I-P023E MAP - B Turbo/SC Boost sensor correlation

Idatha ye-OBD-II DTC

I-Manifold Absolute Pressure - Isilinganiso Senzwa ye-Turbocharger/Supercharger B

Kusho ukuthini lokhu?

Le yikhodi enenkinga yokuxilonga i-powertrain (DTC) ejwayelekile futhi isetshenziswa kakhulu ezimotweni ze-OBD-II. Lokhu kungafaka, kepha kungagcini lapho, izimoto ezisuka kwaLand Rover (Range Rover, Discovery), Ford, Chevrolet, Mazda, Dodge, Peugeot, Saab, Toyota, njll.

Yize kuvamile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngemodeli yonyaka, ukwakheka, imodeli, nokucushwa kokudluliswa.

Uma imoto yakho efakwe i-OBD-II igcine ikhodi engu-P023E, kusho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole ukungafani kumasiginali ahambisanayo phakathi kwenzwa eningi kakhulu yengcindezi (MAP) kanye ne-turbocharger / supercharger boost sensor, ebiyi kuphawulwe "B" ...

Uhlamvu oluthi “B” lukhomba inzwa ethile yokuqinisa ohlelweni olungasebenzisa izinzwa zokuqinisa eziningi ezindaweni ezahlukene. Xhumana nomthombo wolwazi wemoto onokwethenjelwa ukuthola ukuthi iyiphi inzwa B ekhuluma ngayo (ngemoto okukhulunywa ngayo). Le khodi isebenza kuphela ezimotweni ezinemishini yokuphakela umoya enhle. Izinsiza zomoya eziphoqelelwe zifaka ama-turbocharger nama-blower.

Inzwa ye-MAP inikezela i-PCM ngesiginali yamandlavezi ekhombisa ukuminyana noma ingcindezi yomoya ophindaphindiwe wokungenisa. Isiginali ye-voltage yamukelwa (PCM) ngamayunithi ama-kilopascals (kPa) noma ama-intshi we-mercury (Hg). Kwezinye izimoto, ingcindezi ye-barometric ithathelwa indawo ingcindezi ye-barometric, elinganiswa ngokunyuka okufanayo.

Inzwa yokuqinisa ingcindezi ye-turbocharger / supercharger (enelebuli B) kungenzeka ibe ngeyokwakheka okufanayo kunzwa ye-MAP. Iqapha ukuminyana komoya (umfutho wokunyusa umfutho) ngaphakathi kwepayipi lokungenisa le-turbocharger / supercharger futhi inikeze i-PCM isiginali yamandla kagesi ehambisanayo.

Kuzogcinwa ikhodi engu-P023E futhi ilambu lenkomba yokungasebenzi (MIL) lingakhanyisa uma i-PCM ithola izimpawu zamandla kagesi phakathi kwenzwa ye-MAP ne-turbocharger / supercharger sensor B eyehluke kakhulu kuneziqu ezihleliwe. I-MIL ingadinga imijikelezo eminingi yokushisa (ngokuhluleka) ukukhanyisa.

Buyini ubunzima bale DTC?

Ukusebenza kwezinjini jikelele nomnotho kaphethiloli kungathinteka kabi ngenxa yezimo ezifaka ikhodi ye-P023E. Kufanele ihlukaniswe njengosindayo.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P023E zingafaka:

Inciphise amandla enjini
Ukukhipha okucebile ngokweqile noma okuncanyana
Ukubambezeleka kokuqala injini (ikakhulukazi kubanda)
Ukunciphisa ukusebenza kwephethiloli

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izimbangela zale P023E DTC zingafaka:

I-MAP enephutha / iTurbocharger / Inzwa yokukhuthaza iB
Isifunda esivulekile noma esifushane ku-wiring noma kusixhumi se-MAP sensor / turbocharger / supercharger B
Ukuhluleka kwenjini (ukukhiqizwa kokungenela okunganele)
I-intercooler enomkhawulo
Iphutha lokuhlela le-PCM noma le-PCM

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P023E?

Ngaphambi kokuzama ukuthola ikhodi ye-P023E, ngingaqala ngithole isithwebuli sokuxilonga, i-digital volt / ohmmeter (i-DVOM), igeji yokuphathwa ngesandla, nomthombo othembekile wolwazi lwemoto. Ukuthola noma iyiphi ikhodi ehlotshaniswa ne-MAP sensor kufanele kufaka phakathi ukuqinisekisa ukuthi injini yakha i-vacuum eyanele. Lokhu kungenziwa kusetshenziswa igeji yokuhlanza.

