Check engine is an error. You have to go at a garage to see what is the error code, then correct the problem.

To reset the check engine light on a Chevy Impala, you can disconnect the negative battery cable for about 15 minutes, which clears the vehicle's computer memory. Alternatively, you can use an OBD-II scanner to read and clear the error codes that triggered the light. If the underlying issue has been resolved, the light should turn off. Always ensure that any problems are addressed before resetting the light to avoid potential damage.
Either try disconnecting thebattery for about 10 mins. or have vehicle scanned to determine the problem
Replace your thermostat had same problem it sets a code but no check engine light
First check your brake fluid level and if full you need to have the ABS wheel sensors checked out for a bad one.
