I-P0721 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

I-Output Speed ​​​​Sensor Range/Performance

Isho ukuthini ikhodi yephutha P0721?

Ikhodi yezinkinga i-P0721 iyikhodi yokuxilonga yokudlulisa ye-OBD-II evamile esebenza ezimotweni zezinhlobo ezahlukahlukene ezifana neVW, BMW, Mercedes, Chevrolet, GMC, Allison, Duramax, Dodge, Ram, Ford, Honda, Hyundai, Audi nezinye. . Nakuba okujwayelekile ngokwemvelo, izinyathelo ezithile zokulungisa zingahluka kuye ngokuthi unyaka, ukwakhiwa, imodeli nezinto zokusebenza zemoto. Ikhodi ye-P0721 ihlobene nenzwa yejubane lokuphuma kokudlulisela futhi ukusebenza kwayo kungabangelwa amaphutha ahlukahlukene njenge-P0720, i-P0722 ne-P0723, ekhombisa izinkinga ezithile.

Inhloso yenzwa yesivinini sokudlulisa ukuhlinzeka ngolwazi lwesivinini sokudlulisa ku-PCM (imoduli yokulawula injini). Le datha iyadingeka ukuze kulawulwe ama-shift solenoid futhi kuqashwe inqubo yokushintsha igiya, ingcindezi yokudlulisela, futhi kwezinye izimo, i-speedometer.

Ezimotweni ezinokudluliswa okulawulwa nge-elekthronikhi, inzwa yesivinini esiphumayo (OSS) itholakala ekugcineni kwe-shaft ephumayo. Ikala isivinini sokujikeleza kwe-shaft, okubalulekile ekunqumeni isikhathi sokushintsha kwegiya kanye nokusebenza kwesiguquli se-torque.

Uma i-PCM/ECM inquma ukuthi inzwa ye-OSS ayisebenzi kahle noma uma ingaphandle kobubanzi obujwayelekile, ingabangela ukuthi ikhodi ye-P0721 isethwe. Le khodi ikhombisa izinkinga zokudlulisa ezingaba khona futhi ingabangela ukusebenza okuyiphutha kwesiguquli se-torque, isikhathi sokushintsha, neminye imingcele.

Izizathu ezingenzeka

Izimbangela zekhodi ye-P0721 zifaka:

1. Izinkinga ngezintambo noma ukuxhumana.
2. Inzwa yokushisa koketshezi lokudlulisa inephutha.
3. Inzwa yesivinini se-shaft ye-output inephutha.
4. Inzwa yesivinini enephutha.
5. Inzwa yejubane lokukhiphayo enephutha.
6. Uketshezi lokudlulisela olungcolile noma olungcolile.
7. Isihlungi sokudlulisela esingcolile noma esivalekile.
8. Inzwa yezinga lokushisa epholile engalungile.
9. Umzimba we-valve wokudlulisela onesici.
10. Amaphaseji asebenza ngama-hydraulic anomkhawulo.
11. I-solenoid ye-shift engalungile.
12. Isixhumi esigqwalile noma esilimele.
13. Izintambo ezinephutha noma ezilimele.
14. I-PCM enephutha (imodyuli yokulawula injini).

Lapho ikhodi ye-P0721 ivela, kufanele uhlole ukuxilongwa okuningiliziwe futhi uhlonze imbangela ethile yokungasebenzi kahle ukuze wenze ukulungiswa okudingekayo.

Yiziphi izimpawu zekhodi yephutha? P0721?

Izimpawu zekhodi yenkinga ye-P0721 zifaka:

1. Uwonga uphethiloli ompofu.
2. Isibani senjini yokuhlola sivuliwe.
3. Izinkinga ngokushintshwa kwegiya, okuhlanganisa namashifu angazelelwe.
4. Ukusebenza okungalungile kwe-gearbox.
5. I-Speedometer ayisebenzi.
6. Imodi yenjini evilaphayo.
7. Ukushisa kabi noma ukungabaza kwenjini.

