I-lambda probe enephutha ithinta ukuwohloka kokwakheka kwamagesi aphumayo kanye nokusebenza kwemoto, ngakho-ke uhlelo lokuxilonga olusebhodini luhlala luhlola ukusebenza kwalo.
Izinhlelo ze-OBDII kanye ne-EOBD zidinga ukusetshenziswa kwe-lambda probe eyengeziwe etholakala ngemuva kwe-catalyst, esetshenziswa, phakathi kwezinye izinto, ukuhlola ukusebenza kwayo. Njengengxenye yokulawula kwazo zombili izinzwa, isistimu ihlola isikhathi sazo sokuphendula nokuqinisekiswa kukagesi. Amasistimu anesibopho sokushisisa ama-probe nawo ayahlolwa.
Umphumela wenqubo yokuguga ye-lambda probe ingase ibe ushintsho esignali yayo, ezibonakalisa ngokwanda kwesikhathi sokuphendula noma ukushintsha kwezici. Lesi simo sakamuva singancishiswa phakathi kwemikhawulo ethile ngenxa yokuthi uhlelo lokulawula ingxube lungakwazi ukuzivumelanisa nezimo zokulawula ezishintshayo. Ngakolunye uhlangothi, isikhathi eside sokuphendula se-probe esitholiwe sigcinwa njengephutha.
Njengomphumela wokuhlolwa kukagesi kwenzwa, isistimu iyakwazi ukubona amaphutha njengokufushane ukuya kokuphozithivu, okufushane ukuya phansi, noma isekethe evulekile. Ngamunye wabo ubonakaliswa ukungabikho kwesignali, futhi lokhu, kubangela ukusabela okuhambisanayo kwesistimu yokulawula.
Isistimu yokushisa ye-lambda probe ivumela ukuthi isebenze ngokukhipha umoya ophansi kanye namazinga okushisa enjini. Ukushisisa kwe-lambda probe ephambi kwe-catalyst kuyavulwa ngokushesha ngemva kokuba injini iqalisiwe. Ngakolunye uhlangothi, umjikelezo wokushisa we-probe ngemuva kwe-catalyst, ngenxa yokuthi kungenzeka ukuthi umswakama ungene ohlelweni lokukhipha, olungalimaza i-heater, lucushwe kuphela lapho izinga lokushisa le-catalyst lifinyelela inani elithile. Ukusebenza kahle kwesistimu yokushisa ye-probe kuqashelwa isilawuli ngokusekelwe esilinganisweni sokumelana nokushisa.
Noma yikuphi ukungasebenzi kahle kwe-lambda probe okutholwe ngesikhathi sokuhlolwa kwesistimu ye-OBD kugcinwa njengephutha uma izimo ezifanele kuhlangatshezwana nazo futhi kuboniswa yi-MIL, eyaziwa nangokuthi I-Exhaust Indicator Lamp noma "Hlola Injini".
