Common Check Engine Light Problems that Should Be Diagnosed & Repaired ASAP

The check engine light is one of the most important warning indicators on your dashboard. When it lights up, it means your vehicle’s onboard diagnostics system has detected a problem. While the issue might be something minor, it could also signal a more serious concern that requires immediate attention. Understanding the common reasons why this light comes on can help you take quick action and avoid costlier repairs. At New Life Tires & Auto Repair, we provide expert check engine light diagnostics and repair in the greater Bonita Springs, FL area. Here are four of the most frequent culprits behind a check engine light.
Faulty Oxygen Sensor
Your car’s oxygen sensors monitor how much unburned oxygen is in the exhaust system, which helps manage fuel efficiency and emissions. A failing oxygen sensor can cause the engine to burn too much or too little fuel, reducing gas mileage and increasing emissions. Replacing a faulty sensor is essential to keep your engine running smoothly and efficiently.
Failing Catalytic Converter
The catalytic converter is a critical component of your vehicle’s emissions system. It converts harmful gases into less harmful ones before they exit the exhaust. If it becomes clogged or fails, your vehicle’s performance will suffer. Common signs of a faulty catalytic converter include worsening acceleration and a sulfur-like smell.
Malfunctioning Mass Air Flow Sensor
The mass air flow (MAF) sensor measures the amount of air entering the engine, helping to determine the correct fuel mix. If the sensor fails, it can cause poor fuel-economy, engine hesitation, and stalling. Replacing the MAF sensor can often resolve the issue and restore engine performance.
Worn Spark Plugs or Ignition Coils
Spark plugs and ignition coils are vital for igniting the air-fuel mixture in the engine’s cylinders. When they become worn or damaged, your car may develop symptoms such as rough idling and reduced power. These issues commonly cause the check engine light to come on. Replacing faulty ignition components can improve performance and prevent engine trouble from escalating.
