I-P0703 - I-Torque Converter/I-Brake Switch B Ukungasebenzi Kwesekethe

Isho ukuthini ikhodi yenkinga P0703?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) iyikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza kuzo zonke izimoto kusukela ngo-1996 (Ford, Honda, Mazda, Mercedes, VW, njll.). Noma kujwayelekile, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Uma uthola ukuthi ikhodi engu-P0703 igcinwe emotweni yakho ye-OBD-II, kusho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole ukungasebenzi kahle kumjikelezo othize wamabhuleki wesiguquli setorque. Le khodi isebenza kuphela ezimotweni ezifakwe i-automatic transmission.

Ukuthunyelwa okuzenzakalelayo (ezimotweni zokukhiqiza ngobuningi) bekulawulwa ngekhompyutha kusukela ngawo-1980. Izimoto eziningi ezifakwe i-OBD-II zilawulwa yisilawuli sokudlulisa esihlanganiswe ne-PCM. Ezinye izimoto zisebenzisa imodyuli yokuma yodwa ye-powertrain yokuxhumana exhumana ne-PCM nabanye abalawuli nge-Controller Area Network (CAN).

Isiguquli se-torque wuhlobo lwe-hydraulic clutch oluxhuma injini ekudluliseni. Lapho imoto ihamba, isiguquli se-torque sivumela i-torque ukuthi idluliselwe ku-shaft yokufaka yokudlulisela. Lapho imoto ifika ime (uma injini isamile), isiguquli setorque sidonsa itorque yenjini sisebenzisa isistimu yokubamba emanzi eyinkimbinkimbi. Lokhu kuvumela injini ukuthi ingenzi lutho ngaphandle kokuma.

Isiguquli se-torque yokukhiya esisetshenziswe ezimotweni ezifakiwe ze-OBD-II sivumela injini ukuthi ikhiye kushaft yokufaka yokudlulisela ngaphansi kwezimo ezithile. Lokhu kuvamise ukwenzeka lapho ukudluliswa sekushintshele egiyeni eliphakeme, imoto ifike ngejubane elithile futhi nejubane le-injini olifunayo lifinyelelwe. Kumodi yokukhiya, i-torque converter clutch (TCC) incishiswa kancane kancane kuze kube yilapho ukudluliswa kusebenza kungathi kuboshwe ngqo enjinini ngesilinganiso esingu-1: 1. Le mikhawulo yokubamba kancane kancane yaziwa njengephesenti lokuguqulela i-torque converter. Lolu hlelo lunikela emnothweni wephethiloli nasekusebenzeni kahle kwezinjini. Ukukhiya isiguquli se-torque kutholakala nge-solenoid ye-elekthronikhi elawula isiqu esilayishwe entwasahlobo noma i-valve yebhola. Lapho i-PCM ibona ukuthi izimo zilungile, i-solenoid yokukhiya iyasebenza futhi i-valve ivumela uketshezi ukudlula isiguquli se-torque (kancane kancane) futhi igeleze ngqo emzimbeni we-valve.

I-torque converter lock-up kumele ikhishwe ngaphambi kokuthi isivinini senjini sehlele ezingeni elithile, futhi njalo ngaphambi kokuba imoto ingasebenzi. Ngaphandle kwalokho, injini izokuma nakanjani. Esinye sezibonakaliso ezithile ezifunwa yi-PCM lapho kuxhunyaniswa indawo yokuguqula i-torque ukucindezela i-pedal brake. Lapho i-pedal brake icindezelekile, i-lever brake ibangela ukuthi oxhumana nabo abaku-brake switch bavale, bavala isekethe elilodwa noma amaningi. Lapho la masekethe esevaliwe, amalambu amabhuleki ayakhanya. Isiginali yesibili ithunyelwa ku-PCM. Lesi siginali sitshela i-PCM ukuthi i-pedal brake icindezelekile futhi i-solenoid yokukhiya i-converter kufanele ihlukaniswe.

Ikhodi ye-P0703 ibhekisa kwesinye salezi masekhethi wokushintsha amabhuleki. Bheka ibhukwana lesevisi yemoto yakho noma yonke imininingwane ngemininingwane ethile kuleso sifunda esithile esihlobene nemoto yakho.

Izimpawu nobukhali

Le khodi kufanele ibhekwe njengephuthumayo ngoba umonakalo omkhulu wokudluliswa kwangaphakathi ungenzeka uma ilokhi ye-TCC ingasebenzi isikhathi eside. Izinhlobo eziningi zenzelwe ngendlela yokuthi i-PCM izokhipha i-TCC lock bese ifaka uhlelo lokulawula ukudluliswa kwimodi yokukhubazeka uma lolu hlobo lwekhodi lugcinwa.

Izimpawu zekhodi ye-P0703 zingafaka:

• Izitokisi zenjini lapho imoto igingqa ime
• Ukukhiya kwe-TCC kungakhutshazwa
• Ukunciphisa ukusebenza kwephethiloli
• Inciphise amandla enjini (ikakhulukazi ngejubane lomgwaqo omkhulu)
• Amaphethini wokushintsha amagiya angaguquki
• Amabhuleki amalambu angasebenzi
• Misa izibani ezingacimi futhi zihlale zikhanya
• Akukho ukuvala isiguquli se-torque
• Ukuma ngesikhathi sokuma kanye negiya ngenxa yokuvala i-torque converter ayikhiphi.
• I-DTC egciniwe
• I-MIL ekhanyisiwe
• Amanye amakhodi ahlotshaniswa nesiguquli se-torque, i-clutch yokuguqula i-torque, noma ukuvala isiguquli se-torque.

