I-MAP/MAF - I-Throttle Position Correlation

Isho ukuthini ikhodi yephutha 0068?

Le Khodi Yezinkinga Yokuhlola (i-DTC) yikhodi yokudlulisela ejwayelekile. Kubhekwa njengendawo yonke njengoba kusebenza kukho konke ukwakheka namamodeli ezimoto (ngo-1996 nangaphezulu), yize izinyathelo ezithile zokulungisa zingahluka kancane ngokuya ngemodeli.

Ikhodi ejwayelekile yephutha P0068 Kusho inkinga ngokulawulwa kwenjini. Kukhona ukungafani phakathi kwezinzwa zekhompyutha phakathi kwenani lomoya ongena kokuphindaphindwayo kokudla.

I-PCM incike kuzinzwa ezintathu ukukhombisa ivolumu yokuhamba komoya ukubala uphethiloli namaqhinga wesikhathi. Lezi zinzwa zifaka inzwa yokugeleza komoya ngobuningi, inzwa yokuma mpintsha, kanye nenzwa eningi yokucindezela (MAP). Kunezinzwa eziningi enjinini, kodwa ezintathu zihambisana nale khodi.

Inzwa yokugeleza komoya enkulu itholakala phakathi kwesicoci somoya kanye nomzimba we-throttle. Umsebenzi wayo ukukhombisa inani lomoya odlula emzimbeni we-throttle. Ukwenza lokhu, ucezu oluncane lwentambo yokumelana nokuqina njengoboya ludonswa nge-inlet yenzwa.

Ikhompyutha isebenzisa i-voltage kule tambo ukuyishisa ize ifike ezingeni lokushisa elinqunywe kusengaphambili. Njengoba ivolumu yomoya inyuka, kudingeka amandla amaningi ukuze kugcinwe izinga lokushisa. Ngakolunye uhlangothi, njengoba ivolumu yomoya incipha, kudingeka amandla amancane. Ikhompyutha ibona le voltage njengesibonakaliso sevolumu yomoya.

Inzwa yokuma mpintsha ihlala ngakolunye uhlangothi lomzimba wempintsha emzimbeni wempintsha. Lapho ivaliwe, i-valve mpintsha ivimbela umoya ukungena enjinini. Umoya odingekayo wokudlikiza udlula i-valve mpintsha usebenzisa isivinini esingenzi lutho.

Izinhlobo eziningi zakamuva zezimoto zisebenzisa i-floorboard throttle position sensor ngenhla kwephedali ye-accelerator. Lapho i-pedal icindezelekile, inzwa enanyathiselwe ku-pedal ithumela amandla ku-motor kagesi, elawula ukuvulwa kwe-valve mpintsha.

Lapho isebenza, inzwa ye-throttle position ayiyona into engaphezu kwe-rheostat. Lapho i-throttle ivaliwe ngokungenzi lutho, inzwa ye-throttle position ibhalisa eduze kakhulu ne-0.5 volts, futhi lapho ivuliwe, njengaphakathi kokusheshisa, i-voltage iphakama cishe ku-5 volts. Ukushintsha kusuka ku-0.5 kuya ku-5 volts kufanele kube bushelelezi kakhulu. Ikhompyutha yenjini ibona lokhu kwanda kwe-voltage njengesignali ebonisa inani lokugeleza komoya nesivinini sokuvula.

I-Manifold Absolute Pressure (MAP) ibamba iqhaza elikabili kulesi simo. Inquma ingcindezi eninginingi, ilungiswe ukuminyana komoya ngenxa yethempelesha, umswakama nokuphakama. Iphinde ixhunywe kokuphindaphindwayo kokungenisa ngepayipi. Lapho i-valve mpintsha ivuleka ngokuzumayo, ingcindezi eningi yehla ngokuzumayo iphinde ikhuphuke futhi njengoba ukugeleza komoya kukhuphuka.

Ikhompiyutha yokuphatha injini idinga zonke lezi zinzwa ezintathu ukunquma ngokunembile izikhathi zokuvula umjovo kanye nesikhathi sesikhathi sokushisa esidingekayo ukugcina isilinganiso sika-14.5 / 1. yenza amasethingi afanele bese usetha i-DTC P0068.

Izimpawu

Ezinye izimpawu zekhodi engu-P0068 umshayeli angase abe nazo zingase zihlanganise ukungenzi kahle kwenjini ngesikhathi sokupaka nokuncipha, ukuphelelwa amandla ngenxa yomoya omningi ongangena ohlelweni, okungase kuthinte isilinganiso somoya/uphethiloli, futhi ngokusobala hlola inkomba yenjini.

Izimpawu eziboniswa yikhodi ye-P0068 zizoya ngesizathu sokugcwala ngokweqile:

• I-Service Engine noma i-Check Engine light izokhanyisa.

Izinyathelo zokuxilonga kanye nezixazululo ezingaba khona

Njengomakhenikha wezimoto, ake siqale ngezinkinga ezivame kakhulu. Uzodinga i-volt/ohmmeter, igeji ye-punch-hole, ithini lokuhlanza i-carburetor, kanye nekani lokuhlanza umoya. Lungisa noma yiziphi izinkinga njengoba uzithola bese udumisa imoto ukuze ubone ukuthi inkinga isilungisiwe - uma kungenjalo, qhubeka nezinqubo.

