P0389 Crankshaft Position Sensor B Kusayenda Kwadongosolo

Mapepala a OBD-II DTC

Crankshaft Udindo SENSOR B Dera Kulephera

Kodi izi zikutanthauzanji?

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

Ngati galimoto yanu ili ndi nambala yosungidwa ya P0389, zikutanthauza kuti gawo loyendetsa mphamvu yamagetsi (PCM) lapeza ma voliyumu apakatikati kapena osokonekera kuchokera ku sensa yachiwiri ya crankshaft (CKP). Pamene masensa angapo a CKP amagwiritsidwa ntchito mu dongosolo la OBD II, sensa B nthawi zambiri amatchedwa sensa yachiwiri ya CKP.

Kuthamanga kwa injini (rpm) ndi crankshaft kuyang'aniridwa ndi sensa ya CKP. PCM imawerengera nthawi yoyatsira pogwiritsa ntchito crankshaft. Mukawona kuti ma camshafts amasinthasintha liwiro la theka la crankshaft, mutha kuwona chifukwa chake kuli kofunikira kwambiri kuti PCM izitha kusiyanitsa pakati pamaukoko a injini ndi utsi (RPM). Makina oyendetsa masensa a CKP amaphatikiza dera limodzi kapena angapo kuti apereke chizindikiro cholowetsera, cholozera cha 5V, ndi nthaka ya PCM.

Masensa a CKP nthawi zambiri amakhala ma electromagnetic Hall effect sensors. Nthawi zambiri amayikidwa kunja kwa injini ndikuyikidwa moyandikana (nthawi zambiri ndi masauzande ochepa chabe a inchi) kudera lamoto. Malo a injini nthawi zambiri amakhala mphete (yokhala ndi mano opangidwa bwino) yomwe imamangiriridwa kumapeto kwa crankshaft kapena yomangidwa mu crankshaft yokha. Makina ena okhala ndi masensa angapo a crankshaft amatha kugwiritsa ntchito mphete yolumikizira kumapeto kwa crankshaft ndi ina pakatikati pa crankshaft. Ena amangoyika masensa m'malo angapo mozungulira mphete imodzi ya riyakitala.

Chojambulira cha CKP chimakonzedwa kotero kuti mphete yamagetsi imadutsa mkati mwa zikwi zingapo za inchi yamaginito ake pomwe crankshaft imazungulira. Mbali zotuluka (mano) za mphete yotsekemera imatseka dera lamagetsi lamagetsi ndi sensa, ndipo zotsekera pakati pazotulutsa zimasokoneza dera. PCM imazindikira zazifupi zazifupi izi ndi zosokoneza ngati mawonekedwe amawonekedwe akuimira kusinthasintha kwamagetsi.

Zizindikiro zolowera kuchokera ku masensa a CKP zimayang'aniridwa nthawi zonse ndi PCM. Ngati magetsi olowera ku sensa ya CKP ndiotsika kwambiri kwakanthawi kwakanthawi, nambala ya P0389 idzasungidwa ndipo MIL itha kuwunikira.

Ma DTC ena a CKP Sensor B akuphatikiza P0385, P0386, P0387, ndi P0388.

Kuuma kwa code ndi zizindikilo

Palibe chiyambi choyambira chikhoza kutsagana ndi nambala yosungidwa ya P0389. Chifukwa chake, code iyi ikhoza kusankhidwa kuti ndi yayikulu.

Zizindikiro za code iyi zitha kuphatikiza:

• Injini ikukanika kuyaka
• Tachometer (ngati ili ndi zida) salembetsa RPM injini ikamayimba.
• Kuchotsa mwachangu
• Kugwiritsa ntchito injini molakwika
• Kuchepetsa mafuta

zifukwa

Zifukwa zomwe zingakhazikitsire nambala iyi:

• Cholakwika cha CKP sensor
• Tsegulani kapena zazifupi mu kachingwe ka sensa ya CKP
• Cholumikizira chowotcha kapena chothiriridwa ndi madzi pa sensa ya CKP
• Zolakwika za PCM kapena PCM zolakwika

Njira zowunikira ndikukonzanso

Ndikufuna sikani yazachipatala yokhala ndi volt / ohmmeter (DVOM) ndi oscilloscope yopangidwa musanazindikire nambala ya P0389. Mufunikanso gwero lodalirika lazidziwitso zamagalimoto monga All Data DIY.

Kuyang'ana kowoneka kwa ma waya onse okhudzana ndi makina ndi zolumikizira ndi malo abwino oyambira kuzindikira. Mayendedwe omwe ali ndi mafuta a injini, zoziziritsa kukhosi, kapena madzi owongolera magetsi ayenera kuyang'aniridwa mosamala chifukwa madzi opangidwa ndi petroleum amatha kusokoneza mawaya ndikuyambitsa zazifupi kapena mabwalo otseguka (ndi P0389 yosungidwa).

