Normally this warning will not cause any problem in your system, but if you have ABAP+JAVA stack then you can create a new PSE certificate in JAVA using Visual Administrator and Import it into ABAP using STRUSTSSO2 tcode. Check the below link for creating the new certificate in JAVA.
Normally system PSE is created during the installation process and located in the following file in the directory <instance directory>/sec. I think it named something like this SAPSYS.pse.
If you do not have JAVA stack, I guess you can delete the existing certificate which is going to expire and Create or Import PSE options. Please check the below link for details.
