P2149 Fuel Injector Gulu B Kusagwira / Kutsegula

P2149 Fuel Injector Gulu B Kusagwira / Kutsegula

Mapepala a OBD-II DTC

Mafuta Injector Gulu B Dera / Tsegulani

Kodi izi zikutanthauzanji?

Imeneyi ndi nambala yovuta yoyeza matenda (DTC) ndipo imagwiritsidwa ntchito kwambiri pamagalimoto a OBD-II. Izi zitha kuphatikizira koma sizimangokhala magalimoto ochokera ku Dodge Ram (Cummins), GMC Chevrolet (Duramax), VW, Audi, Ford (Powerstroke), Mercedes Sprinter, Peugeot, Alfa Romeo, Nissan, Saab, Mitsubishi, ndi zina. Zingasiyane kutengera chaka chakapangidwe, kapangidwe, kapangidwe kake ndi kasinthidwe kake.

Ma jakisoni wamafuta ndi gawo limodzi lamafuta operekera mafuta m'galimoto zamakono.

Machitidwe operekera mafuta amagwiritsa ntchito zigawo zingapo kuyang'anira ndikuwunika kuchuluka, nthawi, kukakamiza, ndi zina. Makinawa akuphatikizidwa ndi ECM (Engine Control Module). Ma jakisoni wamafuta adayambitsidwa kuti alowe m'malo mwa carburetor chifukwa ma jakisoni ndiwothandiza komanso ogwira ntchito poyang'anira mafuta. Zotsatira zake, athandizanso kugwiritsa ntchito mafuta mwaluso, ndipo mainjiniya akupanga njira zabwino zowonjezeretsera kapangidwe kake.

Popeza kuti atomization ya injector imayendetsedwa pakompyuta, mphamvu yamagetsi ndiyofunikira pakupereka mafuta kuzitsulo. Komabe, vuto mu unyolo uwu limatha ndipo / kapena limayambitsa mavuto akulu pazovuta zina ndi zina.

Kalata ya "B" m'ndondomeko iyi imagwiritsidwa ntchito posiyanitsa vuto lomwe lili mdera liti. Kuti mudziwe momwe izi zikugwirira ntchito pagalimoto yanu, muyenera kufunsa zaumisiri wopanga. Zitsanzo zina zakusiyana ndi ma nozzles: banki 1, 2, etc.

ECM imayatsa nyali yowonongera (nyali yowonongera) yokhala ndi nambala P2149 ndi / kapena ma foni ofanana (P2150, P2151) ikayang'anira vuto pamagetsi amagetsi opangira ma jakisoni wamafuta ndi / kapena madera awo. Tiyenera kudziwa kuti ma jekeseni wamafuta amayendetsedwa pafupi kwambiri ndi kutentha kwakukulu. Chifukwa chakupezeka kwa malamba, samakhala olimba pakuwonongeka kwakuthupi. Ndili ndi malingaliro, ndinena kuti nthawi zambiri limakhala vuto lamakina.

P2149 Gulu B jakisoni wamafuta oyendetsa / dera lotseguka limagwira pamene ECM izindikira kutseguka kapena kusowa bwino kwamagetsi opangira mafuta.

Kodi kuuma kwa DTC kumeneku ndi kotani?

Wovuta kwambiri, ndinganene. M'munda, timatcha kusowa kwamafuta osakanikirana "dziko lowonda". Injini yanu ikamagwira ntchito yosakanikirana ndi mafuta, mumakhala pachiwopsezo chowononga injini posachedwa komanso patali. Ndili ndi malingaliro, nthawi zonse muziyang'anira kukonza kwa injini yanu. Pali khama pano, choncho tiyeni injini zathu ziziyenda bwino komanso moyenera. Kupatula apo, amatikoka kuti atinyamule tsiku lililonse.

Kodi zina mwazizindikiro za code ndi ziti?

Zizindikiro za vuto la P2149 zitha kuphatikiza:

• Magwiridwe a injini osakhazikika
• Khutitsani
• Kuchepetsa mafuta
• Osakhazikika osagwira
• Utsi wambiri
• Phokoso la injini
• Kupanda mphamvu
• Simungathe kukwera mapiri otsetsereka
• Kuchepetsa kuyankha kwamphamvu

Kodi zina mwazomwe zimayambitsa codezi ndi ziti?

Zifukwa za P2149 zamagetsi zamagetsi zamagetsi zamagetsi zimatha kuphatikiza:

• Ma jakisoni opunduka kapena owonongeka
• Zowonongeka zama waya
• Kulephera kwa zingwe zamkati
• Vuto lamkati la ECM
• Vuto cholumikizira

Kodi ndi njira ziti zina zothetsera P2149?

Gawo loyambira # 1

Gawo loyamba lolimbikitsidwa ndikuzindikira "gulu" la masensa omwe opanga akulankhula. Ndi chidziwitsochi, mudzatha kupeza malo enieni a jekeseni (ma) ndi maulendo awo. Izi zingafunike kuchotsedwa kwa zovundikira zamainjini zambiri ndi/kapena zida kuti mupeze mawonekedwe (ngati kuli kotheka). Onetsetsani kuti mwayang'ana chingwe cha mawaya osweka. Chotsekereza chilichonse chomwe chatha chiyenera kukonzedwa bwino ndi machubu ochepetsa kutentha kuti apewe zovuta zina kapena zamtsogolo.

Gawo loyambira # 2

Nthawi zina madzi ndi / kapena zamadzimadzi zimatha kukakamira kuzigwa zomwe zimayikidwa ma nozzles. Izi zimawonjezera mwayi woti zolumikizira zamagetsi, pakati pamagetsi ena, zitha kuwonongeka mwachangu kuposa zachilendo. Onetsetsani kuti zonse zili bwino ndipo ma tabu pazolumikizira akusindikiza bwino kulumikizana. Khalani omasuka kugwiritsa ntchito njira zotsukira zamagetsi kuti zonse zizilowa ndikutuluka bwino, osanenapo zowonjezera zamagetsi zolumikizana ndi izi.

Gawo loyambira # 3

Fufuzani kuti mupitirize kutsatira ndondomeko yothetsera mavuto mu buku lanu lothandizira galimoto. Chitsanzo chimodzi ndikutulutsa magetsi kuchokera ku ECM ndi injini yamafuta kenako ndikugwiritsa ntchito multimeter kuti muwone ngati mawaya akugwira bwino ntchito.

Chiyeso chimodzi chomwe ndimakonda kuchita kuti ndidziwe mwachangu ngati pali chotseguka muwaya inayake chomwe chingathandize ndi code P2149 ndikuyesa "kuyesa kopitilira". Khazikitsani ma multimeter kukhala RESISTANCE (omwe amadziwikanso kuti ohms, impedance, etc.), kukhudza mbali imodzi kumapeto kwa dera, ndi mapeto ena. Mtengo uliwonse wapamwamba kuposa momwe umafunira ukhoza kusonyeza vuto mu dera. Vuto lililonse pano liyenera kuzindikirika potsata waya womwe mukuwunika.
