P0168 Ukushisa kukaphethiloli kuphakeme kakhulu

Idatha ye-OBD-II DTC

Izinga lokushisa kukaphethiloli liphezulu kakhulu

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezifakiwe ze-OBD-II (iDodge, iRam, iFord, i-GMC, i-Chevrolet, i-VW, iToyota, njll.). Noma kujwayelekile, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Ngithole ukuthi lapho imoto ye-OBD II igcina ikhodi engu-P0168, kusho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole isignali yamandla kagesi kusuka kuzweli lokushisa kwamafutha / inzwa yokwakheka kaphethiloli noma isekethe ekhombisa ukushisa okuphezulu kakhulu kukaphethiloli.

Inzwa yokushisa kaphethiloli imvamisa yakhelwe ensaweni yokwakheka kukaphethiloli. Iyithuluzi elincane elisebenza ngekhompyutha (elifana nesihlungi sikaphethiloli) elenzelwe ukuhlinzeka i-PCM ngohlaziyo olunembile lokwakheka kukaphethiloli nokushisa kwamafutha.

I-Fuel edlula kulenzwa eyakhelwe ngaphakathi ihlaziywa ngekhompyutha ukuthola ukuthi ingcolisa i-ethanol, amanzi, nokungaziwa (okungewona uphethiloli). Inzwa yokwakheka kukaphethiloli ayihlaziyi nje kuphela ukwakheka kukaphethiloli, kodwa futhi ilinganisa izinga lokushisa kukaphethiloli futhi inikeze nesiginali kagesi kwi-PCM engakhombisi nje kuphela ukuthi yiziphi izinto ezingcolisayo ezikhona (nezinga lokungcola kukaphethiloli), kodwa futhi nokushisa kukaphethiloli. Izinga lokungcola kukaphethiloli lihlaziywa yiphesenti lokungcola kukaphethiloli; ukwakheka kwesiginesha yamandla kugesi wokwakheka / inzwa yokushisa.

Isiginesha yamandla kagesi ingena kwi-PCM njengezimpawu zamaza wesikwele. Amaphethini wefomu yamagagasi ayahluka ngobuningi ngokuya ngezinga lokungcola kukaphethiloli. Ukusondelana kwemvamisa yamagagasi kuyanda izinga lokungcola kukaphethiloli; lokhu kuyingxenye eqondile yesiginali. Inzwa yokwakheka kukaphethiloli ihlaziya inani le-ethanol elikhona kuphethiloli ngokwehlukana nokunye ukungcola. Ububanzi be-pulse noma ingxenye enezingqimba ye-waveform ikhombisa isiginesha yamandla kagesi eyenziwe ngamazinga okushisa kaphethiloli. Ukuphakama kwamazinga okushisa kukaphethiloli odlula ngenzwa yokushisa kukaphethiloli; ngokushesha ububanzi be-pulse. Imodemu ejwayelekile yokushintshashintsha kobubanzi be-pulse isukela kumilliseconds owodwa kuye kwayisihlanu, noma ama-hundredths womzuzwana.

Uma i-PCM ithola okokufaka kusuka kunzwa yokushisa / yokwakheka kwephethiloli ekhombisa ukuthi izinga lokushisa likaphethiloli liphezulu kakhulu, kuzogcinwa ikhodi engu-P0168 futhi isibani sesikhombisi esingasebenzi kahle (MIL) singakhanyisa. Kwamanye amamodeli, imijikelezo eminingana yokushisa (ngokungasebenzi kahle) kungadingeka ukuvula isibani sesixwayiso sesibani sokuxwayisa.

Ukuqina kwekhodi nezimpawu

Ikhodi engu-P0168 egciniwe kufanele ibhekwe njengalenzima ngoba izinga lokushisa kukaphethiloli lisetshenziswa yi-PCM ukubala isu lokulethwa kukaphethiloli wezimoto eziguquguqukayo.

Izimpawu zale khodi zingafaka:

• Imvamisa, ikhodi ye-P0168 ayiqondakali.
• Amanye amakhodi wokubumba kaphethiloli angaba khona.
• I-MIL izogcina ikhanya.

izizathu

Izizathu ezingaba khona zokusetha le khodi:

• Ukwakhiwa kukaphethiloli / inzwa yokushisa engaphelele
• Inzwa yezinga lokushisa elibi elibi
• Ukudla inzwa lokushisa lomoya kunephutha
• Vula, isifunda esifushane, noma i-wiring eyonakele noma izixhumi
• Iphutha lokuhlela le-PCM noma le-PCM

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.

