Iqhaza lezinzwa zokungcwazi kawoyela ukubheka ingcindezi kawoyela yenjini yemoto futhi idlule lolu lwazi kwiyunithi yokulawula injini. Iyunithi yokulawula injini ilawula ukusebenza kwepompo kawoyela ngokuya ngesiginali yokucindezela kawoyela etholakele, ngaleyo ndlela iqinisekise ukusebenza okujwayelekile kwenjini. Uma ingcindezi kawoyela iphansi kakhulu, iyunithi yokulawula injini izolungisa ukusebenza kwepompo kawoyela ukuze ubuyise ingcindezi kawoyela ebangeni elijwayelekile. Uma umfutho kawoyela uphezulu kakhulu, iyunithi yokulawula injini izolungisa ukusebenza kwepompo kawoyela ukuvikela ukushisa ngokweqile noma ukulimala kwenjini.

Inzwa yokungcwazi kawoyela ingathola isimo sokusebenza senjini ngokulinganisa ingcindezi kawoyela. Imvamisa ifakwe ohlelweni lwe-lubrication lwenjini futhi ixhunywe kwipompo kawoyela. Lapho injini isebenza, inzwa yokungcwazi kawoyela izozwa ingcindezi yamafutha bese iyiguqula ibe isibonakaliso sikagesi ukuze idluliselwe kwiyunithi yokulawula injini. Iyunithi yokulawula injini inquma ukuthi ngabe ukucindezela kawoyela kujwayelekile ngokuya ngesiginali kagesi etholakele, futhi kuthatha izindlela ezihambisanayo zokulungisa ukusebenza kwepompo kawoyela.

Lapho uvivinya inzwa yokungcwazi kawoyela, amathuluzi okuxilonga ochwepheshe angasetshenziswa ukubheka ukuthi ngabe inzwa isebenza kahle yini. Ithuluzi lokuxilonga lingafunda isinali kusuka ku-sensor ngokusebenzisa isikhombimsebenzisi esixhumeke ku-sensor kanye neyunithi yokulawula injini futhi uthole ukuthi inzwa ithola kahle ingcindezi kawoyela. Uma kunenkinga nge-sensor, ithuluzi lokuxilonga lizokhombisa ikhodi yephutha ehambisanayo ukuze abasebenzi bezokulondolozwa basheshe banqume imbangela yenkinga futhi bathathe izinyathelo ezifanele zokuyilungisa.
