Idatha ye-OBD-II DTC

Ukudla Inzwa Yokushisa Kwomoya 2 Ukungasebenzi Kwesekethe

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) iyikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza kuzo zonke izimoto kusukela ngo-1996 (Ford, Mazda, Mercedes Benz, njll.). Yize kuvamile emvelweni, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Ikhodi egcinwe i-P0099 isho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole okokufaka okuvela ngezikhathi kusuka kusekhethi ye- # 2 intake air temperature (IAT).

I-PCM isebenzisa okokufaka kwe-IAT kanye nokufakwa kwenzwa yesisindo somoya (MAF) ukubala ukulethwa kukaphethiloli nesikhathi sokushisa. Njengoba ukugcina isilinganiso esifanele somoya / sephethiloli (ngokujwayelekile i-14: 1) kubalulekile ekusebenzeni kwezinjini nakumnotho wephethiloli, okokufaka kwe-IAT sensor kubaluleke kakhulu.

Inzwa ye-IAT ingafakwa ngqo esikalini esiningi, kepha kaningi ifakwa ebhokisini lokungenisa eliningi noma elihlanza umoya. Abanye abakhiqizi bafaka inzwa ye-IAT ezindlini zezinzwa ze-MAF. Kunoma ikuphi, kufanele ibekwe kahle ukuze (lapho injini isebenza) umoya omile odonswe kokuphindaphindwayo kokudla emzimbeni we-mpintsha ukwazi ukugeleza ngokuqhubekayo nangokulinganayo ngawo.

Inzwa ye-IAT imvamisa inzwa ye-thermistor enezintambo ezimbili. Ukumelana kwenzwa kuyashintsha kuye ngokuthi izinga lokushisa lomoya elidlula entweni ebandayo yocingo. Iningi lezimoto ezihlomile ze-OBD II zisebenzisa i-voltage voltage (ama-volts amahlanu ajwayelekile) nesiginali yomhlabathi ukuvala isekethe yezinzwa ze-IAT. Amazinga ahlukile wokumelana entweni yokuzwa kwe-IAT abangela ukushintshashintsha kwamandla kumjikelezo wokufaka. Lokhu kushintshashintsha kuhunyushwa yi-PCM njengezinguquko ekushiseni komoya.

Uma i-PCM ithola inani elithile lamasiginali avela ku-IAT # 2 inzwa esikhathini esithile, ikhodi ye-P0099 izogcinwa futhi isibani sesibonisi sokungasebenzi kahle singakhanyisa.

Ubunzima nezimpawu

Isiginali esivela kwinzwa ye-IAT isetshenziswa yi-PCM ukubala isu likaphethiloli, ngakho-ke ikhodi ye-P0099 kufanele ibhekwe njengebucayi.

Izimpawu zekhodi ye-P0099 zingafaka:

• Kanciphise ukusebenza kwephethiloli kancane
• Ukuncipha kokusebenza kwenjini (ikakhulukazi ngesikhathi sokuqala kwamakhaza)
• Ukungabaza noma ukuqhuma ngokungasebenzi noma ngokusheshisa okuncane
• Amanye amakhodi wokulawula angagcinwa

izizathu

Izimbangela ezingaba khona zale khodi yenjini zifaka:

• Isifunda esivulekile noma esifushane se-wiring kanye / noma izixhumi zenzwa ye-IAT No. 2
• Inzwa yokushisa yomoya engenaphutha # 2.
• Inzwa yokugeleza komoya enesici
• Isihlungi somoya esivinjiwe
• Ukwephuka kwepayipi lokungenisa umoya

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.

Lapho ngibhekene nokuxilongwa kwekhodi ye-P0099, ngithanda ukuba neskena esifanelekile sokuxilonga, i-digital volt / ohmmeter (i-DVOM), i-infrared thermometer, kanye nomthombo onokwethenjelwa wolwazi lwemoto (isb. Yonke Idatha DIY) enginayo.