Ukuhlolwa okubonakalayo kwayo yonke i-MAP / turbocharger / supercharger sensor wiring nezixhumi kulungile uma nje kungekho ziphazamiso ku-intercooler futhi isihlungi somoya sihlanzekile. Lungisa uma kunesidingo. Ngibe sengixhuma isithwebuli ethekwini lokuxilonga imoto ngathola wonke amakhodi agciniwe futhi ngafriza idatha yozimele. Friza idatha yohlaka ingachazwa kangcono njengesifinyezo sezimo eziqondile ezenzeke ngesikhathi sephutha eliholele kukhodi egciniwe ye-P023E. Ngithanda ukubhala lolu lwazi phansi ngoba lungasiza ekuhloleni izifo. Manje sula amakhodi bese uhlola ukushayela imoto ukuqinisekisa ukuthi ikhodi isuliwe.

Uma lokhu:

Hlola ama-MAP / turbocharger / supercharger wokunyusa ama-sensors asebenzisa i-DVOM kanye nomthombo wolwazi wemoto yakho.
Beka i-DVOM kusethingi ye-Ohm bese uhlola izinzwa ngenkathi zingakhishiwe.
Xhumana nomthombo wolwazi lwemoto yakho ngemininingwane yokuhlolwa kwengxenye.
Izinzwa ze-MAP / turbocharger / zokuqinisa ezingahlangabezani nezincazelo zomkhiqizi kufanele zishintshwe.

Uma zonke izinzwa zihlangabezana nezincazelo zomkhiqizi:

Hlola i-voltage reference (ngokuvamile engu-5V) kanye nomhlabathi kuzixhumi zenzwa.
Sebenzisa i-DVOM bese uxhuma ukuhola kokuhlolwa okuqondile kuphini lereferensi yamandla esixhumi senzwa, nokuhlolwa okungekuhle kuholele kuphini lomhlabathi wesixhumi.

Uma uthola i-voltage voltage nomhlabathi:

Xhuma inzwa bese uhlola isekhethi yesiginali yenzwa isebenza ngenjini.
Landela umdwebo wokushisa nowamandla atholakala emthonjeni wolwazi lwemoto ukuthola ukuthi izinzwa ezihambisanayo zisebenza kahle yini.
Izinzwa ezingakhombisi izinga le-voltage elicacisiwe lomkhiqizi (ngokusho kwengcindezi eningi ephindaphindwe kanye nengcindezi yokuqinisa amandla we-turbocharger / supercharger) kufanele ithathelwe indawo.

Uma isekhethi yesiginali yenzwa ikhombisa ileveli efanele yamandla kagesi:

Hlola isekethe yesiginali (ngenzwa okukhulunywa ngayo) kusixhumi se-PCM. Uma kunesiginali yenzwa kusixhumi senzwa kodwa hhayi kusixhumi se-PCM, kunesekethe evulekile phakathi kwalezi zingxenye ezimbili.
Hlola amasekethe wesistimu ngamanye nge-DVOM. Nqamula i-PCM (kanye nazo zonke izilawuli ezihambisanayo) bese ulandela ishadi lokugeleza lokuhlola noma amaphini wokuxhuma ukuhlola ukumelana kanye / noma ukuqhubeka kwesekethe ngayinye.

Uma wonke ama-MAP / turbocharger / supercharger eqinisa izinzwa zokucindezela namasekethe angaphakathi kokucacisiwe, sola ukwehluleka kwe-PCM noma iphutha lohlelo lwe-PCM.

Buyekeza ama-Technical Service Bulletins (TSB) ukuze uthole usizo ngokuxilongwa.
Inzwa yokuqinisa i-turbocharger / supercharger ivame ukuhlala ikhubazekile ngemuva kokushintsha kwesihlungi somoya nokunye ukugcinwa okuhlobene.

Izingxoxo ezihlobene ze-DTC

Okwamanje azikho izihloko ezihlobene ezinkundleni zethu. Thumela isihloko esisha esithangamini manje.

Udinga usizo olwengeziwe ngekhodi le-P023E?

Uma usadinga usizo nge-DTC P023E, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
