Why Is My Check Engine Light On? Part 2
You’re driving home from work when the worst happens — your check engine light turns on. For many drivers this could mean not driving your car for a few days or bringing it to the mechanic, but often the issues that lead to this signal are small and can be fixed quite easily.
As Jalopnik recently pointed out, the check engine light is one of the most frustrating and needlessly confusing parts of a vehicle because the light could mean a wide variety of things. Check out our first engine light blog post for our first three reasons your light could be on, then keep reading to learn the final two:
It’s Time to Replace the Mass Airflow Sensor
The mass airflow sensor measures the amount of air entering the engine. It does this to determine how much fuel is needed for your engine to run efficiently. If you don’t replace this sensor, you can cause damage to the spark plugs, the oxygen sensors, or even the catalytic converter (which can also turn the light on). Additionally, you will experience reduced performance and fuel economy
Spark Plugs or Plug Wires Are Giving Your Trouble
Spark plugs ignite the air and fuel mixture within the combustion chamber of your car. The spark plug wires then deliver the spark from the ignition coil back to the spark plugs. If you continue to drive with this issue, your car will experience poor performance and reduced fuel economy. Worn plugs and plug wires can also lead to clogged catalytic converter as well as damage to ignition coils and O2 sensors
If you are unsure how to fix the problems above, feel free to bring your car in to our service department to have it checked for any of these issues!
