Shaja umoya opholile wokushisa womoya wesifunda, ibhange 1

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlonyisiwe ze-OBD-II ezinenzwa yokushisa epholile yomoya (Chevy, Ford, Toyota, Mitsubishi, Audi, VW, njll) ... Ngaphandle kohlobo olujwayelekile, izinyathelo eziqondile zokulungisa zingahluka ngokuya ngokwenziwa / imodeli.

I-turbocharger iyipompo yomoya esetshenziswa ukuphoqa umoya enjinini. Kunezigaba ezimbili ngaphakathi: i-turbine ne-compressor.

I-turbine ixhunywe ku-exhaust manifold lapho iqhutshwa khona amagesi e-exhaust. I-compressor ixhunywe ekungeneni komoya. Zombili zixhunywe nge-shaft, ngakho-ke njengoba i-turbine spin, i-compressor nayo iyazula, ivumela umoya owukhiphayo ukuthi udonselwe enjinini. Umoya opholile uhlinzeka ngeshaja yokudonsa kanzima enjinini kanjalo namandla engeziwe. Ngenxa yalesi sizathu, izinjini eziningi zifakwe i-aftercooler, eyaziwa nangokuthi i-intercooler. Izipholile zomoya ezishaja zingaba ama-air-to-liquid noma ama-air-to-air, kodwa umsebenzi wazo uyafana - ukupholisa umoya owukhiphayo.

I-Charge Air Cooler Temperature Sensor (CACT) isetshenziselwa ukukala izinga lokushisa ngakho-ke ukuminyana komoya kuqhamuka endaweni epholile yomoya. Lolu lwazi luthunyelwa kumoduli wokulawula amandla we-powertrain (PCM) lapho luqhathaniswa nokushisa komoya (kanti kwezinye izikhathi izinga lokushisa kwenjini kanye nezinga lokushisa le-EGR) ukuthola ukusebenza kokushisa okupholile komoya. I-PCM ithumela i-voltage voltage (ngokujwayelekile ama-volts ama-5) ngokusebenzisa i-resistor yangaphakathi. Ngemuva kwalokho ilinganisa amandla wevolthi ukuthola ukuthi izinga lokushisa lomoya opholile opholile lishisa kangakanani.

Qaphela: Kwesinye isikhathi i-CACT iyingxenye yenzwa yokuqinisa umfutho.

I-P007A isethwe lapho i-PCM ithola ukungasebenzi kahle ebhange 1 ishaja yomoya opholile wesekethe lokushisa. Kuzinjini ezinamabhulokhi amaningi, ibhange 1 libhekisa eqenjini lesilinda eliqukethe isilinda # 1.

Ukuqina kwekhodi nezimpawu

Ubukhali balawa makhodi busesilinganisweni.

Izimpawu zekhodi yenjini engu-P007A zingafaka:

• Hlola Injini Yokukhanya
• Ukusebenza kabi kwenjini
• Ukwehla komnotho kaphethiloli
• Imoto ibhajwe kumodi yokuqhuga.
• Ukuvimbela ukuvuselelwa kwesihlungi se-particulate (uma kuhlonyiwe)

izizathu

Izimbangela ezingaba khona zale khodi ye-P007A zifaka:

• Inzwa engaphelele
• Izinkinga zokufaka izintambo
• Isipholisi somoya opholile noma esilinganiselwe
• I-PCM enamaphutha

Izinqubo zokuxilonga nokulungisa

Qala ngokuhlola ngokubonakalayo inzwa yokushisa epholile yomoya kanye nentambo ehambisanayo. Bheka ukuxhumana okuxekethile, izintambo ezilimele, njll. Futhi ubuke ngokubuka opholile womoya opholile kanye namapayipi omoya. Uma kutholakala umonakalo, lungisa lapho kudingeka, sula ikhodi bese ubona ukuthi iyabuya yini.

