You are going to hate this as much as I did!
In the manual you will read this ..
Manual for Kidde Nighthawk C02 Detector
On page 13
----------------------------------
Unit Malfunction
In the rare event that your alarm malfunctions,
it will alert you with a short “chirp” and the red
LED will flash once every 30 seconds. The
digital model will display “Err” as shown in
Fig. 6.
Seven years after initial power up, this unit will "chirp" every
30 seconds to indicate that it is time to replace the alarm.
The unit will not detect CO in this condition. Please replace
immediately.

Detecotrs have a limited lifespan of 5-7 years. So sounds like you need new one (It's not worth to buy just a sensor). Take a look on amazon: Amazon com Carbon monoxide detector (watch out on reviews). I hope this was helpful. cheers