Ukuthola ikhodi ye-P0168, uzodinga isithwebuli sokuxilonga, i-digital volt / ohmmeter (i-DVOM), i-oscilloscope, i-infrared thermometer, kanye nomthombo wolwazi lwemoto (njenge-All Data DIY). Kulesi simo, isithwebuli sokuxilonga esine-DVOM esakhelwe ngaphakathi kanye ne-oscilloscope ephathekayo sizongena kahle.

Ukuze wandise amathuba akho okuxilongwa ngempumelelo, qala ngokuhlola ngokubuka wonke amahhanisi nezintambo ezihambisanayo. Uma kunesidingo, uzodinga ukulungisa noma ukufaka ezinye izinto ezilimele noma ezishisiwe bese uzama uhlelo kabusha.

Izinzwa eziningi zokushisa kukaphethiloli zinikezwa ngereferensi ye-XNUMX B nomhlabathi. Njengenzwa yokumelana eguquguqukayo, inzwa yokushisa kukaphethiloli ivala isekethe bese ikhipha ifomu elifanele le-wave kwi-PCM lapho uphethiloli ugeleza. Usebenzisa i-DVOM, hlola amandla wereferensi nomhlabathi kusixhumi senzwa yokushisa kukaphethiloli. Uma kungekho ireferensi yamandla kagesi, sebenzisa i-DVOM ukuhlola amasekethe afanele kusixhumi se-PCM. Uma kutholakala ireferensi yamandla kusixhumi se-PCM, lungisa amasekethe avulekile lapho kudingeka. Isexwayiso: Nqamula bonke abalawuli abahlobene ngaphambi kokuhlola ukumelana kwesifunda ne-DVOM.

Sola i-PCM enesici (noma iphutha lohlelo) uma kungekho ireferensi yamandla kusixhumi se-PCM. Uma ingekho inzwa yokushisa kwamafutha kaphethiloli, sebenzisa umthombo wemininingwane wemoto yakho bese uthola indawo efanelekile yokuqinisekisa ukuthi inokwethenjelwa.

Sebenzisa i-oscilloscope ukubuka idatha yesikhathi sangempela kumagrafu uma ireferensi nomhlabathi kutholakala kusixhumi senzwa yokushisa kukaphethiloli. Ukuhlolwa kwe-Connect kuholela kumasekethe afanele futhi ubuke isikrini sokubonisa. Linganisa ukushisa kukaphethiloli kwangempela nge-thermometer ye-infrared bese uqhathanisa imiphumela nezinga lokushisa eliboniswe kumashadi e-oscilloscope. Uma ukushisa kukaphethiloli okukhonjiswe kwi-oscilloscope kungahambisani nezinga lokushisa kwe-infrared thermometer, sola ukuthi inzwa yokushisa kukaphethiloli inesici.

Amanothi wokuxilonga angeziwe:

• Sebenzisa i-DVOM ukuhlola ukumelana kwenzwa yokushisa kukaphethiloli ngokuya ngezincomo zomkhiqizi.
• Uma izinga lokushisa langempela likaphethiloli liphakeme kunelamukelekayo, hlola isekhethi elifushane ezintanjeni noma emagesi aqediwe ngendlela engafanele eduze kwethangi likaphethiloli noma kolayini bokuhambisa.

Izingxoxo ezihlobene ze-DTC

• 2002 Dodge Grand Caravan - P01684, P0442, P0455, P0456Amakhodi amaphutha akhombisa ukuvuza ohlelweni lwe-evaporator. Njengesinyathelo sokuqala, ngifake ikepisi legesi, kepha angazi ukuthi ngingawasetha kanjani kabusha amakhodi? Ngabe ukhona umzimba ongangisiza? Ngizojabula…. 
• Ikhodi yango-2009 yeJaguar XF 2.7d engu-P0168Sawubona ngiqhubeka ngithola i-PO168 ye-fuel temperature sensor high voltage code. Ngizamile ukuthola ukuthi inzwa itholakala kuphi enjinini ukuze ngikwazi ukubheka isixhumi futhi ngikwazi ukubuyisela inzwa uma inephutha. Futhi, uma ngisetha kabusha i-DTC, imoto izoshayela amamayela angamakhulu ambalwa ngokujwayelekile, kepha ... 

Udinga usizo olwengeziwe ngekhodi le-p0168?

Uma usadinga usizo nge-DTC P0168, thumela umbuzo kumazwana angezansi kwalesi sihloko.

QAPHELA. Lolu lwazi lunikezwa ngenhloso yokwaziswa kuphela. Akuhloselwe ukuthi isetshenziswe njengesincomo sokulungisa futhi asinacala nganoma yisiphi isenzo osithathayo kunoma iyiphi imoto. Yonke imininingwane ekulesi siza ivikelwe yi-copyright.
