P2186 # 2 Ukungasebenzi Kokushisa Kwenzwa Yesekethe Yesekethe

P2186 # 2 Ukungasebenzi Kokushisa Kwenzwa Yesekethe Yesekethe

Idatha ye-OBD-II DTC

Ukungasebenzi kahle kwesipholisi senzwa yokushisa epholile No.2

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) iyikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza kuzo zonke izimoto kusukela ngo-1996 (Ford, Hyundai, Kia, Mazda, Mercedes-Benz, njll.). Noma kujwayelekile, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Lapho ngixhuma i-code reader yami emotweni bese ngithola i-P2186 egciniwe, ngiyazi ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole isignali engena ngaphakathi evela kunzwa ye- # 2 engine coolant temperature (ECT) sensor.

I-PCM ilawula izinzwa ze-ECT isebenzisa i-reference circuit (imvamisa ama-volts amahlanu) enqanyulwa inzwa ye-ECT. Uma kusetshenziswa izinzwa ezihlukene ze-ECT (eyodwa ye-PCM neyodwa yenzwa yokushisa), inzwa ngokwayo ngokuvamile iwumklamo wezintambo ezimbili. Intambo yokuqala iphethe i-voltage yesithenjwa engu-XNUMXV kanti intambo yesibili intambo yaphansi. Inzwa ye-ECT ngokuvamile iyinzwa ye-coefficient engalungile, okusho ukuthi njengoba izinga lokushisa lenzwa likhula, ukumelana kuncipha. Ushintsho ekumelaneni nezinzwa luphumela ekuguquguqukeni kwe-voltage kusekethe, i-PCM ekubona njengezinguquko ku-ECT. Uma i-PCM nenzwa yezinga lokushisa zisebenzisa inzwa efanayo ye-ECT, inzwa izoba yizintambo ezi-XNUMX. Iphendula ezingeni lokushisa ngendlela efanayo nenzwa enezintambo ezimbili, kodwa ucingo olulodwa lunikeza okokufaka kunzwa kanti olunye ucingo ludlulisela okokufaka ku-PCM. Kulula, akunjalo?

Yize indawo ye-ECT izohluka kusuka kumkhiqizi kuya kumkhiqizi, iyohlala ifakwa ngqo esiteshini sokupholisa injini. Ama-automaker amaningi abeka inzwa ye-ECT ku-cylinder block noma isilinda ekhanda, abanye bayishutheka kwelinye lamaphaseji apholile amaningi, kanti abanye bakubeka endlini ye-thermostat.

Lapho inzwa ye-ECT ifakwa enjinini, ichopho lenzwa, eliqukethe i-thermistor, liphuma lingene esiteshini esipholisayo. Ngenjini esebenza, i-coolant kufanele igeleze njalo ngethiphu. Njengoba izinga lokushisa kwenjini liphakama, kanjalo ne-thermistor ngaphakathi kwenzwa ye-ECT.

I-PCM isebenzisa ukushisa kwenjini ukubala ukulethwa kukaphethiloli, isivinini esingenzi lutho, nesikhathi sokushisa. Okokufaka inzwa ye-ECT kubalulekile ngoba uhlelo lokuphathwa kwezinjini kufanele lusebenze ngokuhlukile njengoba izinga lokushisa lenjini liguquka ukusuka emazingeni okushisa ambient kuye ngaphezu kwama-220 degrees Fahrenheit. I-PCM ibuye isebenzise okokufaka kwenzwa ye-ECT ukuvula ifeni yokupholisa kagesi.

Uma i-PCM ithola amasiginali wokufaka kusuka kunzwa ye-ECT # 2 engaguquguquki noma eyemuva kwesikhathi esethiwe futhi ezimweni ezithile, ikhodi engu-P2186 izogcinwa futhi isibani sesikhombisi esingasebenzi kahle (MIL) singakhanyisa.

Isibonelo se-ECT engine sensor coolant sensor

Qaphela. Le DTC ngokuyisisekelo iyefana ne-P0119, kepha umehluko ngale DTC ukuthi ihlobene nesekethe yezinzwa ze-ECT # 2. Ngakho-ke, izimoto ezinale khodi zisho ukuthi zinezinzwa ezimbili ze-ECT. Qiniseka ukuthi uthola ukuthi isekhethi yenzwa efanele yini.

Ubunzima nezimpawu

Ngenxa yokuthi inzwa ye-ECT ibamba iqhaza elibaluleke kangaka ekuphatheni izinjini, ikhodi ye-P2186 idinga ukulungiswa ngokushesha.

