I-P2122 Throttle Position Sensor D Circuit Input Low

Incazelo yobuchwepheshe amaphutha P2122

Izinga eliphansi lesiginali yokufaka kuchungechunge lwenzwa yokuma kweveluvemvane / iphedali / iswishi "D"

I-P2122 Ikhodi Yenkinga Yokuxilonga (i-DTC) "yenzwa ye-Throttle Position/Shintsha Okokufaka Okuphansi Kwesekethe". Lokhu kungenzeka ngezizathu ezimbalwa futhi kukumakhenikha ukuthi ahlonze imbangela ethile yale khodi eqalwa esimweni sakho.

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.

I-P2122 isho ukuthi ikhompyutha yemoto ithole ukuthi iTPS (iTrottle Position Sensor) ibika amandla aphansi kakhulu. Kwezinye izimoto, lo mkhawulo ophansi ngu-0.17-0.20 volts (V). Uhlamvu "D" lisho isifunda esithile, inzwa, noma indawo yesekethe ethile.

Ngabe wenze ngezifiso ngesikhathi sokufakwa? Uma isiginali ingaphansi kuka-17V, i-PCM isetha le khodi. Lokhu kungaba okuvulekile noma okufushane phansi emjikelezweni wesiginali. Noma kungenzeka ulahlekelwe yisethenjwa se-5V.

Izimpawu ze-P2122

Izimpawu zingafaka:

• Okubi noma okuphansi
• ukunyakaza
• Ukukhula
• Cha / ukusheshisa okuncane
• ezinye izimpawu nazo zingaba khona

izizathu

Yize kunezimbangela ezimbalwa ezingaba khona zokusethwa kwe-P2122 DTC, kungenzeka ukuthi ingxenye eyodwa kwezine inephutha: inzwa ye-throttle position, i-throttle actuator control motor, i-throttle position actuator, noma inzwa ye-pedal position. Uma zozine zalezi zingxenye zisebenza kahle, imbangela ingase ibe izintambo ezilimele, izixhumi, noma ukubeka phansi.

Ikhodi ye-P2122 ingasho ukuthi umcimbi owodwa noma eminingi yenzekile:

• I-TPS ayixhumekile ngokuphephile
• Isifunda se-TPS: sifushane ukuya emhlabathini noma olunye ucingo
• I-TPS enamaphutha
• Ikhompyutha elimele (PCM)

Izixazululo Ezingenzeka ku-P2122

Nazi ezinye zezinyathelo ezinconyiwe zokuxazulula inkinga nokulungisa:

• Bhekisisa kahle i-Throttle Position Sensor (TPS), isixhumi sezintambo nezintambo zamakhefu, njll. Lungisa noma shintsha lapho kudingeka
• Bheka i-voltage ku-TPS (bona imanuwali yensizakalo yemoto yakho ukuthola eminye imininingwane). Uma i-voltage iphansi kakhulu, lokhu kubonisa inkinga. Shintsha uma kunesidingo.
• Uma kwenzeka kufakwa esikhundleni sakamuva, i-TPS ingadinga ukulungiswa. Kwezinye izimoto, imiyalo yokufaka idinga ukuthi i-TPS iqondaniswe kahle noma ilungiswe, bheka imanuwali lakho le-workshop ukuthola imininingwane.
• Uma kungekho zimpawu, inkinga ingahle ibe phakathi, futhi ukusula ikhodi kungayilungisa okwesikhashana. Uma kunjalo, khona-ke kufanele nakanjani uhlole ukuxhunywa kwentambo ukuze uqiniseke ukuthi ayikhuhli kunoma yini, akunasisekelo, njll. Ikhodi ingabuya.

Umakhenikha uyihlonza kanjani ikhodi ye-P2122?

Ukuze uqale ukuhlonza imbangela ye-DTC P2122, qala uhlole ukuthi ikhona yini. Uchwepheshe oqeqeshiwe angenza lokhu ngedivayisi yokuskena ekhethekile eqoqa idatha yokusebenza kwemoto futhi abike noma yikuphi okudidayo ngendlela yamakhodi ezinkinga. I-OBD-II . Uma umakhenikha eskena futhi ikhodi ye-P2122 ifakiwe, ukuhlolwa okwengeziwe kanye/noma ukuhlola kuyadingeka ukuze kwehliswe izigebengu ezingaba khona.