Uma lezi zimpawu zikhona, kunconywa ukuthi uhlole ukukhanya kwenjini yakho bese wenza ukuxilonga ukuze uthole imbangela yekhodi ye-P0721.

Indlela yokuxilonga ikhodi yephutha P0721?

Ukuze uhlole futhi uxazulule ikhodi ye-P0721, landela lezi zinyathelo:

1. Hlola amanye amakhodi okuxilonga ku-ECU.
2. Hlola isimo soketshezi oludluliselayo kanye nokuba khona kwezinhlayiya zensimbi ezingase zithinte inzwa ye-OSS.
3. Bheka isimo sehhanisi lezintambo nezixhumi ukuze kugqwele, umonakalo kanye namasekhethi amafushane.
4. Hlola inzwa yesivinini sokudlulisa ukuze uqinisekise ukuthi ihlangabezana nezicaciso zomkhiqizi.
5. Hlola inzwa yesivinini se-shaft ye-transmission input kanye nenzwa yokushisa yokudlulisa uketshezi.
6. Hlola amarekhodi emoto okokugcina kushintshwa isihlungi noketshezi lokudlulisela.
7. Bheka ngeso lengqondo izintambo, izixhumi nezixhumi ngomonakalo.
8. Hlola uxhumano lokudlulisela ukuphepha nenkululeko yokuhamba.
9. Yenza izinqubo ezengeziwe ngokuya ngezincomo ezithile kanye nokulandelana kokuxazulula inkinga kwemoto yakho.
10. Yenza izivivinyo zokuqhubeka kuzintambo nasekuxhumekeni kuyilapho amandla evaliwe ukuze kubonakale izintambo ezinephutha.

Lezi zinyathelo zizosiza ukukhomba nokuxazulula imbangela yekhodi ye-P0721, kuye ngezimo zakho ezithile kanye nemoto.

Amaphutha okuxilonga

5. Ziba Amabhulethi Ezobuchwepheshe Nezincomo Zomkhiqizi: Ziba ulwazi oluvela kumabhulethi wobuchwepheshe (ama-TSB) kanye nezincomo zomkhiqizi ezingase zibonise izinkinga ezivamile noma ukucaciswa kokulungisa.
6. Ukwehluleka ukwenza izivivinyo ezengeziwe: Ukwehluleka ukwenza izivivinyo ezidingekayo ezinzwa nasezintweni zikagesi, okungase kuphumele ekuxilongweni okungalungile.
7. Ukuhluleka ukwenza ukuhlola okuqhubekayo: Ukwehluleka ukuhlola ukuqhubeka ezintanjeni nasekuxhumekeni kungase kuphumele ekulahlekeni kwamaphutha ezintamboni.
8. Ziba izici zemvelo: Ziba imithelela yezinto zemvelo njengokungcola, umswakama noma ukudlidliza ekusebenzeni kwenzwa.

Lawa maphutha angaholela ekuxilongweni okungalungile kanye nezindleko ezingadingekile zokushintsha izingxenye ezingenasici ngempela.

Ibucayi kangakanani ikhodi yephutha? P0721?

Ikhodi yenkinga engu-P0721 ehlotshaniswa nenzwa yesivinini esiphumayo yokudlulisela ingaba yingozi futhi ingase ibe nomthelela ekusebenzeni okuvamile kwemoto. Nazi izici ezimbalwa ezingagqamisa ubucayi bale khodi:

