I-P222F Barometric Pressure Sensor A / B Correlation

I-P222F Barometric Pressure Sensor A / B Correlation

Idatha ye-OBD-II DTC

Ukulungiswa kwenzwa yokucindezela kwe-Barometric A / B

Kusho ukuthini lokhu?

Le yikhodi enenkinga yokuxilonga i-powertrain (DTC) ejwayelekile futhi isetshenziswa kakhulu ezimotweni ze-OBD-II. Izimoto ezithintekile zingafaka, kepha azikhawulelwanga, eChevy, Mazda, Volvo, Acura, Honda, BMW, Isuzu, Mercedes Benz, Cadillac, Hyundai, Saab, Ford, GMC, njll kuye ngonyaka. , yenza, imodeli kanye nemishini yeyunithi yamandla.

Amayunithi amaningi wokulawula izinjini (ama-ECM) ancike enanini elihlukile lezilinganiso ukuze inikeze ngokunembile injini isilinganiso esikahle somoya-uphethiloli. Isilinganiso “esihle” somoya / uphethiloli sibizwa ngengxube ye- “stoichiometric”: izingxenye eziyi-14.7 zomoya ziye engxenyeni eyodwa kaphethiloli. Amanye amanani i-ECM ewalawulayo ukugcina ingxube kaphethiloli njenge-stoichiometric ngangokunokwenzeka, kepha ayikhawulelwe kulokhu: ukuhamba komoya, izinga lokushisa okupholisayo, isivinini senjini, ukufunwa komthwalo, izinga lokushisa lomkhathi, njll. emoyeni odlayo naphakathi. ingcindezi yokwandisa ingxube.

Ingasaphathwa eyokuthi, lawa masistimu asebenzisa izinzwa ezimbalwa ukuze athole imiphumela efanayo mayelana nokuphathwa/ukusebenza kahle kukaphethiloli. Ngokuvamile izinzwa ze-BAP (barometric air pressure) zisetshenziswa uma izinzwa ze-MAP (manifold absolute absolute) zikhona nazo. Ama-BAP asetshenziselwa ukukala umfutho womkhathi. Leli nani libalulekile ekunqumeni izingxube zikaphethiloli, njengoba i-ECM idinga ukuqhathanisa umfutho womkhathi nokucindezela okuningana okukhiphayo ukuze kulungiswe kahle ingxube kaphethiloli nezidingo zokushayela zomshayeli. Ubude buyinto ebalulekile okufanele icatshangelwe lapho uxilonga i-BAP. Kuya ngendawo okuyo, izimpawu zakho zingase zibe zimbi kakhulu noma zibe ngcono, ikakhulukazi uma uhamba njalo ezindaweni ezinezintaba.

Lapho incwadi ifakwa encazelweni ye-OBD2 DTC, ezimweni eziningi izokhombisa okuthile okuqondile (njengamabhange ahlukahlukene, izinzwa, amasekethe, izixhumi, njll.) Ohlelweni osebenza kulo. Kulokhu, ngingasho ukunquma ukuthi iyiphi inzwa osebenza nayo. Imvamisa kuzoba nezinzwa eziningi ze-barometric zokunikeza ukufundwa okunembile. Ngaphezu kwalokho, ukuhlangana phakathi kwezinzwa ukusiza ekuphatheni uphethiloli, kungasaphathwa ukuthi kuyasiza ukuthola amaphutha ezinzwa noma kumasekethe. Ngakho konke okungenhla, bheka ibhukwana lakho lesevisi ukuthola imininingwane ethile yencwadi yemoto yakho ethile.

I-P222F isethwe yi-ECM lapho ithola ukungajwayelekile kunzwa ye-barometric pressure (BAP) noma amasiginali ayo we-A no-B.

Inzwa yengcindezi ye-Barometric:

Buyini ubunzima bale DTC?

