What is causing my check engine light to flash on?

The check engine light is one of the most important warning indicators on your dashboard. When it illuminates, it means your vehicle’s onboard diagnostic system has detected a problem that needs attention. While the light doesn’t always point to a major issue, ignoring it can lead to more serious and expensive repairs. At Uptown Imports, we provide expert Asian and European check engine light diagnostics and repair in the greater Minneapolis area. Here are four common issues that may cause your check engine light to come on.

 

Faulty Oxygen Sensor

The oxygen sensor plays a critical role in monitoring the level of oxygen in your vehicle’s exhaust system. It helps the engine control module adjust the air-to-fuel ratio for optimal combustion. When the sensor malfunctions, it can reduce engine efficiency and lead to poor fuel economy. A faulty oxygen sensor is a common reason the check engine light is triggered and should be replaced promptly to maintain proper engine performance.

 

Malfunctioning Catalytic Converter

The catalytic converter is responsible for reducing harmful emissions by converting exhaust gases into less harmful substances. If the converter is clogged, damaged, or failing, your vehicle may experience reduced performance or increased emissions. A bad catalytic converter is a serious issue and will cause the check engine light to come on. 

 

Worn Spark Plugs or Ignition Coils

Spark plugs and ignition coils are essential for starting your engine and keeping it running smoothly. When these components wear out, the engine may misfire, idle roughly, or lose power. These symptoms will usually be accompanied by the check engine light. Replacing spark plugs and ignition coils as part of regular maintenance can help prevent this issue and keep your engine running efficiently.

 

Problems with the Mass Airflow Sensor

The mass airflow sensor monitors the amount of air entering the engine and helps regulate the fuel injection system. If it becomes dirty or malfunctions, the engine may struggle to maintain the correct air-to-fuel ratio. This can lead to sluggish acceleration, stalling, and an illuminated check engine light.
