VBA Macro To Clear Cell When Specific Text Is Entered

I currently use the following code to clear certain cells at a time interval of 2 seconds:

Sub CC()
   Sheet1.Range("O9,O11,O13,L10,L12,L14").ClearContents
   Application.OnTime Now + TimeValue("00:00:02"), "CC"
End Sub

However I would like to clear the cell whenever the cell contains a specific word, ie Total. The cell is updated automatically from another source.

Is there an easy way to change this?

Many Thanks For Any Help!