Ubunzima lapha buzophakama ngokulingene. Ngenkathi ufunda lokhu, kufanele kube nokuphuthuma okuthile ukugcina injini isebenza kahle. Noma nini lapho ukungasebenzi kahle kungathinta ngqo amanani abaluleke kakhulu njenge-air / fuel ratio futhi akhona ngentshiseko, akufanele ushayele imoto yakho ukuvimbela ukulimala kwenjini. Uma kushiwo lokho, uma ushayele imoto ngemuva kokuthi iphutha lisebenzile, ungakhathazeki kakhulu, mhlawumbe ulungile. Ukuthatha okukhulu ukuthi uma kushiywe kungagadiwe, kungaholela ekulimaleni kwenjini kwangaphakathi okubizayo esikhathini esizayo.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P222F zingafaka:

• Amandla enjini nokusebenza okunganele (noma kukhawuliwe)
• Ukudubula kabi kwenjini
• Umsindo wenjini ongajwayelekile
• Iphunga le-Fuel
• Ukwehla komnotho kaphethiloli
• Ukunciphisa ukuzwela kwe-throttle

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi ye-P222F zingafaka:

• Inzwa ye-BAP enephutha noma eyonakele (ingcindezi yasemkhathini)
• Isixhumi sikagesi esinamaphutha noma esonakele
• Inkinga yezintambo (isb. Isekethe evulekile, isifunda esifushane, ukugqwala)
• Isifunda esifushane (ngaphakathi noma ngomshini)
• Uxhumano lukagesi olubuthakathaka
• Ukulimala okushisayo
• Ukwehluleka kwemishini okwenza ukuthi ukufundwa kwe-BAP kushintshe
• Inkinga ye-ECM (Engine Control Module)

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P222F?

Isinyathelo esiyisisekelo # 1

Thola inzwa ye-BAP (Barometric Air Pressure) emotweni yakho ethize. Ngokwami ​​ukubona, izindawo zalezi zinzwa ziyahlukahluka kakhulu, ngakho-ke ukukhetha inzwa efanele kufanele kubaluleke kakhulu. Uma usutholakele, hlola inzwa ye-BAP nganoma yikuphi ukulimala komzimba. Izinkinga ezingaba khona zingahluka ngendawo, ngakho-ke bhekisisa imvelo yenzwa (isb. Izindawo ezinamazinga okushisa aphezulu, ukudlidlizela kwenjini, izakhi / imfucumfucu yomgwaqo, njll.).

Isinyathelo esiyisisekelo # 2

Qiniseka ukuthi isixhumi senzwa sihleli kahle ukuqinisekisa ukuxhumana okuhle kagesi. Uma inzwa itholakala enjinini, ingaba ngaphansi kokudlidliza, okungadala ukuxhumana okuxekethile noma ukulimala ngokomzimba.

QAPHELA. Khumbula ukunqamula ibhethri ngaphambi kokunqamula noma yiziphi izinzwa. Ngokuya ngemoto / isistimu / inzwa, ungadala umonakalo kuma-surge kagesi uma ukhohlwa lesi sinyathelo. Kodwa-ke, uma uzizwa ungakhululekile lapha noma unolwazi olulinganiselwe lobunjiniyela kagesi, ngincoma ukuthi udonse / uthathe imoto yakho uyise endaweni yokulungisa eyaziwayo.

Isinyathelo esiyisisekelo # 3

Ngabe kukhona okuphazamisa inzwa? Lokhu kungaba imbangela yokufundwa kwengcindezi yamanga ye-barometric. Ukufundwa okunembile kuhambisana nokusebenza kahle kwezinjini kulezi zinhlelo zokuphathwa kukaphethiloli.

Isinyathelo esiyisisekelo # 4

Usebenzisa i-multimeter futhi uhlome ngamanani kagesi adingekayo we-barometric pressure pressure sensor. Uzodinga ukunqamula isixhumi kunzwa uqobo ukufinyelela izikhonkwane. Lapho usubonile izikhonkwane, landela imiyalo yomkhiqizi yokuxilonga ngamanani owafunayo bese uwaqhathanisa. Noma yini engaphandle kwebanga elishiwo izokhombisa inzwa engalungile. Faka esikhundleni sayo kulandela izinqubo ezifanele zokulungisa kabusha.
