According to recent research, more than 9 million Americans ignore their check engine lights for 90 days or more. Though most don’t see it as a big deal, it puts their safety at risk and increases the chances of severe engine damage. The most common reasons for a check engine light (and a call for BMW repair in Chicago) are explained here.
A Faulty, Missing or Loose Gas Cap
This is a surprisingly common reason for the check engine light to come on. A gas cap prevents fuel from evaporating and it keeps your car’s fuel system at the correct pressure. If the cap is missing or broken, replace it right away.
A Failed Oxygen Sensor
This component monitors unburned oxygen and fuel levels. A broken oxygen sensor, if not immediately replaced, may cause severe damage to your vehicle’s catalytic converter.
Catalytic Converter Damage
This exhaust part turns carbon monoxide into inert compounds. With proper maintenance, catalytic converter issues are easily prevented. Low performance and diminished fuel economy are the most common symptoms of catalytic converter failure.
MAF Malfunctions
The MAF (mass airflow) sensor regulates the air going into the engine. If your MAF has failed, you may see reduced fuel mileage, starting problems, and stalling.
Vacuum Leaks
Your car’s vacuum system controls various functions. Unfortunately, vacuum hoses crack and dry out with time and exposure to the elements. A vacuum leak can easily trigger a check engine light, but they can be avoided with regular maintenance and BMW repair in Chicago.
