Ka huri te pukoro rere o te hau i te hau ngotea hei tohu hiko ka tukuna atu ki te waeine mana hiko (ECU) hei tohu taketake hei whakatau i te werohanga wahie. E ai ki nga maataapono ine rereke, ka taea te wehewehe ki nga momo e wha: te hurihanga o te miihini rererangi rererangi (Toyota PREVIA teihana waka), Carmen vortex rangi rere pūoko (Toyota Lexus LS400 motokā), whakatapua pūoko rere rangi (VG30E pūkaha mo Nissan Maxima me Volvo B230F engine mo te whare Tianjin Sanfeng pahi TJ6481AQ4) me te pūoko rere rangi kiriata wera. Ko nga mea tuatahi e rua he momo rerenga rōrahi, ko nga mea whakamutunga e rua he momo rere papatipu. I tenei wa, e rua nga momo o nga pukoro rere o te hau: te pukoro rere rangi i whakatapua me te pūoko rere hau kiriata wera.

1. Ko te kore o te taura hiko rorohiko ka kino te mahi o te miihini motuka me te heke iho o te ohanga, no reira me tirotiro tuatahi te taura hiko rorohiko i mua i te whakakapinga o te rorohiko motuka. (Me whakauru te waea hiko ki te waea whenua kia kiia he taura hiko katoa).

2. Mena he teitei ake te tohu ngaohiko o te hiko o te hiko i te uara paerewa, tera pea kua poke te pukoro, a, he maha nga wa ka nui ake te utu o te hau-wahie.

3. Mēnā he iti ake te tohu o te pūoko hāora i te uara paerewa, tērā pea kei te hē te pūoko, ka puta ki te ōwehenga hau-wahie kikokore o te pūkaha.

4, ka tirohia te pūoko hāora me whakamahi i te multimeter mamati, te oscilloscope ranei.

5. Mēnā he hē te whakawera o te pūoko hāora, ka roa pea te wā mahi o te pūkaha me te whakanui ake i te kohi wahie.

6. Ka taea e te pūoko pāmahana hauhautanga pūkaha te tirotiro i tana mahi ki te mita mamati, ki te mita tairitenga ranei.

7. I roto i te ara iahiko ect o etahi rorohiko, ka whakahaeretia he parenga o roto i tetahi pāmahana o te miihini hei huri i te ngaohiko i runga i te puoro. Mena he rereke te ngaohiko i tenei wa i te inenga, ehara i te mea he he te pukoro.

8. Ka taea e te whakamatautau i te pūoko pāmahana hauhautanga pūkaha me te pūoko pāmahana rangi te whakamahi i te tikanga mahi rite tonu, engari ko te mea anake hei tohu he rereke o raatau huringa huringa pāmahana, na reira karekau he tohu ngaohiko rite i te pāmahana kotahi.

9. I te wa e tuwhera ana te pukoro o te pukoro ka tirohia te tohu ngaohiko o te pukoro tuunga tuunga, ka taea te tirotiro i te pumau o te pukoro ma te wiri me te kaha tika. He tino whai hua tenei tikanga mo etahi hapa hononga mariko ara iahiko.

10. He maha nga waea e wha-waea tuunga tuunga kaareti kei roto ko te whakahuri tuunga mangere, e whakamahia ana hei whakarato i te waahanga whakahaere miihini me nga korero ahua mahi o te miihini i te wa e noho mangere ana te katere.
