I pulled a P1641 and P1642 trouble code with my obd2 code reader.

What is your question?

It says FC Relay 1,2,and 3 Control Circuit. Does this mean I need to find 3 control circuit relays and replace them? The other system checks seem to be in the normal range, (well other than the tach on the dash appears to be reading about 300rpm high). The MIL seems to come on now and then, and stay on, until I park the car for a few days. Thanks for your help.
