1641 is Fan Control Relay.
When your coolant get hot, does your fan turn on?
Get some electronic cleaner and clean the grounds, relay. See if code pops back up. If it does, replace the relay and go from there.
1661 is Malfunction Indicator Lamp (MIL) Control Circuit.
Most likely a bad bulb.
The system sends electricity through the circuit, if there's a bad bulb the electricity can't complete the circuit and the code pops up.
Replace and re-scan.
