Ukuhlangana kwe-P009A phakathi kokushisa komoya okudlayo nokushisa kwama-ambient

Idatha ye-OBD-II DTC

Ukuhlobana phakathi kwezinga lokushisa lomoya othathayo kanye nezinga lokushisa lomoya elizungezile

Kusho ukuthini lokhu?

Le khodi ye-Generic Powertrain Diagnostic Trouble (DTC) ivamise ukusetshenziswa ezimotweni eziningi ze-OBD-II. Lokhu kungase kuhlanganise kodwa akukhawulelwe kuMercedes-Benz, Jeep, Mazda, Ford, njll.

Uma unebulb kafushane ngemva kokuseva injini ngekhodi engu-P009A, kusho ukuthi imojuli yokulawula i-powertrain (PCM) ithole ukungafani kumasiginali ahlobene phakathi kwenzwa yezinga lokushisa lomoya ongenisayo (IAT) kanye nenzwa yezinga lokushisa lomoya elizungezile. Kuyadingeka ukuqhathanisa izinga lokushisa le-IAT nomoya okhona ukuze kuqinisekiswe ukuthi azikho izithiyo ezivimba ukugeleza komoya obalulekile enjinini.

Izinzwa ze-IAT ngokuvamile zihlanganisa i-thermistor ephuma endlini yepulasitiki ngesisekelo sezintambo ezimbili. Inzwa ishuthekwa endaweni yokungenisa umoya noma endaweni yokuhlunga umoya. Idizayini yesibili yenzwa ye-IAT ihlanganisa inzwa ngaphakathi kwe-mass air flow (MAF) inzwa yezindlu. Kwesinye isikhathi isixhasi se-IAT sitholakala ngokuhambisana nocingo olunamandla lwe-MAF, futhi kwezinye izimo sitholakala endaweni yokuphumuza kude nokugeleza komoya. Hlola ukucaciswa kwendawo yenzwa ye-IAT yemoto okukhulunywa ngayo ngaphambi kokwenza noma yikuphi ukuqagela.

I-thermistor ivame ukufakwa ukuze umoya wokungenisa ugeleze kuwo. Umzimba wenzwa ngokuvamile uklanyelwe ukufakwa endaweni yokunamathisela nge-grommet yerabha ewugqinsi. Njengoba izinga lokushisa lomoya wokungena likhuphuka, izinga lokumelana ku-IAT resistor liyancipha; okubangela ukuthi i-voltage yesifunda isondele kumkhawulo wereferensi. Lapho umoya ubanda, ukumelana kwenzwa ye-IAT kuyanda. Lokhu kubangela ukuthi i-voltage kusekethe yenzwa ye-IAT yehle. I-PCM ibona lezi zinguquko ku-voltage yesiginali yenzwa ye-IAT njengezinguquko ekushiseni komoya wokungena.

Inzwa yezinga lokushisa lomoya elizungezile yenza ngendlela efanayo nenzwa ye-IAT. Inzwa yezinga lokushisa elizungezile ivamise ukutholakala eduze nendawo ye-grill.

Ikhodi ye-P009A izogcinwa futhi isibani senkomba esingasebenzi kahle (MIL) singakhanyisa uma i-PCM ithola amasignali kagesi avela kunzwa ye-IAT kanye nenzwa yezinga lokushisa elizungezile ehluka ngaphezu kwenani eliphezulu elivunyelwe isikhathi esithile. Ezinye izimoto zingase zidinge ukuhluleka kokukhanyisa okuningi ukuze kukhanye i-MIL.

Buyini ubunzima bale DTC?

Okokufaka kwenzwa ye-IAT kubalulekile ekulethweni kukaphethiloli futhi ikhodi egciniwe ye-P009A kufanele ichazwe njengebucayi.

Yiziphi ezinye zezimpawu zekhodi?

Izimpawu zekhodi yenjini engu-P009A zingafaka:

• Le khodi ingase ingabonisi zimpawu
• Izinkinga zokulawulwa kwezinjini
• Ukwehla kwamandla kaphethiloli

Yiziphi ezinye zezimbangela ezivamile zekhodi?

Izizathu zale khodi yenjini zingafaka:

• Inzwa ye-IAT ishiywe inqanyuliwe ngemva kwesevisi
• Inzwa yokushisa ye-ambient enephutha
• Inzwa ye-IAT engalungile
• Isifunda esivulekile noma esifushane kumasekethe noma izixhumi
• Iphutha lokuhlela le-PCM noma le-PCM elingalungile

Yiziphi ezinye zezinyathelo zokuxazulula inkinga i-P009A?

Ngaphambi kokuhlonza i-P009A, ngidinga ithemometha ye-infrared ene-laser pointer, isithwebuli sokuxilonga, i-digital volt/ohmmeter (DVOM), kanye nomthombo wolwazi wemoto othembekile.

