  2. Na-enyocha ihe mmetụta nrụgide iyuzucha: Kwupu ihe mmetụta nrụgide ikuku gas wee lelee maka nkwụnye ego carbon ma ọ bụ mmebi. Hichaa ma ọ bụ dochie ihe mmetụta ọ bụrụ na ọ dị mkpa.
  3. Nyocha waya: Lelee wiwi ahụ anya, chọọ mmebi, corrosion ma ọ bụ waya gbajiri agbaji. Kwupu njikọ ndị ahụ ma hichaa ha ma ọ dị mkpa.
  4. Na-elele sekit ike na mgbama: Iji mita volt-ohm dijitalụ (DVOM), lelee ike 5V na sekit mgbama na-aga na ihe mmetụta. Jide n'aka na voltaji na-emezu nkọwa ndị nrụpụta.
  5. Nyocha ala: Lelee ma ihe mmetụta nrụgide ikuku iyuzucha ala agbaala nke ọma.
  6. Lelee tube na njikọ: Jiri nlezianya lelee tube na-ejikọta turbocharger na ebe a na-eri ihe maka nkwụsị.
  7. Na-ehichapụ njehie: Jiri nyocha OBD-II iji kpochapụ koodu P0470 na ebe nchekwa PCM. Mgbe nke a gasịrị, kwọọ ụgbọ ala wee lelee ma njehie ahụ pụtara ọzọ.
  8. Ndochi ihe mmetụta: Ọ bụrụ na enweghị ike idozi nsogbu ahụ site na ụzọ ndị ọzọ, dochie ihe mmetụta nrụgide ikuku gas.
  9. Nyocha PCM: Ọ bụrụ na usoro niile a dị n'elu akwụsịghị nsogbu ahụ, enwere ike inwe nsogbu na PCM. Agbanyeghị, nhọrọ a kwesịrị ka ewere ya dị ka ihe enyemaka ikpeazụ.

Cheta na nchoputa na nrụzi ga-abụrịrị onye mekaniki ma ọ bụ ebe ọrụ tozuru etozu iji hụ na ihe kpatara ya na mkpebi dị irè nke koodu P0470.
