Common Issues that Cause the Check Engine Light to Turn On

When your check engine light comes on, it doesn’t automatically mean that your engine is on the verge of disaster. However, you should get to the shop ASAP for computerized diagnostics so that any emerging issues are pinpointed and addressed before they escalate. At All Tune & Lube, our local mechanics specialize in check engine light repair in the greater Austin, TX area. Here are six common reasons the check engine light comes on.
Bad Catalytic Convertor
The catalytic converter turns hazardous compounds into safer gasses before they’re let out into the atmosphere. Symptoms of a catalytic converter problem include dark exhaust smoke, poor acceleration, and a smell like rotten eggs.
Faulty Oxygen Sensor
O2 sensors keep tabs on the quantity of unburned oxygen in the exhaust system. Problems with an O2 sensor can cause increased emissions, worsening gas mileage, and trouble with the catalytic converter.
Failing Spark Plugs
Healthy spark plugs play an integral role in keeping your engine running smoothly. Signs of bad spark plugs include hard starts and decreasing acceleration.
Trouble with Battery/Charging System
With a faulty battery there may be low voltage at the computer. This could then cause your check engine light to come on.
Faulty Mass Airflow Sensor
Symptoms of a mass airflow sensor problem include difficult starting, worsening acceleration, and rough idling. Mass airflow sensors monitor the amount of air entering the engine, so issues with them should be promptly addressed.
Gas Cap is Loose/Missing
A loose/missing gas cap can let fuel evaporate before you get the chance to run on it. While this might not indicate a mechanical problem with your engine, it may still trigger the light.
