Rashin aiki na firikwensin matattarar iskar gas "B"

Mene ne wannan yake nufi?

Wannan Generic Powertrain / Engine DTC ya shafi duk injunan da ke amfani da turbochargers mai canzawa (gas ko dizal) tun kusan 2005 akan manyan motocin Ford da ke sanye da injin diesel 6.0L, duk injunan Ford EcoBoost, kuma a ƙarshe ƙarshe ke kaiwa ga samfurin Cummins 6.7 L. 2007, 3.0L a cikin jeri na Mercedes a 2007 kuma kwanan nan a nan Cummins 3.0L 6-cylinder a cikin motocin Nissan da aka fara a 2015. Wannan ba yana nufin ba lallai ne ku sami wannan lambar akan VW ko wata ƙirar ba.

Wannan lambar tana nuna cewa siginar shigarwa daga firikwensin matattarar iskar gas ba ta dace da matsin lamba mai yawa ko matsin lamba na yanayi lokacin da aka kunna maɓalli. Zai iya zama lahani na lantarki ko na inji.

P047B kuma yana iya kasancewa a lokaci guda da P047A. Bambanci kawai tsakanin lambobin biyu shine tsawon lokacin da matsalar ta kasance da kuma irin matsalar lantarki / injin da mai sarrafa firikwensin / kewaye / injin ke fuskanta. Matakan matsala na iya bambanta dangane da mai ƙera, man fetur ko dizal, nau'in firikwensin matsin lamba da launin waya. Tuntuɓi takamaiman littafin gyaran abin hawa don sanin wane firikwensin “B” takamaiman abin hawa yake da shi.

da bayyanar cututtuka

Alamomin lambar injin P047A na iya haɗawa da:

  • Duba hasken Injin yana kunne
  • Rashin iko
  • Ba za a iya aiwatar da sabuntawar hannu ba - ƙona matattarar barbashi daga cikin tacewa. Yana kama da mai canzawa, amma yana da firikwensin zafin jiki da na'urori masu auna matsa lamba a ciki.
  • Idan sake farfadowa ya kasa, farkon farawa ba zai iya faruwa a ƙarshe ba.

Dalili mai yiwuwa

Yawanci dalilin shigar da wannan lambar shine:

  • Clogged tube daga shaye -shaye mai yawa zuwa firikwensin matsa lamba
  • Maimaita Iskar Gas / Shigar da Jirgin Sama / Cajin Jirgin Sama
  • Na'urar haska iskar gas
  • Module Control Module (PCM) na iya kasa (da wuya)

Hanyoyin bincike da gyara

Kyakkyawan farawa shine koyaushe samun Bulletin Sabis na Fasaha (TSB) don takamaiman abin hawa. Mai ƙera abin hawa yana iya samun ƙwaƙwalwar ƙwaƙwalwar filasha / sake fasalin PCM don gyara wannan matsalar kuma yana da kyau a bincika kafin ku sami kanku kuna tafiya mai nisa / kuskure.

Sannan sami firikwensin matsin lamba akan takamaiman abin hawa. Da zarar an gano, cire haɗin bututun da ke haɗa firikwensin zuwa ninki da yawa. Yi ƙoƙarin karya ta wannan. Idan wannan ba zai yiwu ba, gwada ƙoƙarin kunna ƙaramin waya ta ciki don cire carbon da ke makale a ciki wanda ke haifar da DTC da kuke fuskanta. Idan bututun yana da tsabta kuma a kwance, a duba masu haɗawa da wayoyi. Nemo ɓarna, ɓarna, wayoyi da aka fallasa, alamomin ƙonawa, ko narkakken filastik. Cire haɗin haɗin kuma a hankali bincika tashoshi (sassan ƙarfe) a cikin masu haɗin. Duba idan sun yi kama da tsatsa, ƙonewa, ko yuwuwar kore idan aka kwatanta da launin ƙarfe da aka saba gani da alama ana iya gani. Idan ana buƙatar tsaftacewa ta ƙarshe, zaku iya siyan mai tsabtace lambar wutar lantarki a kowane shagon sassa. Idan wannan ba zai yiwu ba, sami 91% shafa barasa da goga mai goga mai filastik don tsabtace su. Sannan bari su bushe da iska, ɗauki sinadarin silicone na dielectric (irin kayan da suke amfani da su don masu riƙe da kwan fitila da wayoyi masu walƙiya) kuma sanya wurin da tashoshin ke tuntuɓar. Sannan a duba cewa bututun da ke haɗa turbocharger zuwa ninki mai yawa ba ya zubowa. Duba duk hanyoyin haɗin bututu da ke kusa da turbocharger da yawa. Allauke duk abin da aka ɗora.

Idan kuna da kayan aikin sikirin, share lambobin matsalar bincike daga ƙwaƙwalwar ajiya kuma duba idan lambar ta dawo. Idan wannan ba haka bane, to akwai yuwuwar matsalar haɗin gwiwa.

Idan lambar ta dawo, za mu buƙaci gwada firikwensin da hanyoyin da ke da alaƙa. Yawancin lokaci akwai wayoyi 3 akan firikwensin matsa lamba.

Cire haɗin kayan doki daga firikwensin matsa lamba. Yi amfani da ohmmeter na dijital na dijital (DVOM) don bincika kewayon wutar lantarki na 5V yana zuwa firikwensin don tabbatar da cewa yana kan (ja waya zuwa da'irar samar da wutar lantarki na 5V, baƙar fata zuwa ƙasa mai kyau). Idan firikwensin shine 12 volts lokacin da yakamata ya zama 5 volts, gyara wayoyi daga PCM zuwa firikwensin don gajere zuwa 12 volts ko wataƙila PCM mara kyau.

Idan wannan al'ada ce, tare da DVOM, tabbatar cewa kuna da 5V akan keɓaɓɓen siginar siginar matsa lamba (jan waya zuwa keɓaɓɓen siginar siginar, waya baƙi zuwa ƙasa mai kyau). Idan babu 5 volts akan firikwensin, ko kuma idan kun ga 12 volts akan firikwensin, gyara wayoyi daga PCM zuwa firikwensin, ko kuma, wataƙila PCM mara kyau.

Idan na al'ada ne, bincika cewa firikwensin matsin lamba ya yi ƙasa sosai. Haɗa fitilar gwaji zuwa tabbataccen batirin 12 V (ja m) kuma taɓa ɗayan ƙarshen fitilar gwajin zuwa da'irar ƙasa wanda ke kaiwa zuwa filin haska matattarar iskar gas. Idan fitilar gwajin ba ta haskaka ba, yana nuna alamar da'irar mara kyau. Idan ya haskaka, girgiza kayan haɗin waya zuwa kowane firikwensin don ganin idan fitilar gwajin ta yi ƙyalƙyali, yana nuna haɗin haɗin kai.

Idan duk gwaje -gwaje sun wuce zuwa yanzu kuma kuna ci gaba da samun lambar P047A, da alama zai iya nuna firikwensin matsin lamba, kodayake PCM da ya gaza ba za a iya yanke hukunci ba har sai an maye gurbin firikwensin.

Tattaunawar DTC mai dangantaka

  • A halin yanzu babu batutuwa masu alaƙa a cikin dandalin mu. Sanya sabon taken akan dandalin yanzu.

Kuna buƙatar ƙarin taimako tare da lambar p047a?

Idan har yanzu kuna buƙatar taimako game da DTC P047A, 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.