Izimpawu zekhodi ye-P2186 zingafaka:

• Injini elukhuni idling ngesikhathi sokuqala okubandayo
• Ukungabaza noma ukukhubeka lapho ushesha
• Iphunga elinamandla lokukhipha, ikakhulukazi ngesikhathi sokuqala kubanda
• Ukushisa kwe-injini kungenzeka
• I-fan yokupholisa isebenza ngokuqhubekayo noma ayisebenzi nhlobo

izizathu

Izimbangela ezingaba khona zale khodi yenjini zifaka:

• Izinga lokupholisa injini ephansi
• I-thermostat engalungile
• Inzwa engaphelele # 2 ECT
• Isifunda esivulekile noma esifushane se-wiring kanye / noma izixhumi kusekethe yezinzwa No. 2 ECT

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Lapho ngibhekene ne-P2186 code diagnostic code, ngithanda ukuba nesikena esifanelekile sokuxilonga, i-digital volt / ohmmeter (i-DVOM), i-infrared thermometer, nomthombo othembekile wolwazi lwemoto (njenge-All Data DIY) esandleni.

Ngithanda ukuxhuma isithwebuli kusokhethi yokuxilonga imoto, ngithole ama-DTC agciniwe futhi ngifrize idatha yohlaka, bese ngibhala lolu lwazi phansi ukuqala ukuxilonga. Manje sula amakhodi.

Ngabe ngenza ukuhlolwa okubonakalayo kwe-ECT # 2 wiring sensor nezixhumi. Lungisa noma buyisela izintambo ezishile noma ezonakele kanye / noma izixhumi njengoba kudingeka bese uphinde uzame uhlelo. Uma i-P2186 ingasethiwe kabusha ngokushesha, ingahle ibe ngezikhathi ezithile. Shayela ngokujwayelekile kuze kube yilapho i-PCM ingena kumodi elungile ye-OBD-II noma ikhodi isuliwe. Uma i-P2186 isethwe kabusha, qhubeka nokuxilonga.

Xhuma kabusha isithwebuli bese ucele ukusakazwa kwedatha okufanele. Nciphisa ukusakazwa kwedatha ukuze kuboniswe idatha efanelekile kuphela futhi impendulo yedatha ishesha kakhulu. Bheka izinga lokushisa namandla we-ECT # 2 inzwa yokuphazamiseka noma ukungahambelani. Lokhu kuzohunyushwa yi-PCM njengezimpawu eziphakathi nezikhathi ezivela kumjikelezo we-ECT sensor. Uma kunokungafani, hlola isixhumi sesizweli se-ECT sokugqwala. Bheka i-wiring eduzane nezinqwaba zokushisa okushisa okushisayo Lungisa noma shintsha izinto ezinesici njengoba kudingeka.

Izinga elipholisa injini elincane lingafaka nekhodi engu-P2186. Lapho injini seyipholile, susa ikepisi yengcindezi ephezulu bese uqinisekisa ukuthi injini igcwaliswa ngesipholisi esinconywayo. Uma izinga lokupholisa injini lehle ngaphezu kwamalitha ambalwa, hlola injini ngokuvuza okupholile. Ngenxa yalokhu, igeji yengcindezi ohlelweni lokupholisa ingahle ilusizo. Lungisa ukuvuza uma kunesidingo, gcwalisa isistimu ngesipholisi esifanelekile bese uqala kabusha uhlelo.

Uma inzwa engu- # 2 ye-ECT itholakele (kusibonisi sokuhamba kwedatha yesithwebuli) njengesiphansi kakhulu noma siphezulu kakhulu, sola ukuthi sinesici. Usebenzisa i-DVOM, hlola ukumelana kwenzwa ye-ECT bese uqhathanisa imiphumela yakho nezincomo zomkhiqizi. Miselela inzwa uma ingahlangabezani nezimfuneko.

Uma inzwa ye-ECT # 2 ibonakala iphansi kancane noma iphakeme, sebenzisa i-thermometer ye-infrared ukuthola i-ECT yangempela. Qhathanisa isignali yenzwa ye-ECT ekhonjiswe ekusakazweni kwedatha ne-ECT yangempela bese ulahla inzwa uma ingafani.

Amanothi wokuxilonga angeziwe:

• Ngaphambi kokuzama ukuxilonga i-P2186, qiniseka ukuthi injini igcwele isibandisi futhi i-thermostat isebenza kahle.
• Amanye amakhodi wezinzwa ze-ECT kanye namakhodi wokushisa we-engine angahambisana nalolu hlobo lwekhodi.
• Xilonga futhi ulungise amanye amakhodi ahlobene ne-ECT ngaphambi kokuthola i-P2186.

Amakhodi wesifunda we-ECT ahambisanayo: P0115, P0116, P0117, P0118, P0119, P0125, P0128, P2182, P2183, P2184, P2185

Izingxoxo ezihlobene ze-DTC

• Okwamanje azikho izihloko ezihlobene ezinkundleni zethu. Thumela isihloko esisha esithangamini manje.

Udinga usizo olwengeziwe ngekhodi le-p2186?

Uma usadinga usizo nge-DTC P2186, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
