If your vehicle's “Check Engine” light comes on and stays on while you're driving, that means the On-Board Diagnostics system has detected a problem. It might be a condition that wastes fuel, shortens engine life, or causes excessive air pollution. The source of the problem may be as simple as a missing or broken gas cap or an engine misfire, but if the issue is not addressed, it may lead to more extensive vehicle damage and increasingly expensive repairs.

 What If The "Check Engine" Light Stays On?

Don't panic. In most cases, there's no need to pull off the road or stop the vehicle. When you reach your destination, simply check the gas cap to make sure it's on tightly. If you notice the cap is damaged, replace it.

If the Check Engine light does not go out after a few short trips, drive to one of the Mountain View Tire locations for a professional diagnosis. 

What If The "Check Engine" Light Is Blinking?

A blinking Check Engine light indicates a more serious engine problem, such as a catalyst-damaging misfire. In most cases, you can still drive safely, but you should pull into a Mountain View Tire location as quickly as possible. Try not to drive the vehicle at a high speed, while towing excess weight, or while carrying a heavy load until the problem can be corrected.
