What Is the CHECK ENGINE or SERVICE ENGINE SOON Light?

Modern vehicles are engineered to run with a very precise tune to ensure maximum fuel efficiency and minimum emissions. When your car’s onboard computer senses that your car is no longer running within this tune, your Check Engine light will come on.

What Is the FREE Check?

When you come into our shop with your Check Engine light lit, we will do a FREE check to figure out what tripped the light to come on. This means that we will hook your car up to our computer and figure out what the car’s computer has identified as a problem. This is a great starting place, and we can often give you some idea about what might be the cause and how much it might cost to repair, but to determine the actual cause typically involves a more extensive diagnostic, which is generally not free.

CHECK ENGINE Light Common Codes

Although there are potentially hundreds of codes that could be triggering your car’s Check Engine light. Some of the more common ones we see are:

  • Problem with the Mass Air Flow—generally accompanied by decrease in power
  • System running too lean—may case a hesitation/surge during acceleration or spark-knock in the engine.
  • System running too rich—may experience misfires
  • Cylinder misfire—stumbling, rough idle, or hesitate
  • Catalyst system efficiency below threshold—not likely to cause performance issues, but may lead to damage to your exhaust system
