| Light Behavior | What It Indicates | Recommended Action |
| Solid amber light | A detected fault that needs professional diagnosis — not immediately dangerous in most cases | Schedule a diagnostic appointment within the next few days |
| Flashing or blinking light | An active, serious misfire that is damaging the catalytic converter in real time | Stop driving as soon as safely possible — seek immediate service |
| Light comes on and off intermittently | An intermittent fault that the system has detected and logged — may not be currently active | Schedule diagnosis promptly — intermittent faults are harder to catch if ignored |
| Light on with other warning lights | Multiple system faults — potentially serious | Do not continue driving — contact Fairway Automotive immediately |
It depends entirely on whether the light is solid or flashing and whether any other symptoms are present. A solid check engine light with no other symptoms or drivability issues is generally safe to drive on for a short period while scheduling a diagnostic appointment. A flashing check engine light, or a solid light accompanied by rough running, loss of power, overheating, or unusual smells, indicates a condition serious enough to warrant stopping driving immediately and contacting Fairway Automotive for same-day service.
Yes — in some cases. If the condition that triggered the fault code resolves itself — such as a gas cap that was loose and then properly tightened — the system will detect that the fault is no longer present and clear the light after several successful drive cycles. However, the fault code remains stored in the vehicle’s diagnostic memory and will reappear if the condition returns. A light that turns off without a confirmed repair should still be professionally scanned to confirm the underlying cause has genuinely resolved rather than temporarily subsided.
Diagnostic fees vary based on the complexity of the fault and the time required to accurately identify the root cause. Fairway Automotive provides transparent diagnostic pricing and explains all associated costs before any work begins. In many cases, diagnostic fees are applied toward the cost of the repair when the customer proceeds with the recommended service. Contact Fairway Automotive directly for current diagnostic pricing for your specific vehicle.
Clearing the fault code without addressing the underlying cause does not fix anything — it simply resets the warning light temporarily. The fault will reappear once the system completes enough drive cycles to detect the same condition again. More importantly, clearing codes before a state emissions inspection will cause the vehicle to fail — inspectors check for recently cleared codes as well as active faults. The only permanent solution to a check engine light is diagnosing and repairing the underlying cause.
