Frequently Asked Questions Regarding Check Engine Light Repair (FAQ)
- Show AnswerIs it safe to drive with my check engine light on? If the light is steady (not flashing), it is generally safe to drive your vehicle to our shop in Des Moines. However, you should not ignore it, as driving for long periods can damage other components. If the light is flashing, pull over immediately and call for a tow to prevent engine failure.
- Show AnswerCan I just go to an auto parts store for a free scan?A free scan only gives you the "code," not the diagnosis. For example, a code might say "Oxygen Sensor Failure," but the real cause could be a vacuum leak or bad wiring. Replacing the sensor won't fix the leak. Smith Automotive performs the full diagnosis to find the root cause.
- Show AnswerHow long does a diagnostic test take?Most diagnostic scans and physical inspections are completed within 60 minutes. Once we find the issue, we will provide a time estimate for the actual repair.
- Show AnswerWill the light go off on its own?In rare cases, such as a loose gas cap, the light may turn off after a few days of driving if the issue is resolved. However, most check engine lights indicate a mechanical or electrical fault that requires professional repair to reset.
