Please note

In most cases, the check engine light comes on even without a fault or because of a minor fault.
The electronics can be fickle and can detect "failures" without incidence :

  • Poor fuel quality,
  • Fuel tank cap improperly closed,
  • Low oil level,
  • A faulty sensor,
  • Etc...

Sometimes, a simple reset via CarDiag can solve a lot of "electronic problems".
