Dashboard Check Engine Light Diagnostics by Sears Auto

Dashboard with Check Engine light

Why is my Check Engine Light on?

Nothing strikes fear like your check engine light coming on. The symbol you’d like to ignore, but shouldn’t. This warning sign has the potential to keep a minor situation from becoming a major repair — so be sure to listen to your car when it tells you to check the engine.

Tip: Start simple and check your gas cap to make sure it is tightened correctly. This could eliminate any leaking fuel vapors and may turn your check engine light off.

Check Engine Light

There are a number of reasons why your check engine light will turn on, so it is important to bring your vehicle in to get a diagnostic test right away. Here are just a few common reasons:

  • Faulty oxygen sensor
  • Loose or damaged gas cap
  • Failing catalytic converter
  • Failing mass airflow sensor
  • Worn spark plugs

  • Symbols worth getting to know.

    Your dashboard symbols provide essential information about your vehicle — either a sensor is broken, something is wrong or about to go wrong. Knowing what these warnings mean can help determine the severity of the situation.

    • TPMS – Tire Pressure Monitoring System

      If a tires pressure is down 25% or more, your TPMS light will turn on indicating that you need more air in one of your tires.

    • ABS – Anti-Lock Braking System

      While braking in slippery or hazardous conditions, this system prevents your vehicle from skidding out of control — by keeping your wheels from locking up.

    • Brake Light

      The brake light can be triggered from something as simple as your parking brake being engaged to more serious issues stemming from loss of brake fluids.

    • Oil Level

      This light means your oil pressure or oil level is low. Either way, you’ll want to check your oil as soon as possible.
      Oil Change

    • Battery Light

      This light indicates that there is an issue either with your battery or vehicle’s electrical system.

    • Traction Control System

      The traction control light tells you that your traction system has been activated due to slippery driving conditions.

    • Temperature Warning Light

      Your temperature warning light lets you know if your engine is overheating, which could mean your coolant level may be low.
