Inzwa ye-P014F O2 Impendulo Enensayo - Incike Kokucebile (Inzwa Yebhange 2 1)

Idatha ye-OBD-II DTC

Impendulo Enensayo Yenzwa ye-O2 - Ncika Kokucebile (Ibhange 2, Inzwa 1)

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) ikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezihlonyelwe i-OBD-II (GMC, Chevrolet, Ford, Dodge, Chrysler, VW, Toyota, Honda, njll.). Noma kujwayelekile, izinyathelo ezithile zokulungisa zingahluka ngokuya ngohlobo lomkhiqizo / imodeli.

Uma ikhodi ye-P014F igcinwe emotweni ene-OBD-II, kusho ukuthi imodyuli yokulawula amandla we-powertrain (PCM) ithole isikhathi sokuphendula kancane kusuka kokungenayo (okokuqala ngemuva kokukhipha kusuka enjini engenhla kwesiguquli se-catalytic) inzwa ye-oxygen (O2) noma isekethe yezinjini zomugqa wesibili. IBhange 2 likhomba iqembu lenjini lapho isilinda # 1 singekho khona.

Izinzwa ze-O2 / Oxygen zezimoto zakhiwa kusetshenziswa into yokuzwa i-zirconia evikelwe ngendlu yensimbi eyakhiwe ngokukhethekile. Ama-electrode e-Platinum asetshenziselwa ukunamathisela into yokuzwa ezintanjeni ku-O2 wiring harness harness, exhunywe kwi-PCM nge-Controller Network (CAN). Isiginali kagesi inikezwa i-PCM ngokwamaphesenti ezinhlayiya zomoya-mpilo ekuqedeni kwenjini uma kuqhathaniswa nokuqukethwe kwe-oxygen esemoyeni.

Amagesi wokukhipha angena kumanqwaba (ama) e-exhaust kanye ne-downpipe (s), lapho egeleza khona ngenzwa ye-O2 engaphambi kwayo. Amagesi wokukhipha adlula emiphethweni yenzwa ye-O2 (esimweni sensimbi) futhi inzwa, kuyilapho umoya omile udonswa ngemigodi yezintambo lapho ubhajwe khona egumbini elincane maphakathi nenzwa. Umoya omubi obanjiwe (ekamelweni) ushiswa yimimoya yokukhipha, okwenza ion i-oxygen ikhiqize ukucindezeleka (okunamandla).

Ukuphambuka phakathi kokuhlushwa kwama-molecule e-oksijini emoyeni (okufakwe embotsheni emaphakathi yesenzwa se-O2) kanye nokuhlushwa kwama-oksijeni omoya kugesi wokukhipha kubangela ukuthi i-oxygen oxygen ions ngaphakathi kwenzwa ye-O2 igxume ngokushesha okukhulu phakathi kwezingqimba ze-platinum futhi njalo. Ukuguquguquka kwevolthi kwenzeka lapho i-oksijeni ions igxuma phakathi kwezendlalelo ze-platinum electrode. Lezi zinguquko zamandla kagesi zikhonjwa yi-PCM njengezinguquko ekugxileni komoya-mpilo kumagesi okukhipha, okukhombisa ukuthi injini isebenza ngokuncika (uphethiloli omncane kakhulu) noma ocebile (uphethiloli omningi kakhulu). Lapho i-oksijeni eyengeziwe ikhona ekuqothulweni (isimo esinciphile), isignali yamandla kagesi kusuka ku-O2 sensor iphansi futhi iphakeme lapho umoya-mpilo omncane ukhona ku-exhaust (state rich). Le datha isetshenziswa yi-PCM ngokuyinhloko ukubala izindlela zokulethwa kukaphethiloli nezikhathi zokushisa kanye nokuqapha ukusebenza kahle kwesiguquli se-catalytic.

Uma inzwa ye-O2 okukhulunywa ngayo ingakwazi ukusebenza ngokushesha futhi / noma njalo njengokulindelwe isikhathi esinikeziwe nangaphansi kwezimo ezithile ezinqunyiwe, ikhodi ye-P014F izogcinwa futhi isibani sesibonisi sokungasebenzi kahle singavela.

Amanye ama-DTC ahambisana nokuphendula kwe-Slow O2 Sensor afaka:

• Impendulo Enensayo Yenzwa ye-P013A O2 – Ecebile Ngokuncika (Inzwa Yoku-1 Yebhange 2) I-PXNUMXA OXNUMX Inzwa Enensayo Yokuphendula – Ecebile ku-Lean (банк XNUMX, датчик XNUMX)
• Inzwa ye-P013B O2 Impendulo Enensayo - Incike Kokucebile (Inzwa Yebhange 1 2)
• Inzwa ye-P013C O2 Impendulo Enensayo - Icebile Ukuncika (Inzwa Yebhange 2 2)
• Inzwa ye-P013D O2 Impendulo Enensayo - Incike Kokucebile (Inzwa engu-2 yebhange)
• Inzwa ye-P014C O2 Impendulo Enensayo - Icebile Ukuncika (Inzwa Yebhange 1 1)
• Inzwa ye-P014D O2 Impendulo Enensayo - Incike Kokucebile (Inzwa engu-1 yebhange)
• Inzwa ye-P014E O2 Impendulo Enensayo - Icebile Ukuncika (Inzwa Yebhange 2 1)

Ukuqina kwekhodi nezimpawu

Njengoba ikhodi ye-P014F isho ukuthi inzwa ye-O2 ihlale ingasheshi isikhathi eside, kufanele ibekwe njengobucayi.

