P0254 Fuel metering fuel “A” control circuit high (cam/rotor/injector)

I-P0254 - I-OBD-II Ikhodi Yenkinga Incazelo Yobuchwepheshe

Ikhodi yenkinga u-P0254 ikhombisa ukuthi iphampu yokulinganisa uphethiloli "A" yokulawula isekethe (ikhamera/irotha/injector) iphezulu kakhulu.

Isho ukuthini ikhodi yephutha P0254?

Ikhodi yezinkinga P0254 ikhombisa inkinga ngohlelo lokuphatha uphethiloli ezinjinini zikadizili. Kubonisa umehluko phakathi kwesignali kagesi ethunyelwe kumshini wokulawula uphethiloli we-elekthronikhi kanye nesignali ye-voltage ebuyiselwa emuva isuka kuyunithi yokulinganisa uphethiloli. Uma i-P0254 yenzeka emotweni esebenzisa uphethiloli, inkinga kungenzeka ibangelwa imodyuli yokulawula injini engalungile (PCM).

Izizathu ezingenzeka

Nazi ezinye zezizathu ezingaba khona zekhodi yenkinga ye-P0254:

• Izinkinga nge-electronic fuel control drive: Izinkinga nge-electronic drive ngokwayo, elawula ukunikezwa kukaphethiloli, ingabangela le khodi ukuthi ivele.
• Izinkinga nge-dispenser fuel: Amaphutha eyunithi yokulinganisa uphethiloli, enesibopho sokukhipha uphethiloli ngokunembile, angabangela ukungqubuzana kwamasignali futhi abangele ukuthi ikhodi ye-P0254 ivele.
• I-voltage engalungile noma ukumelana nesekethe kagesi: Izinkinga ngezintambo, izixhumi, noma ukuxhumeka phakathi kwe-electronic control actuator ne-PCM kungabangela ukuphambana kwesignali futhi kubangele ukuthi kuvele leli phutha.
• Izinkinga zesoftware ye-PCM: Kwesinye isikhathi imbangela ingase ihlobane nesofthiwe ye-PCM, okubangela ukuthi amasignali acutshungulwe ngokungalungile futhi kubangele ukuthi i-P0254 ivele.
• Izinkinga ngezinzwa zomfutho kaphethiloli: Ukungasebenzi kahle kwezinzwa zokucindezela kukaphethiloli noma izinzwa zikaphethiloli kungabangela ukungahambisani kwesignali futhi kubangele ukuthi i-P0254 ivele.
• Imingcele yesistimu ayifani: Ukushintsha isistimu yokulawula uphethiloli noma amapharamitha emitha kaphethiloli kungase kubangele ukuthi le khodi yephutha ivele.

Ukuze unqume ngokunembile imbangela, kuyadingeka ukwenza ukuxilongwa okuningiliziwe kwesistimu yokunikezela uphethiloli usebenzisa imishini ekhethekile.

Yiziphi izimpawu zekhodi yephutha? P0254?

Izimpawu ze-DTC P0254 zingabandakanya lokhu okulandelayo:

• Ukulahleka kwamandla enjini: Esinye sezimpawu ezivame kakhulu ukulahlekelwa amandla enjini, ikakhulukazi lapho ijubane elikhulu noma ngenkathi ushayela.
• Ukusebenza kwenjini okungazinzile: Injini ingase isebenze kanzima, okuhlanganisa ukunyakaza, ukwahlulela, noma ukwenza kahle.
• Ubunzima bokuqalisa injini: Uma kunokungahambi kahle ekunikezeni uphethiloli, kungase kube nzima ukuqalisa injini, ikakhulukazi phakathi nokuqalwa kwamakhaza.
• Ukuwohloka komnotho kaphethiloli: Ikhodi engu-P0254 ingase ibangele ukonga kukaphethiloli okungekuhle ngenxa yokuthi isistimu yokulawula uphethiloli ayisebenzi ngendlela efanele.
• Ukukhishwa kwekhabhoni eyengeziwe: Ukushiswa kukaphethiloli okungaphelele ngenxa yokunikezwa okungafanele kungase kuholele ekwandeni kokukhishwa kwezinto eziyingozi kumagesi akhipha umoya.
• Amaphutha avela kudeshibhodi: Kuye ngesistimu yokuphatha injini ethile, isibani esiyisixwayiso esithi “Hlola Injini” noma amanye amalambu angase abonakale abonisa izinkinga ngesistimu kaphethiloli.

Lezi zimpawu zingase zenzeke ngamazinga ahlukahlukene futhi zingancika kumbangela ethile yenkinga. Uma uqaphela lezi zimpawu, kunconywa ukuthi uxhumane nomakhenikha wezimoto oqeqeshiwe ukuze uxilongwe futhi ulungiswe.

Indlela yokuxilonga ikhodi yephutha P0254?

Ukuze uhlole i-DTC P0254, landela lezi zinyathelo:

1. Ihlola ikhodi yephutha: Sebenzisa isithwebuli sokuxilonga se-OBD-II ukuze ufunde ikhodi yephutha ku-ECU yemoto (Iyunithi Yokulawula Kagesi).
