Check Engine Light Diagnostics

So, that dreaded Check Engine light is on? It could be a number of issues causing the light to illuminate. It might something small, like a fuse, or it could be something more serious. Whatever it is, you need to get it diagnosed by individuals that have the right tools to diagnose the underlying problem.

The most common reasons your Check Engine light might come on are:

  • Gas Cap is loose – this happens a lot. If you have to make sure your gas cap is screwed on tight so that fumes do not escape and mess with the sensors.
  • Oxygen Sensor – this is very common and happens in older cars. But a faulty oxygen sensor makes the emissions system not work correctly.
  • Spark Plugs – failing spark plugs cause engine misfires which always results in the Check Engine light to turn on
  • Catalytic Converter – there might be a problem in the catalytic converter, which causes emissions problems.
  • Other sensors – modern vehicles rely on a myriad of sensors to keep your vehicle operating at an optimal level. If any of them go faulty, the Check Engine light will illuminate.
