Barometric Pressure Inofambisa B: Range / Performance

Izvi zvinorevei?

Iyi generic powertrain diagnostic dambudziko kodhi (DTC) uye inowanzo shandiswa kune OBD-II mota. Mota dzakakanganiswa dzinogona kusanganisira, asi hadziganhurwe, Chevy, Mazda, Volvo, Acura, Honda, BMW, Isuzu, Mercedes Benz, Cadillac, Hyundai, Saab, Ford, GMC, nezvimwe zvichienderana negore. , gadzira, modhi uye zvishandiso zveyuniti yemagetsi.

Mazhinji enjini ekudzora zvikamu (ECMs) zvinovimba nenhamba dzakasiyana dzezviyero kuti zvinyatso kupa iyo injini ine yakakwana mweya-peturu reshiyo. Iyo "yakakwana" mweya / mafuta chiyero chinonzi "stoichiometric" musanganiswa: 14.7 zvikamu zvemhepo kune chimwe chikamu mafuta. Humwe hunhu hunodzorwa neECM kuchengetedza musanganiswa wemafuta se stoichiometric sezvinobvira, asi haigumiri kune: kuyerera kwemhepo, kutonhora kwekutonhora, kumhanya kweinjini, kudiwa kwemutoro, tembiricha yemuchadenga, nezvimwe. pane yekudyira uye ambient mweya. kumanikidza kugadzirisa musanganiswa.

Tisingataure, masisitimu aya anoshandisa mashoma masensa kuti awane mibairo yakafanana kusvika pakubata kwemafuta / kushanda zvakanaka kunoenda zvakadaro. Kazhinji BAP (barometric air pressure) masensa anoshandiswa kana MAP (manifold absolute pressure) masensa aripowo. MaBAP anoshandiswa kuyera kumanikidzwa kwemhepo. Ukoshi uhwu hwakakosha pakuona kusanganiswa kwemafuta, sezvo ECM inoda kuenzanisa kudzvanywa kwemuchadenga nekumanikidza kwekudyara kwakawanda kuitira kunyatsogadzirisa musanganiswa wemafuta kune zvinodiwa nemutyairi. Hurefu chinhu chakakosha kutariswa kana uchiongorora BAP. Zvichienderana nenzvimbo yako, zviratidzo zvako zvinogona kuwedzera zvakanyanya kana kuvandudza, kunyanya kana uchifamba kazhinji munzvimbo dzine makomo.

Tsamba painosanganisirwa murondedzero yeOBD2 DTC (mune iyi nyaya "B"), mune dzakawanda zviitiko zvinoratidza chimwe chinhu chakanangana (semuenzaniso, akasiyana mabhangi, ma sensors, maseketi, ma connector, nezvimwewo) muhurongwa umo Iwe uripo. kushanda mukati. Mune ino kesi, ini ndaiti ndione kuti ndeipi sensor yauri kushanda nayo. Pachawanzo kuve nemaabarometric sensors ekupa kuverenga chaiko. Uye zvakare, kuwirirana pakati pemaseru ekubatsira mukubata mafuta, tisingatauri kuti zvinobatsira kuwana zvikanganiso mumaseru kana kumatunhu. Nezve zvese zviri pamusoro, tarisa kubhuku rako rebasa kune mamwe mavara etsamba yemota yako.

P222B inoiswa neECM kana ichinge yaona kuti bharometric pressure (BAP) sensor "B" kana maseketi ayo ari kushanda asi kwete mukati memagetsi, kana ari kushanda zvisina kujairika kana zvisina basa.

Barometric kumanikidza Switch:

Chii chakakomba cheiyi DTC?

Kuomarara apa kuchave kwakakwirira zvine mwero. Ndichiri kuverenga izvi, panofanirwa kuve nekumwe kukurumidzira kuti injini igone kushanda nemazvo. Chero nguva iyo kutadza kushanda paunogona kukanganisa zvakananga kukosha kwakanyanya senge mweya / mafuta chiyero uye ichinyatsovapo, haufanire kutyaira mota yako kudzivirira kukuvara kweinjini. Izvo zviri kutaurwa, kana iwe ukatyaira mota mushure mekukanganisa kwaive kuchishanda, usazvidya moyo zvakanyanya, unogona kunge wakanaka. Iyo hombe yekutora ndeyekuti kana ikasiiwa isina kutarisirwa, inogona kutungamira kune anodhura emukati injini kukuvara mune ramangwana.

Ndezvipi zvimwe zvezviratidzo zvekodhi?

Zviratidzo zveP222B kodhi yekunetseka inogona kusanganisira:

• Isina kukwana injini simba uye kuita (kana kushomeka)
• Injini yakashata
• Isina kujairika injini ruzha
• Mafuta anonhuwirira
• Kuderedzwa kwehupfumi hwemafuta
• Yakaderedzwa kugwinha kwekunzwa

Ndezvipi zvimwe zvezvikonzero zvinowanzoitika zveiyo kodhi?

Zvikonzero zveiyi P222B kodhi zvinogona kusanganisira:

• Inokanganisa kana kukuvara BAP (mhepo yekumanikidza) sensor
• Yakaremara kana yakakuvara yemagetsi yekubatanidza
• Dambudziko rewiring (semuenzaniso yakavhurika redunhu, pfupi dunhu, ngura)
• Pfupi redunhu (zvemukati kana zvemagetsi)
• Kusimba kwemagetsi kubatana
• Thermal kukuvara
• Mechanical kutadza kukonzera BAP kuverenga kuti ichinje
• ECM (Injini Kudzora Module) dambudziko

Ndeapi mamwe matanho ekutambudza iyo P222B?

Nhanho yekutanga # 1

Tsvaga iyo BAP (Barometric Air Pressure) sensor pane yako chaiyo mota. Mune ruzivo rwangu, nzvimbo dzenzwi idzi dzinosiyana zvakanyanya, saka kusarudza iyo chaiyo sensor kunofanirwa kuve kwakanyanya kukosha. Paunenge uchinge wawanikwa, tarisa iyo BAP sensor kune chero kukuvara kwemuviri. Zvinogona kuitika zvinogona kusiyana nenzvimbo, saka funga nezve nharaunda nharaunda (semuenzaniso, tembiricha yakakwira nzvimbo, injini kudedera, zvinhu / marara emugwagwa, nezvimwewo.

Pane chero chinhu chinovhiringidza iyo sensor? Izvi zvinogona kuve chikonzero chekunyepa barometric kudzvanywa kuverenga. Kuverengerwa kwakaringana kwakabatana kune yakakwana injini mashandiro mune aya maficha manejimendi masisitimu.

Nhanho yekutanga # 4

Uchishandisa multimeter uye wakashongedzwa nemagetsi anodikanwa eiyo barometric yemhepo yekumanikidza sensor. Iwe unozofanirwa kukatanura chinobatanidza kubva kune iyo sensor pachayo kuitira kuti uwane iwo mapini. Paunenge iwe waona pini, tevera mirairo yemugadziri yekuongorora neyakakosha tsika uye wozvienzanisa. Chero chinhu chiri kunze kwenzvimbo yakatarwa chinoratidza chakaipa chinonzwa.
