My 1998 1.8 20v Passat is showing 2 fault codes and not idling at all when cold, idles irregualr when warm.

1st Code: 4074 - Coolant temperature sender G62 implausible signal.

2nd Code: 45f9 - Idling speed switch F-60 does not close/Open circuit.

Whats this all mean?
What is the F-60 switch?

Whats up with my car?
