I-P2123 Throttle Position Sensor / Shintsha ukufaka kwesekethe okuphezulu

I-P2123 Throttle Position Sensor / Shintsha ukufaka kwesekethe okuphezulu

Idatha ye-OBD-II DTC

I-Throttle / Pedal Position Sensor / Shintsha «D» Ukufakwa Okuphezulu Kwesekethe

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlomele i-OBD-II. Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Lapho ngihlangabezane nekhodi egcinwe i-P2123, ngithole ukuthi kusho ukuthi imodyuli yokulawula i-powertrain (PCM) ithole ukufakwa kwamandla kagesi aphezulu kusuka kusifunda se-throttle position sensor (TPS) noma isekethe elithile le-pedal position sensor (PPS). I- «D» isho isekethe elithile, inzwa, noma indawo yesekethe ethile.

Bheka umthombo othembekile wolwazi lwemoto (yonke imininingwane ye-DIY izosebenza) ngemininingwane yemoto okukhulunywa ngayo. Le khodi isetshenziswa kuphela ezimotweni ezinezinhlelo ze-drive-by-wire (DBW).

I-PCM ilawula uhlelo lwe-DBW isebenzisa i-throttle actuator motor, inzwa eyodwa noma ngaphezulu ye-pedal position (kwesinye isikhathi ibizwa ngokuthi i-accelerator pedal position sensors), nezinzwa zesimo sokuphamba eziningi. Izinzwa zine-voltage voltage (imvamisa i-5 V) nomhlabathi. Izinzwa eziningi ze-TPS / PPS zohlobo lwe-potentiometer futhi ziqedela isekethe efanelekile. Ukunwetshwa kwe-asi evundlile esakhiweni se-accelerator noma ku-shaft mpintsha kushukumisa oxhumana nabo bezinzwa. Ukumelana nenzwa kuyashintsha njengoba izikhonkwane zihamba zinqamula i-PCB yenzwa, zidala izinguquko ekumelaneni kwesifunda kanye namandla kagesi wokufaka ku-PCM.

Uma i-voltage yesiginali yokufaka idlula umkhawulo ohleliwe, isikhathi eside futhi ngaphansi kwezimo ezithile, ikhodi P2123 izogcinwa futhi iLamp Indicator Lamp (MIL) ingakhanyisa.

Izimpawu / ubunzima

Lapho le khodi igcinwa, i-PCM imvamisa ingena kumodi yokukhubazeka. Kule modi, ukusheshisa injini kuzokhawulelwa kakhulu (ngaphandle kokuthi kukhutshaziwe). Izimpawu zekhodi engu-P2123 zingafaka:

• I-Stuck throttle (ngaso sonke isikhathi rpm)
• Ukusheshisa okulinganiselwe noma akukho ukusheshisa
• Izitokisi zenjini lapho idling
• Ukuxoshwa ekusheshiseni
• Ukulawulwa kwemikhumbi akusebenzi

izizathu

Izimbangela ezingaba khona zale khodi yenjini zifaka:

• Isifunda esivulekile noma esifushane kuketanga phakathi kwe-TPS, i-PPS ne-PCM
• I-TPS enephutha noma i-PPS
• Izixhumi zikagesi ezonakalisiwe
• Iphutha lokulawula okukude drive motor

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.

Ngingafinyelela isithwebuli sokuxilonga, i-digital volt / ohmmeter (i-DVOM), nomthombo wolwazi lwemoto njenge-All Data (DIY) ukuthola ikhodi ye-P2123.

Ngingathatha isinyathelo sokuqala sokuxilongwa kwami ​​ngokuhlola ngamehlo yonke intambo nezixhumi ezihambisana nohlelo. Ngiphinde ngithande ukubheka umzimba wempintsha ukuthola izimpawu zokwakhiwa kwekhabhoni noma ukonakala. Ukwakhiwa kwekhabhoni okweqile okugcina umzimba uvuleke ekuqaleni kungaholela ekugcineni ikhodi ye-P2123. Hlanza noma yimaphi ama-carbon deposits avela emzimbeni we-throttle ngokuya ngezincomo zomkhiqizi bese ulungisa noma ushintshe izintambo ezingalungile noma izinto njengoba kudingeka, bese uphinde uzame uhlelo lwe-DBW.

Ngemuva kwalokho ngixhuma isithwebuli ethekwini lokuxilonga imoto bese ngithola wonke ama-DTC agciniwe. Ngikubhala phansi uma kwenzeka ngidinga ukuhleleka obekugcinwa kuwo amakhodi. Ngithanda nokugcina noma iyiphi idatha yozimele efriziwe. Lawa manothi angasiza uma i-P2123 kuvela ukuthi iphakathi. Manje sengisula amakhodi futhi ngivivinya ukushayela imoto. Uma ikhodi isuliwe, ngiyaqhubeka nokuxilonga

Ukuqhuma kwamandla nokungahambi kahle phakathi kwe-TPS, i-PPS ne-PCM kungatholakala kusetshenziswa ukusakazwa kwedatha yesithwebuli. Nciphisa ukusakazwa kwedatha yakho ukubonisa idatha efanelekile yempendulo esheshayo. Uma kungekho ukutholakala kanye / noma ukungahambelani okutholakalayo, sebenzisa i-DVOM ukuthola idatha yesikhathi sangempela kusuka kunzwa ngayinye ngawodwana. Ukuthola idatha yesikhathi sangempela usebenzisa i-DVOM, xhuma isivivinyo siholela kumasiginali afanele namasekethe womhlaba bese ubona isibonisi se-DVOM ngenkathi i-DBW isebenza. Nakekela ama-voltage surges lapho uhambisa kancane i-valve mpintsha kusuka ekuvalweni kuya ekuvulekeni ngokuphelele. Amandla kagesi ngokuvamile avela ku-5V mpintsha ovaliwe kuya ku-4.5V mpintsha ovulekile ovulekile. Uma kutholakala ama-surges noma okunye okungajwayelekile, sola ukuthi inzwa ehlolwayo ayisebenzi. I-oscilloscope futhi iyithuluzi elihle lokuqinisekisa ukusebenza kwenzwa.

Amanothi wokuxilonga angeziwe:

• Abanye abakhiqizi badinga umzimba we-throttle, i-throttle actuator motor, nazo zonke izinzwa zesikhundla se-throttle ukuze zishintshwe ndawonye.