Izimpawu zale khodi zingafaka:

• Ukunciphisa ukusebenza kwephethiloli
• Ukuntuleka okuvamile kwamandla enjini
• Amanye ama-DTC ahlobene nawo angagcinwa.
• Isibani senjini yensiza sizokhanyisa kungekudala

izizathu

Izizathu ezingaba khona zokusetha le khodi:

• Inzwa (s) enamaphutha
• Izintambo ezishisiwe, eziphukile noma ezinqanyuliwe kanye / noma izixhumi
• Iphutha lokuguqula okusebenzayo
• Injini iyavuza

Izinqubo zokuxilonga nokulungisa

Amanye amathuluzi ayisisekelo engizowadinga ukuze ngihlole ikhodi ye-P014F iyiskena sokuxilonga, i-digital volt/ohmmeter (DVOM), kanye nomthombo othembekile wolwazi lwemoto (All Data DIY).

Ngaphambi kokuzama ukuthola ikhodi engu-P014F, wonke amakhodi we-engine misfire, amakhodi we-sensor sensor, amakhodi we-air pressure amaningi, namakhodi wezinzwa ze-MAF kufanele atholakale futhi alungiswe. Injini engasebenzi kahle izodala ukuthi zonke izinhlobo zamakhodi zigcinwe (futhi kufanele).

Ochwepheshe abangochwepheshe bavame ukuqala ngokubheka ngokuhlola izintambo nezixhumi zohlelo. Sigxila kumahhanisi ahanjiswa eduze kwamapayipi okushisa okushisayo kanye nezinqwaba, kanye nalawo ahanjiswa ngasemaphethelweni abukhali, njengalawo atholakala emabhokisini e-exhaust.

Sesha ama-bulletins ezinsizakalo zobuchwepheshe (TSB) kumthombo wakho wolwazi wemoto. Uma uthola okufana nezimpawu namakhodi avezwe emotweni okukhulunywa ngayo, kuzokusiza kakhulu ekwenzeni ukuxilongwa. Uhlu lwe-TSB luhlanganiswa kusuka ezinkulungwaneni zokulungiswa okuphumelelayo.

Ngemuva kwalokho ngithanda ukuxhuma isithwebuli ethekwini lokuxilonga imoto bese ngithola wonke ama-DTC agciniwe futhi ngifrize idatha yozimele. Lolu lwazi lungasiza uma i-P014F kuvela ukuthi ayizinzile, ngakho-ke bhala phansi ngokuhamba kwesikhathi. Manje sula amakhodi bese ubona ukuthi i-P014F isethwe kabusha.

Uma ikhodi isuliwe, qala injini, ayivumele ifinyelele izinga lokushisa elijwayelekile, bese uyiyeka idle (ngokudluliswa kungathathi hlangothi noma epaki). Sebenzisa ukusakazwa kwedatha yeskena ukuqapha okokufaka kwenzwa ye-O2.

Nciphisa isibonisi sakho sokugeleza kwedatha ukufaka idatha efanele kuphela futhi uzobona impendulo esheshayo nenembe kakhulu. Uma injini isebenza kahle, ukufundwa kwenzwa ephezulu ye-O2 kufanele kuguquke njalo phakathi kwe-1 millivolt (100 volts) kanye ne-9 millivolts (900 volts). Uma ukwehla kwamandla kagesi kuhamba kancane kunokulindelekile, kuzogcinwa i-P014F.

Ungaxhuma ukuhlolwa kwe-DVOM kuholele emhlabathini wensimbi kanye nemikhombandlela yesiginali yokuqapha idatha yesikhathi sangempela se-O2. Ungayisebenzisa futhi ukuvivinya ukumelana kwenzwa ye-O2 okukhulunywa ngayo, kanye nezimpawu zamandla kagesi nezomhlabathi. Ukuvimbela ukulimala kumodyuli yokulawula, nqamula izilawuli ezifanele ngaphambi kokuhlola ukumelana kwesifunda kohlelo ne-DVOM.

Amanothi wokuxilonga angeziwe:

• Ngemuva kokuthi i-PCM ingene kwimodi evaliwe ye-loop, izinzwa ezisezansi ze-O2 akufanele zisebenze njalo njengezinzwa ezisezingeni eliphezulu.
• Izinguquko eziguqukayo (noma ezifakwe kabusha) ezisezingeni eliphansi ezijwayele ukwehluleka okuphindaphindiwe futhi kufanele zigwenywe.

Izingxoxo ezihlobene ze-DTC

• Okwamanje azikho izihloko ezihlobene ezinkundleni zethu. Thumela isihloko esisha esithangamini manje.

Uma usadinga usizo ngekhodi le-P014F, 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.
