Kodi DTC P042F imatanthauza chiyani?

Iyi ndi nambala yovuta yotengera matenda (DTC) yogwiritsidwa ntchito pamagalimoto a OBD-II. Izi zingaphatikizepo, koma sizingokhala ku, Ford, Chevrolet / GM / Cummins, Dodge / Ram, Isuzu, Pontiac, Toyota, BMW, Mercedes, ndi zina zambiri. ndi kasinthidwe kasinthidwe.

Ngati galimoto yanu yasunga nambala ya P042F, zikutanthauza kuti powertrain control module (PCM) yazindikira vuto pamagalimoto oyendetsera mpweya (EGR).

Pankhani ya P042F, valavu imawonekera (kuti PCM) ikomereke. Mayina A amatanthauza malo kapena gawo lokhazikika pa valavu ya EGR, yomwe yafotokozedwa pansipa.

Makina a EGR ali ndi udindo wololeza injini kuti idye mafuta osayaka omwe atenthedwe. Kutulutsa mpweya wamafuta (EGR) ndikofunikira kuti muchepetse kuchuluka kwa nayitrogeni okusayidi (NOx) kuchokera ku mafuta ndi injini za dizilo.

Pakatikati pa mpweya wamagetsi wamagetsi ndi valavu yamagetsi (EGR) yomwe imatseguka kuti mpweya wotulutsa mpweya ubwererenso mu injini. PCM imagwiritsa ntchito zolowetsa kuchokera ku Throttle Position Sensor (TPS), Vehicle Speed ​​Sensor (VSS), ndi sensa ya Crankshaft Position (CKP) kuti mudziwe nthawi yoyenera kutsegula / kutseka valavu ya EGR.

Magalimoto omwe ali ndi code iyi amakhala ndi mpweya wotaya mpweya wotsekemera. Valavu yotsika ya EGR imagwira ntchito m'magawo kutengera kutseguka kwapakhosi, kuchuluka kwa injini komanso kuthamanga kwamagalimoto.

Pa mitundu ina, PCM imawunikiranso poyika valavu plunger. Ngati malo ovomerezeka a EGR (mwa lamulo la PCM) amasiyana ndi momwe alili, nambala ya P042F idzasungidwa ndipo nyali yowunikira (MIL) itha kuwunikira. Magalimoto ena amagwiritsa ntchito deta kuchokera ku Manifold Air Pressure (MAP) ndi / kapena Differential Pressure Feedback (DPFE) EGR sensor kuti adziwe ngati valavu ya EGR ili pamalo oyenera (kapena ayi). Magalimoto ambiri amatenga mayendedwe angapo (osagwira bwino) MIL isanaunikire.

Kodi kuuma kwa DTC kumeneku ndi kotani?

Popeza kutsekedwa kwa mpweya wamagetsi wamagetsi sikuli vuto lalikulu pankhani ya kuwongolera, nambala ya P042F ikhoza kuwunikidwanso mwachangu.

Kodi zina mwazizindikiro za nambala ya P042F ndi ziti?

Zizindikiro za vuto la P042F EGR zitha kuphatikizira izi:

• Zowonjezera sipadzakhala zizindikiro ndi code iyi
• Kuchepetsa mafuta pang'ono

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za code iyi ya P042F zitha kuphatikizira izi:

• Opunduka utsi vavu recirculation vavu
• EGR solenoid / valve yolakwika
• Dera lotseguka kapena lalifupi mu zingwe / zolumikizira mu gawo loyang'anira makina otulutsa utsi
• Choyipa cha DPFE sensor
• Wopunduka EGR vavu malo kachipangizo
• Zolakwika za PCM kapena PCM zolakwika
• EGR flow flow valve valve
• EGR voliyumu yowongolera solenoid harness ndi yotseguka kapena yofupikitsidwa.
• Zolakwika EGR otaya kuwongolera dera solenoid dera
• EGR sensor kutentha ndi kuzungulira kwake

Ndi njira ziti zomwe zingasokoneze P042F?

Chojambulira matenda, digito volt / ohmmeter, komanso gwero lodalirika lazidziwitso zamagalimoto ndi zina mwazida zofunika kuti mupeze nambala ya P042F.

Kuyang'ana kwamawonekedwe onse a EGR ndi zolumikizira ndi harbinger woyenera wa kachilombo ka P042F. Konzani kapena sinthanitsani chilichonse chokhala ndi dzimbiri kapena chowotcha ngati kuli kofunikira.

Kenako gwirizanitsani chojambulira ndi doko lazidziwitso ndikutenga ma nambala onse osungidwa ndikuwumitsa chimango. Lembani izi chifukwa zingakhale zothandiza ngati P042F ndi nambala yapakatikati. Tsopano chotsani ma code ndikuyesa kuyendetsa galimoto kuti muwonetsetse kuti nambala yanu yachotsedwa.

Ngati codeyo yatsukidwa, gwirizanitsani sikaniyo ndikuwonera momwe ikuyendera. Onetsetsani malo omwe mukufuna a EGR (omwe nthawi zambiri amayeza ngati gawo) ndi malo enieni a EGR omwe akuwonetsedwa pakuwonetsera kwa deta. Ayenera kukhala ofanana mkati mwa millisecond ochepa.

Masensa a DPFE ndi MAP akuyenera kuwonetsa kutsegula ndi / kapena kutseka kwa valavu ya EGR (posankha). Ngati manambala a MAP kapena DPFE alipo, atha kulumikizidwa ndi P042F ndipo amayenera kuchitidwa motero.

Ngati malo omwe mukufuna a EGR akusiyana ndi momwe alili, tsatirani malingaliro a wopanga kuti ayesere ma EGR actuator solenoids ndi DVOM. Mpweya wotsekemera wamafuta wotsitsa amatha kugwiritsa ntchito ma solenoids angapo kuti akhudze magwiridwe antchito onse a mpweya wamafuta.

Ngati sensa ya DPFE imagwiritsidwa ntchito pamafuta oyimitsa mpweya wa galimoto yomwe ikufunsidwayo, tsatirani malingaliro a wopanga kuti ayesedwe. Ma tebulo olumikizirana ndi pini yolumikizira ndi zingwe zolumikizira magalimoto zomwe zimapezeka pagalimoto yanu zithandizira pakuyesedwa. Sinthanitsani masensa olakwika ngati kuli kofunikira ndikuyesanso makinawo.

DVOM itha kugwiritsidwa ntchito kuyesa ma circuits amodzi pakati pa cholumikizira cha PCM ndi cholumikizira cha EGR valve. Oyang'anira onse olumikizidwa ayenera kuchotsedwa mdera asanakayesedwe.

• Kukonzanso kukamalizidwa, lolani PCM kuti ikhale yokonzeka asanaganize kuti achita bwino.

Mukufuna thandizo lina ndi nambala yanu ya P042F?

Ngati mukufunabe thandizo ndi nambala ya P042F, lembani funso m'mawu pansipa.

ZINDIKIRANI. Izi zimaperekedwa kuti zidziwitse zokha. Sikuti tizigwiritsa ntchito ngati malingaliro okonzanso ndipo sitili ndi udindo pazomwe mungachite pagalimoto iliyonse. Zomwe zili patsamba lino ndizotetezedwa ndi zovomerezeka.
