I-P040A Exhaust Gas Recirculation Temperature Sensor Circuit

Idatha ye-OBD-II DTC

Exhaust negesi Recirculation lokushisa Inzwa Circuit

Kusho ukuthini lokhu?

Le yikhodi ejwayelekile yokuhlola inkinga (DTC) futhi isetshenziswa kakhulu ezimotweni ze-OBD-II. Lokhu kungafaka kepha akukhawulelwe kuMazda, VW, Audi, Mercedes Benz, Ford, Dodge, Ram, njll.

Yize kuvamile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngemodeli yonyaka, ukwakheka, imodeli, nokucushwa kokudluliswa.

Ngaphambi kokuqaliswa kahle kwezinhlelo zokukhishwa kwegesi yokukhipha ezimotweni ezimotweni ngawo-1970, izinjini zazisebenzisa uphethiloli ongashiswanga ngenkuthalo futhi zakhipha emoyeni. Lezi zinsuku, ngakolunye uhlangothi, imoto kufanele ibe nezinga elithile lokukhipha ukuze iqhubeke nokukhiqizwa.

Ukusetshenziswa kwezinhlelo zokukhishwa kwegesi okukhiphe kuye kwaholela ekunciphiseni okukhulu kokukhishwa komoya ngokufaka kabusha amagesi amasha wokuqothula avela kumaningi okuphothula kanye / noma ezinye izingxenye zohlelo lokukhipha futhi siziphindaphinda noma sizishise kabusha ukuqinisekisa ukuthi sishisa uphethiloli esiwukhokhela kahle. ngemizamo yabo yenkani. uthole imali!

Umsebenzi wenzwa yokushisa ye-EGR ukuhlinzeka ngezindlela ze-ECM (module yokulawula injini) ukuqapha izinga lokushisa le-EGR kanye / noma ukulungisa ukugeleza ngokufanele nge-valve ye-EGR. Lokhu kwenziwa kalula ngenzwa yokushisa yohlobo lokuphikisa evamile.

Ithuluzi lakho lokuskena le-OBD (On-Board Diagnostic) lingabonisa i-P040A namakhodi ahlobene lapho i-ECM ithola ukungasebenzi kahle kwenzwa yokushisa ye-EGR noma kumasekethe ayo. Njengoba ngishilo ekuqaleni, uhlelo lubandakanya ukukhipha okushisayo, hhayi lokho kuphela, kepha ubhekene nenye yezindawo ezishisa kakhulu emotweni, ngakho-ke qaphela lapho izandla / iminwe yakho ikhona, noma ngabe injini icishiwe isikhathi esifushane . isikhathi.

Ikhodi P040A Isifunda sesensa yokushisa ye-EGR sisethwe yi-ECM lapho kutholwa iphutha elijwayelekile kwinzwa yokushisa ye-EGR isekethe. Thinta incwadi yakho yokulungisa izimoto ukuthola ukuthi iyiphi ingxenye yochungechunge engu- "A" yohlelo lwakho lokusebenza.

Buyini ubunzima bale DTC?

Ubulukhuni lapha buxhomeke kakhulu enkingeni yakho ethize, kepha bengingeke ngikubeke njengobucayi uma unikezwa iqiniso lokuthi lonke uhlelo lwangeniswa ezimotweni njengecebo lokunciphisa ukungcola. Uma kushiwo lokho, ukukhipha ukuvuza “akulungile” emotweni yakho, futhi izinzwa zokushisa ze-EGR azivuzi noma zinamaphutha, ngakho-ke ukugcinwa kukhiye lapha kungekudala!

Isibonelo se-sensor yokukhipha igesi yokukhipha igesi:

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P040A zingafaka:

• I-smog yesifundazwe / yesifundazwe ehlulekile noma ukuhlolwa kokukhishwa
• Umsindo wenjini (ukungqongqoza, ukukhala, ukukhala, njll.)
• Ukukhipha okukhulu
• Iphunga lokukhipha ngokweqile

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi yenjini engu-P040A zingafaka:

• Inzwa yokushisa ye-EGR enamaphutha noma eyonakele.
• Exhaust igesi recirculation lokushisa inzwa gasket iyavuza
• Ipayipi lokuqhuma eliqhekekile noma elivuzayo lapho kufakwa khona inzwa
• Izintambo ezishisiwe zezintambo kanye / noma inzwa
• Izingcingo (ezilimazayo) (isekethe evulekile, mfushane amandla, mfushane phansi, njll.)
• Isixhumi esonakele
• Inkinga ye-ECM (Engine Control Module)
• Ukuxhumana okungalungile

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P040A?

Isinyathelo esiyisisekelo # 1

Into yokuqala engingathanda ukuyenza lapha ukubheka konke esingakubona ngokumane sihlole inzwa nohlelo oluzungezile lwe-EGR, ikakhulukazi sifuna ukuvuza kokukhipha. Futhi hlola inzwa kanye namahhanisi ayo ngenkathi ulapho. Uyakhumbula ukuthi ngathini ngalawo mazinga okushisa aphezulu? Bangalimaza izintambo zepulasitiki nezenjoloba, ngakho-ke zihlole ngokucophelela.

ICEBISO: Umsizi omnyama ungakhombisa ukuvuza kwangaphakathi endlini.

Isinyathelo esiyisisekelo # 2

Izinkinga eziningi ze-EGR engizibonile esikhathini esidlule zidalwe ukwakheka komsizi ku-exhaust, okungadalwa yizizathu eziningi (ukunakekelwa okungalungile, izinga likaphethiloli elingalungile, njll.). Lokhu akukho okuhlukile kuleli cala, ngakho-ke kungasiza ukuhlanza uhlelo lwe-EGR, noma okungenani inzwa yokushisa. Yazi ukuthi izinzwa ezifakwe ezinhlelweni ze-exhaust zingazizwa zicindezelwe lapho zizama ukuqaqa.

Khumbula ukuthi lezi zinzwa zingaphansi kokushintshashintsha okukhulu kwezinga lokushisa, ngakho-ke ukushisa okuncane okusebenzisa ithoshi le-OAC (hhayi elenzelwe umuntu) kungasiza ekunciphiseni inzwa. Ngemuva kokukhipha inzwa, sebenzisa i-carburetor cleaner noma umkhiqizo ofanayo ukuze ugcwalise kahle umusi. Sebenzisa ibhulashi locingo ukususa umule omningi ezindaweni eziqoqiwe. Lapho ufaka inzwa ehlanzekile, qiniseka ukuthi usebenzisa i-anti-seize compound ezintanjeni ukuvimbela ukugcotshwa.

QAPHELA. Into yokugcina ofuna ukuyenza lapha ukuphula inzwa ngaphakathi kwe-manifold/exhaust manifold. Lokhu kungaba iphutha elibizayo, ngakho-ke thatha isikhathi sakho lapho uphula inzwa.

Isinyathelo esiyisisekelo # 3

Qinisekisa ubuqotho benzwa ngokulinganisa amanani wangempela kagesi ngokuqhathaniswa namanani afunwayo womenzi. Yenza lokhu nge-multimeter bese ulandela izinqubo zokuqinisekisa zokuxhumana zomenzi.

Izingxoxo ezihlobene ze-DTC

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

Udinga usizo olwengeziwe ngekhodi le-P040A?

Uma usadinga usizo maqondana ne-DTC P040A, 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.
