My Check Engine Light Is On, Now What?

The check engine light should never be ignored. A flashing light indicates a more urgent and serious problem. This light indicates that there is an issue with your vehicle’s emission, fuel, or ignition systems. Often when the light first comes on the potential repairs are minor, and less expensive. Putting off maintenance of what starts as a minor issue could lead to bigger and more expensive problems down the road.

When your check engine light is on, don’t hesitate to bring your vehicle to Accurate Service and have one of our automotive technicians evaluate the problem and provide an honest estimate for repairs. Remember, a delay in car diagnostic or necessary engine repair can make the problems and costs escalate quickly.

Note: Your car will not pass emissions with the check engine light on.  You need to bring it to the shop for a check engine light diagnostic and we can tell you what’s going on and help you with any necessary repairs.

There are several possible causes of a steady or flashing check engine light including (but not limited to):

  • A loose gas cap
  • Failing oxygen sensor
  • Bad spark plug/ignition coil
  • Bad spark plug wires
  • Bad mass air flow sensor
  • A problem with the catalytic converter
  • Excessive gas consumption or release of pollutants
  • Engine vacuum leak
  • EGR valve problem

Before stressing over a check engine light, check your gas cap to make sure it is properly and tightly secured. If it is secure, and the light is still on, give us a call and we will help you take care of the rest.
