Why is My Hyundai Check Engine Light On?

1000 × 430

When your Hyundai check engine light has come on, the problem you’ll have to confront could be either big or small. Sometimes you’ll be able to solve your problem on your own, but on other occasions, you may need the help of an expert. Fast action is the only guaranteed way to prevent long-term, lasting damage to your vehicle, so don’t hesitate to contact Oak Lawn Happy Hyundai with questions.

What to Do If Your Check Engine Light is On

If you notice your check engine light when you’re cruising the Tinley Park and Downers Grove streets, act quickly to assess the immediate threat posed by the situation:

  • Check your other dashboard gauges to look for any indication of a more serious problem.
  • If your vehicle appears to be overheating, if your oil pressure is high, or if you notice a loss of power, pull over right away and talk to an expert.
  • If you think there’s a major issue, or if you just want to be certain, you should plan to schedule service right away.

If you don’t notice any drastic changes in performance or behavior, investigate the common causes detailed below.

Common Causes of a Lit Check Engine Light

Next, check to see if these common issues are triggering your check engine light:

  • Sometimes, the solution is as simple as tightening your loose gas cap or replacing your spark plugs. Both of these problems are easy enough to take care of on your own, so you should check for these solutions first.
  • If you’re towing or carrying lots of cargo, it’s a good idea to lighten your load and see if this solves the problem.
  • Wondering how to tell if a spark plug is bad? Rough idling, poor acceleration, and problems starting your engine are all common indicators. If you notice any of these in conjunction with your check engine light coming on, replace your plugs and see if the issue persists.
  • At other times, the issue could be your oxygen sensor. This could be the cause if you notice declining performance or increased fuel consumption when your check engine light comes on.
  • Unlike the other common causes we’ve listed here, replacing an oxygen sensor can be expensive and difficult. It’s best to take your vehicle into a trusted service center.

Should I Have My Vehicle Towed?

If none of these common solutions causes your check engine light to turn off, or if it returns shortly after disappearing, you’ll definitely want to have an expert fix the problem. Towing will only be necessary if you’ve noticed some other serious problem, but either way, you’ll want to act quickly. In emergencies, Hyundai Roadside Assistance may have you covered.

When you take your vehicle into our Hyundai service center, we’ll use specialized technical equipment to read your Hyundai check engine code and determine the exact source of the problem. It’s that simple.
