P02A5 Silinda 3 Injector Leak

Bayanan Bayani na OBD-II

Fitowa daga injector na silinda 3

Mene ne wannan yake nufi?

Wannan sigar lambar rikitarwa ce mai rikitarwa (DTC) kuma galibi ana amfani da ita ga motocin OBD-II. Wannan na iya haɗawa amma ba'a iyakance ga ababen hawa daga, da dai sauransu Duk da yanayin gabaɗaya, madaidaicin matakan gyara na iya bambanta dangane da shekarar, ƙirar, ƙirar da tsarin watsawa.

Idan abin hawa na OBD-II ɗinku ya adana lambar P02A5, yana nufin cewa tsarin kula da wutar lantarki (PCM) ya gano yuwuwar injector na man fetur don keɓaɓɓen silinda na injin, a wannan yanayin silinda # 3.

Injectors na mai na mota suna buƙatar matsin lamba na mai don isar da ainihin adadin mai a cikin madaidaicin tsari zuwa ɗakin ƙona kowane silinda. Bukatun wannan madaidaiciyar da'irar na buƙatar kowane injector na mai ya kasance ba tare da ɓarna da ƙuntatawa ba.

Kwamfutar PCM tana lura da dalilai kamar datsa man da ake buƙata da kuma bayanan firikwensin iskar oxygen, tare da matsayin crankshaft da matsayin camshaft, don gano cakuda mai ɗorawa da gano abin da injin silinda ke aiki mara kyau.

Alamu na bayanai daga firikwensin iskar oxygen suna gargadin PCM game da ƙarancin iskar oxygen a cikin iskar gas da kuma abin da injin ɗin ya shafa. Da zarar an ƙaddara cewa akwai murɗaɗɗen murɗaɗɗen murɗawa a kan wani injin injin, matsayin camshaft da crankshaft yana taimakawa sanin wanene injector ke da matsalar. Da zarar PCM ta ƙayyade ɗanyen cakuda ya wanzu kuma ya gano injector mai lalacewa a kan silinda # 3, za a adana lambar P02A5 kuma fitilar mai nuna rashin aiki (MIL) na iya haskakawa.

A wasu ababen hawa, yana iya ɗaukar da'irar rashin nasara da yawa don MIL ya haskaka.

Menene tsananin wannan DTC?

Yakamata a rarrabe P02A5 a matsayin mai ƙarfi saboda cakuda mai mai ɗora zai iya lalata kan silinda ko injin.

Menene wasu alamomin lambar?

Alamomin lambar matsala P02A5 na iya haɗawa da:

  • Rage aikin injiniya
  • Rage ingancin man fetur
  • Lambobi masu lanƙwasa
  • Hakanan za'a iya adana lambobin wuta

Mene ne wasu abubuwan da ke haifar da lambar?

Dalilan wannan lambar injector na P02A5 na iya haɗawa da:

  • Lahani da / ko fitar da injector na mai
  • Buɗewa ko gajere kewaye a cikin sarkar (s) na injector na mai
  • Na'urar haska (s) mara kyau
  • PCM ko kuskuren shirye -shirye
  • Malfunctioning Mass Air Flow (MAF) ko Manifold Air Pressure (MAP) Sensor

Menene matakan warware matsalar P02A5?

Dole ne a bincika lambobin MAF da MAP kafin a yi ƙoƙarin tantance lambar P02A5.

Ina so in fara ganewar asali tare da dubawa gaba ɗaya na yankin dogo na mai. Zan mai da hankali kan injector din mai tambaya (# 3 silinda). Bincika a waje don lalata da / ko leaks. Idan akwai tsatsa mai ƙarfi a waje na injector ɗin da ake magana akai, ko kuma idan ya zube, yi zargin cewa ya gaza.

Idan babu matsalolin injin a bayyane a cikin injin injin, za a buƙaci kayan aiki da yawa don yin cikakkiyar ganewar asali:

  1. Na'urar Bincike
  2. Digital Volt / Ohmmeter (DVOM)
  3. Stethoscope mota
  4. Amintaccen tushen bayanin abin hawa

Sannan na haɗa na'urar daukar hotan takardu zuwa tashar binciken mota kuma na sami duk lambobin da aka adana da daskare bayanan firam. Wannan zai taimaka yayin bincike na ya ci gaba. Yanzu zan share lambobin kuma in gwada abin hawa don ganin an sake saita P02A5.

Idan lambar P02A5 ta dawo nan da nan, yi amfani da na'urar daukar hotan takardu don yin gwajin ma'aunin injector don tabbatar da cewa gobarar matsala ce ta injector. Da zarar kun yi hakan, je zuwa mataki na 1.

Mataki 1

Tare da injin yana aiki, yi amfani da stethoscope don sauraron injector ɗin da ya dace. Yakamata a ji sautin dannawa mai ji, yana maimaitawa cikin tsari. Idan babu sauti, je zuwa mataki na 2. Idan ya cancanta, gwada sauti daga injector na wannan silinda tare da sauran sautuna don kwatantawa.

Mataki 2

Yi amfani da DVOM don bincika ƙarfin lantarki da motsin ƙasa tare da injin yana gudana. Yawancin masana'antun suna amfani da tsarin wutar lantarki na baturi mai ɗorewa a ɗaya daga cikin tashar injector na mai da bugun ƙasa (daga PCM) wanda ake amfani da shi a ɗayan tashar a lokacin da ya dace.

Idan ba a gano wani ƙarfin lantarki ba a cikin mahaɗin injector na man fetur, yi amfani da DVOM don gwada fuses da relays na tsarin. Sauya fuses da / ko relays idan ya cancanta.

Ina son gwada fuses a cikin tsarin da kewaya a ƙarƙashin kaya. Fuse mara lahani wanda ya bayyana yana da kyau lokacin da ba a loda da'irar ba (maɓallin kunnawa / kashe injin) na iya kasawa lokacin da aka ɗora da'irar (maɓallin kunnawa / injin yana aiki).

Idan duk fuses da relays ɗin sun yi daidai kuma babu ƙarfin lantarki, yi amfani da tushen bayanan abin hawan ku don gano da'irar ta koma canjin ƙonewa ko ƙirar allurar mai (idan an zartar).

Lura. Yi amfani da taka tsantsan lokacin dubawa / maye gurbin babban tsarin man fetur.

Kuna buƙatar ƙarin taimako tare da lambar P02A5?

Idan har yanzu kuna buƙatar taimako tare da DTC P02A5, aika tambaya a cikin sharhin da ke ƙasa wannan labarin.

NOTE. An ba da wannan bayanin don dalilai na bayanai kawai. Ba a yi nufin amfani da shi azaman shawarar gyara ba kuma ba mu da alhakin duk wani mataki da za ku ɗauka a kan kowane abin hawa. Duk bayanan da ke wannan shafin ana kiyaye su ta haƙƙin mallaka.
