P2721 Pressure Control Solenoid D Control Circuit Ukungasebenzi

P2721 Pressure Control Solenoid D Control Circuit Ukungasebenzi

Idatha ye-OBD-II DTC

D I-Pressure Control Solenoid Control Circuit High

Kusho ukuthini lokhu?

Le yikhodi yenkinga yokuxilonga yokudlulisa ejwayelekile (i-DTC) esebenza ezimotweni ze-OBD-II ezinokudluliswa okuzenzakalelayo. Lokhu kungabandakanya, kepha akukhawulelwe, ezimotweni ezivela kwaFord, GMC, Chevrolet, Honda, BMW, Saturn, Land Rover, Acura, Nissan, Saturn, njll. nokulungiswa.

Ezimweni eziningi, ukuthunyelwa okuzenzakalelayo kuzofaka okungenani ama-solenoid wokulawula ingcindezi amathathu aziwa njenge-solenoids A, B, no-C. Ukudluliselwa okusha kuthanda ukuba namagiya amaningi kanye nama-solenoid amaningi, kukunikeze i-solenoids D, E, F, njll. E. Ama-DTC ahlukahlukene ahlotshaniswa nesekethe yokulawula i-solenoid ka "D" kanti ezinye ezijwayeleke kakhulu zifaka i-P2718, P2719, P2720 ne-P2721. Lapho i-DTC P2721 OBD-II isethiwe, imodyuli yokulawula amandla we-powertrain (PCM) ithole inkinga ngesekethe yokulawula ingcindezi yokudlulisa i-solenoid "D". Isethi ethile yamakhodi isuselwa ekusebenzeni okuthile okutholwe yi-PCM.

Ukudluliswa okuzenzakalelayo kulawulwa ngamabhande nokuxhuma okushintsha amagiya ngokufaka ingcindezi yoketshezi endaweni efanele ngesikhathi esifanele. Amaphayiphu we-solenoid control control control aklanyelwe ukulawula ingcindezi yoketshezi yokusebenza okufanelekile kokudlulisa nokushintsha okubushelelezi. I-PCM ibheka ingcindezi ngaphakathi kwama-solenoids futhi iqondisa uketshezi kumasekethe ahlukahlukene wokubacindezela, alungisa isilinganiso sokudlulisa njengoba kudingeka.

I-P2721 isethwe yi-PCM uma ithola ukuthi isifunda sokulawula ingcindezi solenoid "D" siphezulu ngakho-ke asisebenzi kahle.

Isibonelo sama-solenoids wokudlulisa:

Buyini ubunzima bale DTC?

Ubukhali bale khodi imvamisa buqala ngokulingene, kepha bungadlulela ngokushesha buye ezingeni elibi kakhulu uma bungalungiswa ngesikhathi esifanele. Ezimweni lapho ukudluliswa kushayisana khona negiya, kungadala ukulimala kwangaphakathi unomphela, okwenza inkinga ibe nzima.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenkinga ye-P2721 zingafaka:

• Ukwanda kokusetshenziswa kukaphethiloli
• Hlola i-Engine Light On
• Ukushisa kakhulu
• Izitroli zokuhambisa uma ushintsha amagiya
• I-gearbox ishintsha kakhulu (igiya libandakanya)
• Izimpawu ezinjenge-misfire
• I-PCM ibeka ukudluliswa kwimodi yokubhaka.

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi yokudlulisa ye-P2721 zingafaka:

• Iphutha le-solenoid yokulawula ingcindezi
• Uketshezi lokudlulisa olungcolile
• Isihlungi sokuhambisa esilinganiselwe
• Ipompo lokudlulisa elinamaphutha
• Iphutha lokuhambisa umzimba we-valve
• Amaphaseji we-hydraulic avinjiwe
• Isixhumi esonakalisiwe noma esonakele
• Izintambo ezingalungile noma ezilimele
• I-PCM enamaphutha

Yiziphi ezinye zezinyathelo zokuxazulula inkinga nge-P2721?

