Here's what you should do:
* Don't ignore it: Continuing to drive with this message could cause further damage.
* Get a diagnostic scan: The most crucial step is to have the car scanned with an OBD-II scanner (many auto parts stores offer this service for free). This will retrieve diagnostic trouble codes (DTCs), which are specific error codes that will help pinpoint the problem.
* Possible causes (these are just examples, the DTC will narrow it down):
* Sensor issues: A faulty oxygen sensor, mass airflow sensor, crankshaft position sensor, camshaft position sensor, or other engine sensors can trigger this message.
* Electrical problems: Worn wiring, loose connections, or a failing engine control module (ECM) could be the culprit.
* Vacuum leaks: A leak in the intake system can disrupt the engine's performance and trigger this message.
* Faulty actuators: Problems with components like the throttle body or variable valve timing system.
Without the diagnostic trouble codes, any further troubleshooting is pure speculation. Taking it to a mechanic or using a professional-grade scanner will be necessary to accurately diagnose and repair the problem. Attempting DIY repairs without proper knowledge could worsen the situation.
