A check engine light or malfunction indicator lamp is a tell-tale that a computerized engine-management system uses to indicate a malfunction. Found on the instrument panel of most automobiles, it usually bears the legend engine, check engine, service engine soon, maintenance required. The light generally has two stages, steady indicating a minor issue and flashing indicating a sever issue Below are a few reasons your check engine light may be on. 
  • One Sensor has a Loose Electrical Connection or is Damaged. 

  • Loose or Damaged Fuel Cap. Today’s modern cars, trucks and SUV’s are very carefully monitored for fuel economy and emissions. 

  • Damaged O2 sensor. The emissions system on your vehicle is highly complex. 

  • Catalytic Converter is Clogged. While the O2 sensors monitor exhaust gases, the catalytic converter is designed to filter exhaust before it heads out the tailpipe.

  • Air Filter or Fuel Filter is Dirty. Routine service and maintenance are critical for your vehicle to operate correctly and efficiently. 

  • Mass Air Flow Sensor is Damaged. You’re probably seeing a pattern here. In reality, most check engine lights are triggered due to fuel or emissions system issues.

  • Engine has Oil Lubrication Issues. While the top six reasons above can be easily resolved and diagnosed in most cases, this one is rather tricky
