Few things make drivers more uneasy than the check engine light suddenly appearing on the dashboard. While the light can signal a wide range of issues, it always means your vehicle’s onboard computer has detected something abnormal. Ignoring it can lead to bigger, more expensive problems later on, so it’s best to visit the shop for diagnostics ASAP. At HESCO Automotive & Performance Center, we provide expert check engine light diagnostics and repair in the greater Birmingham, AL area. Here are four common car issues that cause the check engine light to illuminate. Faulty Oxygen Sensor One of the most common reasons for a check engine light is a failing oxygen sensor. This sensor monitors the amount of unburned oxygen in the exhaust and helps the engine adjust its air-fuel mixture. When it malfunctions, the vehicle may burn more fuel than necessary, decreasing fuel-economy and increasing emissions. If left unchecked, a bad oxygen sensor can also damage the catalytic converter. Replacing it promptly helps your engine run efficiently and prevents further complications. Malfunctioning Catalytic Converter The catalytic converter is a vital emissions control component that converts harmful gases into safer emissions. When it begins to fail, the vehicle may experience sluggish performance and decreased fuel-economy. A failing catalytic converter will almost certainly trigger the check engine light. Faulty Spark Plugs/Ignition Coils Spark plugs and ignition coils are essential for igniting the fuel-air mixture in the engine. When they wear out or fail, the engine may misfire, run rough, or struggle to accelerate. These misfires can be quickly detected by the computer system, causing the check engine light to come on. Replacing spark plugs and coils is relatively inexpensive and can restore smooth performance. Problems with the Mass Airflow Sensor The mass airflow (MAF) sensor measures how much air is entering the engine so that the computer can balance the fuel mixture correctly. A failing MAF sensor can cause stalling, poor fuel-economy, and sluggish acceleration. Replacing the sensor usually resolves the problem.

Your vehicle’s braking system is one of its most vital safety features. However, brakes experience significant wear and tear over time. Neglecting maintenance can lead to reduced performance, longer stopping distances, or even brake failure. Fortunately, with proper care and attention, you can keep your braking system operating smoothly for years. At HESCO Automotive & Performance Center, we provide expert brake service in the greater Birmingham, AL area. Here are four tips for maintaining healthy and reliable brakes. Schedule Regular Brake Inspections Routine inspections are key to keeping your braking system in top condition. Most experts recommend having your brakes checked at least once a year—or more often if you notice unusual noises, vibrations, or reduced braking power. The technician can inspect the pads, rotors, calipers, and brake fluid to identify early signs of wear. Catching small problems early helps prevent major issues that could compromise your safety and lead to more expensive repairs. Replace Brake Pads Before They’re Fully Worn Brake pads are designed to wear down gradually, but waiting too long to replace them can cause serious damage to the rotors. If you hear squealing or grinding noises when braking, it’s a clear sign that your pads may be worn out. Replacing them promptly helps ensure consistent stopping power and can extend the lifespan of other components in the system. Properly Maintain Brake Fluid Brake fluid plays a critical role in transferring pressure from the pedal to the braking components. Over time, it can become contaminated with moisture, leading to corrosion and reduced braking efficiency. Check your fluid level regularly and be sure it’s topped off as needed using the type specified in your owner’s manual. It’s also a good idea to have the fluid flushed in accordance with your manufacturer’s guidelines. Address Signs of Trouble Immediately If you notice symptoms like a soft brake pedal, vibrations, pulling to one side, or a dashboard brake warning light, don’t ignore them. Prompt diagnosis and repair by a mechanic can prevent further damage and keep your vehicle safe to drive.
