Kana paine dambudziko neketani yenguva, mazhinji acho achange aine precursors, semuenzaniso, injini ichaita ruzha. Pamusoro pezvo, dambudziko rekutadza kweketani yenguva rinogonawo kukanganisa kuwedzera kwemafuta emotokari, kuomerwa kutanga mota, kukurumidza kukurumidza, kunonoka kupindura, uye kuburitsa kwakakomba kwemhepo.

Cheni yenguva inozorwa nemafuta ekuzora. Kana iyo injini yekuzora mafuta isina kuchinjwa kwenguva yakareba kana mhando yemafuta isina kunaka, inozowedzera kupesana pakati peketani yenguva uye sprocket uye kupfupisa hupenyu hwecheni yenguva. Kana abrasion iri yakakomba, cheni yenguva inotadza kushanda zvakanaka kana kukuvadzwa, uye inorebeswa zvishoma nezvishoma, uye yakareba inogona kuita seyasvetuka kubva mumazino, zvichikonzera kutadza kweinjini.

Kana cheni yenguva ikasvetuka magiya, mota inobuda yonzwa kupera simba. Kana zino richisvetuka rakanyanyisa, injini inodedera uye inodedera, izvo zvinogona kukonzera kuoma mukutanga motokari, uye kunyange kukanganisa valve. Kana iwe uchida kutarisa kana cheni yenguva yakatambanudzwa, unogona kushandisa chitubu chiyero chekutarisa kureba kweketani munzvimbo nhatu kana kupfuura. Kana ikapfuura kureba yakashandiswa, inofanira kuchinjwa pakarepo; imwe nzira yehunyanzvi ndeyekuenda kuchitoro che4S kuti uiverenge. Tarisa iyo crankshaft sensor uye camshaft sensor. Kana paine alarm yekunonoka kutenderera, panogona kunge paine njodzi yakavanzika yekurebesa cheni, uye inofanirwa kugadziriswa kana kutsiviwa nekukurumidza.
