P0444 - OBD-II Bayanin Fasaha na Lambar Matsala

Tsarin Kula da Haɓakawa Mai Haɓakawa Buɗewa

Menene ma'anar lambar kuskure P0444?

Wannan lambar Matsala ta Gano (DTC) babbar lambar watsawa ta OBD-II ce wacce ta shafi duk kera da samfuran motoci daga 1996 zuwa gaba. Koyaya, takamaiman matakan gyara na iya bambanta dangane da ƙirar abin hawan ku.

Lambar P0441 tana da alaƙa da tsarin sarrafa fitar da iska (EVAP). A cikin wannan tsarin, injin yana tsotse tururin mai da yawa daga tankin iskar gas, yana hana shi fitowa cikin yanayi. Ana samun wannan ta hanyar amfani da layin injin da zai kai ga shan injuna, kuma bawul ɗin cirewa ko solenoid yana sarrafa adadin tururin mai da ke shiga injin. Ana sarrafa wannan tsarin ta hanyar tsarin sarrafa wutar lantarki (PCM) ko injin sarrafa injin (ECM).

An kunna lambar P0441 lokacin da PCM/ECM ta gano babu canjin ƙarfin lantarki a bawul ɗin sarrafawa lokacin da aka kunna ta. Wannan lambar tayi kama da lambobin P0443 da P0445.

Don haka, yana nuna yuwuwar matsaloli tare da tsarin EVAP wanda zai iya buƙatar ganewar asali da gyara don tabbatar da abin hawa yana aiki da kyau kuma ya dace da ƙa'idodin muhalli.

Dalili mai yiwuwa

Dalilan DTC P0441 na iya haɗawa da:

1. Kayan aikin waya sako-sako ne ko kuma an cire shi.
2. Bude da'ira a cikin kayan aikin wayar hannu.
3. Bude da'irar solenoid mai sarrafa tsarkakewa.
4. PCM/ECM rashin aiki.
5. Kuskuren EVAP mai sarrafa solenoid bawul.
6. Ana buɗe kayan doki mai sarrafa Evaporative Purge (EVAP) ko gajere.
7. Gas solenoid bawul kula da bawul lantarki kewaye.

Waɗannan dalilai na iya haifar da lambar P0441 kuma dole ne a bincikar su kuma a gyara su don aikin abin hawa na yau da kullun.

Menene alamun lambar kuskure? P0444?

Yadda ake gano lambar kuskure P0444?

Don bincikar DTC P0444, bi waɗannan matakan:

1. Duba kayan aikin waya: Bincika duk masu haɗawa kuma tabbatar an haɗa su daidai. Nemo sako-sako da wayoyi masu lalacewa. Yawanci, baturi ne ke ba da bawul ɗin sarrafa shara kuma ana kunna shi da kashewa bisa ga zagayowar aiki ta PCM/ECM. Yin amfani da zane-zanen wayoyi na masana'anta, ƙayyade nau'in kewayawa kuma bincika ƙarfin baturi lokacin da maɓallin ke kunne. Idan babu wutar lantarki, bibiyar wayoyi kuma gano dalilin asarar wutar lantarki. Bincika amincin kayan aikin wayoyi.
2. Duba solenoid mai tsaftacewa: Bayan cire filogin kayan doki, duba mai haɗin solenoid mai tsaftacewa don ci gaba ta amfani da DVOM. Tabbatar juriya yayi daidai da ƙayyadaddun masana'anta. Idan babu ci gaba, maye gurbin solenoid.
3. Duba PCM/ECM: Yi amfani da kayan aikin bincike na ci gaba mai iya gwada hanya don kunna tsarin EVAP. Tabbatar cewa PCM/ECM yana ba da umarnin tsarin EVAP don kunnawa. Idan tsarin yana aiki daidai, duba mahaɗin kayan aikin PCM/ECM. Dole ne zagaye na aiki ya dace da umarnin PCM/ECM yayin aikin EVAP. Idan babu sake zagayowar aiki, PCM/ECM na iya yin kuskure.

Kurakurai na bincike

Kurakurai lokacin bincikar P0444:

1. Tsallake Gwajin Solenoid Sarrafa: Wasu lokuta masu fasaha na iya rasa wani muhimmin mataki na gwada solenoid mai sarrafa tsarkakewa, suna ɗaukan matsalar tana wani wuri dabam. Duba solenoid da na'urar lantarki ya kamata ya zama ɗaya daga cikin matakai na farko, tun da solenoid yana taka muhimmiyar rawa wajen tafiyar da tsarin EVAP.
2. Binciken PCM/ECM mara kyau: Saboda lambar P0444 tana da alaƙa da aikin PCM/ECM, yin kuskure ko rashin isasshen gwajin aikin sarrafa injin lantarki na iya haifar da sauye-sauye masu tsada lokacin da matsalar ita ce wayoyi ko solenoid.
3. Tsallake gwajin da'irar wutar lantarki: Wasu masu fasaha na iya ba su ɗauki lokaci don duba da'irar wutar lantarki ta solenoid. Rashin wutar lantarki a solenoid na iya zama saboda kuskure a cikin wutar lantarki, kuma yana da mahimmanci a duba wannan kafin yin tsalle zuwa ga ƙarshe game da kuskure a cikin solenoid kanta.
4. Rashin isasshen kulawa ga kayan aikin waya: Yin watsi da yanayin kayan aikin wayoyi na iya haifar da matsalolin da ba a gano ba. Wayoyi na iya lalacewa, karye, ko samun sako-sako da haɗin kai, wanda zai iya haifar da lambar P0444.
