Reasons your check engine light may be on: 

  • Oxygen Sensor – The oxygen sensor (aka O2 sensor) measures the amount of unburnt oxygen in a car’s exhaust system. Any vehicle will run with a bad O2 sensor; however, be aware that your car will burn more fuel than usual. Leaving a bad O2 sensor in your vehicle can damage components like the spark plugs and the catalytic converter. 
  • Loose Gas Cap – One of the most common reasons for a check engine light to come on is a loose gas cap. If you have just filled up your ca and your check engine light turns on you may want to pull over and check your gas cap. You may need to simply tighten it or it may need to be replaced.
  • Catalytic Converter Failure – This is a pretty simple part to replace or have repaired. Remember, by receiving regular maintenance (such as oil changes) on time is key to keeping your car’s catalytic converter in tip top shape.
  • Spark Plug/Ignition Issues – You may have worn or fouled plugs that can cause a variety of issues. Issues including an engine misfire and hesitation under heavy acceleration. A worn coil can exhibit the same symptoms, and can cause the car to shut off unexpectedly. If this has happened to you then this may be your issue.
  • Spark Plug Wires – If your vehicle exhibits a rough idle, a noticeable drop in engine performance, and lower gas mileage then you may be experiencing bad spark plug wires.
  • Mass Airflow Sensor Failure – You may be experiencing MAF failure. The signs of an MAF failure include a rough idle, trouble starting, and a sudden change in the position of the throttle pedal. If you notice a reduction in your gas mileage or your vehicle stalls out these are signs that indicate an MAF problem as well.
  • Dead Battery
  • Vacuum Leak – Vacuum hoses can dry out and crack as they age. If you live in extreme heat or cold then the hoses are more likely to have issues. Climate is the most common cause of vacuum leaks. It’s best to have a professional investigate your vacuum lines to trace the source of the leak.
