P2186 # 2 Coolant Zazzabin Sensor Circuit Malfunction

Bayanan Bayani na OBD-II

Rashin aiki na mai sanyaya yanayin firikwensin kewaye No. 2

Mene ne wannan yake nufi?

Wannan Lambar Matsalar Bincike (DTC) lambar watsawa ce gaba ɗaya, wanda ke nufin ya shafi duk abin hawa tun 1996 (Ford, Hyundai, Kia, Mazda, Mercedes-Benz, da sauransu). Kodayake gabaɗaya a cikin yanayi, takamaiman matakan gyara na iya bambanta dangane da alama / ƙirar.

Lokacin da na haɗa mai karanta lambar ta zuwa abin hawa kuma na sami P2186 da aka adana, na san cewa tsarin kula da wutar lantarki (PCM) ya gano siginar da ba ta dace ba daga firikwensin # 2 injin coolant (ECT).

PCM tana sarrafa na'urori masu auna firikwensin ECT ta amfani da da'ira (yawanci volts biyar) wanda firikwensin ECT ya ƙare. Idan an yi amfani da firikwensin ECT daban (ɗaya don PCM da ɗaya don firikwensin zafin jiki), firikwensin da kansa galibi ƙirar waya biyu ce. Wayar farko tana ɗauke da wutar lantarki ta XNUMXV kuma waya ta biyu ita ce ta ƙasa. Na'urar firikwensin ECT yawanci firikwensin ƙima mara kyau ne, wanda ke nufin cewa yayin da zafin firikwensin ya ƙaru, juriya yana raguwa. Canjin juriya na firikwensin yana haifar da sauyin wutar lantarki a cikin kewaye, wanda PCM ta gane a matsayin canje-canje a cikin ECT. Idan PCM da firikwensin zafin jiki suna amfani da firikwensin ECT iri ɗaya, to, firikwensin zai zama waya XNUMX. Yana amsa ga zafin jiki kamar yadda na'urar firikwensin waya biyu, amma waya ɗaya tana ba da labari ga firikwensin kuma ɗayan wayar ta wuce shigarwar zuwa PCM. Yana da sauki, dama?

Kodayake wurin ECT zai bambanta daga mai ƙira zuwa mai ƙira, koyaushe za'a saka shi kai tsaye cikin tashar injin injin. Mutane da yawa masu kera motoci suna sanya firikwensin ECT a cikin toshewar silinda ko kan silinda, wasu suna murɗa shi zuwa ɗayan hanyoyin da ake amfani da ruwa mai ɗimbin yawa, wasu kuma suna sanya shi a cikin maɗaukakin gidan zafi.

Lokacin da aka birkitar da firikwensin ECT a cikin injin, tip na firikwensin, wanda ya ƙunshi thermistor, ya bazu cikin tashar sanyaya. Tare da injin yana gudana, mai sanyaya dole ne ya dinga kwarara ta cikin bakin. Yayin da yawan zafin jiki na injin yana ƙaruwa, haka ma thermistor ɗin ke cikin firikwensin ECT.

PCM yana amfani da zafin zafin injin don lissafin isar da mai, saurin rago, da lokacin ƙonewa. Shigar da firikwensin ECT yana da mahimmanci saboda dole ne tsarin sarrafa injin ya yi aiki daban kamar yadda zafin zafin injin ya canza daga zafin yanayi zuwa sama da digiri 220 na Fahrenheit. PCM kuma yana amfani da shigarwar firikwensin ECT don kunna fanka mai sanyaya lantarki.

Idan PCM ta karɓi siginar shigarwa daga firikwensin ECT # 2 waɗanda ke ɓarna ko ɓata lokaci don takamaiman lokaci kuma a ƙarƙashin wasu yanayi, za a adana lambar P2186 kuma fitilar alamar rashin aiki (MIL) na iya haskakawa.

Misalin injin ECT injin coolant temperature

Lura. Wannan DTC asali iri ɗaya ne da P0119, duk da haka bambancin da wannan DTC shine cewa yana da alaƙa da ECT # 2 firikwensin kewaye. Don haka, motocin da ke da wannan lambar suna nufin suna da firikwensin ECT guda biyu. Tabbatar cewa kuna bincikar da'irar firikwensin daidai.

Tsanani da alamu

Yayin da firikwensin ECT ke taka muhimmiyar rawa wajen sarrafa injin, dole ne a magance lambar P2186 cikin gaggawa.