1. Ukulahleka Komnotho Wamafutha: Njengoba le khodi ihlobene nokusebenza kokudlulisela, ukuba khona kwayo kungaholela ekushintsheni kwamagiya okungalungile kanye nomphumela wokulahlekelwa ukonga kukaphethiloli.
2. Ingozi Yokuhlukaniswa Kokudlulisela: Abakhiqizi balungiselele amasistimu okulawula ukudluliswa ukuze agudluze amagiya ngendlela efanele ngokusekelwe kokokufaka kwenzwa yesivinini esiphumayo. Ukungasebenzi kahle kwale nzwa kungaholela ekushintsheni kwamagiya aqinile noma okungalungile, okungase kuholele ekugugekeni nasekulinyazweni kokudlulisela.
3. Ukonakala Kokuphatha: Abakhiqizi bangasebenzisa idatha evela kunzwa yesivinini esiphumayo ukulungisa injini nokusebenza kokudlulisela ezimeni ezihlukahlukene. Inzwa engalungile ingaphazamisa ukuphathwa kwemoto.
4. I-Limp Mode: Kwezinye izimo, lapho kutholwa ikhodi ye-P0721, isistimu yokulawula yemoto ingase ibeke imoto kumodi exegayo, okuzokhawulela ukusebenza kwayo nesivinini ukuze kuvinjwe umonakalo owengeziwe.

Ngakho-ke, ikhodi P0721 kufanele ibhekwe njengento engathi sína futhi idinga ukunakwa ngokushesha. Ukuze ugweme ezinye izinkinga kanye nokulimala, kunconywa ukuthi uthintane nomakhenikha futhi axilonge futhi alungiswe uma kunesidingo.

Yikuphi ukulungisa okuzosiza ukuqeda ikhodi? P0721?

Kungase kudingeke uhlu olulandelayo lokulungisa ukuze kuxazululwe i-DTC P0721:

1. Hlola i-Output Speed ​​​​Sensor (OSS): Umakhenikha kufanele ahlole isimo kanye nokufaka kahle kwenzwa yesivinini esiphumayo. Uma inzwa inesici, kufanele ishintshwe kufakwe entsha.
2. Ukuhlola i-Input Shaft Speed ​​​​Sensor: Umakhenikha kufanele ahlole isimo nokusebenza kahle kwenzwa yesivinini se-shaft yokufaka. Uma kunephutha, kufanele futhi kushintshwe.
3. Ukuhlola i-Transmission Fluid Temperature Sensor: Inzwa yokushisa yokudlulisa uketshezi ingathinta ukusebenza kwesistimu yokulawula ukudlulisa. Uma inesici, kufanele ishintshwe.
4. Ukuhlola Ukuxhuma Kagesi Nezintambo: Umakhenikha kufanele ahlole konke ukuxhumana kukagesi, izintambo, nezixhumi ezihambisana nezinzwa kanye nesistimu yokulawula ukudlulisa. Uma umonakalo utholakala, ukushintshwa kwezintambo noma ukulungiswa kungase kudingeke.
5. Ukuhlola Izinga Le-Transmission Fluid Nesimo: Izinga noma isimo samanzi okudlulisa okungalungile singathinta ukusebenza kwezinzwa nohlelo lokulawula. Uma kunesidingo, uketshezi kufanele kushintshwe futhi izinga liphakanyiswe ezingeni elidingekayo.
6. Hlola izinhlayiya zensimbi kuketshezi lokudlulisela: Izinhlayiya zensimbi oketshezini zingase zibonise izinkinga ngaphakathi kokudluliselwa. Kulokhu, ukudluliselwa kungase kudinge ukulungiswa noma ukushintshwa.
7. Skena futhi usethe kabusha ikhodi yenkinga: Ngemva kokuqeda umsebenzi wokulungisa, umakhenikha kufanele askene isistimu futhi asethe kabusha ikhodi yenkathazo engu-P0721.

Sicela ukhumbule ukuthi izinyathelo eziqondile kanye nobubanzi bomsebenzi kungahluka kuye ngokwakhiwa, imodeli nokucushwa kwemoto. Kubalulekile ukuthi ube nomakhenikha onesipiliyoni noma isitolo sokulungisa izimoto bese usilungisa ukuze uxazulule le khodi yenkinga.
