What It Means When Your Check Engine Light Comes On

Chuck's Auto RepairDo you know what to do when the ‘check engine light’ shows up on the dashboard? You’ll likely know something is wrong, but what do you do once you pull over? If the check engine light comes on, then your car may have one of the following problems. Needless to say, get your vehicle to an auto repair service ASAP.

1. The Spark Plugs Are Worn

The spark plugs create an ignition that enables the air/fuel mixture in the vehicle’s combustion chamber. Worn sparks reduces fuel economy and can also damage the ignition coils or cause the catalytic converter to become backed up.

2. The Mass Airflow (MAF) Sensor Is Damaged

The MAF sensor measures and facilitates the amount of air flow into the engine. When the MAF is compromised, damage to the spark plugs, catalytic converter, or O2 sensors may soon follow.

3. Faulty Catalytic Converter

The catalytic converter performs a vital eco function by converting harmful carbon monoxide into carbon dioxide. If not fixed, this can force your engine to work at a higher temperature. It may also cause your car to fail its next emissions test.

4. The Oxygen Sensor Needs Replacing

This component measures the amount of unburned oxygen in the exhaust system. A faulty sensor can result up to a 40% decrease in fuel economy.

5. Gas Cap Is Loose

The gas cap is so much more important than most people realize. If the cap is loose or missing altogether, your car will lose fuel through evaporation. For you, that means more money wasted at the pump.
