Umsebenzi we-valve yokulawula i-oyile yemoto kukulungelelanisa uxinzelelo lwe-oyile kunye nokuthintela uxinzelelo lwe-oyile yepompo yeoli ukuba ibe phezulu kakhulu. Ngexesha lesantya esiphezulu, ukunikezelwa kweoli yepompo yeoli kubonakala kukhulu, kwaye uxinzelelo lweoyile luphezulu kakhulu, ngeli xesha, kuyimfuneko ukungenelela ukulungiswa. Ioli evuthayo iya kubangela ukuba ioli evuthayo ibangele ukuba i-oxygen sensor yesithuthi yonakaliswe ngokukhawuleza; Ukutshisa ioyile kuya kukhokelela ekonyukeni kokusetyenziswa kwepetroli, ukukhupha okugqithisileyo, isantya esingazinzanga sokungenzi nto, ukonyusa iingozi ezifihlakeleyo zemoto, kunye nokunyusa umthwalo wezoqoqosho. Ukutshisa ioyile kuya kukhokelela ekuqokeleleni kwekhabhoni eyongeziweyo kwigumbi lokutshisa i-injini, isantya esibuthathaka, isantya esicothayo, ukungabikho kwamandla kunye nezinye iziphumo ezibi.
