P02A8 Isilinda 4 injector limited

P02A8 Isilinda 4 injector limited

Idatha ye-OBD-II DTC

Ukuvimbela injector isilinda 4

Kusho ukuthini lokhu?

Le yikhodi enenkinga yokuxilonga i-powertrain (DTC) ejwayelekile futhi isetshenziswa kakhulu ezimotweni ze-OBD-II. Lokhu kungafaka, kepha kungagcini lapho, izimoto zakwaFord (iTransit, Focus, njll.), ILand Rover, iMitsubishi, iMaybach, iDodge, iSubaru, njll. Naphezu kwemvelo ejwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngonyaka wokwenziwa , brand, imodeli nokudluliswa. ukumiswa.

Uma imoto yakho ene-OBD-II igcine ikhodi ye-P02A8, kusho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole umkhawulo ongaba khona kumjovo wephethiloli wesilinda esithile enjinini, kulokhu isilinda # 4.

Amajektha ophethiloli wezimoto adinga ukucindezelwa ngophethiloli okuqondile ukuze ahambise inani eliqondile likaphethiloli ngephethini eline-athomu ngqo ekamelweni lomlilo lesilinda ngasinye. Izidingo zalesi sifunda esiqondile zidinga umjovo ngamunye kaphethiloli ukuthi ungabi nokuvuza nemikhawulo.

Ama-PCM aqaphe izinto ezinjenge-fuel trim edingekayo kanye ne-exhaust data sensor, ngokuhlangana ne-crankshaft position kanye ne-camshaft position, ukuthola ingxube enciphileyo bese ukhomba ukuthi iyiphi i-cylinder engasebenzi kahle.

Amasiginali wedatha avela ezinzwa zomoya-mpilo axwayisa i-PCM ngokuqukethwe komoya-mpilo okuncane kumagesi e-exhaust nokuthi iyiphi injini ethintekayo ethintekayo. Uma sekunqunyiwe ukuthi kukhona ingxube yokukhipha enciphile ebhlokini ethile yenjini, ukuma kwe-camshaft ne-crankshaft kusiza ukunquma ukuthi iyiphi i-injector enenkinga. Lapho i-PCM isinqume ukuthi kukhona ingxube enciphile futhi ithola umjovo wephethiloli owonakele kusilinda # 4, kuzogcinwa ikhodi engu-P02A8 bese kuthi isibani sesikhombisi esingasebenzi kahle (MIL) sikhanye.

Ezinye izimoto zingadinga imijikelezo eminingi yokwehluleka ukuze i-MIL ikhanyise.

Isiphambano somjovo ojwayelekile wephethiloli:

Buyini ubunzima bale DTC?

I-P02A8 kufanele ihlukaniswe ngamandla njengoba inhlanganisela yamafutha ekhuluphele ingalimaza ikhanda lesilinda noma injini.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P02A8 zingafaka:

• Ukunciphisa ukusebenza kwenjini
• Ukunciphisa ukusebenza kwephethiloli
• Amakhodi wokukhipha anciphile
• Amakhodi wokugculisa nawo angagcinwa

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi yokujova i-P02A8 ingafaka:

• Isijova sikaphethiloli esinamaphutha kanye / noma esiminyene
• Isifunda esivulekile noma esifushane kumaketanga we-injector fuel
• Inzwa (oksijini) enamaphutha
• I-PCM noma iphutha lohlelo
• Ukungasebenzi kahle kwenzwa yokugeleza komoya (MAF) noma inzwa yomfutho womoya omningi (MAP)

Yiziphi izinyathelo ze-P02A8 zokuxazulula inkinga?

Amakhodi ahlobene ne-MAF ne-MAP kufanele atholakale futhi alungiswe ngaphambi kokuzama ukuthola ikhodi ye-P02A8.

Ngithanda ukuqala ukuxilongwa kwami ​​ngokuhlolwa okujwayelekile kwendawo yesitimela sikaphethiloli. Ngingagxila kumjovo wephethiloli okukhulunywa ngawo (isilinda # 4). Ngaphandle hlola ukugqwala kanye / noma ukuvuza. Uma kukhona ukugqwala okukhulu ngaphandle kwe-injector ye-fuel okukhulunywa ngayo, noma uma kuvuza, sola ukuthi ihlulekile.

Uma kungekho zinkinga ezisobala zomshini egumbini lenjini, amathuluzi amaningi azodingeka ukwenza ukuxilongwa okunembile:

1. Isithwebuli sokuhlola
2. I-Digital Volt / Ohmmeter (i-DVOM)
3. I-stethoscope yemoto
4. Umthombo onokwethenjelwa wolwazi lwemoto

Ngibe sengixhuma isithwebuli ethekwini lokuxilonga imoto ngathola wonke amakhodi agciniwe futhi ngafriza idatha yozimele. Lokhu kuzoba wusizo njengoba ukuxilongwa kwami ​​kuqhubeka. Manje sengizosula amakhodi bese ngivivinya ukushayela imoto ukubona ukuthi i-P02A8 isethwe kabusha.

Uma ikhodi ye-P02A8 ibuya ngokushesha, sebenzisa isithwebuli ukwenza isivivinyo se-injector balance ukuqinisekisa ukuthi i-misfire iyinkinga yomjovo. Lapho usukwenzile lokho, iya kusinyathelo 1.

Isinyathelo 1

Lapho injini isebenza, sebenzisa i-stethoscope ukulalela i-injector efanelekile ye-fuel. Umsindo wokuqhafaza ozwakalayo kufanele uzwakale, uphinda ngephethini. Uma kungekho msindo, yiya esinyathelweni sesi-2. Uma kungumcibisholo noma kuphakathi nendawo, sola ukuthi umjovo ongu-4 unephutha noma uvalekile. Uma kunesidingo, qhathanisa imisindo evela ku-injector yalesi silinda neminye imisindo yokuqhathanisa.

Isinyathelo 2

Sebenzisa i-DVOM ukuhlola amandla we-voltage nomhlabathi ngenjini esebenza. Abakhiqizi abaningi basebenzisa i-voltage system yebhethri engaguquki endaweni eyodwa ye-injector ye-fuel kanye ne-pulse yomhlabathi (kusuka ku-PCM) esetshenziswe kwesinye isiginali ngesikhathi esifanele.

Uma kungatholakali i-voltage kusixhumi esihambisayo se-fuel injector, sebenzisa i-DVOM ukuhlola amafyuzi ohlelo nokudluliswa. Shintsha amafyuzi kanye / noma udlulisele uma kunesidingo.

Ngithanda ukuvivinya amafyuzi ohlelweni olunomjikelezo ongaphansi komthwalo. I-fuse enamaphutha ebonakala ilungile lapho isekethe lingalayishiwe (ukhiye uvuliwe / u-injini uvaliwe) ungahluleka lapho isifunda silayishwa (ukhiye uvuliwe / usebenza ngenjini).

Uma wonke ama-fuses esistimu nokudluliswa kulungile futhi kungekho voltage ekhona, sebenzisa umthombo wemininingwane yakho yemoto ukulandelela isekethe kushintshi lokushisa noma kumjovo we-fuel module (uma ikhona).

Qaphela. Sebenzisa ukuqaphela lapho uhlola / ushintsha izingxenye zezinto ezisebenzisa umfutho ophakeme.
