Hi Mario....welcome to the Forum

It may be that you will need to manually remove the fault codes but otherwise it could be electrical connectors or wiring that are at fault...worth checking further.

Here are some links that may shine some light on the fault..

Thanks for the information I figure out that the wiring was cut so fix the wiring and the check engine went away once again thanks for the info