Ikhodi yenzwa ye-IAT egciniwe ingenze ngabheka into yesihlungi somoya. Kufanele ihlanzeke ngokuqhathaniswa futhi ifakwe ngokufanele ecaleni. Ukuhlolwa okubonakalayo kwenzwa ye-IAT kanye nezintambo zenzwa yezinga lokushisa elizungezile nezixhumi kufanele kwenziwe uma isici sesihlungi somoya sibonakala sisebenza kahle.

Ngabe sengixhuma isithwebuli embobeni yokuxilonga imoto ngathola wonke amakhodi agciniwe futhi ngimise idatha yozimele. Ngokuvamile ngithanda ukubhala lolu lwazi phansi. Lokhu kungaba usizo njengoba inqubo yokuxilonga ikhula. Manje ngizosula amakhodi futhi ngivivinye imoto ukuze ngibone ukuthi i-P009A isethwe kabusha yini. Umthombo wami wolwazi lwemoto kufanele uhlanganise imidwebo yezintambo, amaphinikhodi wesixhumi, ukucaciswa kokuhlolwa kwengxenye, nezinhlobo zezixhumi zemoto okukhulunywa ngayo. Lolu lwazi luzobaluleka lapho kuhlolwa amasekhethi nezinzwa ngazinye. Khumbula ukuvala i-PCM (nazo zonke izilawuli ezihambisanayo) ukuze uvimbele ukulimala kusilawuli lapho uhlola amasekhethi esistimu ngayinye ukuthola ukumelana nokuqhubeka ne-DVOM.

Ihlola i-IAT kanye nezinzwa Zezinga Lokushisa Le-Ambient

1. Sebenzisa i-DVOM kanye nomthombo wakho wolwazi lwemoto oluthembekile.
2. Faka i-DVOM kusethingi ye-Ohm
3. Nqamula inzwa ngaphansi kokuhlolwa.
4. Landela Ukucaciswa Kokuhlola Ingxenye

Izinzwa ezingahlangabezani nezidingo zokuhlolwa kufanele zithathwe njengezinephutha.

Hlola i-voltage yereferensi nendawo

1. Hlola isekethe yereferensi ye-IAT ngayinye nezixhumi zenzwa yezinga lokushisa elizungezile usebenzisa umthofu wokuhlola omuhle ovela ku-DVOM.
2. Hlola itheminali yaphansi ngomthofu wokuhlola onegethivu.
3. Ukhiye uvuliwe futhi injini ivaliwe (KOEO) hlola i-voltage yereferensi (imvamisa engu-5V) futhi igxiliswe kuzixhumi zenzwa ngayinye.

Hlola i-IAT kanye Neziyingi Zesignali Yezinzwa Zezinga Lokushisa E-Ambient

1. Xhuma inzwa
2. Hlola isekethe yesiginali yenzwa ngayinye ngokuhola okuhle kokuhlola okuvela ku-DVOM.
3. Umthofu wokuhlola onegethivu kufanele uxhunywe endaweni eyaziwayo enhle yemoto lapho kuhlolwa isekethe yesignali.
4. Sebenzisa ithemometha ye-infrared ukuze uhlole i-IAT yangempela kanye nezinga lokushisa elizungezile.
5. Buka ukugeleza kwedatha yesithwebuli futhi ubone ukuthi yiziphi i-IAT nezinga lokushisa elizungezile elifakwe ku-PCM noma ...
6. Sebenzisa ishadi lokushisa nelamandla (okutholakala emthonjeni wolwazi lwemoto) ukuthola ukuthi inzwa ngayinye isebenza kahle yini.
7. Lokhu kwenziwa ngokuqhathanisa i-voltage yangempela yesekhethi yesignali yenzwa (eboniswa ku-DVOM) ne-voltage oyifunayo.
8. Uma noma yiziphi izinzwa zingabonisi izinga le-voltage elilungile (ngokusekelwe ku-IAT yangempela kanye nezinga lokushisa elizungezile), sola ukuthi lokhu kuyinto embi.

Uma amasekhethi esignali we-IAT kanye nenzwa yezinga lokushisa elizungezile ibonisa inani le-voltage elihambisanayo

1. Hlola isekethe yesignali (yenzwa okukhulunywa ngayo) kusixhumi se-PCM usebenzisa i-DVOM.
2. Uma kukhona isignali yenzwa efanayo kusixhumi senzwa esingekho kusixhumi se-PCM, sola ukuthi kukhona ukujikeleza okuvulekile phakathi kwakho kokubili.

Sebenzisa zonke ezinye izinketho futhi usole ukwehluleka kwe-PCM (noma iphutha lohlelo lwe-PCM) kuphela uma yonke i-IAT nezinzwa zezinga lokushisa elizungezile namasekhethi kungaphakathi kokucacisiwe.

I-Technical Service Bulletins (TSBs), egcina idatha yemoto, izimpawu, namakhodi, kungenzeka kakhulu ikusize ukuxilonga.
