Puragi yekunzwa mafuta inoreva sensor yekumanikidzwa kwemafuta. Pfungwa yacho ndeyekuti kana injini ichishanda, mudziyo wekuyera kumanikidzwa unoona kumanikidzwa kwemafuta, woshandura chiratidzo chekumanikidzwa kuita chiratidzo chemagetsi, wochitumira kudunhu rekugadzirisa masaini. Mushure mekuwedzera simba remagetsi uye kuwedzera simba remagetsi, chiratidzo chekumanikidzwa chakawedzerwa chinobatanidzwa negeji yekumanikidza kwemafuta kuburikidza nemutsetse wechiratidzo.
Kumanikidzwa kwemafuta einjini kunoratidzwa nechiyero chemagetsi ari pakati pemakoiri maviri ari muchiratidzo chekumanikidzwa kwemafuta chinoshanduka. Mushure mekuwedzera simba uye kuwedzera simba, chiratidzo chekumanikidzwa chinoenzaniswa nemagetsi ekunyevera akaiswa mudunhu rekunyevera. Kana magetsi ekunyevera akaderera pane magetsi ekunyevera, dunhu rekunyevera rinoburitsa chiratidzo chekunyevera uye rinobatidza rambi rekunyevera kuburikidza nemutsetse wekunyevera.
Chinoongorora kumanikidzwa kwemafuta chinhu chakakosha pakuona kumanikidzwa kwemafuta einjini yemotokari. Kuyerwa kwacho kunobatsira kudzora mashandiro einjini.
Puragi yekunzwa mafuta inoumbwa nechipu ye "pressure sensor chip" yakakora, dunhu rekugadzirisa masaini, housing, mudziyo we "fixed circuit board" uye ma "leads" maviri (mutsara wechiratidzo nemutsara wealamu). Dunhu rekugadzirisa masaini rine dunhu remagetsi, dunhu re "sensor compensation", dunhu re zerosetting, dunhu re "voltage amplifier", dunhu re "current amplifier", dunhu re "filter" nedunhu re "alamu".
