P222F Barometric Pressure Sensor A / B Mgwirizano

P222F Barometric Pressure Sensor A / B Mgwirizano

Mapepala a OBD-II DTC

Kapangidwe kazipangizo zamagetsi zamagetsi A / B

Kodi izi zikutanthauzanji?

Imeneyi ndi nambala yovuta yoyeza matenda (DTC) ndipo imagwiritsidwa ntchito kwambiri pamagalimoto a OBD-II. Magalimoto okhudzidwa atha kuphatikizira, koma sikuti ali ndi malire, Chevy, Mazda, Volvo, Acura, Honda, BMW, Isuzu, Mercedes Benz, Cadillac, Hyundai, Saab, Ford, GMC, ndi zina zambiri kutengera chaka. , kupanga, mtundu ndi zida zamagetsi zamagetsi.

Mitengo yambiri yama injini (ECMs) imadalira mitundu ingapo kuti injini ipatsidwe mafuta okwanira. Chiwerengero cha "mulingo woyenera" cha mpweya / mafuta chimatchedwa "stoichiometric" osakaniza: magawo 14.7 amlengalenga gawo limodzi lamafuta. Zina mwazinthu zomwe ECM imayang'anira kuti mafuta azisakanikirana ngati stoichiometric momwe angathere ndi, koma sizingokhala pazinthu izi: Kutuluka kwa mpweya, kutentha kozizira, kuthamanga kwa injini, kufunika kwa katundu, kutentha kwa mumlengalenga, ndi zina zambiri. pa mpweya wambiri komanso wozungulira. kupanikizika kuti mukwaniritse chisakanizo.

Osanenapo, machitidwewa amagwiritsa ntchito masensa ochepa kuti akwaniritse zotsatira zofanana ndi momwe mafuta amayendera / kuchita bwino. Nthawi zambiri masensa a BAP (barometric air pressure) amagwiritsidwa ntchito pomwe masensa a MAP (manifold absolute absolute) aliponso. BAPs amagwiritsidwa ntchito poyeza kuthamanga kwa mumlengalenga. Mtengowu ndi wofunikira pozindikira kusakanikirana kwamafuta, chifukwa ECM imayenera kufananiza kuthamanga kwa mumlengalenga ndi kuthamanga kwapang'onopang'ono kuti akonze bwino kusakaniza kwamafuta kuti agwirizane ndi zomwe woyendetsa amayendetsa. Kutalika ndi chinthu chofunikira kuganizira pofufuza BAP. Kutengera komwe muli, zizindikiro zanu zitha kukulirakulira kapena kusintha, makamaka ngati mumayenda pafupipafupi kumapiri.

Kalata ikaphatikizidwa pofotokoza za OBD2 DTC, nthawi zambiri imawonetsa china chake (monga mabanki osiyanasiyana, masensa, ma circuits, zolumikizira, ndi zina zambiri) m'dongosolo lomwe mukugwira. Poterepa, nditha kunena kuti ndi sensor iti yomwe mukugwira nayo. Nthawi zambiri pamakhala masensa angapo owerengera kuti athe kuwerengera molondola. Kuphatikiza apo, kulumikizana pakati pa masensa othandizira kuthandizira kasamalidwe ka mafuta, osanenapo kuti kumathandiza kupeza zolakwika mu masensa kapena mabwalo. Ndi zonsezi pamwambapa, onaninso buku lanu lazomwe mungatumizire makalata anu pagalimoto yanu.

P222F imakhazikitsidwa ndi ECM ikazindikira zovuta mu barometric pressure (BAP) sensor kapena ma A and B loop sign.

Barometric kuthamanga kachipangizo:

Kodi kuuma kwa DTC kumeneku ndi kotani?