Alamomin lambar P2186 na iya haɗawa da:

• M injin da ke bacci yayin fara sanyi
• Haushi ko tuntuɓe yayin hanzarta
• Ƙanshin ƙanshi mai ƙarfi, musamman lokacin fara sanyi
• Injin zafi mai yuwuwa
• Fan mai sanyaya aiki yana ci gaba ko baya aiki kwata -kwata

Mai yiwuwa sanadin wannan lambar injin ya haɗa da:

• Low engine coolant matakin
• Kuskuren thermostat
• Raunin firikwensin # 2 ECT
• Buɗe ko gajeriyar kewaya na wayoyi da / ko masu haɗawa a cikin da'irar firikwensin No. 2 ECT

Hanyoyin bincike da gyara

Kyakkyawan farawa shine koyaushe bincika takaddun sabis na fasaha (TSB) don takamaiman abin hawa. Matsalar ku na iya zama sanannen batun tare da sanannen gyaran masana'anta kuma yana iya adana ku lokaci da kuɗi yayin bincike.

Lokacin fuskantar lambar bincike na P2186, Ina son samun na'urar sikelin bincike mai dacewa, volt / ohmmeter (DVOM), thermometer infrared, da ingantacciyar hanyar bayanan abin hawa (kamar Duk Data DIY) a hannu.

Ina so in haɗa na'urar daukar hotan takardu zuwa soket na binciken abin hawa, dawo da DTC da aka adana da daskare bayanan firam, da rubuta wannan bayanin don fara bincike. Yanzu share lambobin.

Sannan zan yi duba na gani na wayoyi da masu haɗa na'urar firikwensin ECT # 2. Gyara ko maye gurbin wayoyin da aka ƙone ko lalace da / ko masu haɗawa kamar yadda ake buƙata kuma sake gwada tsarin. Idan ba a sake saita P2186 nan da nan ba, yana iya zama na lokaci -lokaci. Fitar da kullun har sai PCM ta shiga yanayin shirye-shiryen OBD-II ko an share lambar. Idan an sake saita P2186, ci gaba da bincike.

Sake haɗa na'urar daukar hotan takardu kuma kira kwararar data dace. Rage rafin bayanai don kawai bayanai masu dacewa kawai ake nunawa kuma amsar bayanai ta fi sauri. Kula da zazzabi da ƙarfin lantarki na ECT # 2 firikwensin don rashin aiki ko rashin daidaituwa. PCM za ta tsinkayi wannan azaman siginar shiga tsakani daga da'irar firikwensin ECT. Idan akwai banbanci, duba mai haɗa firikwensin ECT don lalata. Duba wayoyi a kusa da manyan fitowar manifolds / manifolds (ɗan gajeren lokaci zuwa ƙasa) da ƙuƙwalwa ko ɓoyayyen maƙallan haɗin kan firikwensin zafin jiki mai sanyaya. Gyara ko maye gurbin abubuwan da ke da lahani kamar yadda ya cancanta.

Ƙananan injin coolant matakin na iya ba da gudummawa ga lambar P2186. Lokacin da injin ya yi sanyi, cire babban matsin lamba kuma tabbatar injin ya cika da injin da aka ba da shawarar. Idan matakin mai sanyaya injin ya ragu da fiye da 'yan lita huɗu, bincika injin ɗin don kwararar coolant. Don wannan, ma'aunin matsa lamba a cikin tsarin sanyaya na iya zama da amfani. Gyaran magudanar ruwa idan ya cancanta, cika tsarin tare da sanyaya mai dacewa kuma sake duba tsarin.

Idan an gano na'urar firikwensin # 2 ECT (akan nunin kwararar bayanai na na'urar daukar hotan ta) kamar yayi kasa ko babba, yi zargin kuskure ne. Ta amfani da DVOM, bincika juriya na firikwensin ECT kuma kwatanta sakamakon ku tare da shawarwarin masana'anta. Sauya firikwensin idan bai cika buƙatun ba.

Idan firikwensin ECT # 2 yana da ɗan ƙarami ko babba, yi amfani da ma'aunin zafi da sanyio don samun ainihin ECT. Kwatanta siginar firikwensin ECT da aka nuna a cikin rafin bayanai tare da ainihin ECT kuma jefar da firikwensin idan basu dace ba.
