An illuminated check engine light doesn’t necessarily mean that your engine is on the verge of complete disaster. But you should still visit the shop for computerized diagnostics so that any emerging issues can be taken care of before they escalate and cost more to fix. At A-1 Automotive, our local mechanics specialize in check engine light repair in the greater Portland, OR area. Here are six common reasons that the check engine light turns on.
Failing Spark Plugs
For optimal engine performance and gas mileage, you need your spark plugs to be in strong condition. Symptoms of faulty spark plugs include trouble with getting the car to start, as well as decreasing acceleration.
Faulty Mass Airflow Sensor
Healthy MAF sensors are important because they help to ensure that fuel is properly injected with incoming air. Signs of a bad MAF sensor include hard starts, worsening acceleration, and rough idling.
Bad Catalytic Convertor
Your catalytic converter does the important job of turning dangerous compounds in the engine’s emissions into safer gasses before they’re released into the surrounding air. Signs of a catalytic converter problem are a smell similar to rotten eggs, as well as dark exhaust smoke.
Failing Oxygen Sensor
O2 sensors keep tabs on the amount of unburned oxygen within the exhaust system. When there’s trouble with an O2 sensor, a catalytic converter problem may ensue.
Bad Battery/Charging System
A failing battery can cause low voltage at the computer. In turn, the check engine light may come on.
Gas Cap is Loose/Missing
If your gas cap is loose or missing, then fuel could evaporate before it is directed to your engine. Though it may seem strange, a loose/missing gas cap sometimes triggers the check engine light.
