Understanding Your Check Engine Light At Cook Tire

The check engine light is one of the most important dashboard warning lights in your vehicle. When it comes on, it can mean something as simple as tightening the gas cap or something more serious like a misfiring engine. If you’re in East Texas—Lufkin, Nacogdoches, or Livingston—Cook Tire is here to help you understand what’s wrong and how to fix it.
Why Your Check Engine Light Illuminates
There are many reasons why the check engine light illuminates. Some are minor issues, while others require immediate attention. Your vehicle’s onboard diagnostics system (OBD II) continuously monitors the engine and control system. When it detects a fault, it triggers the light. You can bring your vehicle to Cook Tire for a professional diagnosis.
Common Causes Of A Check Engine Light
Loose Or Faulty Gas Cap
- Believe it or not, something as simple as the gas cap being loose can cause your check engine light to turn on. If your gas cap isn’t sealed properly, it can affect the emissions system and trigger a fault. Try tightening the gas cap and see if the light goes off after driving for a bit.
Faulty Oxygen Sensor
- A faulty oxygen sensor can cause engine issues and reduce vehicle performance. The sensor measures the amount of air and fuel in the exhaust to ensure efficient combustion. If it malfunctions, it can lead to poor fuel economy and even damage your catalytic converter.
Catalytic Converter Issues
- The catalytic converter helps reduce harmful emissions. If it becomes clogged or damaged, it can lead to poor fuel efficiency, increased emissions, and a loss of power. Cook Tire can inspect and replace your catalytic converter if needed.
Spark Plug or Spark Plug Wires
- Worn-out spark plug wires or faulty spark plugs can lead to a misfiring engine, rough idling, and reduced fuel economy. Replacing them on time can help improve overall vehicle performance.
Engine Problems and Low Oil Pressure
- Some engine problems can be severe, especially if related to oil pressure. A drop in oil pressure can lead to excessive friction and possible engine damage. If you notice unusual noises, loss of power, or smoke, bring your car to Cook Tire for an inspection.
Check Engine Light Flashing Vs. Steady Light
If your check engine light is flashing, it’s a sign of a serious problem, such as a misfiring engine that could damage the catalytic converter. You should avoid driving and have your vehicle checked immediately. A steady light, on the other hand, means there’s an issue that needs attention, but it’s not an immediate emergency.
