2. Pambuyo pake, chitsulo chokonzekera kapena nati sichimachotsedwa ndi mutu wa "13" ndi 1/4 ratchet (malingana ndi momwe chipangizocho chimapangidwira).
3.  Ngati ntchito idzachitika kuchokera ku chipinda cha injini, tikulimbikitsidwa kuchotsa zomangira panyumba zotsuka mpweya kuti mupeze DD.
4. Ngati Priora ali ndi mavavu 16 ndi zoziziritsira mpweya, ndiye kuti tiyenera kugwira ntchito kuchokera pansi pa dzenje loyendera. Kuti muwongolere ntchito, mutha kulumikiza chubu la crankcase ventilation mwa kumasula choletsacho.
5. Titachotsa sensor, timapanga njira zoyenera kuti tiyang'ane kapena kuyisintha. Musanakhazikitse chipangizo chatsopano, tikulimbikitsidwa kuyeretsa pamwamba pa chipika cha silinda kuti chisaipitsidwe. Assembly ikuchitika motsatira dongosolo la disassembly.
6. Izi zimamaliza ndondomeko yosinthira. Musaiwale kukonza chip ndikukhazikitsanso zolakwika mutasintha sensor.

Sensor yogogoda pa Priore ndi chinthu chofunikira, kulephera kwake komwe kumayambitsa ntchito yolakwika ya injini. Kuphatikiza pa mfundo yakuti chinthu chosalongosoka sichikudziwitsa ECU za kukula kwa kugogoda kwa injini, izi zimabweretsanso kuchepa kwa mphamvu ya injini, kutayika kwa mphamvu ndi kuwonjezeka kwa mafuta. Ndikofunikira kutenga njira yodalirika yochotsera zomwe zimayambitsa kulephera kwa DD, zomwe ndizowona kuchita nokha popanda kuthandizidwa ndi akatswiri.