Izimbangela zephutha P0703

Le khodi ivamise ukubangelwa ukushintshwa kwesibani sebhuleki esinephutha noma esingalungiswanga kahle noma ifuse evuthelwe kumjikelezo wokukhanya kwamabhuleki. Amasokhethi amabhuleki amabhuleki angasebenzi kahle, amalambu ashile noma amafushani, izintambo/izixhumi ezivelile noma ezigqwalile nakho kungabangela le DTC.

Izizathu ezingaba khona zokusetha le khodi:

• Iphutha ukubopha switch
• Ukulungiswa okungalungile kwebhuleki
• Isifunda esifushane noma isekethe evulekile ku-wiring kanye / noma izixhumi kusifunda se-brake switch esimakwe ngohlamvu B
• I-fuse evuthiwe noma i-fuse eqhume
• Iphutha lokuhlela le-PCM noma le-PCM elingalungile

Izinqubo zokuxilonga nokulungisa

Iphuzu elihle lokuqala ngaso sonke isikhathi ukuhlola ama-bulletins ezinsizakalo zobuchwepheshe (i-TSB) yemoto yakho ethile. Inkinga yakho ingaba inkinga eyaziwa ngesilungisi esikhishwe ngumkhiqizi futhi ingakongela isikhathi nemali ngenkathi uxazulula inkinga.

Finyelela isithwebuli, i-digital volt / ohmmeter nencwajana yokusebenza (noma yonke idatha) yemoto yakho. Uzowadinga la mathuluzi ukuthola ikhodi ye-P0703.

Qala ngokuhlola okubonakalayo kwe-wiring light wiring kanye nokuhlolwa okujwayelekile kwe-wiring ngaphansi kwe-hood. Bheka amafomu okukhanya kwamabhuleki bese ufaka ama-fuse aqhephukile uma kunesidingo.

Xhuma isithwebuli kusixhumi sokuxilonga bese uthola wonke amakhodi agciniwe bese uqandisa idatha yozimele. Bhala lolu lwazi ngoba lungakusiza ukuthi uqhubeke nokuxilonga. Sula amakhodi bese uhlola ukushayela imoto ukubona ukuthi isetha kabusha ngokushesha.

Uma kunjalo: hlola amandla kagesi webhethri kusekhethi wokufaka okhiye amabhuleki usebenzisa i-DVOM. Ezinye izimoto zinemishini yamabhuleki engaphezu kweyodwa ngoba lapho iphedali yamabhuleki icindezelekile, amalambu amabhuleki kumele akhanyise bese kuvalwa i-torque converter lock-up. Bheka ibhukwana lesevisi yemoto yakho ukuthola ukuthi iswitch brake yakho ilungiselelwe kanjani. Uma kunamandla kagesi ebhethri kusifunda sokufaka, cindezela ibhuleki lokunyathela bese uhlola ivolthi yebhethri kusifunda sokukhiphayo. Uma kungekho voltage kwisekethe yokukhipha, sola ukuthi inkinobho yamabhuleki ayilungile noma ayilungisiwe kahle.

Amanothi wokuxilonga angeziwe:

• Bheka ukuthi amafyuziyali esistimu anepedali yebhuleki ecindezelekile. Amafiyuzi abonakala elungile esivivinyweni sokuqala angahluleka lapho isifunda singaphansi komthwalo.
• Imvamisa, ukushintshwa kwamabhuleki okulungiswe ngokungafanele kungacatshangwa ngephutha ukuthi kunephutha.
• Ukuhlolwa okusheshayo kokusebenza kwe-TCC, letha imoto ngejubane lomgwaqo omkhulu (ezingeni lokushisa elijwayelekile), cindezela kancane iphedali yebhuleki bese uyibamba ngenkathi ugcina ijubane. Uma i-RPM inyuka lapho kufakwa ibhuleki, i-TCC isebenza futhi ibhuleki ibhuleka kahle.
• Uma uhlelo lwe-TCC luhlala lungasebenzi, umonakalo omkhulu ekudlulisweni kungenzeka.

Amaphutha Avamile Lapho Uhlonza Ikhodi P0703

Nakuba inkinga nge-switch light yebhuleki ilula, ingahambisana namanye amakhodi angabangela uchwepheshe ukuthi axazulule inkinga ye-torque converter clutch solenoid noma izintambo.

Ibucayi kangakanani ikhodi ye-P0703?

Ikhodi P0703 ingabangela ukuthi amabhuleki amalambu angasebenzi noma ahlale ekhanya ngaso sonke isikhathi, okuyingozi kakhulu. Kungase futhi kubangele ukuthi isiguquli se-torque singavaliwe noma isekethe yokukhiya inganqamuki, okungase kubangele ukuma noma ezinye izinkinga zokushayeleka.

Yiziphi izilungiso ezingalungisa ikhodi P0703?

• Ukulungisa, ukulungisa noma ukushintshwa kweswishi yesibani sebhuleki .

Amazwana engeziwe okufanele acatshangelwe mayelana nekhodi P0703

Njengezinye izifo zokuxilonga, ikhodi ye-P0703 ingakhomba kuphela uchwepheshe endleleni efanele. Ngaphambi kokufaka noma yiziphi izingxenye, kubalulekile ukulandela inqubo yokuxazulula inkinga ukuze uhlonze kahle ikhodi engu-P0703.