Bese ubheka ama-bulletins wensizakalo yezobuchwepheshe (ama-TSBs) ngenkinga. Uma kungatholakali lutho, kuzodingeka uqhubekele ekuhlolweni kwesistimu ngezinyathelo.

Okulandelayo inqubo ejwayelekile njengoba ukuhlolwa kwale khodi kwehlukile emotweni kuya emotweni. Ukuze uvivinye ngokunembile isistimu, udinga ukubhekisa kutchartchch flowchart yomkhiqizi.

• Hlola kuqala isifunda: sebenzisa ithuluzi lokuskena ukuqapha ipharamitha yedatha yesisindo sokushisa somoya. Nqamula inzwa ye-CACT; inani lamathuluzi wokuskena kufanele lehle liye kunani eliphansi kakhulu. Bese uxhuma i-jumper ngaphesheya kwamatheminali. Uma ithuluzi lokuskena manje likhombisa ukushisa okuphezulu kakhulu, ukuxhumana kuhle futhi i-ECM iyakwazi ukubona okokufaka. Lokhu kusho ukuthi inkinga ihlobene kakhulu nenzwa hhayi inkinga yesekethe noma ye-PCM.
• Hlola inzwa: Nqamula isixhumi senzwa yokushisa yomoya opholile. Bese ulinganisa ukumelana phakathi kwamatheminali amabili enzwa nge-DMM esethwe kuma-ohms. Qala injini bese uhlola inani le-counter; amanani kufanele anciphe kancane kancane njengoba injini ifudumala (hlola igeji yokushisa kwenjini kudeshibhodi ukuze uqiniseke ukuthi injini isebenza ngokushisa okusebenzayo). Uma izinga lokushisa kwenjini likhuphuka kepha ukumelana ne-CACT kunganciphi, inzwa inephutha futhi kufanele ithathelwe indawo.

Hlola isifunda

• Bheka ohlangothini lwe-voltage yesekethe yesifunda: Ignition ON, sebenzisa i-digital multimeter esethwe kuma-volts ukuhlola i-5V voltage voltage evela ku-PCM kwenye yamatheminali amabili wenzwa yokushisa epholile yomoya opholile. Uma ingekho inkomba yesethenjwa, xhuma imitha esethwe kuma-ohms (ngokucisha ukucisha) phakathi kwesithenjwa sereferensi ku-CACT kanye ne-voltage reference terminal ku-PCM. Uma ukufundwa kwemitha kungaphandle kokubekezelelana (i-OL), kunesekethe evulekile phakathi kwe-PCM nenzwa edinga ukutholakala nokulungiswa. Uma i-counter ifunda inani lezinombolo, kunokuqhubeka.
• Uma konke kuhamba kahle kuze kube manje, uzofuna ukubheka ukuthi ama-volts ama-5 aphuma kwi-PCM endaweni yokugcina amandla e-voltage. Uma kungekho voltage oyireferensi ongu-5V ovela kwi-PCM, kungenzeka ukuthi i-PCM inephutha.
• Hlola uhlangothi oluphansi lwesekhethi: Xhuma isihloli sokumelana (ukudubula IVALIWE) phakathi kwetheminali yaphansi kwinzwa yezinga lokushisa elipholile komoya kanye netheminali yaphansi ku-PCM. Uma ukufundwa kwemitha kuphelelwe ukubekezelelana (OL), kukhona isifunda esivulekile phakathi kwe-PCM kanye nenzwa okudingeka itholakale futhi ilungiswe. Uma isibali sifunda inani lezinombolo, kukhona ukuqhubeka. Okokugcina, qiniseka ukuthi i-PCM isekelwe kahle ngokuxhuma imitha eyodwa kutheminali ephansi ye-PCM kanye nenye endaweni ye-chassis. Nakulokhu futhi, uma imitha ifundeka ngaphandle kobubanzi (OL), kukhona isekethe evulekile phakathi kwe-PCM nomhlabathi odinga ukutholwa futhi ulungiswe.

Izingxoxo ezihlobene ze-DTC
