Seeing the check engine light illuminate on your dashboard can be concerning, and for good reason. While it doesn’t always mean a major issue, it’s best to promptly visit the shop for diagnostics so the problem can be identified and addressed before it worsens. At Absolut Autoworks, we provide expert check engine light repair in the greater Sterling, VA area. Here’s a look at five common check engine light triggers. Failing Catalytic Converter The catalytic converter plays a crucial role in reducing harmful emissions by converting pollutants into less harmful substances. If it begins to fail, the check engine light will likely illuminate. Symptoms of a failing catalytic converter include reduced engine performance, poor fuel-economy, and a sulfur-like odor. Faulty Oxygen Sensor The oxygen sensor monitors the amount of unburned oxygen in your vehicle’s exhaust system and helps regulate the air-fuel mixture for optimal combustion. A failing oxygen sensor can cause poor fuel-efficiency and increased emissions. Replacing a faulty oxygen sensor promptly can improve performance and help prevent issues with the catalytic converter. Malfunctioning Mass Airflow Sensor The mass airflow (MAF) sensor measures the amount of air entering the engine and helps adjust the fuel mixture accordingly. A malfunctioning MAF sensor can cause rough idling, stalling, and reduced fuel-efficiency. Replacing the sensor as needed can restore engine performance. Loose or Faulty Gas Cap One of the simplest and most overlooked reasons for a check engine light is a loose or faulty gas cap. The gas cap helps seal the fuel system. If it’s not tightened properly or is damaged, fuel may evaporate before you get the opportunity to use it. Faulty Spark Plugs Spark plugs play a critical role in igniting the air-fuel mixture within the engine. Over time, they can wear out, leading to misfires, rough idling, and sluggish acceleration. If the check engine light turns on due to spark plug issues, replacement can restore smooth engine operation.

Regular maintenance and preventive care can help you avoid costly repairs and inconvenient breakdowns. At Absolut Autoworks, we provide expert auto maintenance in the greater Sterling, VA area. Here are five maintenance tips to keep your engine in great condition. Change the Oil and Oil Filter Regularly Oil is essential for lubricating the engine’s moving parts and preventing excessive wear and tear. Over time, oil breaks down and collects dirt and debris, reducing its effectiveness. Changing the oil and oil filter at the manufacturer-recommended intervals promotes proper lubrication and helps extend engine life. Using the right type of oil for your vehicle is also crucial for optimal performance. Properly Maintain the Cooling System The cooling system prevents the engine from overheating, which can lead to serious damage. Ensuring that the coolant levels are adequate and that there are no leaks in the system is vital. Flushing the coolant periodically, as recommended in your owner’s manual, helps remove built-up contaminants and keeps the radiator and other cooling components functioning properly. Replace Air and Fuel Filters Air and fuel filters play a crucial role in maintaining engine efficiency. A clean air filter ensures that the engine receives the right amount of air for combustion, while a functioning fuel filter prevents impurities from entering the engine. Replacing these filters as recommended helps improve fuel-economy and overall engine performance. Inspect and Maintain the Spark Plugs Spark plugs are responsible for igniting the fuel-air mixture in the engine’s cylinders. Worn or dirty spark plugs can lead to poor fuel-efficiency, rough idling, and difficulty starting the car. Regularly checking and replacing spark plugs according to the manufacturer’s schedule helps keep the engine running smoothly and improves overall performance. Don’t Ignore Warning Signs An illuminated check engine light, unusual noises, or decreased fuel-efficiency can indicate potential engine problems. Addressing these issues promptly can help prevent further damage and costly repairs. Routine inspections by the mechanic can help detect problems early and keep your engine in top condition.