Isinyathelo esilandelayo ngokuvamile ukuhlola okubonakalayo kwazo zonke izintambo nezixhumi; uma izintambo ezilimele noma izixhumi zitholakala, ziyashintshwa. Umakhenikha ube esesula ikhodi yephutha kumemori yekhompyutha futhi asebenzise isithwebuli esikhethekile futhi. Uma ikhodi P2122 ingabhalisi, inkinga cishe iyoxazululwa. Ngakolunye uhlangothi, uma ikhodi ibhalisa futhi, kuzodingeka imizamo eyengeziwe yokuxilonga.

Ngokusebenzisa i-digital volt/ohmmeter, umakhenikha angakwazi ukuhlola ukufundwa kwamandla kagesi inzwa yokuma kwe-throttle , i-throttle actuator control motor, i-throttle position actuator nenzwa yokuma kwe-pedal. Lokhu kuzosiza ekunqumeni ukuthi noma iyiphi yalezi zingxenye inesibopho sevoltheji ephansi etholwe ikhompuyutha esebhodini ukuze kushintshwe izingxenye ezinephutha. Uchwepheshe angaphinda ahlole i-voltage kunethiwekhi yezintambo, phansi, kanye ne-CAN ukuze alungise noma abuyisele noma yiziphi izingxenye ezigugile noma ezilimele.

Uma ukulungiswa sekuqediwe, umakhenikha uzosula i-OBD-II DTC, aphinde askene ukubona okudidayo, futhi ngokunokwenzeka ahlole ukushayela imoto ukuze aqinisekise ukuthi inkinga ixazululwe ngendlela egculisayo.

Amaphutha Avamile Lapho Uhlonza Ikhodi P2122

Ngemuva kokubhalisa ikhodi ye-P2122, omakhenikha kwesinye isikhathi benza amaphutha alandelayo:

• Ukungakwazi ukuxazulula amakhodi anephutha ngendlela avela ngayo lapho kubhaliswa amakhodi amaningi
• Yehlulekile ukubheka ikhodi engu-P2122
• Ayikwazi ukusetha kabusha ikhodi engu-P2122 kukhompyutha yohambo ngemva kokulungiswa

Ibucayi kangakanani ikhodi ye-P2122?

Yize ezinye izimoto zingangeni esimweni sokuthi "ngeke ziqale" ngemuva kokuthi kufakwe i-P2122 DTC, lokhu akusho ukuthi inkinga eyidalile kufanele ishaywe indiva. Ukuthi imbangela eyinhloko yokungena kwekhodi iyingxenye enephutha, intambo exegayo, noma enye into, ukwehluleka ukulungisa inkinga kungaba nomthelela omubi kwezinye izingxenye noma amasistimu. Ngokuhamba kwesikhathi, lokhu kungaholela ezindlekweni eziningi nezinkinga zokulungisa kunokulungisa ngokushesha.

Yiziphi izilungiso ezingalungisa ikhodi P2122?

Ngemuva kokuthi ukungena kwe-P2122 DTC kuthathwa njengokuvumelekile kusetshenziswa ithuluzi lokuskena elizinikele, kungase kudingeke izinyathelo ezilandelayo:

• Ukushintsha noma ukuhambisa intambo yaphansi
• Ukushintsha Izintambo kanye/noma Izixhumi ku-CAN Bus Harness noma i-Throttle Actuator Motor
• Ukushintsha i-Throttle Position Sensor, Throttle Actuator Motor, Throttle Position Actuator noma i-Pedal Position sensor

Amazwana engeziwe okufanele acatshangelwe mayelana nekhodi P2122

Lapho uxilonga ikhodi engu-P2122, inqubo ingathatha amahora ambalwa. Lokhu kungenxa yesidingo esingaba khona sokuhlola okuningana ngedivayisi yokuskena noma imitha kagesi, ukuhlola okwenziwa ngesandla namadrayivu okuhlola. Ngokusebenza ngokucophelela kusukela ekuqaleni, amathuba okuba nezinye izinkinga ezihlobene ancishiswe kakhulu.

Inzwa ye-P2122 Accelerator Pedal Position

Udinga usizo olwengeziwe ngekhodi le-p2122?

Uma usadinga usizo nge-DTC P2122, 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.
