P044E Exhaust Gas Recirculation Sensor C Ukungasebenzi kahle Kwesifunda

Idatha ye-OBD-II DTC

Isekhethi yenzwa ye-EGR "C" enesikhashana / engazinzile

Kusho ukuthini lokhu?

Le yi-Generic Transmission Diagnostic Trouble Code (DTC), okusho ukuthi isebenza kukho konke ukwenziwa / amamodeli kusuka ngo-1996 kuye phambili. Noma kunjalo, izinyathelo ezithile zokuxazulula inkinga zingahluka kusuka emotweni kuya emotweni.

Ikhodi yenkinga ye-P044E On-Board Diagnostic (OBD) iyikhodi yenkinga evamile ebhekisela kunkinga yesikhashana noma eqhubekayo kusekethi ye-Exhaust Gas Recirculation (EGR) valve "C".

I-valve yokukhipha igesi yokukhipha isetshenziselwa ukunikeza inani elilawulwayo legesi yokukhipha ekuphindaphindeni. Inhloso ukugcina ukushisa kwekhanda lesilinda kungaphansi kwama-2500 degrees Fahrenheit. Ama-nitrate e-oksijeni (Nox) akhiwa lapho amazinga okushisa enyuka ngaphezu kwama-2500 degrees Fahrenheit. UNox ubhekele ukungcola kwentuthu nomoya.

Ikhompuyutha yokulawula, kungaba imojula yokulawula i-powertrain (PCM), noma imojula yokulawula kagesi (ECM) ithole ivolthi yesiginali ephansi ngokungavamile, ephezulu, noma engekho. Bheka imanuwali yokulungisa yomkhiqizi ukuze unqume ukuthi iyiphi inzwa ethi "C" efakwe emotweni yakho ethile.

Kusebenza kanjani ukubuyiswa kwegesi yokukhipha

I-DTC P044E ibhekisela enkingeni efanayo kuzo zonke izimoto, nokho kunezinhlobo eziningi ze-EGR, izinzwa nezindlela zokuvula. Okufanayo kuphela ukuthi zonke zikhipha amagesi e-exhaust ku-manifold yokuthatha ukuze kuphole ikhanda lesilinda.

Ukuthela igesi yokukhipha injini enjini ngesikhathi esingalungile kuzonciphisa amandla wehhashi futhi kubangele ukuthi idume noma itafula. Unalokhu engqondweni, izinhlelo zamakhompiyutha zivula i-EGR kuphela ku-injini rpm ngaphezulu kuka-2000 bese ivala ngaphansi komthwalo.

Inzwa ehambelana negesi yokukhipha igesi "C" amakhodi:

• I-P044A Exhaust Gas Recirculation Sensor C Circuit
• I-P044B Exhaust Gas Recirculation Sensor "C" Ibanga Lesekethe / Ukusebenza
• P044C Inkomba ephansi yenzwa "C" yohlelo lokukhipha igesi qeda
• P044D Inani eliphakeme lenzwa "C" yohlelo lokukhipha kabusha igesi

izimpawu

Izimpawu zincike esimweni senaliti yokukhipha igesi yokukhipha ngesikhathi sephutha.

• Maduze ukukhanya kwenjini yesevisi kuzokhanya futhi ikhodi ye-OBD engu-P044E izosethwa. Ukwengeza, ikhodi yesibili ingasethwa ehlobene nokuhluleka kwenzwa ye-EGR. I-P044C ibhekisela ku-voltage yenzwa ephansi futhi i-P044D ibhekisela esimweni se-voltage ephezulu.
• Uma iphini le-EGR livinjwe kancane, imoto ngeke ivume noma itafule.
• Ukukhala ngokungqongqoza kuzwakala ngaphansi komthwalo noma nge-rpm ephezulu
• Azikho izimpawu

Izizathu ezingenzeka

• Inzwa yokukhipha igesi yokukhipha engaphelele "C".
• Izintambo zokubophela izintambo ezinenkinga enzwa
• Iphini le-EGR linamathele endaweni evaliwe futhi ukwakheka kwekhabhoni kuyivimbela ekuvulekeni
• Ukuntuleka komshini ku-solenoid yegesi yokukhipha igesi.
• I-solenoid yokubuyisela kabusha igesi engalungile
• Exhaust igesi recirculation isikhundla inzwa kunephutha
• Inzwa yokuphendula ingcindezi enephutha.

