Isignali ephezulu ye-P0044 kusilawuli sesilawuli se-oxygen sensor (HO2S) (ibhange 1, inzwa 3)

Idatha ye-OBD-II DTC

I-HO2S Heater Control Circuit Ephakeme (Ibhange 1 Inzwa 3)

Kusho ukuthini lokhu?

Le Khodi Yezinkinga Zokuxilonga (i-DTC) yikhodi yokudlulisela ejwayelekile, okusho ukuthi isebenza ezimotweni ezifakiwe ze-OBD-II, kufaka phakathi kepha kungagcini kuNissan, Mitsubishi, Mazda, Subaru, Toyota, VW, njll. ziyehluka ngokuya ngohlobo lomkhiqizo / imodeli.

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 imininingwane evela ku-Bank 1, HO3S # 2, ngokuyinhloko ukuqapha ukusebenza kahle kwesiguquli se-catalytic. Ingxenye ebalulekile yale nzwa yinto yokushisa. Njengoba ezimotweni ngaphambi kwe-OBD II, inzwa ye-oxygen kwakuyinzwa yocingo olulodwa, manje sekuyizinzwa ezine-wire ezine: ezimbili zinikezelwe inzwa ye-oxygen kanti ezimbili zinikezelwe entweni yokushisa. Isifudumezi senzwa yomoya-mpilo sinciphisa isikhathi esisithathayo ukufinyelela iluphu evaliwe. I-PCM iqaphe isikhathi sokuvula i-heater. I-PCM ibuye ihlole ngokuqhubekayo amasekethe eheater ngamandla kagesi angajwayelekile noma, kwezinye izimo, njengamanje angajwayelekile.

Isifudumezi senzwa yomoya-mpilo silawulwa ngenye yezindlela ezimbili, kuya ngohlobo lomoto. (1) I-PCM ilawula ngqo i-voltage kwi-heater, ngqo noma ngokusebenzisa i-oxygen sensor (HO2S) edluliswayo, futhi inhlabathi itholakala endaweni evumelana nayo imoto. (2) Kukhona i-volt yebhethri eyi-12 volt (B +) enikezela ngama-volts ayi-12 entweni yokufudumeza noma kunini lapho ukuthungela kuvuliwe, futhi i-heater ilawulwa ngumshayeli ku-PCM olawula uhlangothi olungezansi kwesekethe yeheater. ... Ukuthola ukuthi iyiphi onayo kubalulekile ngoba i-PCM izokwenza i-heater isebenze ngaphansi kwezimo ezahlukahlukene.

Uma i-PCM ithola ugesi ophakeme ngokungajwayelekile kusifunda se-heater, i-P0044 ingahle isethwe. Le khodi isebenza kuphela engxenyeni yesekethe yokushisa ye-oxygen sensor.

izimpawu

Izimpawu zekhodi yenkinga ye-P0044 zingafaka:

• Ukukhanya kwe-MIL (Isibani Sesikhombi Sokungasebenzi Kahle)

Cishe, ngeke zibe khona ezinye izimpawu.

izizathu

Izimbangela ezingaba khona zekhodi ye-P0044 zifaka:

• Inzwa ye-oxygen evuthayo engenaphutha # 3 kulayini 1.
• 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 yesithathu yangemuva kwenjini ku-Bank 1 ne-harness yayo ye-wiring. 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 ibhange 3 # 1 HO2S bese uqinisekisa ukuthi ama-volts angu-12 B + akhona injini icishiwe (noma iphansi, kuya ngohlelo). Qinisekisa ukuthi isekhethi yokulawula i-heater ayisebenzi. Uma kunjalo, susa inzwa ye-O2 bese uyihlola ukuthi ayonakele yini. Uma ukwazi ukufinyelela kuzici zokumelana, ungasebenzisa i-ohmmeter ukuhlola ukumelana kwento yokushisa. Ukumelana okungapheli kubonisa isifunda esivulekile ku-heater. Miselela inzwa ye-oxygen uma kunesidingo.
