Check Engine Light

Possible Check (Service) Engine Light Problems

A good day can quickly turn into a bad one if the dreaded check or service engine light in your vehicle suddenly comes on. The issue could be something minor, like a loose gas cap, or it could be a much more serious and costly problem. Your car’s check engine light is a warning that something needs to be serviced or repaired. Ignoring this warning can have devastating consequences – costing you a lot of extra money and hassle in the long run. Below is a list of a few of the possible causes that could illuminate¬†your check engine light.

  • Catalytic converter failure
  • Circuit malfunction
  • Cylinder misfire
  • Faulty oxygen sensor (O2 Sensor)
  • Faulty spark plugs or spark plug wires
  • Insufficient exhaust gas recirculation (EGR) flow
  • Faulty mass air flow (MAF) sensor or MAF circuit
  • Loose or faulty gas cap

Why is it important to bring your vehicle to My Mechanic?

Although most auto parts stores provide a free diagnostic reading when your check engine light comes on, that reading will likely not be sufficient to pinpoint the exact issue that activated the warning light. There are literally hundreds of codes that can trigger your check engine light, and these codes don’t necessarily point to a precise cause of the problem. Rather, they tell technicians where to begin looking for the problem. For that reason, it is important to take your vehicle to a professional automotive repair center if the check engine warning light suddenly comes on. At My Mechanic, we provide a manual inspection in conjunction with a computer diagnosis in order to identify the root cause for the check engine light and make all necessary repairs.
