Common Check Engine Light Triggers
There are few things related to your automobile that can be as disheartening as the check engine light coming on. While many people fear the worst as soon as this light glows, it may calm your nerves that the actual problem may be relatively minor. However, that little issue will grow worse if it is not addressed in a timely manner, so be sure to get to the repair shop right away. In this list of common check engine problems, we start with a worst case scenario.
The catalytic converter is designed to convert hazardous exhaust fumes into less harmful emissions. It will almost never become damaged unless some other part or sensor fails first, which would cause excessive amounts of unburned fuel to travel through it. If the check engine light diagnostics reveal a faulty converter, it is likely the light has been on for some time due to a previous issue, and now you're in for one of the most expensive types of auto repair.
The oxygen sensor is one of the things that can cause a catalytic converter to go bad. This sensor is located in the exhaust system and monitors how much O2 is in the exhaust in order to help dictate how much fuel is sent to the combustion chamber. If it fails or if there is an exhaust leak, it may read excessive oxygen, thus sending more and more gas to the engine, which can ultimately cause catalytic converter damage.
On the other end of the car is the mass airflow sensor, which measures the amount of incoming air and calculates how much should be mixed with the gasoline. A failed MAF sensor can also cause the car to run rich, thus lowering your MPGs and damaging other parts.
Misfiring, which results in lowered fuel efficiency and a rough running engine, is usually caused by dirty or corroded spark plugs or spark plug wires, failing ignition coils, as well as other minor issues. Most misfiring problems can be repaired quickly and inexpensively, as long as they're taken care of quickly.
Broken or Loose Gas Cap
Your best case scenario is if you simply forgot to tighten the gas cap after filling up. A loose, ill-fitting or broken gas cap can result in fuel evaporating out of the filler hose, which will be detected by the vehicle's EVAP sensors, thus triggering the check engine light.
