Isignali ephezulu ye-P0058 kusilawuli sesilawuli se-oxygen sensor (HO2S) (ibhange 2, inzwa 2)

Idatha ye-OBD-II DTC

Okujwayelekile: I-HO2S I-Heater Control Circuit High (I-Bank 2 Sensor 2) I-Nissan: Inzwa Ye-oksijeni Eshisayo (HO2S) 2 Ibhange 2

Kusho ukuthini lokhu?

Le khodi iyikhodi yokudlulisela ejwayelekile. Kubhekwa njengendawo yonke njengoba kusebenza kukho konke ukwakheka namamodeli ezimoto (1996 nangaphezulu), yize izinyathelo ezithile zokulungisa zingahluka kancane ngokuya ngemodeli.

Izinzwa ze-oxygen ezinesici sokushisa zisetshenziswa kakhulu ezinjini zanamuhla. Izinzwa Zomoya Oshisayo (HO2S) okokufaka okusetshenziswa i-PCM (Powertrain Control Module) ukuze kutholwe inani le-oxygen kusistimu yokukhipha umoya.

I-PCM isebenzisa ulwazi oluthola ebhange le-2,2 HO2S ngokuyinhloko ukuze ihlole ukusebenza kahle kwesiguquli se-catalytic. Ingxenye ebalulekile yale nzwa yisici sokushisa. Nakuba izimoto zangaphambi kwe-OBD II zinenzwa yomoya-mpilo yocingo olulodwa, izinzwa ezine zezintambo manje sezisetshenziswa kakhulu: ezimbili zenzwa yomoya-mpilo kanye nezimbili zesici se-heater. Isifudumezi senzwa ye-oxygen ngokuyisisekelo sinciphisa isikhathi esisithathayo ukuze sifinyelele iluphu evaliwe. I-PCM ilawula i-heater ngesikhathi. I-PCM futhi ihlale iqapha amasekhethi heater ukuze kutholakale amandla kagesi angavamile noma, kwezinye izimo, ngisho namanje okungajwayelekile.

Kuye ngohlobo lwemoto, isifudumezi senzwa ye-oxygen silawulwa ngendlela eyodwa yezindlela ezimbili. (1) I-PCM ilawula ngokuqondile ukunikezwa kwamandla kagesi ku-heater, ngokuqondile noma ngenzwa yomoya-mpilo (HO2S) edluliselwe, futhi umhlabathi unikezwa endaweni evamile yemoto. (2) Kunefuse yebhethri engu-12 volt (B+) enikezela ngamavolthi angu-12 kusici se-heater noma nini lapho ukuthungela kuvuliwe futhi iheater ilawulwa umshayeli oku-PCM olawula uhlangothi oluphansi lwesekhethi yehitha. . Ukuthola ukuthi iyiphi onayo kubalulekile ngoba i-PCM izovula i-heater ngaphansi kwezimo ezihlukahlukene. Uma i-PCM ithola amandla kagesi aphezulu ngokungavamile kwisekhethi yehitha, ingasethwa i-P0058. Le khodi isebenza kuphela kuhhafu wesekhethi yokushisisa inzwa ye-oxygen. I-Bank 2 iwuhlangothi lwenjini olungaqukethe isilinda #1.

izimpawu

Izimpawu zekhodi yenkinga ye-P0058 zingafaka:

• Ukukhanya kwe-MIL (Isibani Sesikhombi Sokungasebenzi Kahle)

Cishe, ngeke zibe khona ezinye izimpawu.

izizathu

Izimbangela ezingaba khona zekhodi ye-P0058 zifaka:

• Umugqa onamaphutha 2,2 HO2S (inzwa ye-oxygen evuthayo)
• Vula ku-Heater Control Circuit (Izinhlelo Ezilawulwayo ze-12V PCM)
• Mfushane kuya ku-B + (voltage yebhethri) kusifunda sokulawula i-heater (amasistimu alawulwa yi-12V PCM)
• I-Open Ground Circuit (Izinhlelo Ezilawulwayo ze-12V PCM)
• Mfushane phansi emjikelezweni wokulawula i-heater (kuzinhlelo ze-PCM ezibekiwe)

Izixazululo ezingenzeka

Okokuqala, hlola ngokubuka i-HO2S (Heated Oxygen Sensor) 2, 2 block kanye ne-wiring harness yayo. Uma kukhona ukulimala kwenzwa noma yimuphi umonakalo ku-wiring, lungisa lapho kudingeka. Hlola izintambo eziveziwe lapho izintambo zingena khona enzwa. Lokhu kuvame ukuholela ekukhathaleni nasezifundeni ezifushane. Qiniseka ukuthi i-wiring idluliselwe kude nepayipi lokukhipha. Lungisa i-wiring noma buyisela inzwa uma kunesidingo.

Uma KULUNGILE, nqamula i-Bank 2,2 HO2S bese uqinisekisa ukuthi ama-volts angu-12 + akhona enjinini lapho injini icishiwe (noma phansi, kuye ngohlelo) lapho kucishwe khona ukhiye. Qinisekisa ukuthi isekhethi yokulawula i-heater ayisebenzi. Uma kunjalo, susa inzwa ye-o2 bese uyihlola umonakalo. Uma ukwazi ukufinyelela kuzici zokumelana, ungasebenzisa i-ohmmeter ukuhlola ukumelana kwento yokushisa. Ukumelana okungapheli kubonisa isifunda esivulekile ku-heater. Miselela inzwa ye-o2 uma kunesidingo.