Kulimba mtima kwake pano kudzakhala kokwera pang'ono. Powerenga izi, payenera kukhala chofulumira kuti injini iziyenda bwino. Nthawi zonse kusokonekera kungakhudze zofunikira kwambiri monga kuchuluka kwa mpweya / mafuta ndipo zikupezeka, simuyenera kuyendetsa galimoto yanu kuti injini isawonongeke. Izi zikunenedwa, ngati mwayendetsa galimoto vutolo litatha, musadandaule kwambiri, mwina muli bwino. Chotsatira chachikulu ndikuti ngati atasiyidwa osayang'aniridwa, zitha kubweretsa kuwonongeka kwa injini zamkati mtsogolo mtsogolo.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P222F zitha kuphatikizira izi:

• Kusakwanira kwa injini ndi magwiridwe antchito (kapena ochepa)
• Kusokoneza injini
• Phokoso la injini losazolowereka
• Mafuta amanunkhira
• Kuchepetsa mafuta
• Kuchepetsa chidwi cha kupindika

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi ya P222F zitha kuphatikizira izi:

• Wopunduka kapena wowonongeka wa BAP (kuthamanga kwamlengalenga)
• Cholumikizira chowonongeka kapena chowonongeka chamagetsi
• Vuto lamawaya (monga dera lotseguka, dera lalifupi, dzimbiri)
• Short dera (mkati kapena makina)
• Kulumikiza kofooka kwamagetsi
• Matenthedwe kuwonongeka
• Makina kulephera komwe kumapangitsa kuti kuwerenga kwa BAP kusinthe
• Vuto la ECM (Engine Control Module)

Ndi njira ziti zomwe zingasokoneze P222F?

Gawo loyambira # 1

Pezani sensa ya BAP (Barometric Air Pressure) pagalimoto yanu. Mwadzidzidzi, madera amtunduwu amasiyana kwambiri, chifukwa chake kusankha sensa yoyenera kuyenera kukhala kofunikira kwambiri. Mukapezeka, yang'anani kachipangizo ka BAP kuti muwonongeke. Zovuta zomwe zingakhalepo zimatha kusiyanasiyana malingana ndi malo, chifukwa chake ganizirani malo amtundu wa sensa (mwachitsanzo, madera otentha, kugwedezeka kwa injini, zinthu / zinyalala zamumsewu, ndi zina zambiri).

Gawo loyambira # 2

Onetsetsani kuti cholumikizira pa sensa pachokha chakhala moyenera kuti muwonetsetse kulumikizana kwabwino kwamagetsi. Ngati sensa ili pa injini, imatha kugwedezeka, yomwe imatha kubweretsa kulumikizana kosavomerezeka kapena kuwonongeka kwa thupi.

ZINDIKIRANI. Kumbukirani kuchotsa batri musanatseke masensa aliwonse. Kutengera ndi galimoto / dongosolo / sensa, mutha kuwononga magetsi ngati muiwala izi. Komabe, ngati mukumva kuti simuli omasuka pano kapena simudziwa zambiri zamagetsi, ndikukulimbikitsani kuti mukweze galimoto yanu kumalo okonzedweratu.

Gawo loyambira # 3

Kodi pali chilichonse chomwe chingasokoneze sensa? Izi zikhoza kukhala chifukwa cha kuwerengedwa kwachinyengo kwa barometric. Kuwerenga molondola ndikofunikira pakugwiritsa ntchito injini mwanjira zoyendetsera mafuta.

Gawo loyambira # 4

Kugwiritsa ntchito multimeter komanso kukhala ndi zida zamagetsi zofunikira pakukhudzidwa kwa mpweya. Muyenera kutulutsa cholumikizira ku sensa yokha kuti mufikire zikhomo. Mukawona zikhomo, tsatirani malangizo a wopanga kuti azindikire zomwe mukufuna ndikuzifanizira. Chilichonse chomwe sichingafotokozeredwe chiziwonetsa cholakwika. Bwezerani izi potsatira njira zoyenera kukonzanso.

Zokambirana zokhudzana ndi DTC

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

Mukufuna thandizo lina ndi nambala yanu ya P222F?

Ngati mukufunabe thandizo ndi nambala ya P222F, lembani funso m'mawu pansipa.

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.
