Why is the check engine light flashing on my Chevy Sonic?
The check engine light flashing on your Chevy Sonic indicates a significant issue that requires immediate attention. It is recommended not to drive the vehicle and schedule a service appointment as soon as possible.
There are several potential reasons why the check engine light may be flashing on your Chevy Sonic. Here are some common causes:
1. Engine Misfire: An engine misfire occurs when one or more cylinders fail to ignite properly. This can lead to a flashing check engine light.
2. Evaporative Emissions Control System Faults: Problems with the evaporative emissions control system, such as issues with the gas cap, vapor canister, or other components, can trigger a flashing check engine light.
3. Catalyst Damaging Misfire: A flashing check engine light can indicate a catalyst damaging misfire, which can potentially damage the catalytic converter and O2 sensors.
4. ECU or PCM Issues: If the vehicle’s ECM (Engine Control Module) or PCM (Powertrain Control Module) is experiencing problems or failures, it may misinterpret sensor data and illuminate the check engine light.
To properly diagnose the issue, it is important to have a qualified mechanic use a suitable scanner compatible with your Chevy Sonic to retrieve the engine fault code. This code will provide information about the specific problem detected by the vehicle’s computer.
Remember, ignoring a flashing check engine light can result in severe engine damage, costly repairs, and safety risks on the road. It is best to have the issue diagnosed and repaired promptly by a qualified mechanic.

Can bad spark plugs cause a flashing check engine light?