Ngati kuyang'anitsitsa kukulephera, gwirizanitsani chojambulira ndi doko lodziwitsa anthu zagalimotoyo ndikutenga ma DTC onse osungidwa ndikuwunditsa chimango. Kulemba izi kumatha kukhala kothandiza ngati P0389 ikupezeka kuti siyakhazikika. Ngati n'kotheka, yesani kuyendetsa galimotoyo kuti muwonetsetse kuti nambala yanu yachotsedwa.

Ngati P0389 yakhazikitsidwanso, pezani chojambulacho kuchokera pagwero lazidziwitso zamagalimoto ndikuyang'ana ma voliyumu pa sensa ya CKP. Voliyumu yamagetsi imagwiritsidwa ntchito poyendetsa sensa ya CKP, koma yang'anani zomwe wopanga wagalimotoyo. Dongosolo limodzi kapena angapo otulutsa komanso mbendera yapansi ipezekanso. Ngati zida zamagetsi zamagetsi ndi nthaka zikupezeka pa cholumikizira cha CKP, pitani ku gawo lotsatira.

Pogwiritsa ntchito DVOM, yesani CKP yomwe ikufunsidwa malinga ndi malingaliro a wopanga. Ngati magawo a CKP osagwirizana sakugwirizana ndi malingaliro a wopanga, akuganiza kuti ndi olakwika. Ngati kukana kwa sensa ya CKP ikufanana ndi zomwe wopanga akuchita, pitani pa gawo lotsatira.

Lumikizani mayeso oyeserera a oscilloscope pazitsogoleredwe zamagetsi ndikulowera koyipa koyenda pansi pa sensa ya CKP mutalumikiza kachipangizo kofanana ndi CKP. Sankhani magetsi oyenera pa oscilloscope ndikuyatsa. Onaninso mawonekedwe amtundu wa oscilloscope ndi injini yosasunthika, paki kapena osalowerera ndale. Samalani zamagetsi zamagetsi kapena zolakwika zamafomu. Ngati zolakwika zilizonse zapezeka, yesani zingwe ndi cholumikizira (cha CKP sensa) kuti muwone ngati vuto ndi kulumikizana kosavomerezeka kapena sensa yolakwika. Ngati pali zinyalala zochulukirapo pamphepete mwa maginito a CKP sensor, kapena ngati pali mphete yowonongeka kapena yowonongeka, izi zitha kuchititsa kuti ma voliyumu asakhalepo pamawonekedwe amawu. Ngati palibe vuto lomwe likupezeka mu mawonekedwe amawu, pitani ku gawo lotsatira.

Pezani cholumikizira cha PCM ndikuyika mayeso a oscilloscope omwe amatsogolera kulowetsa kachipangizo ka CKP ndi ma circuits apansi, motsatana. Onetsetsani mawonekedwe amawu. Ngati mtundu wamawonekedwe pafupi ndi cholumikizira cha PCM ndiosiyana ndi zomwe zimawoneka poyeserera poyeserera atalumikizidwa pafupi ndi sensa ya CKP, akuganiza kuti dera lotseguka kapena lalifupi pakati pa cholumikizira cha CKP ndi cholumikizira cha PCM. Ngati ndi zoona, sakani olamulira onse okhudzana ndikuyesa masekeli apadera ndi DVOM. Muyenera kukonza kapena kusintha ma circuits otseguka kapena otseka. PCM ikhoza kukhala yopunduka, kapena mutha kukhala ndi vuto la pulogalamu ya PCM ngati mawonekedwe amtundu wa wave ndi ofanana ndi zomwe zimawoneka pomwe oyeserera adalumikizidwa pafupi ndi sensa ya CKP.

Zowonjezera zowonjezera:

• Opanga ena amalimbikitsa kuti m'malo mwa zida za CKP ndi CMP zisinthe.
• Gwiritsani ntchito ma bulletin othandizira kuti athandizire pakuwunika

Zokambirana zokhudzana ndi DTC

• 2005 Acura adasintha lamba wa nthawi, P0389Ndinasintha lamba wanthawi ndi mpope wamadzi kuti injini ndi magetsi a VSA abwere (onse "VSA" ndi "!"). kodi P0389. Ndinayesa bwererani zoikamo, koma nthawi yomweyo tumphuka. Yang'anani zizindikiro zonse za nthawi ndipo zonse zikuwoneka bwino. Mutha kupereka malangizo abwino chonde !!!… 

Mukufuna thandizo lina ndi nambala yanu ya p0389?

Ngati mukufunabe thandizo ndi DTC P0389, 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.
