When the check engine light illuminates, it's often a source of anxiety for drivers. While it doesn’t always indicate a major issue, it's important to address the underlying problem as soon as possible to avoid further damage. At All Tune & Lube, we provide expert check engine light diagnostics and repair in the greater Austin, TX area. Here are five common reasons why your check engine light might come on.
Faulty Oxygen Sensor
If an oxygen sensor fails, the engine’s computer won’t get accurate readings about the air-to-fuel ratio, leading to poor fuel-economy and potentially causing catalytic converter problems. Replacing a faulty oxygen sensor is an easy fix, but ignoring it could lead to more costly repairs.
Loose or Damaged Gas Cap
Believe it or not, a loose or damaged gas cap is one of the more common reasons the check engine light comes on. A gas cap that doesn’t seal properly may allow fuel to evaporate before it is directed to the engine.
Catalytic Converter Issues
The catalytic converter reduces harmful emissions by converting exhaust gasses into less toxic pollutants. As the miles add up, it can become clogged or fail. A failed catalytic converter can lead to decreased fuel-efficiency and increased emissions, so it’s essential to address this problem right away.
Mass Airflow Sensor Failure
The mass airflow (MAF) sensor monitors the amount of air entering the engine and helps determine the proper fuel-to-air ratio. If the sensor fails, your car may experience poor fuel-economy, difficulty starting, or rough idling. Replacing a bad MAF sensor can improve engine performance and fuel-efficiency, so it’s important not to ignore this issue.
Spark Plug or Ignition Coil Problems
Ignition coils and spark plugs work together to ignite the fuel in your engine. Over time, spark plugs can wear out, and ignition coils can fail, leading to misfires, reduced power, and poor fuel economy.
