When the engine light on your vehicle illuminates, it’s your car’s way of telling you something needs attention. Unlike a flat tire or overheating, a flashing dashboard warning light can seem less urgent, but it should never be ignored. In fact, one of the first things you should consider is making an appointment with your dealership’s service department to get it diagnosed.
Consider the Following Steps When You See the Engine Light
Check the Gas Cap
A loose or damaged gas cap is one of the simplest yet most common reasons for that pesky warning light to come on. Problems with the gas cap can affect the fuel system’s pressure, triggering the light. Tighten the cap or replace it if necessary.
Reduce Your Speed and Load
If your light comes on while driving, especially if it’s flashing, it may indicate a more serious issue. Reduce your speed, avoid towing, and minimize your load to prevent potential damage.
Consult With Your Dealerships Service Department
Continuing to drive with the warning light on may increase the chance that you will do serious damage to your vehicle. Regardless of whether the light is steady or blinking, scheduling a diagnostic check with your dealerships service department should be considered. They have the tools and expertise to accurately diagnose and resolve your vehicles issue.
Common Causes for Your Warning Light to Appear
Oxygen Sensor Failure
The oxygen sensor monitors the amount of unburned oxygen in the exhaust system. Due to its position next to hot exhaust gases, this sensor can become damaged over time. A faulty sensor can cause your engine to receive too much or too little fuel.
Catalytic Converter Issues
The catalytic converter helps protect the environment by converting harmful carbon monoxide into carbon dioxide. Failure is often related to neglecting other maintenance, such as replacing a faulty oxygen sensor or spark plugs and may seriously affect your car’s performance.
Faulty Ignition Coil and Spark Plugs
Ignition coils and spark plugs are critical for starting your car and keeping it running smoothly. Wear and tear over time can lead to inefficiency and failure, triggering the light.
Mass Airflow Sensor Malfunction
This sensor measures the amount of air entering the engine to determine how much fuel is needed to run efficiently. A malfunction can result in decreased performance, poor fuel economy, and possible engine misfires.
Preventative Measures
To help avoid unexpected visits to the dealership, regular maintenance is key. Consider following your vehicle’s maintenance schedule, which includes oil changes, air filter replacements, and spark plug inspections. Regular checks can often prevent the issues that trigger your light.
