P042F Exhaust Gas Recirculation Control Stuck Closed

OBD-II Faʻafitauli Faʻafitauli - P042F - Pepa Faʻamatalaga

P042F - Fa'atonuga le toe fa'aleleia o le kesi ua pipii tapunia

O le a le uiga o le DTC P042F?

Lenei o le Generic Transmission Diagnostic Trouble Code (DTC) e faʻaoga i OBD-II taʻavale. E mafai ona aofia ai, ae le faʻatapulaʻaina i, Ford, Chevrolet / GM / Cummins, Dodge / Ram, Isuzu, Pontiac, Toyota, BMW, Mercedes, ma isi A o le lautele, saʻo auala e mafai ona fesuiaʻi i le tausaga, ituaiga ma faʻatusa. ma faʻasalalauga faʻapitoa.

Afai o lau taʻavale na teuina se code P042F, o lona uiga o le powertrain control module (PCM) na maitauina se faʻafitauli ma le faʻamamaina o le kesi toe fuataʻiina (EGR) alatoto taofiofia.

I le tulaga o le P042F, o le alatoto foliga mai (mo le PCM) e pipii i le tapunia tulaga. O le igoa A e faasino i se tulaga faʻapitoa poʻo le tulaga o le faʻatonutonu-lalo o le EGR alatoto, o loʻo faʻamatalaina i lalo.

O le EGR system e gafa ma le faʻatagaina o le afi ona faʻaumatia nisi o suauʻu e leʻo faʻaola mai le faʻamamaina. E manaʻomia le toe faʻaaogaina o le kesi (EGR) e faʻaititia ai le leaga o le nitrogen oxide (NOx) mai le kesi ma afi.

O le ogatotonu o le faʻaaluina o le kesi faʻafouina faiga o se eletise faʻatonutonu alatoto (EGR) e tatala e faʻatagaina ai faʻaalu kasa e toe tafe i totonu o le afi faʻaaogaina. E faʻaaoga e le PCM mea e faʻaaoga ai mai le Throttle Position Sensor (TPS), Vehicle Speed ​​Sensor (VSS), ma le Crankshaft Position (CKP) e faʻamautinoa ai le taimi e talafeagai ai tulaga e tatala / tapuni le alatoto EGR.

O taʻavale ma lenei tulafono ua faʻatulagaina ma le faʻaaluina o le kesi faʻaaluina o alatoto i lalo. O le EGR lalo alatoto galue i laʻasaga faʻalagolago i le tatalaina throttle, afi avega ma taʻavale saosaoa.

I luga o nisi faʻataʻitaʻiga, o le tulaga o le EGR alatoto palu o loʻo mataʻitu foi e le PCM. Afai o le manaʻoga EGR alatoto tulaga (e PCM faʻatonuga) ese mai le tulaga tonu, o le P042F code o le a teuina ma se malform faʻailo moli (MIL) ono faʻamalamalamaina. O isi taʻavale faʻaaoga faʻamaumauga mai le Manifold Air Pressure (MAP) ma / poʻo le Differential Pressure Feedback (DPFE) EGR sensor e fuafua ai pe o le EGR valve o loʻo manaʻomia le tulaga (pe leai). O le tele o taʻavale o le a alu i le tele o uila afi (ma le faʻaletonu) ae le i faʻamalamalamaina le MIL.

Ata o le EGR alatoto:

O le a le ogaoga o lenei DTC?

Talu ai o le tapunia tulaga o le faʻamama kasa toe faʻafouina alatoto e le o se ogaoga faʻafitauli i tulaga o le faʻatonutonuina, o le P042F code mafai ona iloiloina i le vave avanoa.

O a nisi o fa'ailoga o le P042F code?

Faʻailoga o le P042F EGR faʻafitauli numera ono aofia ai:

• Masalo e leai ni faʻailoga ile faʻailoga lea
• Faʻapaʻitiiti teisi le lelei o le suauʻu

O a nisi o mafuaʻaga masani mo le tulafono?