Izinqubo zokulungisa

Wonke ama-valve e-EGR anento eyodwa afana ngayo - aphinde ajikeleze amagesi e-exhaust asuka ku-exhaust system aye ku-multifolded. Ngaphezu kwalokho, bahluke ezindleleni zokulawula ukuvulwa kwenaliti nokunquma isikhundla sayo.

Izinqubo ezilandelayo zokulungisa yizinkinga ezivame kakhulu ezibangela ukwehluleka okuningi kwe-EGR. Uma i-harness noma inzwa inephutha, ibhukwana lesevisi liyadingeka ukunquma izinqubo ezifanele zokukhomba nokuhlonza izintambo.

Yazi ukuthi i-wiring iyahluka kusuka kumkhiqizi kuya kumkhiqizi, futhi amakhompyutha awaphenduli kahle uma kucutshungulwa ucingo olungalungile. Uma uhlola ucingo olungelona futhi uthumele amandla amaningi ngokweqile kunqamula i-terminal yekhompyutha yokufaka inzwa, ikhompyutha izoqala ukushisa.

Ngasikhathi sinye, uma isixhumi esingalungile sinqanyuliwe, ikhompyutha ingalahlekelwa yizinhlelo, ikwenze kungakwazi ukuqala injini kuze kube yilapho umthengisi enza kabusha ikhompyutha.

• I-P044E ikhombisa inkinga kusekethi B, ngakho-ke hlola isixhumi senzwa ye-EGR ukuze uthole ukugqwala, amatheminali agobile noma akhishiwe, noma ukuxhuma okuxekethile. Susa noma yikuphi ukugqwala futhi ufake kabusha isixhumi.
• Nqamula isixhumi sikagesi bese ususa uhlelo lokuphinda usebenzise igesi. Bheka itheku lokukhipha igesi lokukhipha ugesi nge-coke. Susa i-coke uma kunesidingo ukuze inaliti ihambe ngokushelela phezulu nangaphansi.
• Bheka ulayini wokuhlanza osuka ohlelweni lokukhipha igesi qeda ku-solenoid bese uyishintsha uma kutholakala noma yikuphi ukukhubazeka.
• Bheka isixhumi sombane se-solenoid ukuthola ukugqwala noma ukukhubazeka.
• Uma imoto iyiFord, landela amapayipi amabili wokukhipha opholile kusuka ohlelweni lokukhipha igesi qeda kunzwa yokuphindaphindeka kwengcindezi yokuphendula igesi (DPFE) ngemuva kokuphindaphindeka.
• Hlola amapayipi amabili okucindezela ukugqwala. Okuhlangenwe nakho kukhombisile ukuthi la mapayipi amunca imali ekhishwa yikhabhoni epayipini lokukhipha. Sebenzisa i-screwdriver ephaketheni elincane noma okufanayo ukususa noma yikuphi ukugqwala emapayipini futhi inzwa izoqala ukusebenza futhi.

Uma ukuhlola okuvame kakhulu kwehluleka ukuxazulula inkinga, ibhukwana lesevisi liyadingeka ukuqhubeka nokuhlola amasekhethi kagesi. Isixazululo esingcono kakhulu ukuyisa imoto esikhungweni sesevisi esinezinto ezifanele zokuxilonga. Bangakwazi ukuhlonza ngokushesha futhi balungise lolu hlobo lwenkinga.

Izingxoxo ezihlobene ze-DTC

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

Udinga usizo olwengeziwe ngekhodi yakho ye-p044e?

Uma usadinga usizo nge-DTC P044E, 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.