Ngaphambi kokuqala inqubo yokuxazulula inkinga nganoma iyiphi inkinga, kufanele ubuyekeze i-Technical Service Bulletins (TSB) eqondene nemoto ngonyaka, imodeli nokudluliswa. Kwezinye izimo, lokhu kungakongela isikhathi esiningi ngokuhamba kwesikhathi ngokukukhomba endaweni efanele.

Ukuhlola uketshezi nezintambo

Isinyathelo sokuqala ukuhlola izinga loketshezi futhi uhlole isimo soketshezi ukuthi alinawo yini ukungcola. Ngaphambi kokushintsha uketshezi, kufanele (uma kungenzeka) uhlole amarekhodi emoto ukubheka ukuthi isihlungi noketshezi kugcine nini ukushintshwa.

Lokhu kulandelwa ukuhlolwa okubukwayo okuningiliziwe ukuhlola isimo se-wiring ukuthi sinamaphutha asobala yini. Hlola izixhumi nokuxhuma ukuphepha, ukugqwala nokonakala kwezikhonkwane. Lokhu kufanele kufaka yonke intambo nezixhumi kuma-solenoids wokulawula ingcindezi yokudlulisa, iphampu yokudlulisa, ne-PCM. Ngokuya ngocwaningo oluthile, ipompo yokudlulisa ingaqhutshwa ngogesi noma ngemishini.

Izinyathelo ezithuthukile

Izinyathelo ezingezekile zihlala ziqondene nezimoto futhi zidinga ukuthi imishini efanele ethuthukile yenziwe ngokufanele. Lezi zinqubo zidinga imultimeter yedijithali kanye nemibhalo eqondene nezobuchwepheshe eqondene nemoto. Kufanele njalo uthole idatha ethile yokuxazulula inkinga yemoto yakho ngaphambi kokuqhubeka ngezinyathelo ezithuthukile. Izidingo zamandla kagesi zixhomeke kwimodeli ethile yemoto. Izidingo zokucindezela uketshezi nazo zingahluka ngokuya ngokwakhiwa nokulungiswa kokudluliswa.

Ukuhlolwa kokuqhubeka

Ngaphandle kokuthi kuchazwe ngenye indlela kudathasethi, ukufundwa kwentambo okujwayelekile nokufundwa kokuxhumeka kufanele kube ngama-0 ohms wokumelana. Ukuhlolwa kokuqhubeka kufanele njalo kwenziwe ngamandla wesifunda kunganqanyuliwe ukugwema ukujikeleza okufishane kwesekethe futhi kudale umonakalo omkhulu. Ukumelana noma ukungabikho okuqhubekayo kubonisa izintambo ezingalungile ezivulekile noma ezifushane futhi ezidinga ukulungiswa noma ukushintshwa.

Yiziphi izindlela ezijwayelekile zokulungisa le khodi?

• Kumiselela uketshezi nesihlungi
• Faka esikhundleni se-solenoid yokulawula ingcindezi enesici.
• Lungisa noma shintsha ipompo lokuhambisa elingalungile
• Lungisa noma shintsha umzimba we-valve wokuhambisa onamaphutha
• Ukudluliswa kwe-Flush ukusula izindinyana 
• Ukuhlanza izixhumi kusuka ku-corrosion
• Lungisa noma buyisela izintambo ezingalungile
• Khanyisa noma shintsha i-PCM enesici

Okungahle kwenzeke ku-misdiagnosis kungafaka:

• Inkinga yokusebenza kabi kwezinjini
• Ukungasebenzi kahle kwepompo yokuhambisa
• Inkinga yokudlulisa yangaphakathi
• Inkinga yokudlulisa

Sethemba ukuthi ulwazi olukulesi sihloko luzokusiza ukulungisa iP2721 Pressure Control Solenoid “D” Control Circuit Diagnostic Code (s). Lo mbhalo wenzelwe imininingwane yokwaziswa kuphela futhi imininingwane ethile yezobuchwepheshe kanye namabhulethini wensizakalo yemoto yakho azohlala ehamba phambili njalo.
