If your Dodge check engine light is illuminated, you can continue to drive the vehicle if no problems arise.
1. Monitor Dashboard Warnings
Before driving, check your dashboard warning lights and gauges to make sure there are no warning lights for low oil pressure or engine overheating. If the engine sounds different, it could be a serious problem that needs to be diagnosed right away. Drive carefully and keep an eye on how the car is running.
2. Check Gas Cap
The light will turn off on its own after a few driving cycles because the ECU will continue to check the EVAP system. Check your gas cap to make sure it is on tight; if it is loose or missing, tighten it until you hear it click.
3. Monitor Engine Temperature
Next, keep an eye on the engine temperature; if your check engine light came on due to an engine misfire, the engine may be about to overheat; if the engine is overheating or the oil light is on, pull over and turn it off.
