Most vehicle owners know that if they want to keep their current car a reliable source of transportation, it is important to take good care of it. In spite of keeping up with routine engine service, when the “Check Engine” light starts to glow on their dash, anxiety starts to fill their mind. What is happening under the hood? And what causes the “check engine” light to come on? Their biggest fear is that a major engine repair could cost thousands of dollars.

Just remember that the “Check Engine” sensor is part of the on-board diagnostic system that is constantly monitoring engine performance, such as engine speed (RPMs), air to fuel ratio, and ignition timing. If a “fault” within the system is detected, whether big or small, the “check engine” light will illuminate.

So what causes the “Check Engine” light to come on? Here are some of the main causes to consider:

  1. Damaged Gas Cap – If the gas cap is loose or cracked, fuel vapors leak out and can throw the whole fuel system off, reducing gas mileage and increasing toxic emissions. Tightening or replacing the gas cap may resolve the problem.
  2. Faulty Oxygen Sensor – The oxygen sensor monitors the unburned oxygen from the exhaust, and how much fuel is burned. A faulty sensor doesn’t send the right data to the computer, which then reduces gas mileage and increases emissions.
  3. Failing Catalytic Convertor – The catalytic convertor reduces exhaust gases by converting carbon monoxide and other harmful materials into harmless compounds. If it fails, gas mileage will decrease and loss of power when you try to accelerate.
  4. Faulty Mass Airflow Sensor – This sensor tells the car's computer to add the proper amount of fuel based on the air coming through to the engine. If this sensor fails (most failures are because of a clogged air filter), toxic emission will increase, your car may stall, and gas mileage will decrease.
  5. Dirty Spark Plugs and Wires – The spark plug provides a gap for a spark to jump across and initiates combustion in your engine. If they are starting to go bad, replacing them is an easy fix.

A word of advice: Take care of recommended engine service items to help prevent small engine problems turn into a costly engine repair.
