If your check engine light turns on, you’ll want to get to the shop for diagnostics. This will give you the best chance to identify and resolve the problem before it escalates and potentially leaves you stranded. At Austin Auto Repair, we provide expert check engine light diagnostics and repair in the greater Austin, TX area. Here’s a look at five common check engine light triggers.

Failing Mass Airflow Sensor

The mass airflow sensor measures the amount of air entering the engine, aiding in determining the appropriate fuel-to-air ratio. A malfunctioning sensor can lead to poor fuel-efficiency, stalling, or rough idling. 

Catalytic Converter Issues

The catalytic converter is tasked with converting harmful gasses into less harmful substances. As the miles add up, it can become clogged or fail, causing the check engine light to illuminate. Ignoring catalytic converter issues can lead to decreased performance and increased emissions.

Failing Oxygen Sensor

The oxygen sensor plays a crucial role in monitoring the amount of oxygen in your vehicle's exhaust gasses. A malfunctioning sensor can lead to decreased gas mileage, engine hesitations, and increased emissions.

Ignition System Problems

A malfunction in the ignition system, such as a faulty spark plug or ignition coil, can trigger the check engine light. Issues in the ignition system can lead to poor fuel efficiency, rough idling, and difficulty starting the vehicle. 

Loose or Faulty Gas Cap

Although it might sound strange, a loose or damaged gas cap is a common cause of the check engine light illuminating. A loose cap can allow fuel vapors to escape, triggering the light. After each time you fill up, it’s important to make sure that the gas cap is returned to a secure position. Otherwise, fuel might evaporate before you get the chance to use it.