Mafuaʻaga mo lenei P042F code ono aofia ai:

• Alatoto toe faʻaleleia o le kesi
• EGR solenoid / alatoto leaga
• Tatala pe puʻupuʻu taamilosaga i le uaea / fesoʻotaʻiga i le faʻataʻamilosaga faʻataʻamilomilo o le faʻaaluina o le kesi faʻaaluina o le tino
• Sensor DPFE leaga
• Sulu EGR alatoto tulaga sensor
• Sese PCM poʻo le PCM sese polokalame
• EGR fa'atonutonu alavai
• O lo'o tatala pe fa'apu'upu'u le fa'amau fa'amau e pulea le voluma EGR.
• Fa'aletonu le EGR fa'atonutonu le ta'amilosaga solenoid circuit
• EGR temperature sensor ma lona taamilosaga

O a nisi o P042F troubleshooting sitepu?

O se scanner scanner, digital volt / ohmmeter, ma se faʻamoemoe faʻatuatuaina o taʻavale faʻamatalaga o nisi ia o mea faigaluega manaʻomia e faʻailoaina le P042F code.

O se vaʻaiga vaʻaia uma EGR uaea ma fesoʻotaʻiga o le atoatoa harbinger o se P042F code faʻamaoniga. Faʻaleleia pe sui soʻo se vaega pala poʻo mu pe a manaʻomia.

Ona faʻafesoʻotaʻi lea o le scanner i le diagnostic port ma toe maua uma le teuina o tulafono ma faʻamaʻaina faʻafanua faʻamaumauga. Fai se tusi o lenei mea ona o le a aoga pe a fai o le P042F o se intermittent code. O lea kilia ia tulafono laiti ma faʻataʻitaʻi tulia le taʻavale ina ia mautinoa ua kilia le tulafono.

Afai ua kilia le tulafono, faʻafesoʻotaʻi le scanner ma matau le faʻamatalaga tafe. Siaki le manaʻoga EGR tulaga (masani fuaina o se pasene) ma le moni EGR tulaga faʻaalia luga o le faʻaaliga vaʻaia faʻaaliga. E tatau ona tutusa i totonu o nai milliseconds.

O le DPFE ma MAP sensors tatau ona atagia mai le tatalaina ma / pe tapuni o le EGR alatoto (tuu i le faitalia). Afai o iai le MAP poʻo le DPFE sensor code, e ono fesoʻotaʻi ma le P042F ma e tatau ona togafitia faʻapena.

Afai o le manaʻoga tulaga EGR eseʻese mai le tulaga tonu, mulimuli i fautuaga a le kamupanī mo le suʻega o EGR actuator solenoids ma le DVOM. O le faʻamama kasa recirculation tuʻu i lalo afuala mafai ona faʻaaogaina tele solenoids e faʻatosinaina ai le atoa vaega o faʻagaioiga o le faʻamama kasa toe faʻafouina faiga.

Afai e faʻaaoga se sensor DPFE i le faʻamamaina o le kesi toe faʻaleleia o le tino mo le taʻavale o loʻo fesiligia, mulimuli i faʻatonuga a le kamupanī mo le faʻataʻitaʻia. Fesoasoani pine laulau ma taʻavale faʻailoga ata o loʻo maua i lau taʻavale faʻamatalaga punaoa o le a fesoasoani i le suʻega. Sui sulu masei pe a manaʻomia ma toe faʻataʻitaʻi le faiga.

E mafai ona faʻaaogaina le DVOM e faʻataʻitaʻi ai taʻamilosaga taʻitasi i le va o le PCM fesoʻotaʻiga ma le EGR alatoto fesoʻotaʻiga. Uma fesoʻotaʻi pulea tatau ona momotu ese mai le matagaluega i luma tofotofoga.

• A maeʻa ona toe faʻaleleia, tuʻu le PCM i totonu o le sauniuniga auala ae le i faʻapea ua latou manuia.

Manaʻomia nisi fesoasoani ile lau P042F code?

Afai o loʻo manaʻomia pea se fesoasoani ile P042F mea sese, lafo se fesili i manatu o loʻo i lalo o lenei tusitusiga.

FAʻAALIGA. O lenei faʻamatalaga ua saunia mo na o faʻamatalaga faʻamatalaga. E le fuafuaina e faʻaaogaina o se faʻaleleia fautuaga ma matou te le tali atu mo soʻo se gaioiga e te faia i soʻo se taʻavale. Uma faʻamatalaga i luga o lenei '' upega tafaʻilagi puipuia e le puletaofia.
