Slow O2 Sensor Response - Rich to Lean (Bank 1, Sensor 1)

See se bolela eng?

Khoutu ea Mathata a Tlhatlhobo (DTC) ke khoutu ea phetisetso e akaretsang, ho bolelang hore e sebetsa ho likoloi tse nang le thepa ea OBD-II (GMC, Chevrolet, Ford, Dodge, Chrysler, VW, Toyota, Honda, jj.). Leha e le ka tlhaho ka tlhaho, mehato e ikhethileng ea ho lokisa e ka fapana ho latela mofuta / mofuta.

Ha khoutu ea P014C e bolokiloe ka koloing e nang le thepa ea OBD-II, ho bolela hore module ea powertrain control module (PCM) e fumane nako ea ho arabela butle ho tloha ho e kenang (pele kamora ho tsoa ho enjene e nyolohang mochineng oa phetoho ea catalytic) oksijene (O2) kapa potoloho bakeng sa lienjine tsa mola oa pele. Banka 1 e hlalosa sehlopha sa enjene se nang le silindara palo ea pele.

Lisebelisoa tsa likoloi tsa O2 / Oxygen li hahiloe ho sebelisoa sesebelisoa sa kutlo sa zirconia se sirelelitsoeng ke ntlo ea tšepe e etselitsoeng moea o khethehileng. Li-electrode tsa Platinamo li sebelisetsoa ho hokela sensor ho lithapo tse mochining oa wiring oa O2, o hokahantsoeng le PCM ka Controller Network (CAN). Letšoao la motlakase le fuoa PCM ho latela liperesente tsa likaroloana tsa oksijene tse tsoang ka har'a enjene ha li bapisoa le moea o teng moeeng o haufi.

Likhase tsa ho tsoa moeeng li kena ka bongata (s) le lipompong, moo li phallelang senotlolo sa O2 se ka pela sona. Likhase tsa ho tsoa moeeng li feta ka har'a maqhubu a senotlolo sa O2 (ka ntlong ea tšepe) le ka senorong, ha moea o potolohileng o huleloa ka har'a likhoele tsa wiring moo o qabeletsoeng ka phapusing e nyane bohareng ba sensor. Moea o kenelletseng (ka phapusing) o futhumatsoa ke likhase tse tsoang, tse etsang hore li-ion tsa oksijene li hlahise khatello ea maikutlo.

Ho kheloha lipakeng tsa bongata ba limolek'hule tsa oksijene moeeng o haufi (ho huleloa kahare ho senotlolo sa O2) le ho ts'oaroa ha li-ion tsa oksijene ka har'a khase ea moea ho baka hore li-ion tsa oksijene tse futhumetseng kahare ho senotlolo sa O2 li tlole kapele haholo lipakeng tsa likarolo tsa platinamo le kamehla. Lits'ebetsong tsa voltage li etsahala ha li-ion tsa oksijene li phahama lipakeng tsa li-electrode tsa platinamo. Liphetoho tsena tsa motlakase li khetholloa ke PCM e le liphetoho tsa moea oa oksijene likhase tsa ho qeta, tse bontšang hore enjene e na le mafura (mafura a seng makae) kapa mafura (mafura a mangata). Ha oksijene e ngata e le teng mokhatlong (boemo bo omeletseng), lets'oao la motlakase le tsoang ho sensor ea O2 le tlase ebile le phahame ha oksijene e nyane e le teng mokhatlong o ruileng. Lintlha tsena li sebelisoa ke PCM haholo-holo ho bala maano a phepelo ea mafura le mahlaseli a nako le ho lekola katleho ea mofetoleli ea thusang.

Haeba sensor ea O2 eo ho buuoang ka eona e sa khone ho sebetsa kapele le / kapa khafetsa joalo ka ha ho lebelletsoe nako e fanoeng le tlasa maemo a itseng a reriloeng esale pele, ho tla bolokoa khoutu ea P014C mme lebone la sesupo sa ho se sebetse le ka hlaha.
