What does the engine symbol on dashboard of a 94 Chevrolet beretta mean?

The engine symbol on the dashboard of a 1994 Chevrolet Beretta, which is usually shaped like a stylized engine or a check engine light, indicates that the powertrain control module (PCM) has detected a problem within the engine or emissions system. It doesn't pinpoint the exact issue, only that something requires attention. The problem could range from something minor (like a loose gas cap) to something serious (like a failing catalytic converter).

To find out what's wrong, you'll need to:

* Get the diagnostic trouble codes (DTCs): This can be done by using an OBD-II code reader (available at most auto parts stores). The code reader will translate the PCM's error codes into a more understandable description of the problem.

* Consult a repair manual: A repair manual specific to your 1994 Chevrolet Beretta will help you interpret the DTCs and suggest potential solutions.

* Take it to a mechanic: If you're not comfortable diagnosing and repairing the problem yourself, a qualified mechanic can use their diagnostic tools to identify and fix the issue.

Ignoring the engine light can lead to further damage and potentially expensive repairs down the road. It's best to address it promptly.
