The check engine light can illuminate for a variety of reasons, ranging from minor issues to more serious problems. At All Tune & Lube, we provide expert check engine light diagnostics and repair in the greater Austin, TX area. Our local mechanics will accurately identify the issue and then can flawlessly fix it. Here’s a look at some of the most common reasons that the check engine light turns on.
Loose or Faulty Gas Cap
A loose or damaged gas cap can lead to an evaporative emissions system leak, causing the check engine light to come on. This is one of the most common and easiest issues to fix.
Oxygen Sensor Issues
Oxygen sensors monitor the level of oxygen in the exhaust gasses. When they fail or become dirty, it can affect fuel efficiency and emissions, triggering the light.
Catalytic Converter Problems
Issues with the catalytic converter, such as a clog or failure, can cause the light to illuminate. Signs of a malfunctioning catalytic converter include worsening acceleration and a smell similar to rotten eggs.
Mass Airflow Sensor (MAF) Problems
The MAF sensor measures the amount of air entering the engine, which is critical for proper fuel mixture. A malfunctioning MAF sensor can affect engine performance.
Spark Plug and Ignition System Issues
Problems with spark plugs, spark plug wires, or the ignition coil can lead to misfires in the engine and trigger the check engine light.
Vacuum Leaks
Leaks in the vacuum system can disrupt the air-to-fuel ratio and cause the check engine light to come on.
Thermostat Issues
A faulty thermostat can affect engine temperature and cause the light to illuminate. Overheating can lead to engine damage, so cooling system issues should always be addressed ASAP.
Exhaust System Leaks
Leaks in the exhaust system, such as a cracked exhaust manifold or a damaged exhaust pipe, can lead to abnormal emissions and trigger the light.
