Hi Michael,

I am assuming you are referring to an Opel Mokka as we've had lots of people ask about code 89 in that car.

If the code is being caused by a faulty sensor in the catch (which is a common issue), then yes, it will be cleared by replacing the catch with a new one. Please note that is not the only thing that can cause the spanner icon and code 89, however, so don't change the catch unless a mechanic has confirmed that is the issue.
