What are common issues that cause the check engine light to turn on?

by Integrity Auto Care • 27 February 2025
Seeing the check engine light illuminate on your dashboard can be concerning, as it signals that something is wrong with your vehicle. While some issues may be minor, others require immediate attention to prevent further damage. At Integrity Auto Care, we provide expert check engine light diagnostics and repair in the greater South Beloit, IL area. Here are five common causes of an illuminated check engine light. Faulty Oxygen Sensor Oxygen sensors monitor the level of unburned oxygen and help regulate the air-fuel mixture for optimal combustion. Over time, this sensor can become dirty or fail, causing incorrect readings that affect fuel-efficiency and emissions. A faulty oxygen sensor can lead to poor gas mileage and increased emissions, so replacing it promptly is important. Malfunctioning Mass Airflow Sensor The mass airflow (MAF) sensor measures the amount of air entering the engine to ensure the proper air-to-fuel ratio. If the sensor is dirty or fails, the engine may receive too much or too little fuel, leading to rough idling, reduced power, and poor fuel-economy. A malfunctioning MAF sensor can cause the check engine light to turn on, and replacing it can restore proper engine function and efficiency. Failing Catalytic Converter The catalytic converter plays a critical role in reducing harmful emissions by converting toxic gases into less harmful compounds. If it becomes clogged or fails, your vehicle’s performance may suffer, and emissions will increase. A failing catalytic converter can lead to reduced acceleration and poor fuel-economy. Replacing a damaged catalytic converter is necessary to maintain proper engine function and meet emissions standards. Bad Spark Plugs or Ignition Coils Spark plugs and ignition coils are responsible for igniting the air-fuel mixture in the engine’s cylinders. When they wear out or fail, misfires can occur, leading to reduced power, rough idling, and difficulty starting the engine. A check engine light caused by faulty spark plugs or ignition coils should be addressed quickly. Loose or Faulty Gas Cap One of the simplest reasons your check engine light might come on is a loose or damaged gas cap. The gas cap seals the fuel system If it’s not properly tightened, fuel may evaporate before you get the chance to run on it.

Common Warning Signs of Brake Trouble that You Shouldn’t Ignore

by Integrity Auto Care • 26 December 2024
Your vehicle’s brakes are a critical safety component, and any issue with them can compromise your ability to stop effectively. Recognizing the signs of brake trouble early can prevent accidents and higher repair costs. At Integrity Auto Care, we provide expert brake repair in the greater South Beloit area. Here are five signs of a brake problem. Squealing or Grinding Noises One of the most common signs of brake trouble is unusual noises when you apply the brakes. Squealing, screeching, or grinding sounds can indicate that your brake pads are worn down and need replacement. In some cases, grinding noises may suggest that the brake pads have worn completely, causing metal-to-metal contact with the rotor. Ignoring these sounds can lead to more extensive damage to your braking system and reduced stopping power. Soft Brake Pedal If your brake pedal feels soft or your braking system seems less responsive, it’s a clear sign of trouble. This issue could be caused by a brake fluid leak or air in the brake lines. Reduced responsiveness can compromise your ability to stop quickly, especially in emergency situations, making it crucial to have your brakes inspected and repaired as soon as possible. If your car is leaking brake fluid, you’ve got a major safety hazard and should get towed to the shop instead of driving there. Vibrations Feeling vibrations when applying the brakes is another sign of brake trouble. This issue is often caused by warped brake rotors, which can result from excessive heat. Warped rotors can reduce braking efficiency. Brake Warning Light Vehicles are commonly equipped with a brake warning light on the dashboard, which illuminates when there is an issue with the braking system. If you notice this light on, it’s important not to ignore it. The warning light can be triggered by issues like low brake fluid or a malfunction in the brake system. A professional inspection can determine the exact cause. Pulling to One Side If your vehicle pulls to one side when you apply the brakes, you could be dealing with a stuck caliper. Pulling to one side greatly increases your risk of an accident. Having this issue diagnosed and repaired is essential for maintaining safe braking.
