P0027 Kutulutsa Valavu Yotulutsa Solenoid Circuit Range / Perf. B1

Mapepala a OBD-II DTC

Exhaust Valve Control Solenoid Circuit Out of Performance Range Bank 1

Kodi izi zikutanthauzanji?

Izi Diagnostic Trouble Code (DTC) ndi njira yofalitsira, zomwe zikutanthauza kuti imagwira ntchito pamagalimoto okhala ndi OBD-II kuphatikiza Toyota, VW, Ford, Dodge, Honda, Chevrolet, Hyundai, Audi, Acura, etc. Njira zokhazikitsira zimasiyana malinga ndi mtunduwo.

Pamagalimoto okhala ndi Variable Valve Timing (VVT), ma camshaft amayendetsedwa ndi ma hydraulic actuators omwe amadyetsedwa ndi makina amafuta a injini kudzera pa control solenoids kuchokera ku Engine Control Module/Powertrain Control Module (ECM/PCM). ECM/PCM yazindikira kuti banki 1 exhaust camshaft range of motion is out of specification or not working on command. Block 1 imatanthawuza mbali ya # 1 ya silinda ya injini - onetsetsani kuti mwayang'ana mbali yoyenera molingana ndi zomwe wopanga amapanga. The exhaust valve control solenoid nthawi zambiri imakhala pambali yotulutsa mpweya wambiri pamutu wa silinda.

Zindikirani. Khodi iyi imathanso kukhala yokhudzana ndi ma code P0078, P0079, kapena P0080 - ngati pali chilichonse mwa ma code awa, thetsani vuto la solenoid musanayambe kuzindikira vuto la dera/machitidwe. Khodi iyi ndi yofanana ndi ma code P0026, P0028 ndi P0029.

Zizindikiro

Zizindikiro za vuto la P0027 zitha kuphatikiza:

• Kuunikira kwa MIL (Chizindikiro Chosagwira)
• Kuthamangitsa koyipa kapena magwiridwe antchito a injini
• Kuchepetsa mafuta

zifukwa

Zomwe zingayambitse DTC P0027 zitha kuphatikiza:

• Mafuta otsika kapena mafuta owonongeka
• Mafuta otsekedwa
• Mphamvu yolamulira yoyendetsa
• Camshaft yolakwika
• Nthawi ya unyolo / lamba lotayirira kapena kusinthidwa molakwika
• Zowonongeka ECM / PCM

Mayankho otheka

Mafuta a Engine - Yang'anani mulingo wamafuta a injini kuti muwonetsetse kuti mtengo wamafuta a injini ndi wokwanira. Popeza ma actuators amagwira ntchito mopanikizika ndi mafuta, kuchuluka koyenera kwamafuta ndikofunikira kuwonetsetsa kuti VVT ​​imagwira ntchito bwino. Madzi odetsedwa kapena oipitsidwa angayambitse kuchuluka komwe kungayambitse kulephera kwa control solenoid kapena camshaft actuator.

Control Solenoid - The camshaft control solenoid ikhoza kuyesedwa kuti ipitirire ndi digito volt/ohmmeter (DVOM) pogwiritsa ntchito kuyeza kukana podula cholumikizira cha solenoid ndikuwona kukana kwa solenoid pogwiritsa ntchito (+) ndi (-) DVOM imatsogolera pa chilichonse. Pokwerera. Onetsetsani kuti kukana kwamkati kuli mkati mwazomwe wopanga, ngati alipo. Ngati kukana kuli mkati mwazomwe zimapangidwira, chotsani solenoid yolamulira kuti muwonetsetse kuti sichikuipitsidwa, kapena ngati pali kuwonongeka kwa mphete za o, kuchititsa kutaya kwa mafuta.

Camshaft Drive - The camshaft drive ndi makina oyendetsedwa ndi kuthamanga kwamkati kwa masika ndikuyendetsedwa ndi mafuta operekedwa ndi solenoid yowongolera. Ngati palibe kukakamiza kwamafuta komwe kukugwiritsidwa ntchito, amasinthira kukhala "otetezeka". Onani njira zomwe wopanga amapangira pochotsa choyimilira cha camshaft mu injini ya camshaft kuti muwonetsetse kuti palibe kutayikira komwe kungayambitse kutsika kwamafuta mu actuator supply/return hydraulic mizere kapena mkati mwa actuator yokha. Yang'anani unyolo wanthawi / lamba ndi zigawo zake kuti muwonetsetse kuti zikuyenda bwino ndikuyika pamalo oyenera pa zida za camshaft.

ECM/PCM - The ECM/PCM imalamula solenoid yolamulira pogwiritsa ntchito chizindikiro cha pulse-width modulated (PWM) kuti chiwongolere nthawi yotsegula / kutseka, zomwe zimabweretsa kulamulira kwamphamvu komwe kumagwiritsidwa ntchito kusuntha camshaft actuator. Ma graphical multimeter kapena oscilloscope amafunika kuti muwone chizindikiro cha PWM kuti muwonetsetse kuti ECM/PCM ikugwira ntchito bwino. Kuti muyese chizindikiro cha PWM, kutsogolera kwabwino (+) kumalumikizidwa ndi mbali ya pansi ya control solenoid (ngati iperekedwa ndi magetsi a DC, okhazikika) kapena mbali ya mphamvu ya solenoid yolamulira (ngati ili yokhazikika, kulamulira kwabwino) ndi choyipa (-) cholumikizidwa ndi maziko odziwika bwino. Ngati chizindikiro cha PWM sichikugwirizana ndi kusintha kwa injini RPM, ECM/PCM ikhoza kukhala vuto.

Zokambirana zokhudzana ndi DTC

Mukufuna thandizo lina ndi nambala yanu ya p0027?

Ngati mukufunabe thandizo ndi DTC P0027, lembani funso mu ndemanga pansipa pamutuwu.

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.