Uma injini icishiwe, vula i-hood bese uhlola isici sesihlungi somoya.

Bheka iziqeshana ezixekethile noma ukuvuza kulayini kusuka enzwa ye-MAF uye emzimbeni wempintsha.

Hlola yonke imigqa ye-vacuum kokuphindwe kaningi kokuvinjelwa, ukuqhekeka, noma ukuxegisa okungadala ukulahleka komshini.

Nqamula inzwa ngayinye bese uhlola isixhumi ukuthola ukugqwala nezikhonkwane ezikhishiwe noma ezigobile.

Qala injini bese usebenzisa i-carburetor cleaner ukuthola ukuvuza okuphindaphindayo. Ukudutshulwa okufishane kwesihlanza i-carburetor ngaphezulu kokuvuza kuzoshintsha i-rpm yenjini. Gcina ikani ebangeni lengalo ukugcina okufafazayo kuphume emehlweni akho, noma uzofunda isifundo njengokubamba ikati ngomsila. Ngeke ukhohlwe ngokuzayo. Phatha konke ukuxhumana okuningana kokuvuza.

Khulula i-clamp epayipini elixhuma ukugeleza komoya okukhulu emzimbeni we-throttle. Bheka emzimbeni we-throttle ukuze ubone ukuthi umbozwe yini i-coke, into emnyama enamafutha. Uma kunjalo, qinisa ishubhu ebhodleleni lokungenisa umoya phakathi kweshubhu kanye nomzimba we-throttle. Shelelisela ingono emzimbeni we-throttle bese uqala injini. Qala ukufutha kuze kuphele ikani. Isuse bese uxhuma kabusha ipayipi emzimbeni we-throttle.

Hlola inzwa yokugeleza komoya omningi. Susa isixhumi kunzwa. Vula ukuthungela injini icishiwe. Kukhona izintambo ezintathu, amandla angu-12V, indawo yenzwa nesiginali (imvamisa ephuzi). Sebenzisa umthofu obomvu we-voltmeter ukuhlola isixhumi esingu-12 volt. Gcina ucingo olumnyama phansi. Ukuntuleka kwe-voltage - inkinga ngokuthungela noma izintambo. Faka isixhumi bese uhlola ukuma kwenzwa. Kufanele ibe ngaphansi kuka-100 mV. Uma inzwa ihlinzeka ngo-12V futhi ingaphandle kwebanga, buyisela inzwa. Lokhu ukuhlolwa okuyisisekelo. Uma lapho sekuqedwe zonke izivivinyo iphumelela futhi inkinga iqhubeka, ukugeleza komoya okukhulu kungase kube kubi. Kuhlole kukhompuyutha yezithombe njenge-Tech II.

Hlola ukusebenza kwenzwa yokuma kwe-throttle. Qiniseka ukuthi ifakwe kahle futhi namabhawodi aqinile. Lesi isixhumi esinezintambo ezi-5 - okuluhlaza okwesibhakabhaka okumnyama kwesiginali, okumpunga kwereferensi engu-XNUMXV, kanye nomnyama noma osawolintshi kwentambo enegethivu ye-PCM.

– Xhuma intambo ebomvu ye-voltmeter ocingweni lwesignali eluhlaza okwesibhakabhaka kanye nentambo emnyama ye-voltmeter emhlabathini. Vula ukhiye injini icishiwe. Uma inzwa ilungile, lapho i-throttle ivaliwe, kuyoba ngaphansi kwe-volt engu-1. Njengoba i-throttle ivuleka, i-voltage ikhuphuka ngokushelelayo ifinyelele kuma-volts angu-4 ngaphandle kokuyeka noma ama-glitches.

Hlola inzwa ye-MAP. Vula ukhiye bese uhlola intambo yokulawula amandla ngentambo ebomvu ye-voltmeter, kanye neyomnyama enomhlaba. Uma ukhiye uvuliwe futhi injini icishiwe, kufanele ibe phakathi kuka-4.5 no-5 volts. Qala injini. Kufanele ibe phakathi kuka-0.5 no-1.5 volts kuye ngokuphakama kanye nezinga lokushisa. Khulisa isivinini senjini. I-voltage kufanele iphendule ekuvulekeni kwe-throttle ngokuwa nokukhuphuka futhi. Uma kungenjalo, yishintshe.

AMAPHUTHA AVAMILE LAPHO KUHLOLWA IKHODI P0068

Amaphutha avamile ekuxilongeni ikhodi engu-P0068 angase ahlanganise ukushintsha izingxenye zesistimu kaphethiloli wokuthungela, kucatshangwa ukuthi inkinga yomlilo ongalungile, njengoba lokhu kungabangela injini yenze okufanayo. Okunye ukwehluleka ukuhlonza le nkinga kungase kube ukumiselela inzwa eyodwa noma ngaphezulu ngaphandle kokuhlola ukusebenza kwayo ngaphambi kokushintsha. Ngaphambi kokulungisa kubaluleke kakhulu ukuhlola wonke amaphutha.

IYIZINKANI IKHODI P0068?
