Udindo wa sensor yamafuta ndikuwunika kuthamanga kwamafuta a injini yamagalimoto ndikutumiza izi kugawo lowongolera injini. Chigawo choyang'anira injini chimayang'anira magwiridwe antchito a mpope wamafuta molingana ndi mphamvu yamafuta yomwe idalandilidwa, ndikuwonetsetsa kuti injini ikuyenda bwino. Ngati mphamvu ya mafuta ndi yochepa kwambiri, injini yoyang'anira injini idzasintha kagwiritsidwe ntchito ka pampu yamafuta kuti ibwezeretse mphamvu yamafuta pamlingo wabwinobwino. Ngati kuthamanga kwamafuta kuli kwakukulu, gawo lowongolera injini lisintha magwiridwe antchito a pampu yamafuta kuti asatenthedwe kapena kuwonongeka kwa injini.

Sensa yamphamvu yamafuta imatha kuzindikira momwe injini imagwirira ntchito poyesa kuthamanga kwamafuta. Nthawi zambiri imayikidwa mu makina opangira mafuta a injini ndikulumikizidwa ndi mpope wamafuta. Injini ikagwira ntchito, sensor yamafuta imamva kupanikizika kwamafuta ndikuisintha kukhala chizindikiro chamagetsi kuti ipitirire kugawo lowongolera injini. Gawo loyang'anira injini limazindikira ngati kuthamanga kwamafuta kuli koyenera malinga ndi chizindikiro chamagetsi cholandilidwa, ndipo imatenga njira zofananira kuti zisinthe magwiridwe antchito a pampu yamafuta.

Mukayesa sensor yamafuta, zida zowunikira akatswiri zitha kugwiritsidwa ntchito kuti muwone ngati sensor ikugwira ntchito bwino. Chida chodziwikiratu chimatha kuwerengera chizindikiro kuchokera ku sensa kudzera mu mawonekedwe olumikizidwa ku sensa ndi gawo loyang'anira injini ndikuzindikira ngati sensor ikuwona bwino kuthamanga kwamafuta. Ngati pali vuto ndi sensa, chida chodziwira matenda chidzawonetsa nambala yolakwika yofananira kuti ogwira ntchito yosamalira athe kudziwa chomwe chimayambitsa vutoli ndikuchitapo kanthu kuti athetse vutoli.