Xhuma isithwebuli kusokhethi yokuxilonga yemoto uphinde ubuyise ama-DTC agciniwe kanye nedatha yozimele efriziwe. Ngivame ukubhala lolu lwazi phansi uma kwenzeka ngiludinga kamuva. Sula amakhodi bese uhlola ukushayela imoto. Uma ikhodi isethwa kabusha ngokushesha, qhubeka nokuxilonga.

Ochwepheshe abaningi abaqeqeshiwe baqala ngokubheka ngokubonakalayo izintambo nezixhumi ezihambisana nenzwa ye-IAT (ungakhohlwa isihlungi somoya nepayipi lokungenisa umoya). Naka kakhulu isixhumi senzwa njengoba kungenzeka ukuthi igqwale ngenxa yokusondela kwayo eduze kwebhethri kanye nedamu lokupholisa.

Uma i-wiring yesistimu, izixhumi nezingxenye zisebenza kahle, xhuma isithwebuli kusixhumi sokuxilonga bese uvula ukusakazwa kwedatha. Ngokunciphisa ukusakazwa kwedatha yakho ukufaka idatha efanelekile kuphela, uzothola impendulo esheshayo. Sebenzisa i-thermometer ye-infrared ukuqinisekisa ukuthi ukufundwa kwe-IAT (kuskena) kukhombisa kahle ukushisa kwangempela komoya.

Uma lokhu kungenjalo, thintana nomthombo wolwazi lwemoto yakho ukuthola izincomo ekuhlolweni kwe-IAT sensor. Sebenzisa i-DVOM ukuhlola inzwa bese uqhathanisa imiphumela yakho nezincazelo zemoto. Miselela inzwa uma ingahlangabezani nezimfuneko.

Uma inzwa iphasa isivivinyo sokumelana, hlola i-voltage reference voltage nomhlabathi. Uma enye ilahlekile, lungisa okuvulekile noma okufushane kusifunda bese uphinde uzame uhlelo. Uma amasiginali wesethenjwa wesistimu namasiginali womhlaba akhona, thola umdwebo wamandla we-IAT sensor kanye nokushisa okuvela emthonjeni wolwazi lwemoto bese usebenzisa i-DVOM ukubheka amandla okukhipha inzwa. Qhathanisa i-voltage ne-voltage kuqhathaniswa nomdwebo wokushisa bese ushintsha inzwa uma imiphumela yangempela ihlukile ekubekezeleni okuphakanyisiwe okuphezulu.

Uma i-voltage yangempela yokufaka ye-IAT ingaphakathi kokucacisiwe, nqamula izixhumi zikagesi kuzo zonke izilawuli ezihambisanayo bese usebenzisa i-DVOM ukuhlola ukumelana nokuqhubeka kuwo wonke amasekethe asohlelweni. Lungisa noma shintsha noma yimaphi amasekethe avulekile noma amafushane bese uzama uhlelo kabusha.

Uma inzwa ye-IAT nayo yonke imijikelezo yohlelo ingaphakathi kokucacisiwe okunconyiwe, sola iphutha le-PCM elonakele noma le-PCM.

Amanothi wokuxilonga angeziwe:

• Isizathu esivame kakhulu sokugcina i-P0099 isixhumi senzwa se- IAT esinqanyuliwe esingu- # 2. Lapho isihlungi somoya sihloliwe noma kufakwa esinye esikhundleni saso, inzwa ye-IAT ivame ukuhlala ikhubazekile. Uma imoto yakho isanda kusetshenzwa futhi kugcinwa ikhodi ye-P0099 ngokungazelelwe, sola ukuthi inzwa ye-IAT imane nje ayixhunyiwe.

Inzwa ehambisanayo ne-IAT Circuit DTCs: P0095, P0096, P0097, P0098, P0110, P0111, P0112, P0113, P0114, P0127
