'nyumba yachitsulo) komanso kudzera mu sensa, pomwe mpweya wozungulira umakokedwa kudzera muzitsulo zomwe zimakodwa mchipinda chaching'ono pakatikati pa sensa. Mpweya wozungulira (mchipinda) umatenthedwa ndi mpweya wotulutsa utsi, ndikupangitsa kuti ma ayoni a oksijeni apange kupsinjika (kwamphamvu).

Kupatuka pakati pa kuchuluka kwa mamolekyulu a oksijeni mumlengalenga (womwe umakokedwa pakatikati pa sensa ya O2) ndi kuchuluka kwa ma ayoni a oksijeni mu mpweya wotulutsa mpweya kumapangitsa kuti ma ion a oxygen otentha mkati mwa sensa ya O2 adumphe mwachangu pakati pa zigawo za platinamu ndi nthawi zonse. Kusintha kwamagetsi kumachitika ma ayoni a oxygen akamayenda pakati pa maelekitirodi a platinamu. Kusintha kwamagetsi kumeneku kumadziwika ndi PCM ngati kusintha kwa mpweya wa oxygen m'mipweya yotulutsa, yomwe imawonetsa kuti injini ikuyenda mwina yamafuta (mafuta ochepa) kapena olemera (mafuta ochulukirapo). Pakakhala mpweya wochuluka mu utsi (wochepa thupi), chizindikiro chamagetsi kuchokera ku sensa ya O2 chimakhala chotsika komanso chokwera ngati mpweya wocheperako ulipo mu utsi (chuma). Izi zimagwiritsidwa ntchito ndi PCM makamaka kuwerengera njira zoperekera mafuta ndi njira zoyatsira nthawi ndikuwunika momwe othandizira kusintha alili.

Ngati sensa ya O2 yomwe ikufunsidwa singagwire ntchito mwachangu komanso / kapena pafupipafupi monga zikuyembekezeredwa kwakanthawi komanso munthawi zina, kachidindo ka P014B kadzasungidwa ndipo nyali yosonyeza kusayenerera itha kubwera.

Ma DTC ena omwe amagwirizanitsidwa ndi kuchepa kwa kuyankha kwa oxygen ndi monga:

Kuuma kwa code ndi zizindikilo

Popeza chikhombo cha P014B chimatanthawuza kuti sensa ya O2 imakhalabe yochedwa kapena yosamvera kwa nthawi yayitali, iyenera kukhala yoyipa.

Zizindikiro za code iyi zitha kuphatikiza:

• Kuchepetsa mafuta
• Kuperewera kwa mphamvu zama injini
• Ma DTC ena ogwirizana atha kusungidwa.
• Nyali ya injini yothandizira idzawala posachedwa

zifukwa

Zifukwa zomwe zingakhazikitsire nambala iyi:

• Zowonongeka za O2 (s)
• Mawaya otentha, osweka, kapena osadulidwa ndi / kapena zolumikizira
• Zowonongeka zosintha zothandizira
• Kutulutsa utsi kwa injini

Njira zowunikira ndikukonzanso

Zina mwa zida zofunika zomwe ndifunika kudziwa kuti ndipeze nambala ya P014B ndi scanner yowunikira, digito volt/ohmmeter (DVOM), komanso gwero lodalirika lazidziwitso zamagalimoto (All Data DIY).

Manambala onse olakwika a injini, makina opumira molumikizira, manambala angapo amagetsi, ndi ma sensa a MAF ayenera kupezeka ndikukonzedwa asanayese kupeza nambala ya P014B. Injini yomwe sikugwira bwino ntchito ipangitsa kuti mitundu yonse yamakhodi isungidwe (ndipo ndichoncho).

Akatswiri amaphunziro nthawi zambiri amayamba ndikuwunika m'matangadza ndi zingwe zolumikizira. Timayang'ana pa zingwe zomwe zimayendetsedwa pafupi ndi mapaipi otentha ndi malo ambirimbiri, komanso omwe amayendetsedwa pafupi ndi m'mphepete mwakuthwa, monga omwe amapezeka pamapiko otentha.

Sakani ma bulletins aukadaulo (TSB) pagwero lazidziwitso zamagalimoto anu. Ngati mungapeze zomwe zikufanana ndi zizindikilo ndi zikhalidwe zomwe zafotokozedwa pagalimoto yomwe ikufunsidwayo, zikuthandizani kwambiri kuti mupeze matenda. Mndandanda wa TSB wapangidwa kuchokera kuzinthu zambiri zokonzanso bwino.

Kenako ndimakonda kulumikiza sikani ku doko loyang'anira magalimoto ndikutenga ma DTC onse osungidwa ndikuimitsa chimango. Izi zitha kukhala zothandiza ngati P014B yanu ikuwoneka kuti ndiyosakhazikika, choncho lembani nthawi ina. Tsopano chotsani manambala ndikuwona ngati P014B yasinthidwa.

Ngati codeyo yatsukidwa, yambitsani injiniyo, iyo ifike pamatenthedwe oyenera, kenako izilekeni (isafalikire paliponse kapena paki). Gwiritsani ntchito pulogalamu yolumikizira makina kuti muwone kuyika kwa sensa ya O2.

Chepetsani chiwonetsero chanu chazidziwitso kuti muphatikize zokhazokha ndipo mudzawona yankho mwachangu komanso molondola. Ngati injini ikuyenda bwino, kuwerenga kwapamwamba kwa O2 kuyenera kusinthasintha pakati pa 1 millivolt (100 volts) ndi 9 millivolts (900 volts). Ngati kusinthasintha kwama voliyumu kumachedwa pang'onopang'ono kuposa momwe amayembekezera, P014B idzasungidwa.

Mutha kulumikiza mayeso a DVOM amatsogolera ku sensa pansi ndikuwonetsa mawayilesi kuti muwunikire zenizeni zenizeni za nthawi ya O2. Muthanso kuyigwiritsa ntchito kuyesa kulimbana kwa sensa ya O2 yomwe ikufunsidwa, komanso ma voltage ndi ma sign a nthaka. Pofuna kupewa kuwonongeka kwa gawo lowongolera, siyani olamulira oyenera musanayese kuyeserera kwa dera ndi DVOM.

Zowonjezera zowonjezera:

• PCM italowa modzitsekera, ma sensa otsika a O2 sayenera kugwira ntchito pafupipafupi ngati masensa omwe akwera.
• Zosintha zotsitsika (kapena zobwezerezedwanso) zosinthira zabwino zimakhala zofooka mobwerezabwereza ndipo ziyenera kuzipewa.

Zokambirana zokhudzana ndi DTC

• Pakadali pano palibe mitu yofananira m'mabwalo athu. Tumizani mutu watsopano pamsonkhano tsopano.

Mukufuna thandizo lina ndi code p014b?

Ngati mukufunabe thandizo ndi DTC P014B, lembani funso mu ndemanga pansipa pamutuwu.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
