2005 Pontiac Bonneville - "check gauges" flashes and the annoying "ding-ding" keeps sounding

replaced the "anti-lock" sensor. Want to stop the buzzer sound

What "anti-lock" sensor did you replace? I'm not sure what you did?

Read the codes. Is there any gauge that is reading out of range?

Check the battery. How old is it? Check the ground connection from the battery to the rear floor. I'd suggest disconnecting the battery for a while and cleaning the metal at the ground connection.

determine the cause by reading the error code using a scan-tool on the OBD port. damage may be accruing if you drive the car with flashing check-engine light. or the cause might be something as simple as an evap system leak charcoal-canister-tube.
