Hello

I'm using Carly ODB2 scanner and these two popped up and I don't find anything when I Google the codes (perhaps they have the wrong codes?) 

Hope someone knows what these do and the severity of them but the app does say acceptable

Your diagnostic device may be leading you astray. Searching online for the last code gives a different diagnosis. The following is one of many giving the same result.

The same site gives a different result for your other code:=

Several other sites agree with this.

 

Sorry I can't give further advice on the way forward but others on here may be able to using the information in the links.
