Matsalar iskar gas mai sarrafa bawul "B"

Mene ne wannan yake nufi?

Wannan Deric Genication Transmission / Engine DTC galibi ya shafi injunan diesel da suka haɗa da, amma ba'a iyakance su ba, wasu motocin Ford, Dodge, Mercedes, Nissan, da VW.

Hakanan za'a iya amfani da wannan lambar ga manyan motocin da ke sanye da injunan dizal da birki na sharar dillali.

Ana sanya bawul ɗin a cikin rafi mai ɗorewa ƙarƙashin ƙasa na iskar gas mai yawa don samar da zafi a cikin yanayin matsin baya a cikin fitarwa. Ana iya amfani da wannan zafin da / ko matsin lamba don dumama yayin fara sanyi. Hakanan ana iya amfani da shi don magance matsin lamba a cikin silinda da ke fitowa daga injin silinda injin daga iskar gas, ta yadda zai rage injin da abin hawa tare da shi. Wannan yana da amfani musamman lokacin towing.

Wannan lambar tana da tsananin ƙarfi don sarrafa fitowar matsin lamba mai sarrafa wutar lantarki. Ana ɗaukar wannan lambar a matsayin kuskure a cikin da'irar lantarki kawai.

Matakan warware matsala na iya bambanta dangane da mai ƙera, nau'in mai sarrafa matsin lamba na baya da launuka na wayoyi zuwa solenoid mai sarrafawa. Tuntuɓi takamaiman littafin gyaran abin hawa don sanin wane bawul "B" yake don aikace -aikacen ku na musamman.

da bayyanar cututtuka

Alamomin lambar injin P049F na iya haɗawa da:

• Lambar Alamar Rashin Aiki (MIL) ta haskaka
• Rashin iko
• Babu injin birki
• Tsawon lokaci fiye da yadda aka saba don injin sanyi

Dalili mai yiwuwa P049F

Yawanci dalilin shigar da wannan lambar shine:

• Gajeriyar hanyar zuwa + baturi a cikin da'irar wutar lantarki tsakanin keɓaɓɓen kula da matsin lamba da PCM (tsarin sarrafa watsawa)
• Buɗe a cikin da'irar wutar lantarki tsakanin keɓaɓɓen kula da matsin lamba da PCM
• Short circuit on ground in the power supply circuit of the solenoid of pressure pressure of gas gas
• Ikon sarrafa bututun iskar gas mara ƙarfi
• PCM na iya faduwa (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 nemo bawul ɗin sarrafa siginar “B” na iskar gas akan takamaiman abin hawa. Da zarar an gano, duba abubuwan gani 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 tsatsa, ƙonewa, ko wataƙila 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 goge goge 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) da kuma sanya inda tashoshin ke tuntuɓar.

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 solenoid da da'irori masu alaƙa. Yawanci, wayoyi 2 suna haɗawa da iskar gas mai sarrafa iskar gas. Cire haɗin kayan doki daga sarrafawar matsin lamba na farko. Yin amfani da volt volt ohmmeter (DVOM), haɗa gubar mita ɗaya zuwa tashar tashar soloid ɗaya. Haɗa ragowar gubar mita zuwa sauran tashar tafin tafin kafa. Ba dole ba ne a buɗe ko gajere. Duba halayen juriya don takamaiman abin hawa. Idan solenoid yana buɗe ko gajarta (juriya mara iyaka ko babu juriya / 0 ohms), maye gurbin solenoid.

Idan wannan na al'ada ne, tare da DVOM, tabbatar cewa kuna da ikon 12V zuwa madaidaicin ikon sarrafa matsin lamba (jan waya zuwa madaidaicin wutar lantarki, waya ta baki zuwa ƙasa mai kyau). Tabbatar an kunna wuta. Idan solenoid ba 12 volts ba, ko kuma idan akwai 12 volts tare da kashewa, gyara wayoyi daga PCM ko aikawa zuwa tafin kafa, ko wataƙila PCM mara kyau.

Idan na al'ada ne, duba cewa sarrafawar bawul ɗin sarrafa madaidaicin bawul ɗin 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 ga sarrafa wutar iskar gas mai ƙarfi. 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 P049F, wataƙila zai nuna ƙarancin ikon sarrafa matsin lamba, kodayake PCM da ya gaza ba za a iya yanke hukunci ba har sai an maye gurbin tafin.

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

Kuna buƙatar ƙarin taimako tare da lambar p049F?

Idan har yanzu kuna buƙatar taimako tare da lambar kuskuren P049F, 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.
