   my check engin light on but car run fine should i be worry

   Not necessarily, but you shouldn't ignore it either.

   If your check engine light is on steadily and the car is running normally, it's often safe to drive for a short time while you arrange to have it checked. The light means the car's computer has detected a problem, but it isn't always an emergency. Common causes include:

   • A loose or faulty gas cap.
   • A worn oxygen sensor.
   • A faulty mass airflow sensor.
   • An emissions-related issue.
   • A minor ignition or fuel system problem.

   However, if the check engine light is flashing, that's much more urgent. A flashing light usually indicates an engine misfire that can damage the catalytic converter. In that case, avoid driving if possible and have the car inspected as soon as you can.

   Here are a few things you can do:

   1. Check that your gas cap is tight. If it was loose, tighten it and drive for a day or two to see if the light goes off.
   2. Pay attention to any new symptoms, such as rough idling, reduced power, unusual noises, or poor fuel economy.
   3. Have the diagnostic trouble codes read with an OBD-II scanner. Many auto parts stores will read the codes for free.

   If you tell me:

   • the year, make, and model of your car,
   • whether the light is steady or flashing, and
   • if you've noticed any other symptoms,

   I can help you narrow down what the problem is likely to be.

   can i check the code myself without going to mechanic

   Yes. You can check the code yourself with an OBD-II scanner, and it's usually straightforward.

   Here's how:

   1. Get an OBD-II scanner. Basic models are inexpensive, and Bluetooth adapters that connect to your phone are also common.
   2. Find the OBD-II port. It's typically under the dashboard on the driver's side, near the steering column.
   3. Turn the ignition on. Depending on your car, you may turn the key to the "On" position without starting the engine, or simply turn the car on.
   4. Plug in the scanner and follow its prompts to read the diagnostic trouble codes (they'll look something like P0420 or P0301).
   5. Look up the code or tell me what it is, and I can explain what it means and what the likely causes are.

   A few tips:

   • Don't clear the codes right away. Clearing them also erases diagnostic information that can help identify the problem. It's better to record the codes first.
   • A code tells you where the computer detected a problem, but it doesn't always identify the exact failed part. For example, an oxygen sensor code doesn't always mean the oxygen sensor itself needs replacing.

   If you don't own a scanner, many auto parts stores will read the codes for free.

   What is the year, make, model, and engine of your car? I can also recommend a scanner that's a good fit for your vehicle and budget.
